Warnings and CautionsNote – An absence of specific alerts does not mean that there are no safety risks involved.

Always follow the instructions that accompany a Warning or Caution. The information they provide is intended to minimize the risk of personal injury and/or damage to the equipment. In particular, observe safety instructions that are presented in the following formats:

C Warning – A Warning alerts you to a likely risk of serious injury to your person and/or damage to the equipment. A warning identifies the nature of the risk and the extent of possible injury and/or damage. It also describes how to protect yourself and/or the equipment from this risk. Warnings that appear in the text are repeated at the front of the service manual.

C Caution – A Caution alerts you to a possible risk of damage to the equipment and/or loss of data. A Caution describes how to protect the equipment and/or data from this risk.

Electrostatic Discharge (ESD)Note – For detailed information about ESD, refer to the Trimble Service Provider Reference Manual (P/N 022480-068).

The SPS985 smart antenna was constructed in an ESD-protected environment. Most of the semiconductor devices in the instrument are susceptible to ESD damage.

ESD is generated in many ways. For example, it can be the result of simple contact, the separation of materials, or the normal motion of people working with the device. Depending on the magnitude of the charge, device substrates can be punctured or destroyed by contact with, or by mere proximity to, a static charge. The result can be immediate destruction, early failure of the device, or degradation of device performance.


Chapter 1


To prevent static damage or destruction:

• Take adequate precautions when you handle or service equipment that contains static-sensitive devices.

• Only attempt to service the circuitry in a static-sensitive device if you are thoroughly familiar with industry-accepted techniques for handling such devices.

• Always take adequate measures to prevent the buildup of static charge on work surfaces and on persons handling the smart antenna.

Setting up an ESD-protected workstation

1. Unroll the ESD field service workstation kit and place it, pocket side up, on the workbench.

Charging the Lithium-ion battery

The battery is supplied partially charged. Charge the battery completely before using it for the first time. If the battery has been stored for longer than six months, charge it before use.

Disposing of the rechargeable Lithium-ion battery

Discharge the battery before disposing of it. When disposing of the battery, be sure to do so in an environmentally sensitive manner. Adhere to any local and national regulations concerning battery disposal or recycling.

The EU RoHS initiativeIn July 2006, the European Union restricted the hazardous material content within new products being sold. Primarily this was an effort to reduce lead within products. Many parts within electronic devices contain lead, such as solder on PC boards or within IC's. After the RoHS implementation, manufacturers were required to use alternate materials and soldering methods. Products that were sold before the July 2006 date, have been grand-fathered in, and are not subject to RoHS. Service parts specifically for these products containing lead are permitted as well. Only newly created products intended for sale after the July 2006 date are subject to RoHS.

What RoHS means to Trimble

Trimble has made the commitment to create all new GPS products as lead free and certified RoHS compliant. This includes older products which have been selling prior to RoHS. You will start to see many of the older products converted into RoHS compliant versions. Even though these are older products and it is not required, it is an extremely worthwhile endeavor.

Chapter 1


What RoHS means to Service

There are several very complex issues around the RoHS initiative. The Service Provider must understand and follow these rules:

• Only lead free solder may be used on RoHS compliant products. Most GPS Service Providers have been using Silver solder for several years (AG/SN). Make sure you ONLY use Silver solder for ANY GPS products.

• Parts meant for non RoHS products must NOT be used on RoHS products. Use only those parts shown in the part list for a specific product.

• Parts meant for a RoHS product may not be compatible with a non RoHS product. Use only those parts shown in the part list for a specific product. If the part works in both products, the part list will state that.

• Radio doors, radio boards, and Bluetooth® boards pose special problems as they must also pass type approval. Some parts may not be used in other products due to non compliance with Country regulations. Use only those parts shown in the part list for a specific product.

• Within the part lists, the general rule to identify whether a product is RoHS compliant or not is to look at the short name. For instance, NetRS and R8GNSS are non-compliant products. NetRSR and R8GNSSR are RoHS compliant (shown by the last letter R).

• It is highly recommended that Service Providers have separate inventory location for lead and lead free parts. This might mean a different cabinet or shelf. It is also highly recommended to have RoHS labels available to attach to the individual part. Green dots are a good solution and will help to quickly identify RoHS compliant parts.

• RoHS service parts will be a phase in process for non RoHS products. Use the original part defined for the non RoHS product first. Once these parts are consumed, the new RoHS part will phase in as long as it is FULLY backwards compatible. The old part numbers will then be inactivated. Please, ALWAYS refer to the latest part list.

• RoHS compliant PC boards may be identified by the PB symbol.

• In mid 2007, China will launch its own RoHS initiative. The products that have been certified as RoHS compliant comply with both EU and Chinese regulations.

• Service parts are defined as:

– SPR (Service Part Red) which is allowed in the EU to service an existing product

– SPG (Service Part Green) which conforms to RoHS.

Receiver level part numbers

The part number and serial number labels can be seen on the bottom of the SPS985 Smart Antenna, refer to Bottom connector summary, page 28 as needed. To become fully operational, the receivers are activated at the time of purchase by the Trimble dealer that sold the product to our customer. The initial purchase and additional options purchased are all tracked in the Trimble store of the dealer that sold them. Summary tables of Standard receiver model part numbers, Precision option upgrades and Location option upgrades are shown below:

Table 3.2 Summary of receiver level part numbers - ROW:

Table 3.3 Summary of receiver level part numbers - USA/CAN:

Note – Models designated as USA/Canada and/or ending with part number that has a “5” (Example: 82500-65) have an antenna element that is tuned slightly different then the ROW model part numbers ending in “0” (Example: 82500-60). As per the service parts manual for this product series there are two separate antenna elements available as service part numbers: 88245-10S (USA/Canada) and 82445-00S (ROW). These must be matched properly when they are being replaced during a repair.

B Tip – Whether the product is sold as a USA/Canada or ROW model an “un-activated” receiver does not have L2, Bluetooth or Wi-Fi enabled and therefore since Wi-Fi is not set to its default of Access Point mode, the Wi-Fi LED on the front panel will also not be lit up and access to the web-server will not be available.

Once a receiver is activated by a Trimble dealer a basic set of options are enabled. These cab be seen by using the Wi-Fi web-server and looking at the \Receiver Status\Receiver-Options screen in Figure 3.1.

Figure 3.1 Basic options are shown after activation process for models “with radio”:

• Basic Activation does not enable Rover or Base capabilities such as CMRx & RTCM Input/Output or Transmit.

• Note that the Base and Rover capabilities are reported as OFF in the Accuracy Mode Summary in the upper left.

• The customer will most likely purchase additional options after basic activation.

In the next example 50990-10 Upgrade - Precise Base/Rover, has been applied after Basic Activation as shown in Figure 3.2, page 22.

Chapter 3


MechanicalMechanically the SPS985 Smart Antenna consists of a top and bottom housing and an antenna element with a plastic radome. The radome uses a plastic lock-ring that is screwed onto the top housing to hold it in place. The product itself is the first time Trimble’s HCC group has developed a GNSS receiver that has a form factor that is more in line with what can be dubbed a “Smart Antenna”.

Assembly wise the service technicians need to ensure that all shields and EMI gaskets are properly placed within the receiver as per the service manual re-assembly instructions and that all loctite and torque specifications are followed.

The lower housing contains the Bluetooth/Wi-Fi board and a small oval shaped radome to help radiate the Bluetooth/Wi-Fi signals. The lower housing also contains the keyboard and keypad. the rest of the lower housing contains the RF and power cables and the battery enclosure.

The upper housing contains the power supply and digital board. The antenna element plugs into the digital board via two RF jacks and the antenna radome fits over the top of the receiver and is held in place by a lock-ring.

ElectricalFrom an EMI and radio shielding perspective, the product consists of a special chamber built within the lower housing to encase the Wi-Fi/Bluetooth module and help isolate some if its electrical characteristics from the rest of the other electronic components found inside of the receiver such as the power supply, digital board and radio modules.

Circuit boards

Bluetooth/Wi-Fi board

The Bluetooth/Wi-Fi board assembly (81078-01S) is mounted to the lower housing and is covered by a small white radome. The signal itself is omnidirectional so you do not have to point it directly at another Bluetooth device. The Wi-Fi module itself consists of an 802.11 B/G transceiver. On models that have a 900MHz or UHF radio, there is an RF cable that runs from the back of the Bluetooth board and then runs up and is mounted onto the upper housing where the digital board plugs into it.

On models with “no radio” there is no Bluetooth/Wi-Fi module mounted inside the Bluetooth compartment and no associated outgoing RF cable. With “no radio” models, the external TNC connector does not run to a 900MHz or UHF radio module mounted inside the unit like on the “with radio” models. Instead the TNC RF cable internally runs up to and is mounted onto the upper housing where the internal Bluetooth/Wi-Fi modules cable is normally mounted. On “no radio” models customers must use an external 2.4GHz antenna to receive Bluetooth/Wi-Fi signal.

Front control panel assembly and keypad

The control panel assembly (P/N 81079-00S) is mounted onto a small metal frame. This metal frame then mounts onto the lower housing and holds the keypad (81463-00S) in place. A cable plugs the control panel assembly into the power supply of the receiver.

Power supply board

The power supply board (P/N80091-00S) is mounted on the underside of the top housing where all of the lower housing cables can plug into it, including the power cable from the battery enclosure and the main lemo power cable. The digital board has a 56 pin connector that plugs into the power supply board.

Digital board

The digital board (P/N 80090-00S) controls the processing of the GNNS signals it receivers from the antenna element and it also manages the configuration memory and the memory reserved for data logging. This board is mounted onto the upper-side of the top housing. It has two RF sockets to allow it to be plugged into the antenna element.

Antenna element assembly

Models designated as USA/Canada and/or ending with part number that has a “5” (Example: 82500-65) have an antenna element that is tuned slightly different then the ROW model part numbers ending in “0” (Example: 82500-60). As per the service parts manual for this product series there are two separate antenna elements available as service part numbers: 88245-10S (USA/Canada) and 82445-00S (ROW). These must be matched properly when they are being replaced during a repair.

Radio Modules and adaptor board:

The UHF radio module (P/N 90384-60S) is a wide-band radio module that can cover the entire UHF range of 410MHz through 470MHz. It plugs into a small radio adaptor board (81077-00S) that in turn plugs into the digital board.

The 900MHz models were redesigned so that we now have a “standalone” 900MHz radio module (P/N 80385-00S) rather then a 900MHz board assembly like on past products. This radio module also interfaces to the same small radio adaptor board (81077-00S) in our UHF model and in turn, plugs into the digital board.

Figure 4.2 Bottom diagram of an SPS985:

Each item is marked with a number to indicate its main function, as shown in the following table:

The Lemo port is a 7-pin 0-shell 2-key Lemo connector that supports USB communications and external power input. The Lemo port has no power outputs. The TNC port connector is for connecting a radio antenna to the receivers internal radio. A whip “rubber duck” antenna is supplied with the system. This connector is not used if you are using an external radio receiver. For longer range operation (to provide higher gain and to raise the antenna higher above the ground), you can use a cable to connect an external radio antenna to the TNC port. For more information, refer to the topic “Connecting the receiver to external devices” in the Web Help.

InterfacesF

To interface the UUT to the test computer, perform the following steps:

1. Plug the 7-pin Lemo connector on interface cable P/N 80751 into the UUT.

2. Plug the USB end of interface cable P/N 80751 into a USB port on the test computer.

3. Plug power cord P/N 78651 into power supply78650.

4. Plug the power cord into an AC power outlet.

5. Plug the DC jack from the power supply into the DC jack found on the interface cable.

6. If the UUT doesn’t automatically turn on then press the power button when you are ready.

You should be ready to perform WinFlash Supervisor (WFS) operations now. See Chapter , WinFlash utility for general operations.

Connecting to the Web-Server interfaceThe SPS985 smart antenna does not have a direct RJ45 Ethernet port so it must be linked to a test computer via a Wi-Fi connection to use the Web-Server feature. To do this the test computer must have an 802.11 B/G series Wi-Fi card that is in operational condition and a software utility that will allow you to view and connect to available Wi-Fi devices. There must be an active wireless Wi-Fi network in the shop. To interface to the UUT’s Web-Server, perform the following steps:

1. The UUT must at least be powered up and running and fully activated as a product before trying to interface with Wi-Fi. It does not matter whether the Lemo to USB test cable P/N 80751 is hooked up to the test computer.

2. The UUT must be powered up and running with its Wi-Fi set to its default setting of Access Point mode. When the receiver is in Access Point mode the Wi-Fi LED should be flashing. If if it is not then:

– Once the UUT is powered up, press and hold down the power key for at least 15 seconds.

– Once the satellite LED lights up, let go of the power key and let the UUT continue rebooting.

– When the Satellite, and Wireless LED’s begin to flash, proceed to step 3.

C Warning – On “No Radio” Models (82500 -00, -05) you must have the external antenna (Sales P/N 81004) that is supplied in the kit attached to the TNC connector on the bottom of the unit or the UUT will not receive Wi-Fi and fail this test. Common mistake customers are making in the field when deploying the “No Radio” models is that they do not hook an antenna up or they use the wrong one.

This chapter describes how to troubleshoot the SPS985 smart antenna at the hardware level rather then a user setup level. When solving what may be considered a user setup or field configuration issue sometimes it is good to refer to the SPS985 Quick Start Guide or perform a word search on Trimble Knowledge Network (TKN).

Service providers should determine which model the receiver is configured as and which additional options may have been purchased and added later as shown in Receiver level part numbers, page 20. In some cases this may affect the performance or which user features are seen on the unit under test (UUT). On receivers that are operational but appear that they will need to be repaired it is best practice to

Poor Radio performance Check General setup, page 135 for common setup issues.

Poor distance performance Make sure customer setup is correct for the type of survey the customer is trying to run. Find out if both the Base and Rover are set to the same wireless bandwidth of either 25KHz or 12.5KHz. Mixed settings can reduce the distance capability between the receivers. Equivalent usage of TX Frequency at 12.5KHz vs. 25KHz may need to be learned by the customer. See What narrow banding means to the service provider, page 149.

B Tip – “No Radio” models do not have a Bluetooth/Wi-Fi RF cable installed in them. However they do have specific installation instructions that must be followed. For full details jump to Terminating the TNC RF cable’s MMCX end into the upper housing, page 84.

1. Make sure O-ring is installed on MMCX RF connector.

2. From the underside channel in the upper housing found near the power supply board:

– Align the flat side of the MMCX connector with the flat side of the hole.

– Insert the connector through the hole in the housing and hold in place see Figure 6.39, page 83.

Figure 6.39 Bluetooth MMCX connector waiting for flat washer, lock washer and jam nut.


Chapter 6


3. From the top side of the upper housing:

– Place the flat washer over the MMCX connector

– Place the lock washer over the MMCX connector

– Hand tighten the 1/4” jam nut so it stays in place on the MMCX connector.

4. Using the 1/4” drive on the torque wrench itself, or a 1/4” bit, set the torque wrench to 6 in-lb, tighten the jam nut until the torque wrench clicks.

5. Torque the jam nut a second time.

Terminating the TNC RF cable’s MMCX end into the upper housing

B Tip – At this point in the reassembly process the TNC RF cables (82115-00S, 82115-60S, 82115-90S) should already be previously installed (if needed see Reinstalling the radio RF cable, page 70) and the MMCX ends are now waiting to be plugged into the upper housing. If you are repairing a “No Radio” model then skip this section and follow the instructions at “No Radio” models only:, page 84.

UHF and 900MHz models only:

1. Find the 82115-60S or 82115-90S TNC cables right angle MMCX connector and plug it into the UHF or 900MHz radio module, respectively.

Figure 6.40 Plug the right angled MMCX from the TNC connector into the radio module.

2. Now you can skip the rest of this section and jump to Plugging in the remaining cables - securing with tie-wraps, page 87

“No Radio” models only:

On “No Radio” models of the SPS985, it means there is no internal Bluetooth/Wi-Fi antenna (P/N 81078-01S) and associated Wi-Fi RF cable mounted inside the receiver under the white radome at the side of the unit. There is also no radio module mounted inside the unit.


Chapter 6


On “With Radio” models there is an internal Bluetooth/Wi-Fi antenna (P/N 81078-01S) mounted under the white radome along with a Wi-Fi RF cable that is routed from the 81078-01S board itself, over to the bottom of the top housing where the digital board plugs into it via J92 when the digital board is mounted into the upper housing. Also on “With Radio” models, the external TNC connector found at the bottom of receiver plugs straight into the internal UHF or 900MHz radio module for TX/RX operations.

On the “No Radio” models, the TNC connector found at the bottom of the receiver is routed internally so that it:

– Is mounted into the upper housing hole that the internal Wi-Fi RF cable is normally mounted to.

– This allows the external TNC connector to have a direct connection into the Wi-Fi circuit on the digital board via J92, just like the internal Bluetooth Wi-Fi board and associated internal RF cable normally achieve on “with radio” models.

This means that in order to use Wi-Fi on “No Radio” models an external antenna must be hooked up to the TNC connector on the lower housing.

From a service standpoint, during re-assembly this means that the 82115-00S RF cable has a MMCX bulkhead connector so it can be mounted onto the upper housing, rather then a right angled MMCX connector that plugs into a radio module. To mount 82115-00S into the upper housing, proceed as follows:

1. Make sure O-ring is installed on MMCX RF connector.

2. From the underside channel in the upper housing found near the power supply board:

– Align the flat side of the MMCX connector with the flat side of the hole.

– Insert the connector through the hole in the housing and hold in place see Figure 6.41, page 86.


Chapter 6


Figure 6.41 82115-00S MMCX bulkhead connector waiting for flat washer, lock washer and jam nut.

3. From the top side of the upper housing:

– Place the flat washer over the MMCX connector

– Place the lock washer over the MMCX connector

– Hand tighten the 1/4” jam nut so it stays in place on the MMCX connector.

4. Using the 1/4” drive on the torque wrench itself, or a 1/4” bit, set the torque wrench to 6 in-lb (67.79 N-cm), tighten the jam nut until the torque wrench clicks.

5. Torque the jam nut a second time.


Chapter 6


Plugging in the remaining cables - securing with tie-wraps

Figure 6.42 Photo of an upper and lower housing attached together.

1. Plug the Lemo power connector into the power supply board, see Figure 6.42, page 87.

2. Plug the keyboard connector into J2 on the power supply board, see Figure 6.42, page 87.

3. Plug the battery enclosure power cable into the power supply board, see Figure 6.42, page 87.

4. Add tie wraps as shown in Figure 6.42, page 87 in the numerical order listed below:

– Tie-wrap #1: Use to secure both the Radio and Bluetooth RF cables, as well as tie-wrap #2. Leave enough room and insert tie-wrap #2 before completely tightening the pull lock.

– Tie-wrap #2: Loop this through tie-wrap #1 and then around the Lemo power ribbon cable. Tighten loosely with the pull lock as shown.

– Tie-wrap #3: Use to secure the Radio and Bluetooth RF cables.

B Tip – Tie-wrap #2: Is there to prevent the ribbon cable from getting pinched between the lower and upper housing during reassembly and is not pulled all the way tight.


Chapter 6


Joining the upper and lower housings

Before fastening the upper and lower housings together there is a black plastic radio RF cable guide that needs to be installed on models that have a radio and it is held in place by one of the corner mounting studs. This mounting stud must be installed first as per the below assembly sequence.

1. Make sure the lower to upper housing perimeter gasket is installed before proceeding see Figure 6.42, page 87.

2. Determine which direction the bracket needs to be installed into the top housing, see Figure 6.43:

– UHF Radio Modules: The edge with the rounded “Bump” should be against the RF cable.

– 900MHz Radio Modules: The “Flat” edge of the guide should be against the RF cable.

Figure 6.43 This shows the guide bracket with the UHF “Bump” side against the RF cable.

3. Find the mounting hole in the corner near the radio module:

– Slide the mounting stud through the top side of the upper housing

– Hold in place with your finger.

4. Slide the proper side of the guide bracket onto the mounting stud.


Chapter 6


B Tip – Figure 6.44, page 89 shows how the guide bracket lands in place as the two housings are aligned.

Figure 6.44 In this example guide bracket is aligned to support a 900MHz radio module.

5. Align the upper and lower housings, push together and hold them in place.

6. Use a 1/4” torque bit tighten the first stud lightly until it is snug.

7. Insert the other 3 studs and tighten in a star pattern until they are snug. See Figure 6.45, page 90.


Chapter 6


Figure 6.45 Both the internal RF jam nut and the 4 housing mounting studs us 1/4” hex.

8. Using the 1/4” bit on a torque wrench set to 20 in-pounds (225.97 N-cm), using a star pattern, tighten each of the 4 studs until the torque wrench clicks.

9. Wait two minutes and tighten each stud a second time in a star pattern.

C Warning – Joining the housings is a critical part of this assembly procedure. Be sure to wait a full two minutes and then re-torque the 4 mounting studs a second time. This allows enough time for a phenomenon known as “mechanical release” to take place on heavily loaded screws. Where after sitting for a few minutes, there is a small relief of the fastener, requiring a second round of torquing to get them back up to the torque that is specified.


Chapter 6


Reinstalling the digital board (P/N 80090-00S)

1. Joining the upper and lower housings, page 88.

2. Install the pull tab shield into the top housing.

B Tip – Make sure the RF jack cutout completely clears the RF jack itself. Earlier versions of the pull tab shield were cut too narrow and would prevent the digital board from completely plugging into the RF jack, causing a “No Bluetooth” error. Cut material away and enlarge slightly as needed.

Figure 6.46 Align/install the pull tab shield as shown here.


Chapter 6


Figure 6.47 Digital board mounted, RF jacks in place and gasket installed

3. Align the mounting holes with the holes in the upper housing:

– Make sure the two corner guide posts are also aligned.

– Firmly plug in the 58-pin connector into the power supply board and push the board completely down.

– Make sure the two guide posts have completely passed through the digital board and the entire board is flush with the upper housing.

– Make sure the plastic pull tab piece can be jiggled back and forth and move. If it stays firmly still it may be pinched between the RF jack and digital board.

4. Using a T10 torx bit on a torque wrench set to 5.5 in-lb (62.14 N-CM), tighten each of the 10 screws (P/N 50745-00S) in the star pattern shown above until the torque wrench clicks.

5. Tighten the 10 screws a second time.

6. Place EMI gasket in place as shown in Figure 6.47, page 92.

7. Insert the two RF connector jacks, J90 and J91, into the digital board.

Reinstalling the antenna element

B Tip – The SPS985 smart antenna has two different internal antenna element service part numbers. These are based on the region where they will be sold and operated and specified by the product part number placed on the outside of the unit. All part numbers ending in “-x5” have an antenna element that is tuned for USA/OmniStar. All part numbers ending in -x0 have been tuned for use in the Rest Of World (ROW). Placing the chassis in the base mount to install the antenna element and then the radome makes reassembly easier.

6. Make sure the two RF jacks are aligned.

7. Push the antenna element firmly in place and hold as needed

8. Insert each of the 8 screws in a star pattern and use a T10 torx bit to tighten them until they are snug.

9. Using a T10 torx bit on a torque wrench set to 5.5 in-lb (62.14 N-cm), tighten each of the 8 screws (P/N 52375-00S) clock wise in the star pattern shown above until the torque wrench clicks.

10. Retighten the 8 screws a second time.

Reinstalling the radome

To re-install the radome perform the following steps:

1. Place the SPS985 into the base mount tool.

2. Make sure the radome O-ring is installed on the radome.

3. Align the notch in the radome with the notch in the upper housing and insert the radome onto the top housing.


Chapter 6

Chapter 6


7. Torque the hex screws a second time.

B Tip – If you cannot find a 1.5mm allen or hex bit that can be attached to a 1/4” torque driver you can use a hand tool. When using a hand tool keep in mind that the torque spec is 3.5 in-lb. If you fasten the dog ears gently until they feel seated then the torque spec has been met.

Figure 6.53 Fastening the two allen screws (dog ears) into the radome:

8. Refasten any dust caps that were removed with the cable set screws that they were installed with.

– Using a T10 torx bit on a torque wrench set to 5.5 in-lb (62.14 N-cm), tighten each screw clock-wise until the torque wrench clicks.

9. Retighten the each screw a second time.

Physical inspectionTo perform a physical inspection check for the following things:

• Cracked radome, top or bottom housing.

• Damaged pins or threads on the Lemo connector.

• Damaged TNC connectors, missing dust covers.

• Signs of water damage externally and/or internally, if so, do not power UUT up.

• Shake unit and listen for anything loose inside, if there is, do not power UUT up.

• Note whether there are missing or damaged S/N and/or P/N labels.

If the UUT passes all of the inspections above it has passed the physical inspection. If the UUT has not passed all of these tests make a note of which ones failed and repair them as needed when and if repairs are performed.

Seal integrity testFor a complete description on setting up the Seal Integrity Test, see Seal Integrity Test, page 165.This section assumes the kit itself is assembled and ready to use.

The Seal Integrity Test should be used as:

• Pre-Repair Qualification Test: This is a required test to see if the UUT is sealed properly before starting a repair. If a UUT fails a pre-repair test, it should be determined whether moisture could be inside and if it is then do not power the unit up.

• Post-Repair Qualification Test: A seal integrity test is always required as part of the final test procedure. Make sure the UUT passes this test and that any failures in the pre-repair seal integrity test have been fixed.

To perform a seal integrity test refer to Seal Integrity Test, page 71

As per the test, if the receiver remains sealed at -5 psi each for 30 seconds or longer without losing more then 1.0 cc of air, it has passed this test.

Run SPS985 900MHz or 450MHz radio as a Base or Rover, or both depending on UUT’s configuration. Should pass at specified attenuation setting.



Chapter 8


Retrieve/reprogram receiver configurationBefore starting a repair it is best practice to save or print out the UUT’s current configuration options so a permanent record of the original settings and TX channel frequency table are saved for future reference and re-configuration after repair. Use the interface cable 80751and Winflash as per section Verify receiver options, page 167, which is shown again here:

To view the receiver options:

1. From the Operations Selection screen, select Verify Receiver Options and then click Next. Click Finish. The Device Configuration screen appears:

2. Click Print to print a copy of the customers options.

Click OK and Menu to return to the Operations Selection screen.

Performance verification tests

Preparing to Run the Tests

To run voltage and current tests efficiently it is recommend that a variable power supply is used with the following minimum specifications:

• Min/Max Voltage Range: 0 - 40V DC or higher.

• Minimum Current: 3A or higher


Chapter 8


• Digital Display for both voltage and current readings.

A radio voltage test/interface cable with a power input is also required to perform these tests. There are two simple ways to add a power input to the standard SPS985 Interface cable (80751):

• See Voltage Test Cable, page 199. If you already have this cable from a previous service program just plug the DC power jack from this test cable into the DC power jack on the SPS985 interface cable. OR

• Modify the SPS985 Interface cable (80751):

– Snip the DC power jack off with clippers

– Strip back about 2 inches (5.08 cm) of black cable housing off to expose the positive and negative power cables found inside the cable assembly.

– Strip about 3/8” (.953 cm) housing off of both the red and black leads to expose the twisted center conductor cables.

– Tin the leads of both the red and black center conductor cables.

– If the internal cables are a different color then red and black, use a multi-meter to trace pins 1 (GND) and 6 (PWR).

– Attach stackable banana jacks: Red (PWR) to the red cable and Black (GND) to the black cable.

Once the test cable has been built prepare it for testing by doing the following:

• With the variable power supply turned off, plug the black banana jack into the ground terminal of the variable power supply.

• Plug the red banana jack into the positive terminal of the variable power supply.

• Without plugging in the test cable to the UUT, turn on the variable power supply and set the voltage to 12VDC. If the variable power supply has a current limit setting make sure it is set to 3A or higher.

• Now set the power supply to standby or turn the power off until you begin running tests. From this point forward as we describe the following tests, we will assume the power supply is set at 12V DC, 3A or higher and in standby mode at the beginning of each test unless specified otherwise.

Running the Tests

Voltage Input vs. Current Draw

The purpose of this test is to measure the current draw of the UUT when it is powered up at standard GCS system voltages. If the current draw is within specification then the UUT has passed these tests. To perform these tests follow these steps:


Chapter 8


Current Draw at 12VDC:

1. Plug the lemo cable into the SPS985 (UUT).

2. Turn the power supply on. If the current jumps like there’s a short then shut the power supply off immediately. Otherwise proceed to the next step.

3. At 12VDC the current should be:

– 900MHz and 450MHz models: About 235ma +/- 20ma to pass this test

– No Radio models: TBD...Similar to above.

4. Place the power supply back to standby mode or shut it off.

B Tip – These voltage/current tests are performed when the UUT has the battery LED lit solid and the Wi-Fi and Satellite LED’s at a slow flash (receiving signal). Any other variation or status of the UUT besides this, such as fast blink or RX or TX going, will cause the UUT’s measurements to vary.

Current Draw at 24VDC:

1. With the Lemo connector unplugged from the UUT, set 24VDC out on the variable power supply. Plug the Lemo connector back in.

2. Turn the power supply on. If the current jumps like there’s a short then shut the power supply off immediately. Otherwise proceed.

– 900MHZ and 450MHz models: About 125mA +/- 20mA to pass this test.

– No Radio models: TBD...Similar to above.

3. For easy transition to the next test keep the variable power supply “on” and at 24VDC and proceed to the next test.

B Tip – These voltage/current tests are performed when the UUT has the battery LED lit solid and the Wi-Fi and Satellite LED’s at a slow flash (receiving signal). Any other variation or status of the UUT besides this, such as fast blinking LED’s or having RX or TX going, will cause the UUT’s measurements to vary and are conditions that should be alleviated before running these tests.

Over-voltage Test

The purpose of this test is to ensure that the over-voltage protection circuit works on the UUT and whether it recovers after the overvoltage source is lowered down to within the normal input voltage range of 12-24VDC.

To test the over-voltage protection on all SPS radio models perform the following steps:


Chapter 8


1. Turn the variable power supply voltage up to 31VDC. Slowly continue increasing the voltage and observe the following:

– The overvoltage protection circuit should kick in somewhere between 31.5 and 32.5VDC.

2. Now slowly lower the variable power supply voltage back down toward 31VDC.

– The overvoltage protection circuit should turn off and the unit should power up again somewhere between 32.4VDC and 29VDC.

3. If the UUT’s overprotection circuit kicks in within the specified voltage range above and recovers after the input voltage is lowered back within normal input voltage range then the UUT has passed this test.

4. If overvoltage protection never kicks in or the UUT shorts out then turn off the variable powers supply immediately. The UUT has failed this test and the power supply board and/or front I/O panel should be troubleshot further.


Chapter 8


External power to internal battery switch test

The UUT should be able to switch between power at Port-1 and an internal battery as its power source. This test will prove that this function is still working.

B Tip – The test cables banana jacks should be plugged into the variable power supply, the USB port of interface cable (P/N 80751) should be plugged into the test computer and the Lemo connector should be plugged into the UUT. There should also be a fully charged battery (P/N 92600-HH or P/N 54344-HH) placed in the battery compartment but do not lock the battery door closed yet.

1. Log into the UUT’s web-server as per Using the Web-Server interface, page 184 and go to the \Receiver-Status\Activity screen.

2. Dial in 12VDC at the variable power supply and power up the UUT without the battery compartment closed. You should see input power listed at just Port-1 on the Receiver-Status\Activity screen as shown in Figure 8.1, page 118

Figure 8.1 Only Port-1 is showing an input voltage.

3. With a fully charged battery installed in the battery compartment, lock the battery door closed on the UUT and observe that both Port 1 and Battery 1 are now reporting a voltage as shown in Figure 8.2, page 119.


Chapter 8


Figure 8.2 Power from both Port 1 and Battery1.

4. Now dial the variable power supply down to zero volts and observe that Battery 1 is being reported as the power source on the Receiver-Status\Activity screen and both the UUT stays powered up and the web-server interface is still established on the test computer, as show in Figure 8.3, page 120.


Chapter 8


Figure 8.3 Battery 1 as the main power source.

5. If Battery 1 is reported as the main power source and you are still interfaced with the test computer then proceed to Step 6.

• If Battery 1 does not become listed as the main source and you loose the web-server interface the UUT has failed this test. Check the following in the order shown.

– Battery door was closed properly.

– Battery was inserted in the compartment and fully charged.

– Battery contacts on the battery drawer are clean and installed properly, see Battery Drawer Kit (P/N 81255-00S): Comes pre-assembled with:, page 73.

– The battery enclosures power cable is plugged into the digital board see Plugging in the remaining cables - securing with tie-wraps, page 87.

– The battery enclosures power cable terminals are installed with the proper polarity and torqued to spec as per Figure •, page 73.

6. Turn the variable power supply back up to 12VDC or higher and observe that

– Both Port 1 and Battery 1 are now reporting a voltage as previously shown in Figure 8.2, page 119 and Power 1 is listed as the main source.

– If both Power 1 and Battery 1 are listed as power sources then the UUT has passed this test.


Chapter 8


Low power test

The low power indicator (Battery LED) flashes when the power source gets down to about 15%. As long as the input stays at this level, the low power indicator will remain flashing and the receiver will stay on.

When the power source goes down between 8% and 5% the low power indicator will still be flashing rapidly and the receiver will power itself down. This test will verify that the low power detection circuit is functioning properly.

Additional Test Setup

Even if a power supply with a digital display is used, this test must be run using the web-servers \Receiver-Status\Activity screen. There can be a .20 to .30VDC difference between the voltage seen at the digital power supply versus the voltage being detected and reported on the activity screen. This is caused by various factors including the power test cable used (and its length), slight variations in the tolerances of board level components as well as the ambient temperature at the workbench where the test is being run. The activity screen reports the percentage of input power reaching the unit and this is what we will be using when running this test.

B Tip – The test cables banana jacks should be plugged into the variable power supply, the USB port of interface cable (P/N 80751) should be plugged into the test computer and the Lemo connector should be plugged into the UUT.

1. Log into the UUT’s web-server as per Using the Web-Server interface, page 184 and go to the \Receiver-Status\Activity screen.

2. Starting at 12VDC on the variable power supply and the UUT powered up, slowly turn the variable power supply downward until you observe that Port-1 power is reported as somewhere at 15% (or just under it at around 14% or 13%) on the Receiver-Status\Activity page as shown in Figure 8.4, page 122:


Chapter 8


Figure 8.4 Power input at 13%, Battery LED should flash rapidly but UUT should stay on.

– The Battery LED begins to flash rapidly to indicate low power.

– The UUT should still remain on when at or near 15% power.

Note – We took 3 good test units and averaged out the voltage between 13% and 15% to be around 11.19VDC +/- 0.07 VDC. The important thing to look for is that the Battery LED indicates low power by flashing rapidly but the UUT remains on.

3. Now turn the variable power supply down very slowly to reach somewhere between 8% and 5% of input power as shown on the Receiver-Status/Activity page per Figure 8.5, page 123.


Chapter 8


Figure 8.5 UUT dialed down to 6% of power input. UUT should shut off in 5 -10 seconds.

– Once the UUT’s input power has been set between 8% and 5% it should shut down in approximately 4 to 10 seconds.

Note – We took 3 good test units and averaged out the voltage between 5% and 8% to be around 10.95VDC +/- 0.07 VDC. The important thing to look for is that the Battery LED still indicates low power and the UUT shuts down by itself. Do not turn the variable power supply too low so that it instantly forces the receiver to shut off, the UUT should initiate its own power down.

4. Once the UUT shuts down, turn the variable power supply input voltage back down to zero and wait a couple of seconds (this simulates unplugging the power cable). Then turn it back up to 12.0VDC or higher and observe that the UUT powers up somewhere around 9.30VDC +/_ 0.07VDC as you are dialing up to 12VDC.

B Tip – Once the UUT shuts down completely you will loose the web-server interface on the test computer. This is normal and you do not need to login back into it for the remainder of this test.

5. The UUT should now power up and operate like normal. If the UUT can remain indicating low power at around 15%, initiates its own power down at around 8% or slightly lower and then powers back up, it has passed this test.


Chapter 8


Internal Antenna voltage test (optional)

The SPS985 smart antenna uses a built in antenna element with its own radome and so it does not have an external antenna jack that can be used to measure the output voltage going to an external antenna. However the digital board does feed a voltage up to the antenna element to power it up via the J90 MMCX RF extender. This an optional test that can be performed when the UUT is partially disassembled.


2. Removing the antenna element, page 48, Keep the metal shield in place.

3. Turn on the UUT.

4. Use a voltmeter set to measure DC voltage:

– Place the red (positive) test lead on the center conductor of the J90.

– Place the black (negative) test lead on the outer connector of J90 or even just on the shield or internal metal housing itself, see Figure 8.6, page 124.

Figure 8.6 Measuring the internal antenna element voltage at J90:

5. If the voltage reads 3.3 to 3.7 VDC the output voltage is correct and the digital board has passed this test.

6. If there is no output voltage the digital board must be replaced.

C Caution – Be careful not to short the center conductor of J90 to ground or inductor L702 may be damaged.


Chapter 8


Front panel LED test

The purpose of this test is to ensure that the LEDS on the front panel are working properly. Chances are that you’ve seen all of them working except for the radio LED as you have run through this battery of tests so far. The radio LED will not light up unless a RX or TX event takes place so it will light up. To check the keypad LED’s simply observe that they All light up when you first power up the UUT.

Lemo to USB port test

This test proves that the Lemo to USB interface port (Port 1) is working.

1. Plug the Lemo connector of interface cable 80751 into the Lemo port of the UUT.

2. Plug the USB cable into an available USB port on the test computer and power up the UUT.

3. Activate the WinFlash utility and select whichever COM port is being reported as COM# - Trimble USB (Example: COM9 - Trimble USB).

4. Select Verify GPS Software Version. If the software version screen appears in the WinFlash utility, Port 1 has passed this test.

Figure 8.7 GPS firmware version.


Chapter 8


Wi-Fi test

This test proves that the Wi-Fi interface is working. There must be an active wireless Wi-Fi network in the shop to runt this test. The UUT must be powered up and fully activated as a product before running this test. Simply establish a connection as per Connecting to the Web-Server interface, page 33. The same instructions are reproduced here:

1. The UUT must at least be powered up and running and fully activated as a product before trying to interface with Wi-Fi. It does not matter whether the Lemo to USB test cable P/N 80751 is hooked up to the test computer.


– Once the UUT is powered up, press and hold down the power key for at least 15seconds.









Chapter 8




B Tip – If the UUT does not appear on the available device list click to enter in and out of the list a couple of times and then see if it appears as a selection.








Chapter 8


– If the UUT’s Web-Server does not come up or a different receiver comes up then proceed to Step 7.





8. Open a web browser on the test computer and type in the IP address listed as Default Gateway as shown below in the address bar and then hit Enter, see Figure 8.11



Chapter 8


9. If you can establish a connection to the web-server then the UUT has passed this test.

Note – The 802.11 B/G white paper distance specification for “line of sight” range outdoors can be up to nearly 1000 Feet (300 Meters) in best case scenario. However this range is usually shortened by buildings, trees, radio noise interference and other obstacles. When using Wi-Fi indoors in an office environment performance to can be even worse. Due to too many uncontrollable variables we are not introducing a distance specification for this test at this time. If your shop router is 20 to 30 feet away it is expected that the UUT will perform similarly to any other Wi-Fi device that is detected on your wireless network.

BlueTooth test

Basic connection test

This test verifies that the Bluetooth module in the receiver can communicate with another Bluetooth device. The easiest way to do this is to check whether a Trimble TSC2® controller or other Bluetooth capable device can detect the receiver. To test Bluetooth communications using a TSC2 controller perform the following steps:

1. In the web-server of the UUT, select Bluetooth /Configuration.

2. Make sure that Discoverable is set to True and then click OK.

3. On the TSC2 controller, tap Start / Settings / Connections and then tap the Bluetooth icon.

4. Make sure that the Turn on Bluetooth check box is selected and then tap OK.

5. Tap Connections and then tap Add a new modem connection.

6. Select the following:

– Enter a Name For Connection: you can keep the default (My Connection) or change it.

– From the Modem drop-down list, select Bluetooth.

– Tap Next.

7. Tap New Partnership. The controller searches for Bluetooth devices.

8. If the UUT is listed as one of the discovered Bluetooth devices, it has passed the test.


Chapter 8


Bluetooth CMR test (optional)

This test will pass CMR information between two receivers using Bluetooth wireless technology. It provides a more robust test then the basic interface because it proves that some genuine data can be passed using Bluetooth. You must have two Bluetooth-capable receivers set up as “discoverable” with the web interface enabled, and tracking GPS to perform this test:

1. Enter the IP address of the unit that will be sending the CMR packets (in this example we’re using an SPS852) into the web interface.

2. Select Bluetooth / Remotes and then click Perform Inquiry. This will detect other Bluetooth-enabled receivers, in this example Device-3 is the UUT (SPS985).

3. Once Device-e is detected, click Update. A drop-down list of Bluetooth COM ports appears as shown in Figure 8.12, page 130.

Figure 8.12 Bluetooth device inquiry screen showing the MS985 as Device-3.


Chapter 8


4. From the drop-down list, select the COM port and Bluetooth Port number and then click Connect. Once the connection is established, it appears at the bottom of the screen in the Number of Remote Devices section as shown in Figure 8.13, page 131:

Figure 8.13 Select the COM port and Interface of the UUT.

5. Continuing with Device-3, select I/O Configuration / Port Configuration /Bluetooth 1.

6. Make sure that CMR is selected next to Bluetooth 1 as shown inFigure 8.14, page 131:

Figure 8.14 CMR Out select on the SPS852.


Chapter 8


– In the CMR section, select CMR or CMR+ and then click OK.

7. Now go to a new tab on the web-browser of the test computer and type the IP address of UUT (SP985, gnss or 192.168.142.1) to establish an interface.

8. Select I/O Configuration / Summary.

Figure 8.15 The UUT should show that it is receiving CMR’s under the INPUT column.

9. If Bluetooth-1 is green and shows CMR under the Input column then the UUT has passed this test.

10. Reverse the role of the UUT so that it sends CMR data to a gold unit. If the UUT can successfully send and receive CMR’s, it has passed this test.

Compare S/N and P/N to Housing Labels

To be comprehensive during performance verification it is best practice to compare the part number (P/N) and serial number (S/N) programmed inside the UUT with the external labels listed on the outside of its housing to make sure that they match each other as well as the SWO or RMA that is being repaired. To do this simply use Winflash to run Diagnostics as per Retrieve/reprogram receiver configuration, page 114 or the web-server as per Connecting to the Web-Server interface, page 33and check the following:

1. Check that the P/N matches the part number label on the housing and the SWO.

2. Check that the S/N matches the one on the housing and the SWO.

3. Check that all of the customers options and TX radio frequencies have been reprogrammed into the UUT as needed if they were wiped out during repair.

4. If all of these match then the UUT has passed this test.

5. If the P/N or S/N does not match the housing or if the UUT does not match the SWO or RMA then determine:

– If you programmed the UUT incorrectly.

– OR did a SWO get mis-matched with the incorrect UUT?


Chapter 8


GNSS signal tests The Global Navigation Satellite System (GNSS) consists of global satellite constellations managed by the following world governments:

This section explains how to check whether the different GNSS signals are being received and processed correctly by the UUT. Keep in mind that basic activation of these model numbers vs. any additional options that have been activated as an additional purchase will affect which signals show up during performance verification. See which signals are enable during standard activation in Figure 3.1, page 21.

When the customer purchases a unit, the dealer basic activation which only includes L1/L2C satellite signal sources. Others are only activated if they were options that have been paid for and activated as a separate purchase.

After a digital board swap the UUT must be reconfigured to match all of the customers options which they may have purchased. A summary of the standard GNSS signals vs. ones that are option code upgrades are shown here:

• SPS985- After Basic Activation: L1/L2C only

• Upgrades purchased after activation: GLONASS, L5, GOIVE, OmniStar-HP

Testing the satellite signal levels

This test will allow the service provider to gauge whether the satellites signal to noise ratios (SNR’s) are being received and processed at proper levels. Service providers will have to provide a live GNSS signal set by:

• Taking the unit outside.

• Being indoors where “live” GNSS signal can be received.

GNSS System Controlled By Status

GPS (Global Positioning System) Unites States – L1/L2/L2C – Currently active

– L5 – Up to three satellites may be visible for testing purposes when SBAS is enabled on the UUT.

GLONASS (Global Orbiting Navigation Satellite System)

Russia Active

Galileo/GOIVE European Union First constellation is scheduled for 2014 release. Cannot be tested at this time. You may see a test satellite appear on the satellite tracking screen, but this cannot be relied on and should be ignored.

OmniStar Satellite Subscription Service

SV MSWN should show up even without a subscription in areas where OmniStar is available on Omnistar capable units.


Chapter 8


• You should have a location where unobstructed GNSS signal can be received and have established the proper ballpark SNR’s that are normally seen at your test location.

To run this test perform the following steps:

1. Connect to the web-server and then go to the Satellites\Tracking (Table) as shown inFigure 8.16, page 134

Figure 8.16 Satellite Tracking (Table) for a receiver that has the GLONASS option installed:

– This is a general SNR test and there will be some differences when comparing to another SPS985.

– Typically there can be a 1 or 2 dB difference when comparing the exact same SV’s between two units but overall, the majority of the SV SNR’s should be close to what is expected at your test location.

– GPS L1/L2, GLONASS, SBAS and one OmniStar satellites are all being tracked in the screen-snap above.

2. If the SNR’s are showing a proper signal strength for your test location then the UUT has passed this test.


Chapter 8


Radio throughput testRunning a radio throughput test is required as part of the final performance verification test. The general setup of the test kit (P/N 65306-00s) and theory of operation are covered in the Radio Throughput Test Service Manual (P/N 65306-SVC) The following test procedures provide examples using SPS985 900MHz (82500-95) and 450MHz (P/N 82500-65) models along with a Pacific Crest TDL450L (P/N 64450-65). The test sequence itself demonstrates SPS985 specific setup and presumes that the test technician has already setup and is familiar with running the Radio Throughput Test Kit. Other model receivers can be used besides a TDL450L as long as they are listed on the radio throughput attenuation table.

General setup

Basic settings that must be followed regardless of the model of radio are:

3. Network Channel or Frequency: The TX and RX both must be set to the same net-work channel or frequency in order to be able to communicate with each other. For Example:

– 900MHz Base and Rover: Setup both for the same network ID. For instance set both up to be on Network 21. See Configure Radio Settings – Service , page 180

– UHF Base and Rover: Setup both for the same frequency. For instance set both to be 450.00MHz. See Configure Radio Settings, page 177

4. The TX and RX must be set to the same communication protocol. This is found in either in Winflash, the Web server or TDLCONF for PCC radios.

5. The TX must be tracking a minimum of 5 GPS satellites if using Live Sky, otherwise fake CMR corrections may be used. We recommend performing the test at a workbench using Fake CMR packets so it provides a true throughput test of the hardware without depending on external requirements such as the number of satellites received.

6. The TX must be sending out CMR packets to the RX.

900MHz Throughput test

Test Setup 900MHz: SPS851 Base + SPS985 Rover

This test demonstration uses an SPS851 900MHz GNSS Receiver at .5w (P/N 68805-90-XX, Firmware v4.62) as the Base and an SPS985 900MHZ radio (P/N 82500-95, Firmware v4.62) as the Rover. Before starting the test make sure the Radio Throughput Test Kit Model II (P/N 65306-00S) is setup and ready to use, including selection of proper TNC (M) to N (F) adaptor - standard or reverse polarity...depending on radio frequency being tested. This example demonstrates the Transmitter and Rover


Chapter 8


are located inside the repair shop and does not use live Sky. Rover to Transmitter separation should be at least 1.5 meters (5 feet). Alternatively, another SPS985 could be used as the transmitter (or any other 900MHz metal housing type product).

Bench setup - SPS851

SPS851 Required test cables:

• Voltage Test Cable or equivalent, see Voltage Test Cable, page 176.

• 57168: Adapter, DB26 to DB9, Ethernet and Power

• 59403: Null Modem Cable

• RJ45 Ethernet cable (to use Web-server setup)

• dB9 Serial port cable or Serial to USB adaptor cable

B Tip – Older Serial to USB port interface adaptor cables that use a Prolific brand driver and IC do not seem to interface properly to a Windows 7 -64 bit test computer. We recommend a cable with a different IC and driver such as the model XS8801 or XS8800 RS232 to USB interface cable from USCONVERTERS.com

1. Fasten the N to TNC adaptor onto the 900MHz TNC (radio) connector found on the SPS851.

C Caution – Leave the “live” GPS bench cable unplugged on the SPS85x when running the throughput test since CSG Test Suite will be generating fake CMR’s. If you have the antenna cable fastened to an SPS85x that has v4.60 or higher firmware and the “Generate Fake CMR’s” box checked at the same time a live antenna cable is plugged in, CSG Test Suite will start but then “OverLoad” may appear on the VFD of the unit and CSG Test Suite will stop receiving CMR data on the test computer. If this happens unplug the live antenna.

2. Plug the null modem cable into the DB9 connector on adaptor 57168.

3. Plug the other DB9 from the null modem cable either into a serial port cable or serial to USB adaptor.

4. Plug either the DB9 serial adaptor cable into COM1 on the test computer, or the USB end of the serial adaptor into a USB port on the test computer.

– If needed use Windows Device Manager to determine what COM # was assigned to the USB to serial adaptor.

5. Plug the Ethernet cable into the RJ45 jack on the 57168 adaptor and then plug the other end of the cable into an active network that can issue an IP address via a DHCP server.

Note – It is presumed a service provider will have an active network with available IP addresses. Setting up a network is beyond the scope of this service manual

6. Plug the DC output jack from the Voltage test cable into the DC-In plug on the 57168 adaptor.

450MHz Throughput test

Test setup - 450MHz: TDL450H Base + SPS985 Rover

This example uses a TDL450H (P/N 74450-65, FWR v3.04.2300) as the Base (TX) and an SPS985 (P/N 82500-65, FWR v4.61) as the Rover (UUT). This example demonstrates the Transmitter and Rover are located inside the repair shop and does not use live Sky. Rover to Transmitter separation should be at least 1.5 meters (5 feet). Alternatively, another SPS985 or an SPS850 (used in example 1) could be used as the transmitter (or any other UHF metal housing types).

C Caution – You MUST use the High Power Attenuator Kit when testing the TDL450H at higher than 2W RF output. Otherwise you will destroy the Radio Throughput Test Kit and damage the radios.

Bench setup of the TDL450H

TDL450H Required test cables:

• 56659-HH: Cable - TDL450 / HPB450 Programming

• 51856-00-HH: TDL 450L Power Supply

1. Connect the RF output of the TDL450 to the cable from the Variable attenuator. Make sure the 50db fixed attenuator is inserted closest to the TDL450 output. ALWAYS connect a load to any transmitter FIRST before powering up.

2. Connect the DB9 connector on the P/N 56659 cable to the COM port of your PC.

3. Connect the Lemo 1 shell 5 pin connector on the P/N 56659 cable to the Lemo port of the TDL450.

4. Connect the power connection on the P/N 56659 cable to either a battery or P/N 51856-00 AC adapter. When using the AC adapter, you will also need the SAE to DC Jack adapter. It is recommended that you build a 1 meter SAE to dual banana jack cable which will allow you to easily use a variable DC power supply. Press the power to turn on.

Note – The above interface cable and power adaptor can be purchased along with a universal power adaptor kit as sales part: 64450-11.

Configuring the TDL450H as a Base

B Tip – This demonstration will setup the TDL450H Base to use the 12.5Khz channel spacing bandwidth. To change between 25K and 12.5K bandwidth service providers must use the dealer version of TDLCONF to do this.


Chapter 8


1. Activate TDLCONF on the test computer. When a blank screen comes up click on the Connect button.

2. When the Connect to TDL Radio screen comes up select the COM port that you plugged the DB9 interface cable into on the test computer. Make sure soft break is selected as shown below and then click OK.

Figure 8.20 Select the appropriate COM port and soft break. Data rate cycles until detected.

3. The Dealer setup screen should come up as shown in Figure 8.21. Match the following settings with the UUT (Rover):

• Channel RX & TX: Make sure the frequency needed for testing is found in the Channel Table at the bottom. (In this sample we are using 464.5000).

– If it is not, enter it into both the RX and TX boxes and then click on Apply. The new frequency should now appear in the table.

• Bandwidth: Set to 12.5K (or matches Rover). In 2013 it goes to 12.5K

• Max Power: Make sure this is set to match the UUT. For instance if the UUT is a .5W product then set it for .5W. If the UUT is set for 2W then change this setting to 2W.

C Warning – Do not let the MAX TX Power setting be higher then the UUT’s power rating or damage to the UUT as well as the radio throughput test kit will occur. Do not allow the setting to be higher then 2W unless you are using the High Power Attenuation Kit.

• Link Rate: This is the baud rate of the wireless radio protocol: Radio testing will not work if the Link Rate is not matched between the Base and Rover radios. (For this demonstration use 4800).

• Mode: Manual (default).

• Modulation Type: GMSK (default).

• Sensitivity: This is a squelch setting:

– For Base (this demonstration): Low (Base).

– For a Rover: High (Rover).

• CSMA: Box should be checked (default).


Chapter 8


• TX Power Level: Make sure this is set to match the UUT. For instance if the UUT is a .5W product then set it for .5W. If the UUT is set for 2W then change this setting to 2W. (Set to 2W for this demonstration).

• Repeater: Leave blank

C Warning – Do not let the MAX TX Power setting be higher then the UUT’s power rating or damage to the UUT as well as the radio throughput test kit will occur. Do not allow the setting to be higher then 2W unless you are using the High Power Attenuation Kit.

6. Now click on the Identification tab as shown in Figure 8.24, and make the following settings:

New FCC VHF/UHF 12.5KHz Narrow banding requirement

Starting January 1st, 2013 all radio products operating within the USA in the VHF and UHF (450MHz Models Only) frequency range will have to operate with a 12.5KHz channel spacing instead of the previous 25KHz channel spacing bandwidth. By the time of this writing all of Trimble’s current radio products have been configured to leave the factory with the 12.5KHz channel spacing setting. An excerpt about the new narrow banding requirement is reproduced here from the FAQ section by the FCC (http://transition.fcc.gov/pshs/public-safety-spectrum/narrow banding-faq.html):

What is Narrow banding?

Narrow banding is an effort to ensure more efficient use of the VHF and UHF spectrum by requiring all VHF and UHF Public Safety and Industrial/Business land mobile radio (LMR) systems to migrate to at least 12.5 kHz efficiency technology by January 1, 2013.

More specifically, all existing Part 90 radio systems operating in the 150-174 MHz and 421-512 MHz bands have until January 1, 2013 to convert those systems either to a maximum bandwidth of 12.5 kHz or to a technology that provides at least one voice path per 12.5 kHz of bandwidth or equivalent efficiency.

What does Equivalent Efficiency mean?

Any of the following meet the 12.5 kHz equivalent efficiency requirement:

One voice path in a 12.5 kHz channel

Two voice paths in a 25 kHz channel

Data operations on channels greater than 12.5 KHz must employ data rates greater than 4.8 kbps per 6.25 kHz channel, such as 19.2 kbps per 25 kHz channel

What is the purpose of Narrow banding?

Currently, the majority of UHF and VHF LMR licensees operate using 25 kHz efficiency technology. However, the UHF and VHF frequency bands are congested with limited spectrum available for system expansion or implementation of new systems. The migration to 12.5 kHz efficiency technology will require licensees to operate more efficiently, either on narrower channel bandwidths or increased voice paths on existing channels. This will allow creation of additional channels within the same spectrum, thereby supporting more users.

What narrow banding means to the service provider

For authorized service providers the change to the 12.5KHZ channel spacing makes a couple of new requirements and things to be aware of:


Chapter 8


• Check whether the UUT set to 12.5KHz or 25KHz: This should be set by default to 12.5KHz on -x5 models. In some case the customer may require the 25KHz setting when outside of the Unite States. When this setting needs to be changed it must be done using WFS\Radio Config - Service. Once this has been run it is also good practice to go back to WFS a second time to run the standard WFS\Radio Config operation to double check which wireless protocol and channel frequency is set.

• Radio throughput test: Our radio test methods may be revised again in the future but for this service manual we have included wireless protocol and attenuation settings at both 25KHz and 12.5KHz channel spacing and for .5W and 2W output for the UHF radio.

• Equivalent Distance: To some degree there will be an industry wide learning curve with customers in regard to which wireless protocols at 12.5KHz will give them equal distance performance compared to the 25KHz channel spaced wireless protocols that were previously used. For instance the following 2 settings will yield similar distance performance when running a survey:

Operating the “Radio Throughput” test

B Tip – Although some minor editing was done, this section is an excerpt from the Radio Throughput Test Kit Service Manual, Rev D. Please refer to that document for the latest information. This is shown here as a courtesy but this service manual may not be updated as frequently as the Radio Throughput document and the attenuation spreadsheet.

This section outlines the basic steps required to operate the CSG Test Suite software to run a radio throughput test. Once the base and rover are setup, running the test itself is identical whether the radios are UHF or 900MHz series products.

Caution – Make sure the TX radio does not transmit more than 2 Watts or damage to the attenuators and radio’s may result.

Note – As a courtesy the attenuator settings from the Radio Throughput Attenuation spreadsheet used for the 900MHz and 450MHz demonstrations in this service manual are included here (but refer to the Radio Throughput Attenuation Table, which can be found on Partners, for the most current information):

Table 8.2 450MHz/.5W: TDL450 and SPS985 - Attenuator settings:

Table 8.3 450MHz/2W: TDL450 and SPS985 - Attenuator settings:

1. Set the appropriate attenuation settings as found in the Radio Throughput attenuation table based on the Base and Rover that you are interfacing, see Table 8.1, Table 8.2, Table 8.3.

• Example: On the variable attenuator turn the “10 dB-step” knob to 20 and then the “1 dB-step” knob to 5 (for 900MHz radio throughput test).

B Tip – This will be 125dB in total since a 50dB attenuator is placed at the end of each RF cable.

2. Double click on the CSG Test Suite (CSG) Icon to activate the test software.

3. Power up the Base if it is not powered up already.

4. On the lower tool-bar in CSG click on Open (Source)

Figure 8.29 CSG Test Suite showing synchronization with the UUT/Rover (Listener) radio:

Analyzing the test results

1. Once the link between the Base and Rover has been established, check that the following default tool-bar settings are in place:

– All: is pressed down

– Log Unknown: is pressed down

– 1HZ+: is pressed down

– + SV Button: Click the Add SV button and increase the # of SV’s to 15

2. Press the Reset button a couple of times to clear the data and see that both Count and Source start out evenly.

B Tip – On older pre-GNSS receiver and/or radio products we always used the default of 9 SV’s during this test. However modern GNSS receivers typically can use 15 SV’s. By increasing the # of SV’s used the CMR packet size becomes larger, which simulates a real life packet size more accurately then leaving this at the default setting.


Chapter 8


3. Allow the test to run for 10 minutes. As the test runs it combines the L1/L2 sent/received averages (CMR Type 0) into one overall throughput average that it displays in the upper right hand corner of the status screen. After 10 minutes check for the following result, see Figure 8.30, page 155.

4. An average of 95% or higher should be the final result after 10 minutes to pass this test. Perfect to Good should be displayed under Rating.

Figure 8.30 Analyzing test results in CSG Test Suite:

Note – Different transmitters will have different warm up characteristics. Some, like the older SiteNet radio series, may require a 10 minute warm up period before the RF output signal strength stabilizes. Typically they increase output power by 1-2 dB

B Tip – When the test is completed, in CSG-Test Suite click on the Close button for both the Source and Listener to deactivate the test.

Testing the SPS985 as the Base and the TDL450L as a Rover

Now that all of the main settings were previously set, reversing the role of the radios so that the TDL450L becomes the Rover and the SPS985 becomes the Base is easy and all associated changes can be done on the web-server of the SPS985 and from the front panel of the TDLS450L. Running a throughput test with the SPS985 as both a Base and a Rover is required for a complete performance verification test.

Setting the TDL450 to Rover Mode


Chapter 8


1. Using the keypad on the TDL450, press the right arrow until you reach the Radio Operation Mode. It should still be set to Base/Rover. If it is just keep it there. Press the right arrow key until you reach the RX Sensitivity setting. Press the down arrow key to select High (Rover). Press the O or Enter key to save.

2. Leave all other settings the same.

– Click on OK.

5. Reactivate CSG test suite starting at Step 6 on page 151:

– This time click on Source and select COM2 (the SPS985 is now the Base).

– Click on Listener and select COM1 (The TDL450 is now the Rover).

– Once the test is started unplug the MS985’s interface cable from the test computer. This is so CSG test suite will not double count the packets.

– Click on Reset in CSG Test Suite.

6. Now run the throughput test as per Analyzing the test results, page 154.

B Tip – The Radio LED on the SPS985 and the RX LED on the TDL450Lshould both light up intermittently.

7. If the SPS985 transmits successfully and the TDL450 passes at 95% after 10 minutes, both the SPS985 and TDL450 has passed this test.

B Tip – When the test is completed power down the SPS985 to stop the test. Closing the Source will not work since the interface cable was unplugged to prevent double counting.

WinFlash utilityWinflash Supervisor is the main software configuration utility provided to authorized service providers so they can perform product configuration during repairs or upgrades to Trimble products.

Winflash Supervisor itself is being migrated into Trimble’s online Performance Analysis and Service Software (PASS). If you are not provided with the Winflash Supervisor utility directly now or in the near future then it may be because it is only available through PASS. PASS itself is an online utility system designed for Trimble Service Providers. Once Winflash Supervisor has migrated to PASS, other than an a PASS login screen and an initial user interface product selection screen, the Winflash Supervisor utility screens will operate the same as the standalone version of Winflash.

Winflash Supervisor has a standard set of operations that always appear as selections on the menu screen and some operations that only appear in what is called Supervisor Mode. This chapter is divided into:

• Standard Winflash Operations

• Supervisor Only Operations

• Configuring the Radio Modules

Winflash - Supervisor Only Operations

Winflash Supervisor is different than the customer version of the Winflash utility. It provides some configuration utilities to Trimble service providers that are not available in the standard version. Therefore, Trimble prohibits distributing Winflash Supervisor to our customers. To access the supervisor mode functions:

1. Highlight a product with your mouse at the Device Configuration screen.

2. On the computer keyboard hold down CTRL and ALT and then click on Next in the Winflash utility.

The Operations Selection screen appears as normal, but lists any additional programming utilities that are not seen in regular WFS mode.

Programming the electronic serial number (ESN)

This programming utility will only allow a service provider to enter an S/N onto a new service board that has a blanked out ESN. It will not allow you to blank out or change an existing one. An S/N can only be programmed into a new board ONE TIME so it must be entered correctly on the first try. Otherwise you will need to contact Trimble technical support for further assistance. To program an S/N perform the following steps:

1. In supervisor mode, from the Operations Selection screen, highlight Program receiver serial number and click on Next. Click Finish.

The Update User Info screen appears with an empty Serial Number field:

2. Compare that the serial number on the housing of the UUT is the same as on the SWO order that you are repairing. If it is the same, enter the serial number and then click OK.

Configuring the radio modules

To configure and setup the radio modules, a combination of Winflash operations in standard and supervisor mode, the products Web-Interface and Winflash-Radio Service Provider Opt utility v1.460 will be used as needed. A summary of each operation is listed below:

Saving the Customers Frequency Table: If the UUT is operational, Trimble recommends saving the customers original frequency table if it differs from the default table entries. To check if the customer has additional frequencies added to their frequency table, review the table using Configure Radio Settings in standard Winflash Supervisor mode. This operation is the same for both the UHF and 900 MHz models. If there are additional frequency table entries, use the WinFlash radio Service Provider Opt utility, v1.460 or higher, to save the frequency table.

Wipe Radio Configuration Blocks (new in Supervisor mode for the SPSx8x series): This is used to erase the radio module settings from the main board’s memory. When this is done, the main board re-detects the radio module and will then rebuild the radio data dictionary based on the frequency band range and model of the radio module. This operation is the same for both the UHF and 900 MHz models.

(Configure Radio Settings) Frequency Selection setup screen: This is the basic radio configuration used when setting up the radio to interface with other system level radios.

• UHF: Allows Base frequency channels to be added and the selection of the Current Channel.

• 900 MHz: Allows changing the setting the Network Number, Mode, and Country Code.

(Configure Radio Settings – Service): Configure Internal Transceiver screen: This operation is similar to the functions available previously when there was a separate Radio ASP utility for old SiteNet/TC series radios, where the initial frequency band is set in Supervisor Mode and cannot be changed again in standard Winflash Supervisor. This section also allows the service provider to switch between 25KHz and 12.5KHz channel spacing on UHF models

• UHF: Allows the overall Frequency Band Range to be set, the default channel spacing and the default set of channel/frequencies. Trimble requires that this must be set to match the frequency band range specified in the Part Number of the UUT ending in -60, -62, -64 or -66. Trimble does not allow hybrid configurations. Channel spacing can be set to either 25KHz or 12.5KHz.

• 900 MHz: Allows default settings of the Network Number, Mode, and Country Code.

Note – In Supervisor Mode, if the only selection under the Mode list is Rover, it is because Base or Base/Rover combination settings are part of a subsequent upgrade option package purchased through the Partners Store. To retrieve Option key codes either log into the Partners store and look up the serial number or contact service support. UUTs that do not have a Base option activated can only be tested as a Rover.

Service SoftwareF

Web-Server Interface: Trimble recommends that customers who have data logging enabled and have data files on their receiver, save the logged data files using the Data Logging / Save File option. This is accessed by right-clicking the logged data file.

Winflash Radio Service Provider Opt utility v1.460 or higher: This utility still requires you to save the customer frequency table to *.txt file. This file can then be loaded using the load command found in v4.15 or higher of the Winflash Supervisor (Radio Configuration section).

Winflash Radio Service Provider Opt utility v1.460 or higher: This utility is still needed to save the customer frequency table to *.txt file. This file can then be loaded using the load command found in v4.15 or higher Winflash Supervisor\Radio Configuration section.

If the UUT is operational, check to see if the customer has additional frequencies added to their frequency table. To do this:

1. In Winflash Supervisor mode, go to Configure Radio Settings. If additional customer frequencies are listed under the Channel Frequency table, continue with Step 2; if the only frequencies listed are default frequencies, you do not need to save the frequency table.

2. Exit Winflash Supervisor and activate Winflash-Radio Service Provider Opt utility version 1.460 or higher and then click Create Frequency Update File, Next, and OK.

3. Enter the UUT’s S/N and then click Next.

4. The frequencies that are already programmed into the unit appear. Click Next:

6. Once the frequency file is saved, select Menu and then click Back to return to the Winflash Device Selection screen.

Wipe radio configuration memory blocks

This Winflash Supervisor function is used in conjunction with Configure Radio Settings – Service.

This function erases the current radio module settings held in memory on the Main Board and can be used on both 900 MHz and UHF models. Once the radio configuration blocks are erased, the Winflash utility restarts the receiver and rebuilds the radio data dictionary based on the radio module that it detects as plugged into the main board. After this, you must configure the radio module settings using the Configure Radio Settings – Service utility.

Use Wipe Radio Configuration Blocks to achieve the following:

• A hardware mismatch is reported when you go to activate the standard Configure Radio Settings function in the Winflash utility. The following message appears:

Note – This message may be caused by a number of issues that are not actually related to a corrupt data dictionary:


Chapter 9

Service SoftwareF

• A defective or incorrect radio module may cause this error to show.

• If the UUT is assembled with the wrong radio module this message appears. For example, the main board is configured to be a 900 MHZ model, but is reassembled with a UHF radio module.

• If a radio module has been replaced with the exact same part number of the radio module but this error message appears, this could indicate that the data dictionary is corrupt. In this case, it may be best to rebuild it using this utility rather than replacing the main board.

• Sometimes you may want to run Wipe Radio Configuration with the original radio module installed to see if everything starts working again.

Note – When the memory blocks are erased, it also erases any custom frequencies programmed into the unit. It does not erase the main board configuration settings or the serial number of the receiver. Therefore, Trimble recommends to always follow the below process below before wiping the radio memory blocks:

B Tip – First save the customer’s frequency table as needed. See Saving the customers frequency table, previous page.

Clearing the radio module configuration memory blocks

To clear the radio modules memory configurations blocks, from the Operations Selection screen in Supervisor Mode:

1. Select Wipe Radio Configuration Blocks and then click Next.

Configuring the UHF radio

The SPS985 Smart Antenna uses a fully functional “wide-band” radio module that can both receive and transmit across the entire UHF spectrum of 410 to 470 MHz.

Configuring Radio Settings - Service

1. From the Operations Selection screen, select Configure Radio Settings - Service and then click Next. Click Finish. The Configure Internal Transceiver appears:

• Frequency Band: In Supervisor mode, this field is now white so it can be edited. Use the dropdown menu to match the bandwidth that the part number of the UUT specifies:

– -60: 410-470 MHz (wideband products such as the SPS852 only).

– -62: 410-430 MHz (narrow band products such as the previous SPSx51/SPSx50 series)



C Warning – Trimble requires that all service providers configure the Frequency Band Range of our radio products to be the part number that they were sold as. The same part number listed on the radio housing and Frequency Band settings will match

between “like” products and corresponding replacement parts. When using a -60 radio module to replace a narrow band series radio module in older SPSx5x products, this setting must match the part number (-62, -64, -66) on the bottom of the receiver even though it is a wideband radio module. See the appendix in the back of this manual for installing a -60 radio module into older products.

• Channel Spacing: 25 KHz or 12.5 KHz

Note – In January, 2013 the Unites States will require all UHF radios being operated within US borders to have their channel spacing set to 12.5KHz

• Destination: Select the country code to match the region where the unit will be used:

– 1 - Rest of World

– 3 - United States/Canada

– 9 - Europe

• Specify Frequency window and the Add key: Used to insert additional frequency channels.

• Selected Frequencies: The “ok” key will remain gray until you add a set of default channel/frequencies for the selected radio band as shown below. Use the Specify Frequency screen to manually enter the default frequencies one by one. Click Add after each entry as shown below:

– -60: 410-470 MHz: 1) 410.00000, 2) 440.00000, 3) 470.00000

– -62: 410-430 MHz: 1) 410.00000, 2) 420.00000, 3) 430.00000

– -64: 430-450 MHz: 1) 430.00000, 2) 440.00000, 3) 450.00000

– -66: 450-470 MHz: 1) 450.00000, 2) 460.00000, 3) 470.00000

2. If a customer’s Radio Frequency Set file was saved reload it now.

3. Once all settings are made click on Ok to program them.

Configure Radio Settings

When swapping a “like” radio module and the radio memory has not been erased (wiped), the radio dictionary on the main board remains intact along with the customer’s original radio module settings: Frequency Band Range, Current Channel, Wireless Mode and detected properly by the main board.

To set up a “like” radio module after installing it:

1. Install the radio module. See Reinstalling the radio module, page 82

2. From the Operations Selection screen, highlight Configure Radio Settings and click Next. Click Finish. The Frequency Selection screen appears:


Chapter 9

Service SoftwareF

• Frequency Band: This setting cannot be changed in standard Winflash mode and appears unavailable. It should match the bandwidth that the part number of the UUT specifies:

– -60: 410-470 MHz (newer wide-band version products only)

– -62: 410-430 MHz

– -64: 430-450 MHz

– -66: 450-470 MHz

If the frequency band range does not match the part number on the bottom of the receiver, then go into Winflash Supervisor mode. Select Configure Radio Settings – Service and then set the frequency band range and default frequency table to match the appropriate part number.

• Current Channel: The default is Channel 1. Else, select a different channel.

B Tip – At this point, If needed, load the customers frequency table back into the UUT. See Saving the customers frequency table, page 172.

• Wireless Mode: Trimtalk 450S protocol is available with four different baud rates: 16000, 8000, 4800, and 9600 bps. Match this baud rate setting with the protocol setting of the radio being interfaced with. Default is 4800 bps.


Chapter 9

Service SoftwareF

• Radio Settings - Mode: Base or Rover drop-down menu (as shown in the screen-snap above): This section will only appear on this screen if a Base option has been purchased. If “Radio Settings” is missing on the screen then the receiver is only configured to be a Rover.

Note – It is important to check this because if the UTT should be configured as a Base station but does not list Base and Rover then further option code(s) such as Base and Rover upgrade or Base upgrade to Full RTK still need to be applied to the receiver, so that the Base station can be a selection on this menu. This is one good reason why the customers “Verify Option Codes” printout should be done (when possible) before starting a repair.

• Channel Frequency: Specify Frequency field and the Add button: Inserts additional frequency channels besides the defaults shown.

• Selected Frequencies: Used to add or remove receive frequencies. The initial set of default frequencies are created in Supervisor Mode when the radio module is first configured. Additional ones are created and added here.

• Radio Info button. Click Radio Info. The following information appears:

The new radio module has been detected if the information in this section is filled out.

3. Make sure the bandwidth of the radio module is 410-470 MHZ on -60 products. If it is set incorrectly you will need to reset it by running Configuring Radio Settings - Service, page 176

The Radio Module version may change in the future without further notice.

The Channel Spacing (25KHz or 12.5KHz) should be matched to the customers specific region or with the other radios they may be using with the UUT.

Configuring a 900 MHz radio module

After performing the “Wipe Radio Configuration Setting” operation, the radios memory configuration blocks have been erased. Upon reboot, the main board re-detects which radio module is installed on the UUT and rebuilds the radio dictionary accordingly. Configure Radio Settings – Service is used to set the final default settings of the radio module permanently on the main board. Once the settings are completed in supervisor mode, customers and dealers cannot alter these settings.

Configure Radio Settings – Service

1. From the Operations Selection screen, select Configure Radio Settings – Service and then click Next and Finish. The Configure 900MHz radio dialog appears:

• Network number: Set default to Network 1.

• Country setting: The default for this setting should be set to match the country code built into the part number on the bottom of the receiver as follows:

– -91 (US/CAN)

– -92 (Australia)

– -93 (New Zealand)

You can change this setting later using the drop-down list in Winflash standard mode, but it cannot be left blank during this configuration or it will remain blank later.

2. Click OK and then click Menu to return to the Operations dialog.

Products and their seal integrity decay rates

Note – The Protek DMM506 is no longer available in the 48848-00S Seal Integrity Test kit. It has been replaced by a Fluke 115 DMM, which does not have RS-232 capability so you cannot use it with an office computer. To do the test, read DCmV and use the Min/Max function or Relative Deviation function.

Always ensure that a unit does not leak, both when it comes in and once it has been reassembled. To check for leaks, use a Trimble Seal Integrity Test Kit (P/N 48848-00S). The kit provides a complete vacuum and pressure leak detection system that includes a digital multimeter (DMM).

• For vacuum you will see –5 mV, which equates to –5 inches of Mercury (inHg).

• For pressure you will see +5 mV, which equates to +5 inHg.

The relative deviation should, in most cases, be no more than 300 µV/100 seconds. For allowable leak rates see Products and their seal integrity decay rates, page 195.

Additional toolsIn addition to the Trimble Seal Integrity Test Kit (P/N 48848-00S), the following tools are required:

• open-end adjustable wrench

• channel locks

• pliers

Testing vacuum
C Caution – Most Trimble products are tested with vacuum only. Using pressure could damage seals within the product as they were not designed to withstand it. Under no circumstances should you allow vacuum or pressure to exceed ±5 inch Mercury (inHg).

To test vacuum:

1. Ensure that the test kit is working properly. See Vacuum testing the Seal Integrity Test Kit, page 193.

2. Once you are sure that the test kit is working properly, test the device. See Vacuum testing the device, page 193.

Vacuum testing the Seal Integrity Test Kit

Note – Turn on the PV350 at least three minutes before you run the Seal Integrity test. This allows time for the circuits to stabilize

1. The O-ring must be installed on the adaptor before you test vacuum.

2. Install the 10-32 brass nut onto the vacuum adaptor.

3. Make sure that the hand pump is in Vacuum mode. Pull the trigger while watching the voltmeter display. Do not exceed –5 mV.

4. Make sure that the PV350 is set to the cmHg/inHg setting.

5. On the PV350, adjust the Zero potentiometer until the mV reading on the DMM is as close to zero as possible.

6. Pull the hand pump trigger slightly. Check the displays. If the reading goes past –6 mV, relieve some of the vacuum until the reading is at or slightly below –5 mV.

7. Wait at least two minutes and then observe the vacuum loss over 100 seconds.

– There should be no large positive and negative fluctuations.

– There should be no appreciable vacuum loss over 100 seconds. Maximum decay rate is 300 µV (0.3 inch Mercury) over 100 seconds. Some products, such as the TSCe controller, have a decay rate of 1 inch Mercury over 5 seconds, which means that after 25 seconds they will be at atmosphere. Other products differ.

If a leak is detected, check the O-ring seal, tubing connections, and Teflon tape connections.

Vacuum testing the device

By using the brass cap on the adaptor, and the vacuum test, you have proved that the Seal Integrity Test Kit is working properly.


Appendix A

1. To test the device, connect the vacuum adaptor to the unit:
a. Remove the brass cap from the vacuum adaptor.

b. Install the adaptor into the seal port of the unit and tighten by hand.

c. If the unit has a vent hole, install a piece of Kapton tape over the vent hole to seal it.

2. If large fluctuations occur, but the average is fairly constant, change the sample rate to 1 sample for every 2 seconds. (Type in 2 seconds.) This setting will smooth the transitions.

– If results show a fairly flat line, with fluctuations of about 100 µV, wait 100 seconds. If the displayed mV changes less than 300 µV for the relative delta, the unit has passed the Seal Integrity test and is functional.

– If the displayed mV changes more than 300 µV for the relative delta after 100 seconds, the unit needs to be re-tested. Check all seals and connectors and the keypad (if applicable).

Tip – You can use this data acquisition system to monitor many things (for example, temperature, voltage, or current) over time. It is especially useful for recording AC power.

Testing pressure

C Caution – Test pressure only if you are specifically instructed to do so. Otherwise, test vacuum only. Some units will be damaged if you pressure test them!

Note – The O-ring must be installed before you test vacuum.

Note – Turn on the PV350 at least three minutes before you run the Seal Integrity test. This allows time for the circuits to stabilize.

1. Install the 10-32 brass nut onto the vacuum adaptor.

2. Make sure that the hand pump is in Pressure mode.

3. Make sure that the PV350 is set to the cmHg/inHg setting.

4. Pull the hand pump trigger slightly and then check the display. If the reading goes past +5 mV, relieve some of the vacuum until the reading is at or slightly below +5 mV.

5. Wait at least two minutes and then observe the vacuum loss over 100 seconds.

– There should be no large positive and negative fluctuations.

– There should be no appreciable vacuum loss over 100 seconds. The maximum decay rate is 300 µV (0.3 inch Mercury) over 100 seconds.

6. By using the brass cap on the adaptor and using the vacuum test, you have proven that the Seal Integrity Test Kit is working properly. If a leak is detected, check the O-ring seal, tubing connections, and Teflon tape connections.

Splitter, base, and roof-top antenna compatibility

Antenna gain

C Caution – Current FCC regulations mean that Trimble cannot endorse the use of a re-radiator in the United States, at this time. If you are in the United States, and you have a re-radiator set up at your workbench, you must contact your local authorities and/or the FCC to check if you are permitted to use it in your area.

When patching signals to your workbench for testing, both the rooftop antenna itself plus the signal splitter (if one is being used) must be able to process GNSS (GPS, GLONASS, L2C, L5) RF signals.

A GNSS splitter system is ideal for troubleshooting Trimble products at the workbench because it provides DC-blocked RF signal output to your workbench for direct GNSS series signal input to the UUT. This is referred to as Test 2 in Figure B.1 on page 198 and throughout this manual.

Trimble no longer includes information on setting up Test 1 using a re-radiator system, as explained in the Caution above. Trimble service providers who use a re-radiator do so at their own risk. Instead of a re-radiator Test 1, you can run a live test. To test the SNRs when the UUT is fully assembled do the following:

– Take the UUT outside to receive satellites and review SNR information

– Determine whether SNR’s are at proper levels in your area

“Test 1” throughout this Service Manual refers to whichever of these methods you use for live signal testing with a fully assembled Trimble unit.

Splitter, base, and roof-top antenna compatibilityTrimble recommends ordering a four-way splitter with one port set up to allow DC out (DC Pass), and with the other three ports set up to have the DC voltage blocked (DC Blocked) so that only the RF signals are allowed to pass through. For testing, use the DC Pass port to provide voltage to a GNSS antenna on the roof through a base receivers antenna output jack, and use the three DC Blocked outputs to provide DC-blocked RF input to the equipment under test at your workbench.

Make sure the four-way splitter allows broadband signals from 1 GHz to 2 GHz (including GPS, L2C, and GLONASS signals) to pass through. Currently, L5 satellites are not routinely active.

As shown in Figure B.1, the antenna voltage between the rooftop antenna, the base, and the splitter must be matched for compatibility. The rooftop antenna and base also need to be matched so that they provide the correct RF signals for testing at your work


Appendix B

GPS SplitterF

bench. If you are using a pre-GNSS series antenna and base, you must update them so that they process GLONASS, L2C, and L5, along with the usual L1 and L2 GPS signals. Typical equipment requirements are listed in the figure.

Antenna gain

Trimble recommends that you order a splitter that has 0 dB gain or that has enough gain to compensate for the RF cable loss. This ensures that there is little or no gain by the time the RF signal reaches the equipment at the bench.

If gain is boosted too high, a number of problems could arise. For example, the SV SNR readings might be unrealistic. In addition, some GPS equipment does not respond well to signal levels that are too high.

Figure C.2 Completed Radio Voltage Test Cable with Lemo to Bendix adaptor plugged in.

Using the Voltage Test CableTo use the test cable follow these steps and precautions:

Caution – Before using this radio test cable with a variable power supply make sure that the built in DC adaptor input jack on cable 59044 does not have a DC power adaptor plugged into it.

1. Plug the black banana jack into the negative connector of the variable power supply.

2. Plug the red banana jack into the positive connector of the variable power supply.

3. Depending on which Trimble radio product you intend to test and what that particular service manual instructs you to do, set the variable power supply to either 12 or 24V DC and the current limit to 3 amps or higher or as specified in the service manual.

4. Now either turn the variable power supply off or place it in standby mode. You are now ready to begin testing.
