1.1 General Furunos NavNet is the Ethernet based high-speed network. NavNet products will allow us to customize marine electronics according to users needs with simple cablings. All display units are capable of controlling any component connected to the NavNet network. NavNet series include;
1) 7-inch monochrome radar/video plotter: Model 1722/1732/1742/1752/1762 2) 7-inch color radar/video plotter: Model 1722C/1732C/1742C/1752C/1762C 3) 10-inch monochrome CRT radar/video plotter: Model 1833/1933/1943 4) 10.4-inch color LCD radar/video plotter: Model 1833C/1933C/1943C 5) 7-inch monochrome STN LCD Video plotter: GD-1700 6) 7-inch monochrome color TFT LCD Video plotter: GD-1700C 7) 10.4-inch color TFT LCD video plotter: GD-1900C 8) Network sounder: ETR-6/10N 9) GPS receiver antenna: GP-310B
The GPS receiver antenna GP-310B looks like an antenna, but it is a compact 12-channel GPS receiver.
The IF amplifier used on the NavNet series radars differs from model to model: Model 1722/1722C/1732/1732C/1742/1742C/1752/1752C/1762/1762C uses Linear IF amplifier, while Model 1833/ 833C/1933/933C/1943/1943C uses Logarithmic IF amplifier.
An Ethernet repeating hub needs to be arranged locally for a multiple display system.

1.2 About The NavNet
1-2
1.2 About The NavNet The following describes more details about NavNet. The NavNet is a baseband network that provides a single channel for communications across the physical medium (e.g., cable), so only one device can transmit at a time. An analogy is a single phone lines such as you usually have to your house: Only one person can talk at a time if more than one person wants to talk everyone has to take turns. Data travels in packets on a network. Packets are transmitted in standard Ethernet frames. The Ethernet header contains the destination and source addresses and the Ethernet type code. The data field immediately follows the header.
+- - - - - - - -+
| 6 byte | Destination Address | | +- - - - - - - -+
| 6 bytes | Source Address Header | | +- - - - - - - -+
| 2 bytes | Type field | | +- - - - - - - -+
| ?? bytes | Data | | +- - - - - - - -+
Figure 1.1 Packet The NavNet supports a 10 Mb/s transmission rate over two pairs of Category 3 shielded twisted pair (STP) cabling. The NavNet protocol is TCP/IP and the media access control mechanism used by the NavNet is CSMA/CD (Carrier Sense Multiple Access). Table 1 compares the NavNet with different physical types of Ethernet.

1.2 About The NavNet
1-3
All NavNet connections are point-to-point. This implies that a NavNet cable can have a maximum of two NavNet transceivers with one at each end of the cable. One end of the cable is typically attached to an Ethernet repeating hub or an active hub. The other end is attached directly to a NavNet product, which includes a NavNet network interface card (NIC). Two NavNet products may be directly attached to each other without a hub. In this case, a crossover cable (type: MJA6SPF0014), of which each end is terminated with a 6 position MJ connector, is used: one pair of wires is used for transmitting data, and the other pair for receiving data. When attaching a NavNet product to a repeating hub, a normal straight through cable is used and the cross over function is performed inside the repeating hub. In practically, when the NavNet is connected to the hub, a NavNet conversion cable (type: MJ-A6SRMD/TM11AP8-005) is required.
The run length of NavNet cables is limited to 30 meters. The point-to-point cable connections of the NavNet result in a star topology for the network. A star topology consists of a central hub with point-to-point links that appear to radiate out from the center like light from a star. The star topology simplifies maintenance, allows for faster troubleshooting, and isolates cable problems to a single wiring link.
(1) What is a hub? A hub is a common wiring point for star-topology networks. Hubs have multiple ports to attach the different cable runs. Hubs do not read any of the data passing through them and are not aware of a packets source or destination. Essentially, a hub simply receives incoming packets, possibly amplifies the electrical signal, and broadcasts these packets out to all devices on the network. Typically speaking, three different types of hub exist: 1) Passive 2) Active 3) Intelligent
Passive hubs do not amplify the electrical signal of incoming packets before broadcasting them out to the network. Active hubs, on the other hand, will perform this function - - a function that is also present in a different type of dedicated network device called a repeater. Some people use the term concentrator when referring to a passive hub and the term multiport repeater when referring to an active hub. The NavNet uses an active hub. Intelligent hubs add extra features to an active hub that are of particular importance to businesses.

(2) Cable Category Specifications EIA/TIA category specification provides for the following cable transmission speeds with specifications.
Table 1.2 Cable categories
Category Data rate (Max.) Remarks 1 No performance criteria 2 4Mb/s Used for telephone wiring 3 16Mb/s Used for Ethernet 10Base-T 4 20Mb/s Used for 10Base-T 5 100Mb/s Used for 100Base-T, 10Base-T
(3) What happens when a collision occurs? A collision occurs when two devices transmit at exactly the same time. Since only one device can transmit at a time, both devices back off and attempt to retransmit again. Each device waits a random amount of time and the two are very likely to retry at different times. Thus the second one will sense that the network is busy and wait until the packet is finished. If the two devices retry at the same time, they will collide again, and the process repeats until either the packet finally makes it onto the network without collisions.

1.6 Network setup
1-9
1.6 Network setup The NavNet uses TCP/IP data communication protocol. TCP/IP is a set of protocols which allow cooperating computers to share resources across a network. TCP stands for Transmission Control Protocol (TCP) and IP for Internet Protocol. IP provides the basic packet delivery service for the NavNet. The IP protocol implements a system of logical host addresses called IP addresses. The IP addresses are used by the NavNet to identify devices and to perform internetwork routing. IP is a connectionless protocol, which means that IP does not exchange control information (called a handshake) to establish an end-to-end connection before transmitting data.
The IP addresses are assigned to the NavNet display units before shipment as below. It is necessary to change the last three digits of the IP address when like models are used in a network. Never set the same IP address in the network. The three digits is any number between 001 and 254.

Subnet mask, Gateway address, and Offset port number are not used. Never change these values. (SUBNET MASK: 255.255.000.000; GATEWAY ADDRESS: 000.000.000.000; and OFFSET PORT NUMBER: 10000)
Radar source and sounder source are also selectable through the user accessible Select source menu. When two radars or more are connected in the network, either of them is selected through the Select source menu by the user. Note that at the moment, one netsounder can be used in the network. The Sounder option is for future-use.
Important! The same radar source should be selected on the NavNet plotter display units. Never select different radar source on each plotter display unit if two radars and plotters are in the network. For example, in the network shown in the figure below, radar source must be selected to either M1943C or M1833C on both plotters.
Table 1.6 shows the example of setup menu setting for a network shown in Figure 1.10.

1.7 ARP Function
1-12
1.7 ARP Function In the network shown in Figure 1.12, the radar sends following signals to the plotter.
1) Radar picture 2) Heading data from SC-60 or PG-1000 3) LL and speed data from GP-310B 4) ARP TTM data
Figure 1.12 Signals between radar and plotter
The radar picture includes Heading data so that the display in HU, NU, or CU mode is available on the plotter. TTM data is switched on and off through OUTPUT THROUGH NETWORK menu. A target is acquired and tracking target is erased from the plotter. Note that only one radar in the network can be quipped with ARP board. Table below summarizes controls of radar picture and ARP targets.

Chapter 2. Circuit Description
2-1
This chapter describes the circuit of NavNet series products briefly.
2.1 General NavNet series radar is divided into two groups depending on the type of IF amplifier. One uses a linear IF amplifier and the other a logarithmic amplifier. Figures 2.1 and 2.2 show the simplified block diagram of each system.
TX: The trigger pulse, generated on the Processor (SPU) board in the display unit, is delivered to the modulator in the scanner unit to oscillate the magnetron. The radar emits radio wave from the radiator with the magnetron oscillating.
RX: The 9.4 GHz echo signal received by the antenna is converted down to 60 MHz IF signal by the MIC. The IF amplifier amplifies the IF signal and output it to the video circuit on the SPU board. The signal is displayed on the screen after digital signal processing. The received signal is gain-, A/C sea-, and A/C rain-controlled in the linear IF amplifier, while the signal is not controlled in the logarithmic amplifier but it is controlled in the video amplifier on the SPU board in the display unit.
Auto plotter (Optional): Applied from the SPU board to the ARP board are;
1) Heading in AD format 2) 8192 bearing pulse 3) Video 4) Trigger 5) Ships speed in IEC-61162 format.
The ARP board acquires and tracks targets. Data and symbol of the acquired target are displayed on the screen via the SPU board. Target data includes position, CPU, TCPA, speed, and course.

2.3.1 Auto Tuning Function At not only installation but also the replacement of RF unit, magnetron, MIC, and SPU board, tune initialization must be carried out through the tuning setup menu. The receiver is tuned automatically for maximum echoes and tuning control voltages found are stored onto the EEPROM on the SPU board. Tune initialization is carried out in two steps. First, full search is performed using a long pulse to find a coarse tuning voltage (a). Then, short search is performed for all pulses. After initialization, the pulselength which was used before is selected.
In full search, tune control voltage (TUNE CONT) varies from about 1 V to 10 V and one that produces the maximum tune indicator voltage or coarse tuning voltage is memorized onto the EEPROM.

Figure 2.7 Tuning initialization process
In short search, tune control voltage changes from coarse tuning voltage plus 2.5 V to coarse tuning voltage minus 2.5 V. This search is made with long, middle, and short pulses to find the fine tuning voltage.
At daily use, the short search is made twice when the radar is set from ST-BY to TX and once when the plulselength is changed in auto tuning mode.

2.3.2 Manual tuning When tune mode is changed from auto to manual, the coarse tuning voltage is selected. In manual tune mode, tuning voltage is indicated graphically under the tuning indicator. The minimum scale is 3 V and the maximum scale is 10 V.
2.3.3 Tuning Indication The tuning indicator is adjusted so that the tuning indicator extends more than 80% of its full length on all ranges at best tuning. The extension on short pulse is shorter than long pulse and the indication becomes shorter when the magnetron degrades.
2.3.4 Video Level Adjustment (03P9288/19P1001) The video input level to the linear video amplifier must be adjusted through the installation menu at not only installation but also the replacement of RF unit, magnetron, MIC, and SPU board. The following describes the outline of the adjustment mechanism on the SPU board, 19P1001. The SPU board, 03P9288 has the same circuit as 19P1001, but it has different parts numbers.
The following describes the outline of the adjustment. (These are carried out automatically.) 1. Main Bang suppression Level (MBS L) is set to 0. 2. EEPOT, U14 is set to minimum. (EEPOT initialization with "L" level of U14 #7) 3. EEPOT gets into step-up mode (U14 #2 is H.) to measure output video level at each step.
The step is changed by pulses applied to U14 #1. The step where the output level is 2.2 V is memorized.
4. EEPOT gets into step-down mode (U14 #2 is L) to find and stores the step number where the output level is 2.2 V.
5. Averaging the step numbers found in steps 3 and 4 above, and saving onto depot. The stored value is not erased when power is turned off.
6. MBS L is reset to the value previously used.
Figure 2.8 Video level adjustment
It is not necessary to adjust video level for the video amplifier on the SPU boards, 03P9280 and 03P9286, because the board receives the output signal of logarithmic IF amplifier.

2.3.5 Echo Averaging (EAV) Echo averaging circuit is designed for; 1) Discriminating small and weak targets such as flocks of birds, small ships, and fishing floats
hidden in sea clutter, and 2) Displaying long-range targets stably.
Normally echoes from sea clutter and noises do not appear on the screen at the same position in successive scans. The circuit can provide the different echo levels, correlating echo data at each scan so that the level (intensity) of the echo which appears at random position decreases. For example, echoes from target and sea clutter are displayed on the screen in the same level with EAV off. But the echo from sea clutter is displayed in lower level than target echo with EAV LOW. The return from the sea clutter appears at the different position at every scans and EAV LOW sets the echo level to low at first and second hits. The target echo appears more than three successive scans at the same position, so it gets the maximum echo level. The EAV MED gives the maximum level to the target which has four consecutive hits or more.
The EAV HIGH prolongs the afterglow time of echoes.
Echo averaging is a useful function when it is used properly. However, target may be lost if this function is used with improper settings. The echo averaging requires heading and LL data.

2.4 ARP Function (optional) 10-inch CRT and 10.4-inch LCD radars, Model 1833/1833C/1933/1933C/1943/1943C, provide ARP function if they are equipped with an optional ARP-11. The ARP board cannot be mounted on the 7-inch radars. The ARP-11 has the same circuitry and software as ARP-10, but the board is small in size. The ARP-11 requires heading data in AD format and speed data in NMEA format. Heading data in NMEA format and contact-closure speed log signal are not acceptable.
The ARP-11 acquires and tracks 10 targets manually and automatically. The ARP display can be turned on/off through the ARPA TARGET INFO/ARPA Setup menu which has the following options.
1) Internal ARPA: Is selected when the radar is equipped with the ARP board and when TTM data is received via NETWORK port. Target can be acquired and cancelled from any display unit in the NavNet network.
2) External ARPA: Is selected when the display unit receives TTM data via NMEA port. Target tracks are shown but targets cannot be acquired.
3) Off
Figure 2.10 shows the simplified block diagram of the ARP board, 18P9013.

2.4 ARP Function (optional)
2-12
Unlike other existing ARPs, ARP-11 does not require QV level adjustment at installation and no test point for QV echo is provided.
The system checks the connection of the ARP board at every power-on. If the CPU on the SPU board fails to communicate with the ARP CPU, the message ARP is not connected. appears and the ARP line is not displayed in the selftest display.
The ARP board generates the track of the tracking target. In the radar display mode, the past position is displayed by equally time-spaced dots and in the plotter mode, it is displayed by a solid line. To display the track in the plotter mode, the board memories the position of the tracking target at the same interval as own ships plot interval. A maximum of 10 positions is memorized for each target and these points are connected.
Table 2.1 Display mode vs. track display
Display mode Radar Plotter (GD) Overlay Past Position (dots) Available N.A. Available Track (solid line) N.A. Available Available
When the target is not acquired, carry out the self-test at TX condition. TRIGGER, VIDEO, BP, HD must be OK, and FE-DATA 1 and FE-DATA 2 must vary depending on the gain setting. The lower the gain setting, the smaller the FE DATA value. The FE DATA must not exceed 1000 with the maximum gain setting.
The APR works in the following conditions.
Land echo discrimination A target measuring about 800 m or more in the radial or circumferential direction is regarded as a landmass and not acquired or tracked. Echoes smaller than about 800 m are regarded as true target.
Manual acquisition 1) Within 9 scans, the target must be detected near the cursor position. 2) Target echo must be smaller than land echo (800 m or less in the radial or circumferential
direction) at the front-end processor. 3) Target must be within acquisition area: 0.1 to 16 nm. 4) The number of acquired targets is not as many as 10, including the target manually acquired. 5) No signal error (TRIG, HD, BP, VIDEO, GYRO) shall be detected.
Automatic acquisition 1) The target must be detected for five consecutive scans within the automatic acquisition area. 2) Target echo must be smaller than land echo (800 m or more in the radial or circumferential
direction) at the front end processor. 3) Target must be within acquisition area: 2.0 to 2.5 nm and 45 each side of heading line. 4) The number of acquired targets is not as many as 10, including the target automatically
acquired. 5) No signal error (TRIG, HD, BP, VIDEO, GYRO) shall be detected.

Automatic acquisition 1) A tracking target is judged as a lost target when no return is received for nine consecutive
sweeps. When the system detects a loss of a tracking target, the target symbol becomes a flashing diamond.
2) A lost target will be reacquired and tracked when acquisition condition again becomes satisfactory.
3) Automatic tracking is discontinued when the target moves out of the acquisition range (less than 0.1 nm or greater than 16 nm).

2.5 PWR Board PWR boards, 03P9282, 03P9283, 03P9296, and 19P1005, are similar in circuitry, but the parts numbers are different. The power supply circuit, except for 03P9282, consists of a primary circuit and a secondary circuit. The primary circuit uses a switching regulator and generates 12 V and +12 V. The secondary circuit is powered from +12 V generated by the primary circuit.

On SPU (03P9286) board, -15 V is generated from -24 V by Q13 and CR4 for 7-inch color LCD display.
The following describes how PWR board works in the example of 19P1005.
See Figure 2.11, the block diagram of the power supply circuit, 19P1005. This board consists of main-inverter, sub-inverter, and brilliance control circuit. The main-inverter produces 12 V and +12 V, and the sub-inverter produces +3.3 V and +5 V. On the SPU board, +2.5 V is generated from +5 V with a regulator Q35. The power failure signal P FAIL N is generated by U7 and Q17 before the power supply circuit is shut down.

Protector Circuit (19P1005) The power supply circuit is protected against input low-/over-voltage and short circuit of line voltage. Provided are following power failure detectors.
1) Input over-/low-voltage detector The detector U3 outputs Low signal when ships main is not within the rated input voltage range. CR4 conducts and Q5 turns on. Thus, the switching oscillator U2 stops oscillating with its pin #5 (DT) High. If ships main is not within the range for 5 seconds, 5 sec delay circuit, consisting of Q9, Q11, R28, CR7, and C19, activates with CR5 on. Q12 is on and a reset signal is applied to the flip-flop U4. Q14 and Q13 are off. (C19 is discharged through R28, CR6, and R31.)
If ships main becomes within the range within 5 seconds, the oscillator U2 starts oscillating again.
2) +/-12 V line short-circuit detector When +12 V or 12 V line short-circuits, overcurrent flows in the primary winding circuit of the main-inverter. The overcurrent detector, consisting of U1, R1, R2, and R3, detects this current. The output of U1 becomes low and Q3 is on. Thyristor Q6 is triggered. Q5 is on and the oscillator U2 stop oscillating with its DT pin High.
With Q6 on, 0.5 sec delay circuit activates and Q13 is turned off to switch off 10 V supply.
3) +5 V line short-circuit detector When + 5 V line is short-circuited, U9 stop oscillating. Note that the main-inverter is still alive.
4) +3.3 V short-circuit detector When +3.3 V is short-circuited, overcurrent flows through R87 and R88, causing that Q27 is on. When Q27 conducts, Q19 is on and SCP line becomes Low. A photocoupler U5 triggers 0.5 sec delay circuit and the flip-flop U4 is reset. Q13 is off finally. U9 stop oscillating immediately after the short circuit of +3.3 V line with #3 pin of U9 low.
5) +2.5 V short-circuit detector On the SPU board, a photocouper detects the short circuit of +2.5 V line. The PWR OFF line becomes High and Q6 is triggered.
6) When the CPU freezes, PWR OFF signal is not generated. In this case, hold down the PWR switch for 5 seconds. Q8 and Q9 are on. C19 is discharged through R28, CR6, and R31. CR7 conducts when C19 is discharged to about 3.6 V. Then, Q12 is on.
