1. Visualize your goal

Your CM3000 Networked Amplifier / Controller can be a component of a Conductor IP-based paging system or an ezRoom classroom AV management system. When your CM3000 is part of an ezRoom installation it might look like this:

Step 1: Before you begin

1

The FrontRow CM3000 is an amplification and control device that is used in ezRoom® classroom AV management systems and in Conductor™ paging, bell and intercom systems. This one device switches and amplifies analog audio, encodes/decodes streaming audio, auto switches between local classroom audio and IP audio, includes a four port network switch, and allows for “pass though” control of serial devices such as a projector. It resides on an IP network so it can be accessed remotely and securely to execute its functions.

3. What do you want to amplify? What do you want to transmit and to what device?

Your CM3000 can amplify and switch a variety of audio inputs, and can control devices with serial interfaces. Now is the time to plan what you want to do.

Example 1: Typical ezRoom setup with a projector

In the ezRoom Installation diagram on page 1, the CM3000 works with other ezRoom components to turn a projector on and off, switch audio inputs, handle the transport controls for a Blu-ray player, and control audio volume from the teacher’s computer, an MP3 player and two FrontRow wireless microphones. If Conductor is being used in the school the CM3000 can also amplify PA announcements and provide for two-way intercom calls between the ezRoom classroom and the office with Conductor.

Example 2: Typical Conductor setup

You can also use the CM3000 to manage the intercom and paging audio for the Conductor system in the front office. The Conductor Head End Installation diagram on page 2 shows a configuration with which a school administrator can make an announcement or page via the FrontRow CB65 microphone and the CM3000 will encode the analog audio into stream-ing (or IP) audio for transmission over Cat 5/6 cables and the LAN. Also, when a teacher communicates with the front office via intercom, the CM3000 converts the streaming audio to analog audio and plays it over the front office speakers.

4. Gathering Information

You will save a lot of time by working with the school to gather information up front.

Will this CM3000 be used as part of a Conductor setup or an ezRoom setup? If part of a Conductor setup:

• The IT department will provide you with IPv4 for the CM3000, Shuttle Touch Screen PC and DRS5000 Server.

If the CM3000 will be part of an ezRoom setup:

• Make a list of all rooms to be outfitted and the equipment to be controlled in each one.

• The IT department will provide you with IPv4 addresses for each CM3000 and other FrontRow IP addressable components (these must be static, or fixed, IP addresses), along with other network information, such as the subnet mask, router IP address and Frontrow server IP address.

• Will the room include a FrontRow Symbio™ wireless voice amplification system?

• Will the room be served by a Conductor system for paging? For intercom?

• Will there be an IR-controlled device?

• Will the room controller be a FrontRow CB2000 or CB6000?

5

• Organize the network information in a spreadsheet such as the one found at http://gofrontrow.com/how-to/room-control-project-planning-template.xls:

6

Your CM3000 has several parameters that can be configured to tell it how to communicate with other devices in an ezRoom or Conductor installation. While each installation is different most of the default parameters will be appropriate.

1. Connect to your CM3000

• Connect your laptop computer’s LAN port to the CM3000 LAN 1 port with a CAT-5, or network, cable.

• Change the IPv4 address on your laptop to static address 192.168.1.100. See Appendix B for instructions.

• Open a web browser on your laptop and in the URL field type the IPv4 address 192.168.1.103 and press enter. This is the default static IP address of the CM3000 and will likely be changed when you configure it per the school’s IP addressing scheme.

• You will be connected to your CM3000 and see a screen like this:

Step 2: Configuration

CM3000 - Left Side

2. Name your CM3000

The name you choose should contain meaningful information, such as the classroom number, so that a person accessing the device remotely will have appropriate context. Also on this screen you can see the device MAC address and firmware version.

3. Secure your CM3000

If the project requires it you can password-protect the CM3000 configuration screens by setting Security Level to Admin after which a person can access the configuration screens only by entering the password. (If Security Level is set to None, no password is required.)

The old password is calypso. Choose a new one based on the school’s guidelines and record the information.

8

4. Set audio parameters

In this section you can make adjustments to the CM3000 audio behavior to customize it for a specific ezRoom installation. The default values of most parameters will provide optimal performance for most installations, and noted below are where adjust-ment should be made.

Volume Presets

• Startup refers to the volume level when the device is powered up. 0 is lowest and 32 is highest.

• The Presets can be used to send a control code that sets the CM3000 to a preset volume level. For most installations this is not used as one can send an exact volume command to a CM3000 directly.

Channels 1, 2, 3 and 4

• When checked Enable allows the audio signal on that channel to be used as an input to the device.

• Startup designates which channel will be active at device power up. Typically this would be Channel 1.

• Gain adjusts the input level of a channel so that when necessary it can be balanced with higher or lower inputs to level match with other channels.

• The CM3000 supports ducking, which is the automatic decrease of audio volume on other channels when there is audio on the priority channel. Mic designates the priority channel, and by convention Channel 4 is selected.

• Relatedly, Setback specifies how low the volume of the non-priority channels is set when audio is present on the priority channel. 0 designates no volume decrease and -32 would mute the channel.

• Also, Threshold specifies the audio level necessary on the priority channel for ducking to be invoked. The default set-ting of 32 is appropriate for the average classroom. In a room with substantial ambient noise however, that noise may be picked up by the teacher’s microphone and invoke undesired ducking. This can be overcome with a higher Threshold setting, though the drawback is the teacher would need to speak louder. An alternative is to set Setback to 0, which essentially turns off the ducking feature.

Channel 5

• This channel refers to the IP streaming audio coming in to the LAN 1 or 2 port.

• As with Channels 1, 2, 3 and 4, Startup designates which channel will be active at device power up. Typically this would be Channel 1.

• PA Detect needs to be set to Both if the CM3000 is in an ezRoom installation that is integrated with a Conductor system. Even if not however, there is no reason to use another setting.

• Relatedly, when the CM3000 is part of an ezRoom installation that is integrated with a Conductor system, Threshold specifies the sensitivity of IP audio level detection that will invoke ducking. This is typically not changed from its default value because the Both setting under PA Detect will allow for the trigger upon presence of an IP audio stream.

Other Settings

• Amp Gain sets the output gain for the device, and is typically set to the level of 32db.

• When the CM3000 is part of an ezRoom installation that is integrated with a Conductor system, PA Volume specifies the volume level of pages and bells.

• Relatedly, PA Restore specifies the length of time after the paging or bells audio ceases that the other audio inputs are taken out of mute and returned to their previous volume levels and state.

• Mic Restore is similar to PA Restore, but applies to the microphone audio.

• With Mute mode one can choose to mute only the amp speakers or also the line out audio when the MUTE command is received from Encore! control software, a CB6000 CB2000 wall controller, or Maestro software.

• With Balance the balance of right versus left speaker(s) can be adjusted.

• Save Settings will save any adjustments made on this screen.

Audio Settings displays the current settings.

5. Set codec parameters

In this section you can make audio codec (equalizer) adjustments. The default values of most parameters will provide optimal performance for most installations, and we note below where adjustment should be done.

Audio codec configuration

• Line Out default Gain adjusts the gain for the analog line outputs.

• Intercom default output Gain adjusts the gain for the intercom streamed output from a Conductor system.

• RFB adds additional gain adjustment for a wireless microphone that is plugged in to the Wireless Mic port.

• MIC adjusts the gain of an audio source plugged in to the Audio Streaming Input port.

• Intercom adjusts the gain for intercom devices CB75 or CB85. Boost and Gain allow for adjustments of the Intercom volume levels when switching between different microphone types (such as the FrontRow CB65 or CB75).

10

Other Settings

• VOX Level should not need to be changed; unless you are an experienced audio engineer and are working with unusual installation requirements please leave this set at 128.

• When used with a TB-13 adaptor Enable audio detect triggering enables the detection of an audio signal from a legacy (e.g., non-Conductor) paging system so as to duck other audio inputs; this is one of the two events that need to be specified to enable “Priority Page Override,” which is discussed further in the description of the screen Event Detection later in this document.

• Relatedly, Trigger Level specifies the level of audio energy needed to trigger the page override feature. The higher the number the more audio energy is needed to trigger the page override. This is to ensure that a noisy paging system doesn’t inadvertently trigger the page override.

• Also, Silence Timeout specifies the length of time between cessation of a page and the resumption of other audio.

• Save Settings will save any adjustments made in this section.

Audio Equalization configuration

• Unless you are an experienced audio engineer and are working with unusual installation requirements, please leave these parameters set at their default levels.

Audio Codec/EQ settings displays the current settings.

11

6. Enable networking

Device network configuration

• Automatic IP configuration (DHCP) causes the CM3000 to request an IP address from a DHCP server; this should be enabled only if the IT department has a DHCP server online and has set up static (fixed) IP address reservations for CM3000 devices; otherwise manually enter the IP address reserved for the device in the IP Address field.

• The IP Address field displays, and also enables entering, the IP address for the device; while the default address for a CM3000 is 192.168.1.103 you must use the address provided by the IT department and ensure that each device has a unique address.

• The IP Subnet Mask is provided by the IT department; if the CM3000 is used as part of a Conductor system the subnet mask must be 255.255.255.0.

• The Router IP Address is required when the CM3000 is in a network in which switches determine cross subnet connectivity.

• The Primary NameServer IP Address and the Secondary NameServer IP Address are optionally provided by the IT department.

• Save Settings will save any adjustments made in this section.

Device port configuration

• Web Server Port is the default port used for web services and always set to 80.

• Remote Management Port specifies which port controllers are to use to for network commands; while the default is set to 7262 be sure that the CM3000 is set to the same port number as the controller devices.

• Remote Port Idle Timeout specifies how long the CM3000 will wait for a network device to respond before terminating the network session (i.e., before giving up); this can be a useful parameter when the network is large and/or congested, but it normally is not enabled.

• Save Settings will save any adjustments made in this section.

12

7. Serial Ports

• The COM Port menu specifies the COM port number that the parameters on this page apply to; the CM3000 has only one COM port.

• Baud Rate specifies the data speed at which the CM3000 should communicate with the attached serial device; while 9600 and 19.2K are typical for projectors, data speeds vary by manufacturer.

• Stop Bit is specified by the manufacturer but is typically 1.

• Parity is specified by the manufacturer but is typically None.

• Save Settings will save any adjustments made in this section.

8. Streaming

Unless you are an experienced audio engineer and are working with unusual installation requirements, please leave these parameters set at their default levels.

13

9. Miscellaneous

Use this screen to configure the CM3000 to be part of a Conductor system for intercom and/or PA.

Intercom/PA Stream Mode configuration

• Checking Intercom device tells the Conductor server that this CM3000 is part of the intercom system.

• Checking Master device tells the Conductor server that this CM3000 has a microphone and is allowed to initiate pages. This is set only when the CM3000 is part of a Conductor admin station, not when it is simply a part of the intercom system.

• Heard on AMP speakers specifies that intercoms and paging are heard on the ceiling speakers in an ezRoom; when the CM3000 is part of a head end installation it specifies that intercoms are heard on speakers attached to the CM3000.

• Heard on Intercom speakers specifies that intercoms and paging are heard on the intercom (the CB75) in an ezRoom.

• Save Settings will save any adjustments made in this section.

Push to talk configuration

• PPT Mode refers to a CB75 “push to talk” configuration choices, which are offers Disabled (always handsfree), After push (initially handsfree), Always (never handsfree).

• Switch assignments should not be used unless you are an experienced audio engineer and are working with unusual installation requirements.

• Save Settings will save any adjustments made in this section.

IR configuration

• Unless the CM3000 is to be controlled via IR these settings do not apply. Even if controlled via IR these settings will not likely need to be changed.

INTERCOM Connection configuration

• Rotary Mode is used with a CB75; choose AMP direct if there is no intercom functionality and you want to use the CB75 for local classroom audio control; choose Intercom so the push to talk (PTT) microphone can be used for classroom intercom; Off disables the rotary knob.

• Save Settings will save any adjustment made in this section.

14

Run Calibration is a legacy feature that doesn’t apply to a CM3000.

10. Enter Command

Use this section to send control commands to a device to verify that it performs the action desired.

Choose the command from the (Select an entry) menu and complete it with device and other specific information in the Send Command field. Submit it by pressing the Send CMD button.

Control feedback requested in the command sent will be displayed in the Receive Command field if specified within the control command. If no reply is requested Command successful will be displayed; this only means that the CM3000 successfully sent the command. In practice, the most salient feedback is gotten by observing the device itself.

See Appendix A for more detailed information on CM3000 commands.

15

11. Event Definition

The CM3000 is an amplifier, an encoder/decoder for audio over IP and an IP switch, but it can also store predefined commands that are executed when certain triggers occur. The menu of commands is the same as that shown in the previous screen, and the following screen shows triggers to initiate commands.

This screen enables associating triggers (numbered 1 through 7, and associated with the New Event field) with commands. There are navigation buttons to facilitate editing.

Under Alarm one can specify that an alarm sounds when a trigger occurs.

Under Action one specifies the specific command that gets executed when the trigger occurs.

16

12. Event Viewer

This screen shows for each trigger what command will be executed (if any). Checking the green box will simulate a trigger to enable testing the trigger/command combination.

Note that triggers 5 and 6 represent legacy paging systems (i.e., not a Conductor system) audio start and audio stop for the Page Override feature.

• Events 1 and 2 are triggered by the GPI of the CM3000 (open and close)

• Events 3 and 4 are triggered from the CB75 push button if so programmed and configured

• Events 5 and 6 are for page override and are typically set to “Mute” and “Unmute”

• Event 7 is no longer used by the CM3000.

17

13. Choose file store

The set of configuration parameters created by the previous screens can be saved in a file for use with other CM3000s. In this section you would “save” a configuration file or “load” a file from a location on your computer. Some of the parameters would still need to be changed (e.g., the IP address).

18

Nearly everything you need to install your FrontRow CM3000 is included in its shipping box, or in the shipping box of the ple-num or wall enclosure containing the CM3000. However, you will need some basic tools and materials, depending on how your classroom is built.

Recommended tools and materials

• Plastic cable (zip) ties

• Cable tacks/staples

• Drill (or hammer drill for concrete walls)

• Drill bits (masonry bits for concrete walls)

• Slotted screwdriver

• Level or ruler/tape measure

• Crimp pliers or scissors

• Ladder

• Staple gun

• Safety goggles

General safety precautions

• Do not install or use the CM3000 near water or a heat source

• Clean only with a dry cloth

• Protect all cables from wear and damage from doors or other hazards

• Use only accessories specified by FrontRow

• Refer servicing to qualified service personnel

• Wear safety goggles when using power tools

Step 3: Physical Installation Prep

19

Estimated time for this step: 3 – 10 minutes

Now it’s time to decide where you’ll place the CM3000. If it is part of an ezRoom configuration:

* Be sure to refer to the Installer Guides for the various ezRoom components for best results.

• Locate the CM3000 (and optional plenum or wall enclosure) near a power supply and the classroom’s network drop.

• Typical maximum cable lengths are 330’ for CAT 5 network cable runs, 50’ for RS232, and 50’ for IR. Typical maximum lengths for speaker cables are 50’ though please refer to the applicable FrontRow product documentation for specific requirements. For AV plates please refer to the specific AV plate documentation.

If your CM3000 will be part of a Conductor setup, locate it close to a power source and LAN drop.

Connecting your CM3000 in an ezRoom installation

1. Plug the power supply jack into the 12VDC (3.5A) power socket.

Step 5: Install your CM3000

2. Connect the Channel 1 mini-audio jack to the LINE IN 1 port. Any combination of ports can be used. The default jumper position for LINE IN 1 is for balance mode. The typical configuration is to use LINE IN 1 for computer audio, LINE IN 2 for a video device (composite video with stereo with RCA audio), and LINE IN 3 for audio from an HDMI source. However, any configuration is supported.

9. If your classroom is connected to the school’s analog paging system (i.e., a legacy system, not a Conductor system), your CM3000 can mute classroom audio sources when it detects a page, providing greater intelligibility and a safer environment for students and staff in the event of an emergency. To integrate your CM3000 to the analog paging system for paging override, connect a FrontRow TB13 connector and Phoenix connector (not provided with your CM3000) to the AUDIO STREAMING IN / PAGE OVERRIDE port. For easier installation in an ezRoom enclosure, use a right-angle adaptor (not provided).

Connecting your CM3000 in a Conductor installation

1. Plug the power supply jack into the 12VDC (3.5A) power socket.

2. Connect the network cable for the school LAN to the LAN 1 port. (Cable isn’t provided with your CM3000.) For convenience the LAN 2 port can be used to connect the Shuttle Touch Screen display to the network.

3. Connect the CAT 5 cable from the FrontRow CB65 microphone to the INTERCOM port of the CM3000

4. Connect the speaker output of the admin station CM3000 to the passive speakers as provided in the admin kit.

TroubleshootingI’ve connected a new CM3000 to my computer for configuration but I can’t communicate with it

• If you are using a Windows computer, clear the ARP cache. Form the command prompt and with administrator authorization, enter:

ARP –D IPADDRESS (e.g., ARP –D 192.168.1.104).

I’ve already programmed a CM3000 but can’t find the IP address

• Download the SpyGlass app from http://gofrontrow.com/files/documents/software/Spyglass_v110.zip and follow the instructions in the PDF of the downloaded archive. Spyglass is a Java-based utility designed for discovering FrontRow network devices such as the CM3000, which exist on your network.

The sound from the Blu-ray player, AppleTV and teacher’s computer cuts out for a few seconds intermittently

• In a room with ambient noise the teacher’s microphone may pick that up, inadvertently invoking the automatic ducking feature. You can raise the Threshold parameter as set in the Audio screen, though keep in mind that the teacher would then need to speak louder. Alternately, you can set the Setback parameter to 0, which essentially turns off the ducking feature.

I’ve connected the serial cable from the CM3000 to the projector and I’ve verified that baud rate and other settings are correct, but I still can’t control the projector.

• Try switching the TX and RX wires. In a 9-pin connector the standard is to use pins 2 and 3 for TX and RX, but there is no standard as to which is which. Most manufacturers use pin 2 for TX and pin 3 for RX, but over 10% use the reverse.

I’ve forgotten my password and need to reset the device.

• Resetting your CM3000 involves the same procedure as that for many FrontRow devices: briefly shorting the COM 1 RX and TX terminals.

1. Create a shorting connector by inserting the ends of a piece of wire into a Phoenix connector where the RX and TX will be when plugged in to the COM 1 port, and tighten the screws.

2. With the device powered down, insert the shorting connector into the COM 1 port.

3. Power up your CM3000.

4. After 3 seconds (one one thousand, two one thousand, three one thousand) remove the shorting connector.

5. If the Run / PGM LED is flashing blue the device has been reset to the default settings for the password, which will be calypso, and IP address, which will be 192.168.1.103. Other parameters you may have set – including whether or not a password is required to access the device – will be unchanged. If the LED is not flashing, repeat the procedure with slightly more time or slightly less time.

6. Power cycle the device to end the flashing.

Appendix B: Network SettingsThis section describes how to change the setting of your computer’s wired network adapter to use a fixed (or static) IP address rather than an automatically assigned address through DHCP. The screen shots for this procedure were taken from a computer running Windows 7, and while other versions and other operating systems will look different, the general procedure is identi-cal. The goal is to get to the screen where you can change your network adapter from “Obtain an IP address automatically” (referred to as “DHCP”) to “Use the following IP address” (referred to as “static”).

1. Click on the Windows Start button located on the lower left portion of your screen.

2. Click on Control Panel.

3. Click on View network status and tasks.

Note that your computer may be set up differently and you may see an alternate view, such as that shown below, in which case select Network and Sharing Center.

34

4. Click on Change adapter settings. Note that your computer may display different wording such as Manage Network Connections.

5. Double click on Local Area Connection.

35

6. Select Internet Protocol Version 4 then click the Properties button.

7. Select Use the following IP address. In the IP address field enter 192.168.1.100. This is the static IP address to use when connecting to FrontRow networked devices. Click into the Subnet mask field; it may automatically fill in 255.255.255.0 but if not type it in. Click the OK button and close each of the popups.

36

8. To return your computer to its original condition where it uses DHCP, follow the same steps described above but select Obtain an IP address automatically, press the OK button and close each popup as before.

Appendix D: Changing CM3000 Line outputs from balanced to unbalancedThe CM3000 Line outputs can be configured for balanced or unbalanced output by changing the jumper settings in side the box. As of spring 2014, FrontRow began shipping units with the line outputs set to unbalanced to work best with Audio Out

wall plates for bringing audio into the classroom for PFM systems or computer input.

Here’s how to tell how your unit is currently set:

1. If the unit has a Calypso logo then the line outputs are set to Balanced by default, unless there is a sticker on the output that specifies “Line Out 1 (UNBAL)”

2. All units with the FrontRow logo will be set to Unbalanced by default.

To change the line outs from Balanced to Unbalanced, you will need to open the CM3000 unit.

Step 1: Remove the 4 screws on the sides of the CM3000

Step 2: Remove the cover of the CM3000

38

39

Step 3: Change the jumper positions to unbalanced.

This will affect both Line Out 1 and Line Out 2.

Jumpers set to balanced Jumpers set to unbalanced

Step 4: Replace the top and secure with the screws

The best way to re-assemble the cover is to slide it over the base slightly tilted to avoid the LEDs, until the connections on the Line Out side click into the openings in the top, then carefully drop the lid down so that the LEDs fit into the openings in the top.
