BOARD SET-UP

IMPORTANT NOTE

Unless otherwise noted, all procedures in this manual should be performed in the order presented.

LOGIC BOARD

Normally, the Logic Board is configured correctly and installed inside the PC before the C3 Maestro console system is delivered to the customer. The following information is presented for reference only.

DIP Switches

SW1 −− Dual-Port Address DIP Switch

All positions of DIP switch SW1 on the Logic Board should be in the "ON" or "CLOSED" position. This sets the base address of the dual-port RAM chip on the board to D000:0000 (hex). SW1 switch should never be configured in any other way. Figure 2 shows the "0000" setting.

Data General Dasher 386SX/20

Data General* 386/25A

Compaq 386S

* Manufactured for Data General by Acer; all plastic case.

Operating System Software

The PC will have either MS-DOS version 3.3, 5.x or

6.x installed on its hard drive. MS-DOS 5.x or 6.x is preferred. All Data General and Hewlett-Packard computers ship from the factory with either MS-DOS 5.x or

6.x. MS-DOS 4.x is not approved for use with the C3

Maestro console system.

Figure 2 −− Logic Board SW1 Factory Setting

SW2 −− Interrupt (IRQ) DIP Switch

DIP switch SW2 on the Logic Board sets the board's interrupt request (IRQ) line. It should be set with position 1 "ON" or "CLOSED" and all other positions "OFF" or "OPEN". This sets the interrupt to seven (IRQ7). Normally, SW2 should not be configured in any other way. Figure 3 shows the setting. This setting is not a binary-code decimal equivalent representation of the interrupt number; the switch simply provides a single-pole four-throw switch function using four single-pole single-throw DIP switches.

Logic Boards previous to Rev. A were not equipped with SW2; the interrupt was hardwired as IRQ7.

Firmware

EPROM integrated circuit U4 on the Logic Board stores the operating program firmware for the on-board microprocessor. After programming at the factory, the EPROM (part number 344A4245Gx) is labeled with the corresponding firmware version number. C3 Maestro application software version 3.0x requires Logic Board firmware version 3.02 (part number 344A4245G10) or later. If necessary, verify the proper EPROM is installed into U4's socket.

Installation Into The PC

The Logic Board is installed in an expansion slot inside the PC. Although it can be installed in any slot, installing it in the slot furthest from the PC's internal power supply is recommended. If field installation is necessary, follow this procedure:

1. Review the procedures in the documentation included with the PC related to expansion board installation.

2. If necessary, power-down the PC and disconnect it from the ac power source.

3. Remove the outside cover from the PC in accordance with the manufacturer's instructions.

Audio PA Board(s)

SW1 −− Maximum Speaker Power Level DIP Switch

Switch SW1 on the Audio PA Board provides a method to limit the maximum audio output from each speaker power amplifier. Maximum levels of 5 watts or 8 watts are available. Normally, the factory setting is 5-watts. This level is recommended, as it should be adequate in nearly all dispatch environments. Table 2 indicates the available settings and Figure 4 shows the 5-watt factory setting. These switches have no effect o n headset earphone output levels.

NOTE

SW1 is not present on Audio PA Board

P29/5000055000. Both speaker power amplifiers

on this earlier board (sometimes referred to as a

"Phase 1" board) are hardwired for 8 watts

maximum output. See LBI-38716 for details.

4. Select an empty expansion slot and remove the respective rear cover plate. Retain the hold-down screw. Discard the rear cover plate.

5. Install the Logic Board in the selected expansion slot. Secure it with the hold-down screw.

6. Replace the outside cover.

PLUG-IN RS-422 BOARD (Optional)

If the PC is equipped with a plug-in RS-422 capable

board, see the section entitled "INTERCONNECTING

THE EQUIPMENT", subsection "CEC/IMC INTERCONNECTIONS" for set-up information.

AUDIO TOWER

All necessary slide-in boards are installed in the Audio Tower before the C3 Maestro console system ships from the factory. If the console system is ordered with multiple unselect speakers (2 or 3) or with the Call Director patch option, two Audio PA Boards are installed. DIP switches and jumpers/plugs located o n the Audio Matrix and Audio PA Boards are factory configured for standard console installations. The following information lists the normal factory settings and the optional settings which are available.

amplifiers' source audio from the Audio Matrix Board (normal) to Line A and Line B balanced inputs (test), respectively. See LBI-39064 for specific details. With this test setting, audio signals on the line inputs are applied directly to the speakers' power amplifiers without being routed through the Audio Matrix Board.

NOTE

SW2 is not present on Audio PA Board P29/5000055000. Audio source selection on this earlier board (sometimes referred to as a "Phase 1" board) is accomplished via two jumpers/plugs identified as JP1 and JP2. During normal (nontest) console operations, jumpers must be in between pins "A" and "C" on both plugs. These settings route Line A and Line B audio signals from the Audio PA Board to the Speaker A and Speaker B power amplifiers. See LBI-38716 for additional details.

TABLE 3 −− AUDIO PA BOARD

AUDIO SOURCE SELECTION

As shown in Figure 6, Audio Matrix Boards ship from the factory with all mic audio ALC circuits enabled. This is accomplished by setting all four SW1 switch positions to "ON" or "CLOSED". Table 4 lists each switch position a nd its corresponding mic input. Normally, mic audio ALC should not be disabled. Disable a mic's ALC by setting the corresponding DIP switch position to "OFF" or "OPEN".

maintenance manual, LBI-38939 for sample print-outs and complete print-out explanations.

Control Data Link

Either an RS-422 (four-wire) or an RS-232 (threewire) serial control data link may be employed. RS-422 control data interfacing is recommended and in most all installations, it is used for co-located console interconnections. RS-232 has poorer noise performance than RS-422 and therefore, it should never be used for cable runs more than 50 feet in length.

If required for a remote console installation, fullduplex 4-wire data modems can be used between the C3 Maestro and the CEC/IMC. See the following subsection for additional remote console wiring and modem configuration details.

At the C3 Maestro, control data connections terminate at the PC's COM1 serial port. On the CEC/IMC side, the console's control data connections are made at a Data Concentrator Card. As shown in Figure 8A, punch blocks may be installed between the CEC/IMC and the console. Also shown in the figure, a Concentrator Card Cable interconnects the Data Concentrator Card to the CIM Controller Board via the CEC/IMC Backplane.

• Audio Tower-to-Call Director

IMPORTANT NOTE

Unless otherwise noted, all procedures in this manual should be performed in the order presented.

CEC/IMC INTERCONNECTIONS

The C3 Maestro console interfaces to the CEC/IMC via a full-duplex serial control data link and a 4-wire audio connection. In addition, each unselect speaker requires a n additional 2-wire connection from the CEC/IMC. Also, if the console is interfaced to a Call Director for Call Director telephone patch operations, an additional 4-wire audio link between the C3 Maestro and the CEC/IMC is required. See Figures 1 and 8. As shown in Figure 8, all CEC/IMC interconnections are made at Concentrator Cards. These cards are located at the back of the CEC/IMC cabinet.

CEC/IMC Concentrator Card pin-out details are listed on the customer-specific system documentation print-outs. These print-outs are included with the CEC/IMC when it ships from the factory. See the CEC/IMC Digital Audio

Switch Customer-Specific System Documentation

All Data General (DG) Dasher computers are factory equipped with a built-in COM1 serial port on the main board that can be wired for RS-422 or RS-232 operation. The connector is a DB-25 type. See Figure 8A.

Computers not equipped with a main board RS-422 capable COM1 port normally have a plug-in RS-422 board installed in an expansion slot. This board has a DB-25 connector at its rear plate. Approved RS-422 plug-in board model numbers include RS422AT-P, RS422I-P and 3PXOCC1A. An RS422x-x board (part number 344A3927P38) can easily be identified by the presence of two LED indicators visible on its rear plate. If a plug-in RS-422 board is used, the PC's main board COM1 port must be disabled. This is done via a DIP switch, jumper, or a BIOS set-up program. For COM1 port enable/disable configuration details, refer to the section entitled "SOFTWARE INSTALLATION AND SET-UP

PROCEDURE", subsection "PC CMOS SET-UP PROGRAM" later in this manual, and the PC

manufacturer's documentation.

Factory-installed RS422x-x (344A3927P38) or 3PXOCC1A plug-in boards are configured correctly before the PC ships from the factory. This configuration includes disabling the PC's main board COM1 port per manufacturer's instructions.

See Figure 8A or the manufacturer's documentation for COM port connector pin-out details. Interconnect the control data connections between the PC and the appropriate CEC/IMC Data Concentrator Card as required. Shielded pairs are recommended.

Remote Console Interconnections Via A 4-Wire Modem

When the C3 Maestro is installed at a remote location from the CEC/IMC, serial control data must be routed via RS-232 connections and 4-wire modems. Since the C3 Maestro requires a dedicated or continuous serial link (nondial-up), a 4-wire leased line (or equivalent) meeting 3002 data grade specifications must be employed between the CEC/IMC and the C3 Maestro in a remote console installation.

Figure 8B shows typical control data interconnections for a remote console installation using RS-232 connections and full-duplex 4-wire modems. At the CEC/IMC Data Concentrator Card, RS-232 connections are made at J13,

not J12. Observe all notes listed in the figure if wiring an installation of this type. Recommended modem settings

Dispatcher Keyboard

The dispatcher keyboard interfaces to the PC via circuitry on the Logic Board. Its part number is P29/7590182002 (344A3927P25). This keyboard is sometimes referred to as the "custom keyboard".

Connect the dispatcher keyboard to the PC by plugging its 4-pin interlocking plug to the round socket at the Logic Board's rear cover plate. If the Logic Board is vertically orientated, this socket is located just above the female DB37 connector. When correctly mated, the red dot on the plug will be in a 3 o'clock or 9 o'clock position if the Logic Board is vertically orientated.

If disconnection is necessary, pull on the sleeve and not on the cable. Pulling on the cable will not free the latch and may damage the cable if excessive force is used.

Standard PC Keyboard

During dispatch operations, the standard PC keyboard is not used. However, during the console set-up process, access to this keyboard will be required:

• for file management (for example -

AUTOEXEC.BAT and CONFIG.SYS file changes may be necessary)

• to configure certain items via the Editor program

(see LBI-39056 for details)

• to start and operate the CTEST test program

• to start the console's application program

Connect the standard PC keyboard to the PC in

accordance with the manufacturer's instructions.

Volume Controller Box (if used)

If the console system is equipped with speakers, the Volume Controller Box must be used. Typically, it is located under the video display monitor but it may be placed at any convenient location within cable reach of the Audio Tower. The supplied cable is ten (10) feet in length.

The cable used with the Volume Controller Box has male DB-15 connectors on both ends. Its part number is P29/1030049000. Mate one end of this cable to the DB-15 connector at the back of the Volume Controller Box. Mate the other end to the female DB-15 connector labeled "VOLUME CONTROLLER" at the bottom of the Audio Tower's rear panel. This connector is located on the Spreader Board.

Footswitches (if used)

Two (2) female DB-9 connectors are located on the I/O

Board for footswitch interconnections. "FOOTSWITCH 1" keys the desk mic and "FOOTSWITCH 2" keys the headset and boom/gooseneck mics. Footswitches used with the C3 Maestro dispatch console include single-footswitch option CRSU3B and dual-footswitch option CRSU3C. On the dual-footswitch, one switch keys the mic and the other switch is a monitor switch. Each input is wired in parallel at the following points and thus may be activated from any one of several locations. See the schematic in the appropriate board's maintenance manual for specific connector pin-out details.

• B/G PTT input is located at the "B/G PTT" &

• Monitor switch input is located at the "B/G PTT"

Each Audio PA Board installed in the Audio Tower that has speakers connected to it must have a "jumper" cable connected between its "VOLUME CONTROLLER" DB-9 connector and the Spreader Board. The "jumper" cable's part number is P29/1030048000. If the second Audio PA Board (#2) is used only for Call Director interfacing, it will not have any speaker connections and it will therefore not require a "jumper" cable.

Only one "jumper" cable is required for a 2-speaker console. A 3- or 4-speaker console which is equipped with two Audio PA Boards requires two "jumper" cables. Connect a "jumper" cable between the first Audio PA Board's connector labeled "VOLUME CONTROLLER" and the connector labeled "A" on the Spreader Board. The first Audio PA Board (#1) is located in the slot adjacent to the Audio Matrix Board. If the console system has 3- or 4speakers, connect a second "jumper" cable between the second Audio PA Board's connector labeled "VOLUME CONTROLLER" and the connector labeled "B" on the Spreader Board. The second Audio PA Board (#2) is located in the Audio Tower's far right-hand slot as viewed from the back of the Audio Tower.

NOTE

Refer to LBI-38715 if the C3 Maestro console system is equipped with "Phase 1" Audio Matrix, Audio PA, I/O or Backplane Boards. All "Phase 1" boards have P29/500000xx00x part numbers and all "Phase 2" boards have P29/772xxxxxxx part numbers. When using any "Phase 1" board, external CD interface transformers and other special modifications are required for Call Director interfacing.

Install a 4-wire balanced line (two pairs) between the required CEC/IMC Audio Concentrator Card and Audio PA Board #2 in the Audio Tower. See the prior section entitled "CEC/IMC INTERCONNECTIONS" for additional details on the Audio Concentrator Card pin-outs. Terminate the Audio PA Board’s LINE D with an RJ-11 modular plug. RJ-11 pin-outs are shown in Table 5. Shielded cable is recommended.

Table 10 describes the audio signals between the Audio Tower’s Audio PA Board #2 and the CIM within the CEC/IMC. The descriptions are relative to the Audio Tower. All audio signals on these 600-ohm pairs have typical levels of 0 dBm.

Call Director (if equipped)

As shown in Figure 1, all C3 Maestro-to-Call Director interconnections at the console are made at the Audio Tower's I/O Board. Call Director telephone patch also requires a second Audio PA Board (#2) in the Audio Tower and a 4-wire balanced line between this board and the console’s CIM within the CEC/IMC. At the CEC/IMC, CIM audio channel/line four (4) is used for Call Director interfacing. CD control data interfacing is handled over the existing RS-232/RS-422 serial control data interface between the PC and the CEC/IMC. Refer to Figures 1, 7, 8 and 12 for Call Director interconnection details.

Console-to-CEC/IMC Audio Interconnections

All audio in to and out of a C3 Maestro dispatch console system enters and leaves the console via modular jacks on the Audio PA Boards. Both Audio PA Boards have the same "LINE A" and "LINE B" labeling at the modular jacks. As shown in Table 6, "LINE A" and "LINE B" labels on the second Audio PA Board (#2) are considered LINE C and LINE D respectively. Figure 7 shows modular jack locations. LINE C, if used for a second unselect speaker, connects to CEC/IMC CIM channel/line 3. Call Director LINE D connects to CEC/IMC CIM channel/line 4.

Console-to-Call Director Interconnections

Table 11 describes the various signals between the Audio Tower’s I/O Board and the Call Director. The descriptions are relative to the Audio Tower. All I/O Board connections are made at the "CALL DIRECTOR" female DB-9 connector. Figure 12 shows the connector's pin-out.

EQUIPMENT ROOM GROUNDING

Proper grounding techniques should be observed in order to protect the equipment and service personnel from lightning and other sources of electrical surges. All consoles should be connected to properly grounded 3terminal outlets. If used, lightning arrestors, UPS equipment, and all other console-associated equipment should also be properly grounded.

AC POWER AND UPS EQUIPMENT

All consoles require 120 or 230 Vac (47 to 63 Hz) power sources. As a minimum, each outlet should be circuit-breaker protected per local building codes.

UPS protection is optional. Maximum required UPS wattage rating for a single console system should be based on the required maximum sums of the Audio Tower (200 watts max.), the PC's computer (per manufacturer's specifications) and the PC's video display monitor (per manufacturer's specifications).

POWER-UP PROCEDURE

The following C3 Maestro power-up procedure is recommended:

1. If the PC and/or monitor are equipped with a voltage selector switch, verify the switches are positioned correctly. The power supply within the Audio Tower automatically switches itself and therefore no voltage selection switch exists.

2. Verify all power switches are in the off position.

3. Connect the PC, video display monitor and the Audio Tower to a 120 or 230 Vac source. Some computers are equipped with a receptacle on their rear panel for the monitor's ac power connection. Refer to the PC and monitor documentation as necessary. Extension cords should not be used with the C3 Maestro console system.

4. Verify all equipment is properly grounded.

PC CMOS SET-UP PROGRAM

C3 Maestro software is factory-installed on the PC's hard disk drive and the software is configured properly for standard installations. Therefore, during a typical console configuration, the information in this section may be bypassed.

All PCs used with the C3 Maestro store start-up configurations in CMOS memory. This information is read by the computer's BIOS and it may be changed by executing a set-up program during the PC's boot process. Execute the PC's set-up program only if a built-in (main board) COM1 port must be disabled/enabled or if documentation included with the PC deems it necessary for some other reason.

NOTE

Time and date will be correctly set by the

CEC/IMC Manager (MOM PC) when the console

is on-line with the CEC/IMC.

Hewlett-Packard Vectra 25N & 486SX/25

Typically, the set-up program is started by pressing <F2> when prompted with "For Setup press F2 now" during the boot process. COM1 is disabled by setting "Serial Ports/Port A" to "Off". An HP 486SX/25 computer should also have its "Serial Port B" set to "COM2 2F8H INT3". Be sure to save the change(s) before rebooting/resetting (typically via pressing <F3>).

5. Power-up the Audio Tower.

6. Power-up the PC and its monitor.

7. Continue with the software installation and set-up procedures that follow.

EDITOR PROGRAM

If necessary, the Editor program (EDITOR.EXE) can be used to change one or more or the following parameters (non-inclusive list):

• Logic Board Interrupt (IRQ)

• COM1 Serial Port Baud Rate

• Set-Up Titles

• Call Director ID

• Boom/Gooseneck Mic Presence (version 2.x and

previous only)

Except for the Call Director ID parameter, these parameters cannot be changed via the CEC/IMC Manager (MOM PC).

NOTE

CEC/IMC Manager (MOM PC) version 2.x (and

earlier) also did not provide support for Call

Director ID; this parameter also had to be set via

the Editor program.

LBI-39055

Most console-related configuration parameters should be changed at the CEC/IMC Manager and sent to the console. Users of the Editor program must understand the CEC/IMC Manager should be the central point of databasing and configuration for all C3 Maestro consoles connected to the CEC/IMC Digital Audio Switch. Changes made locally via the Editor program will override settings previously made via the CEC/IMC Manager. Correspondingly, changes made via the CEC/IMC Manager will override settings previously made via the Editor program.

At the PC's standard keyboard, execute the Editor program by typing EDITOR followed by an <Enter> from an MS-DOS prompt. The current directory must be C:\CONSOLE. See the LBI-39056 for additional details on the use of the Editor program.

Logic Board Interrupt (IRQ)

The Logic Board's interrupt software configuration must match the interrupt number set by DIP switch SW2 (hardware configuration) on the Logic Board. Refer to the previous DIP switch configuration information in this manual and LBI-39056 for details.

If necessary, use the Editor program to set the interrupt as required and save the change to the hard disk drive. Most all systems will use interrupt 7 (IRQ7). This is the factory (default) setting.

COM1 Serial Port Baud Rate

In C3 Maestro console systems, the baud rate of the COM1 serial port can operate at 19,200 or 9600 baud. The 19,200 setting is recommended. 9600 baud may be required when a data modem is employed between the console and the CEC/IMC.

If necessary, use the Editor program to change the baud rate. Save the change to the hard disk drive. 19,200 baud is the factory (default) setting. See LBI-39056 for additional details.

Set-Up Titles

From the Editor program's "USER PROFILE DATA" screen, enter the titles as required. These titles are displayed on the C3 Maestro's "Change Setup" notecards. Ten (10) titles, each with thirty-one (31) alphanumeric characters, are available. See LBI-39056 for additional details.

Call Director ID

Call Director ID is a secondary console ID number that is only used for Call Director telephone patch operations.

The default value for this ID is zero (0) − no Call Director. Valid Call Director ID range is 1 - 16382. The zero setting should not be changed unless a Call Director is attached to the console and the console will be used for Call Director patch operations. The ID resides in the unit/console ID space and it should therefore be a unique (unused) ID number. Console ID and Call Director ID should never be

identical.

If using CEC/IMC firmware version 2.x (and earlier), set the Call Director ID number from the Editor program's "CONFIGURATION DATA" form. Save changes to the hard disk drive. See LBI-39056 for complete details.

If using CEC/IMC firmware version 3.x (and later) the Call Director ID setting should be made via the CEC/IMC Manager's "Console Hardware Configuration" option and then sent to the console.

Boom/Gooseneck Microphone Presence

C3 Maestro firmware/software version 2.x required the Editor program to manually set the presence/absence of a boom/gooseneck microphone. However, firmware/software version 3.x and Logic Board Rev. B hardware automatically sense the presence of a boom/gooseneck microphone via a hardware line from the BOOM/GOOSE MIC connector. Therefore, this item was removed from the Editor program version 3.x, as it is no longer required. If using firmware/software version 2.x, set this option using Editor program version 2.x as required.

NOTE

All boom and gooseneck mic connectors (male

DB-9) must have pins 2 and 3 jumpered together

so the sense circuit will be active when the mic is

connected to the Audio Matrix Board.

RUNNING THE C3 MAESTRO APPLICATION PROGRAM

The C3 Maestro application program will automatically start when the PC is powered up via the CONSOLE(.EXE) statement in the AUTOEXEC.BAT file. After exiting the program, restart it again from the PC's standard keyboard by typing CONSOLE followed by an <Enter> at the MS-DOS prompt. The current directory must be C:\CONSOLE. In addition, the CONKEY.COM program which is also run via the AUTOEXEC.BAT file a t boot-up, allows the C3 application program to be quickly restarted by simply pressing function key <F10>. In a new console installation, after starting the program, databases

LBI-39055

must be initialized as described in the following section before dispatch operations can be performed.

DATABASE INITIALIZATION

When the console initializes from a cold start, all of the following sections should be performed to insure proper operation. All console databases are initialized via commands from the CEC/IMC Manager (MOM PC). See the CEC/IMC Manager operations guide LBI-38911 (version 2.x) or LBI-39024 (version 3.x) for additional details.

Basically, except for sending console configurations, all procedures presented in this section assume all CEC/IMC console configurations are complete as described in the CEC/IMC Digital Audio Switch Installation, Set-Up And Troubleshooting maintenance manual, LBI-38938. See "STEP 6 - CONSOLE CONFIGURATION" in LBI38938 for details.

Console User Profile Configuration

From the CEC/IMC Manager, user profile data is sent only to the targeted console. When a target console receives user profile data from the CEC/IMC Manager it will send an acknowledgment to the CEC/IMC Manager. Send user profile data to the console as follows:

1. From the CEC/IMC Manager's "CEC/IMC MOM

Options" main menu, select the "Console Configuration" option. This will display the

console configuration sub-menu.

2. From this sub-menu, select the "Console User Profile" option. This will display the "CONSOLE USER PROFILE CONFIGURATION" screen.

3. Verify the "CONSOLE" number matches the CIM's console number as defined by the CIM's DIP switches.

appears or no message appears after ten (10) seconds, the CIM may not be properly installed and/or configured. Check Controller Board installation and DIP switch settings. A "User Profile Successfully Written..." message must be received before continuing with the next procedure.

System Manager Database Uploads

System Manager databases contain all system information for all defined entities (units, groups, sites). These databases can be downloaded by the console by requesting database uploads from the CEC/IMC Manager. Since this data is broadcast to all consoles in the CEC/IMC system, if possible, all consoles should be on-line when this upload occurs. This avoids having to repeat the process for other consoles at a later time.

1. From the CEC/IMC Manager's "CEC/IMC MOM

Options" main menu, select the "System Manager Data" option. This will display a sub-

menu.

2. Select "Upload From System Manager".

3. From the "SYSTEM MANAGER UPLOAD STATUS" screen, select <F1> then <F8> for a full unit upload. After the upload is complete, exit the screen by pressing <Esc>.

4. From the "SYSTEM MANAGER UPLOAD STATUS" screen, select <F2> then <F8> for a full group upload. After the upload is complete, exit the screen by pressing <Esc>.

5. From the "SYSTEM MANAGER UPLOAD STATUS" screen, select <F6> then <F8> for a full site upload. After the upload is complete, exit the screen by pressing <Esc>.

6. From the "System Manager Data" sub-menu, select the "Upload From MOM PC" option.

4. Verify the "Unit ID" number does not conflict with that of any other console or radio ID number in the system.

5. Select the correct "Setup" and then make any required modification(s) to the configuration. If required, save the new configuration.

6. Press the <F7> function key to send the Console User Profile configuration to the console.

❏ Send the LINE A input to the SPKR A output by

typing the following commands:

NOTE

If no headset is connected to the Audio Tower the initial audio matrix switch settings will route the LINE A input to the SPKR A output. Therefore, in this case, execution of the above commands is not necessary.

❏ Verify the 1 kHz tone is heard in Speaker A.

CTEST's VU meter should indicate yellow.

❏ Adjust the select speaker (Speaker A) volume knob

up and down and verify the volume changes. This knob is the left-most volume knob on the Volume Controller Box.

❏ Turn the tone off by typing the following

commands. The first command will turn it off:

❏ Verify the 1 kHz tone is heard in Speaker B. If

not, send the LINE B input to the SPKR B output by typing the following command:

<F2>

❏ Adjust the unselect speaker (Speaker B) volume

knob up and down and verify the volume changes.

❏ Turn the tone off by typing the following

command:

<F2>

Successful completion of this tests verifies basic

operation of the following:

<Enter>

• Line B input circuitry

• Speaker B power amplifier circuitry

• PC and Logic Board's ability to control the cross-

point audio matrix switches on the Audio Matrix Board

• Volume Controller Box unselect volume control

and its related cabling

3. Send Mic Audio To LINE A & LINE B Outputs

❏ If necessary, connect a headset to operator headset

jack box. Verify this jack box is connected to the OPERATOR HEADSET connector on the Audio Matrix Board (#1).

Successful completion of this tests verifies basic

operation of the following:

• Line A input circuitry

• Speaker A power amplifier circuitry

• PC and Logic Board's ability to control the cross-

point audio matrix switches on the Audio Matrix Board

• Volume Controller Box select volume control and

its related cabling

• VU meter circuitry

2. Send LINE B Input Audio to SPEAKER B

❏ Remove the RJ-11 modular plug from the LINE A

jack and connect it to the LINE B balanced input. The balanced input is the two outside contacts on the RJ-11 modular jack (yellow and black wires i n a modular cable).

❏ Terminate the Audio PA Board's (#1) LINE A

balanced output terminals with a 600-ohm resistor. The balanced output is the two center-most contacts on the RJ-11 modular jack (red and green wires in a modular cable). Connect an oscilloscope across this load resistor.

❏ Send operator headset mic audio to the LINE A

output by typing the following commands:

❏ Speak into the headset's mic and verify the audio

signal is present on the LINE A balanced output. Maximum signal level is approximately 6 Vp-p.

❏ Turn the operator headset mic-to-LINE A audio off

by typing the following command:

<F2>

❏ Verify mic audio is no longer on the LINE A

balanced output.

❏ Move the LINE A balanced output 600-ohm

termination to the LINE B balanced output.

<Enter>

LBI-39055

❏ Send operator headset mic audio to the LINE B

output by typing the following command:

❏ Speak into the headset's mic and verify the audio

signal is now present on the LINE B balanced output. Maximum signal level is approximately 6 Vp-p.

❏ Turn the operator headset mic-to-LINE B audio off

by typing the following commands. The audio should turn off after the first command is entered:

❏ Verify mic audio is no longer on the LINE B

balanced output.

Successful completion of this tests verifies basic operation of the following:

• operator headset mic input circuitry

• Line A and B output circuitry

• PC and Logic Board's ability to control the cross-

point audio matrix switches on the Audio Matrix Board

4. Test Audio PA Board #2 (if installed)

If a second Audio PA Board is installed in the Audio Tower, the following procedure can be used to test it:

❏ Power-down the Audio Tower and swap the #1

board with the #2 board.

❏ Power-up the Audio Tower.

❏ Repeat steps 1, 2 and 3.

❏ Power-down the Audio Tower and swap the #1

board with the #2 board.

❏ Power-up the Audio Tower.

5. Completion

❏ Remove all test connections and reconnect the

RJ-11 modular plugs from the CEC/IMC to the

LINE A and LINE B modular jacks on the Audio PA Board (#1).

HIGH-LEVEL TESTS

The following high-level tests verify basic operational status of control data and audio interfaces between the C3 Maestro console and the CEC/IMC. The procedures assume all equipment has been interconnected and set-up in accordance with the previous instructions presented in this manual.

Control Data Link

The C3 Maestro console and the CIM within the CEC/IMC periodically poll each other over the control data link. If this link is not operating correctly the console will display a "Com Error: link down @xxxxx bps" error message on the PC's video display monitor. This link must be up (operating) before any dispatch operation can occur. For troubleshooting information, refer to the CEC/IMC

Digital Audio Switch Installation, Set-Up and Troubleshooting maintenance manual, LBI-38938. The

console-to-CIM link up/down status can also be viewed via the CEC/IMC Manager's (MOM PC's) "SYSTEM DISPLAY" screen.

Upon restoration of a failed console-to-CIM control data link a "Communications error condition cleared" message is displayed.

Audio Links

After determining the control data link is operating by the lack of an error message, audio link operation can be tested. To test, program a module with a test group and then place a call to and from a test radio set the same group. Also test the operation of all unselect speakers. Verify the console can send and receive audio. If necessary, refer to the C3 Maestro console operator's manual. Refer to LBI-38938 for troubleshooting information.

If the console is is equipped with a Call Director, test Call Director patch operation by patching a radio to a telephone line. See the operator's manual for details.
