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.

Figure 2 − Logic Board SW1 Factory Setting
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.
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
Audio PA Board(s)
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.
SW1 − Maximum Speaker Power Level DIP Switch
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:
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 on 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.
1.
Review the procedures in the documentation
included with the PC related to expansion board
installation.
2.
If necessary, power-down the PC
disconnect it from the ac power source.
3.
Remove the outside cover from the PC in
accordance with the manufacturer's instructions.

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 on 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.
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 and
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".

IMPORTANT NOTE
Unless otherwise noted, all procedures in this
manual should be performed in the order

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 an
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
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.
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.

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

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

Spreader Board.
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

considerably. Speaker damage may also occur.
These terminals are intentionally not labeled with
polarity to help prevent any of the terminals from
being connected to ground or to another amplifier.
Recorder Outputs (if used)
To provide call-check recorder support, select and
unselect audio outputs are available from the Audio Tower.
These 600-ohm outputs appear at the top terminal block on
the I/O Board. Unselect audio appears on the two terminals
labeled "UNSELECT RECORDER" and select audio
appears on the two terminals labeled "SELECT

enable) input are included. The terminals are labeled
"PAGE INPUT" and "PAGE PTT" respectively.
Pager audio on "PAGE INPUT" is switched in when
"PAGE PTT" becomes active. "PAGE PTT" is active
when its two terminals are shorted together by a relay
contact (or equivalent) in the pager. During a page, no
other audio signals are applied to the Line A output. Also,
the paging signal is sent to the headsets and speakers
approximately 16 dB lower than other audio signal levels.
Connect the pager to the terminal block in accordance
with the manufacturer's instructions. As shown in Figure
11, the two (2) upper terminals on the terminal block are
the "PAGE INPUT" connections and the two lower

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)
Console-to-Call Director Interconnections
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.
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.
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.

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
PC CMOS SET-UP PROGRAM
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.
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.
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 thePC'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.
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.

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.
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.
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.

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 at
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

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.
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.

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 sendand 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.
