PERSONAL COMPUTERS
In most cases, the Personal Computer (PC) used with
the C3 Maestro console is delivered with the Logic Board
installed, its hard disk drive formatted and MS-DOS
operating system software installed on the hard disk drive.
The C3 Maestro application software is also installed on
the drive.
Hardware
Table 1 lists the PCs approved for use with a C3
Maestro console system. Use of an unapproved computer
will void the console system's warranty and support
services. Subsequent to the printing of this manual,
additional PCs not listed in the table may be approved.

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".

INTERCONNECTING THE
EQUIPMENT
A C3 Maestro dispatch console system requires the
following interconnections:
• PC-to-CEC/IMC Data Concentrator Card
(via punch blocks, if employed)
• Audio Tower-to-CEC/IMC Audio Concentrator
Card (via punch blocks, if employed)
• PC-to-Audio Tower
• PC-to-Dispatcher Keyboard

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
