RS-422 BOARD
Most PCs used within the C3 Maestro console
application are equipped with a plug-in RS-422 capable
board for serial data interfacing to the CIM within the
CEC/IMC Digital Audio Switch. Normally, no changes from
the factory set-ups are required on this board or any other
related serial COM port hardware within the PC. However,
it may be beneficial to review the information in the section
entitled "
CEC/IMC INTERCONNECTIONS
", subsection
"
Control Data Link
" (page 12) at this time.

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 for the select audio and microphone link. In
addition, each unselect speaker at the console 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 6 and Table 5.
As shown in Figures 1 and 6, all CEC/IMC
interconnections are made via Concentrator Cards. These
cards are located at the back of the CEC/IMC cabinet.
Control data connections are made via Data Concentrator
Cards and audio connections are made via Audio
Concentrator Cards. Typically, as shown in Figure 6, these
connections are extended out of the CEC/IMC cabinet via
Telco cables and terminations are actually made at punch
blocks located external 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
