2.3.3. RS-232 Serial Port Connections

The COM port signals are standard RS-232 with no hardware flow control. The directions of the signals
are indicated in Table 2-1. The RS-232 port on the AUDIO AND AUX I/O connector is used for control
and data logging of status and fault conditions. Control and data logging is done with custom software
that communicates with the 7735AVC-LB card using the AVC Control/Status Protocol. For more
information about configuring the data logging output, see sections 7.8.2 and 9.
The RS232 port is also used for extracting and uploading configurations to 7735AVC-LB cards using the
ConfigSet software (included). For more information on ConfigSet see section 8.

INSTALLING THE BULKHEAD BREAKOUT PANEL

The 7760AVM-BHP Bulkhead breakout panel (an accessory designed for our 7760AVM modules) can
also be used with the 7735AVC-LB cards. It provides the user with a convenient way of connecting the
audio and GPI/O signals into the HD DB-15 connectors on the rear of the modules. This panel occupies
1.5 units of rack space and is designed to be mounted at the rear of the user's rack panel. The breakout
panel can be used to connect up to ten AVC modules. Each of the ten sets of connectors on the breakout
panel is fitted with two BNCs for AES audio out, two six position terminal strips for the 4 channels of
analog audio, and one six position terminal strip for the GPI/O and RS-232 signals. Figure 2-4 shows one
section of the breakout panel. On the rear of the breakout panels are 10 female HD DB-15 connectors.
To connect the AVC module to the breakout panel, connect the 15 pin extender cables supplied with the
breakout panel between the AUDIO AND AUX I/O connector on the rear of the AVC module and the
appropriate D connector on the breakout panel. The user must make sure to secure the connectors with
the screws supplied. The audio and aux cables can be secured into the removable portion of the terminal
strips using a small screwdriver. The removable part of the terminal strip is inserted into the breakout
panel and secured using the two hold down screws.
