H600-331, Group 2 Cable

All new AUDIX networking systems are shipped with one H600-331, Group 2 breakout cable. One end of
the Group 2 cable is a 50-pin male Amphenol connector that connects to the ACCE on the AUDIX system.
The other end of the cable has a 50-pin female Amphenol connector and two 25-pin RS-232 male
connectors. See Table 1-1 for the pin assignments.

The female Amphenol connector provides access to the four DCP channels (AUDIX networking channels
1, 2, 3, and 4). The RS-232 connector A provides access to one RS-232 channel (AUDIX networking
channel 5), and RS-232 connector B provides access to the other RS-232 channel (AUDIX networking
channel 6).
