One-Cabinet and Two-Cabinet AUDIX System

For new orders, an ACC/ACCE port will be installed at the back of the AUDIX system base cabinet and wired to the backplane.

For upgrades to existing systems, check the base cabinet for an ACC D05 connector. This is a 50-pin Amphenol connector. Order the AUDIX Networking upgrade kit D181965 if this port is missing (comcode 845953108).

Rear Connector Panel and Backplane (Large)

Check the control cabinet for an ACC D06 connector. This is a 50-pin Amphenol connector.

∙If the connector is missing, order the AUDIX Large Networking Upgrade kits D181757 (comcode 105308696) and D182422 (comcode 845798131).

∙If the port is installed, check the label on the cable that goes from the connector to the backplane. It will probably be an ED-1E434-11, Group 373 cable. If the system is to use EIA RS-232 ports for its network, this cable must be replaced with a Group 374 cable — order the AUDIX Large Networking Upgrade kit D182422.

Network Cabling Common to Most Configurations

New AUDIX systems ordered with networking will be shipped two H600-330, Group 1 null-modem adapter cables for the RS-232 ports (see Figure 1-1,H600-330, Group 1 Special AUDIX Null-Modem Cable) and one H600-331, Group 2 breakout cable (see Figure 1-2,H600-331, Group 2 AUDIX Networking Breakout Cable).

Systems that already have networking installed may have the H600-331, Group 1 networking breakout cable rather than the H600-331, Group 2 cable (see Figure 1-3,H600-331, Group 1 AUDIX Networking Breakout Cable). However, the Group 1 cables are no longer shipped.

H600-330, Group 1 Cable

The special null-modem adapter cables are used only for dedicated RS-232 connections. Two are supplied (one for each RS-232 port).

NOTE

The null-modems are unique; do not substitute standard null-modems in this application.
