Model AD2083-02C AD RS-422 Distributor Installation and Operation Instructions
7
Data Line Connectors
Two DATA LINE BNC connectors are provided on the rear panel, labeled IN and OUT. The IN is used to receive
control codes from the 1995 or the 1996/1024 CPU of the 2050 systems. The OUT is a loop through connection.
If this device is the final device in a daisy chain, the BNC must be terminated in 75 ohms. Use RG-59U video
cable for all connections.
Note
When 1995 or 2050/1024 systems with existing B/W/S Control Code interfaces are used, they can be
connected to the AD2083-02C Control Code Connector, as shown in Figure 5.
RS-232 Connectors
Two RS-232 connectors on the rear panel, labeled INPUT and OUTPUT, are provided for alarm interface
connections. The output port is for connection to the switcher/control system alarm input ports or for cascading to
another AD2083-02C unit's input port or a 2096 Alarm Interface unit. The baud rate is set for these ports as
shown in Table 2.
The RS-232 connectors are 8-pin modular type RJ-45 connectors. The pin-out definitions for the two connectors
are shown in Table 5.

Remaining Pins - No Connection
The AD2083-02C connects to switching systems with a modular cable 6003-0047-02, when distances between
the units are no further than 7 feet apart.
Note
The pin definitions as listed require modular cable 6003-0047-02, or similar (that is, a cable that inverts the
connections).
For connection to switchers where the distances exceed 7 feet, a modular cable with a wall-mount 8-pin Terminal
Block, Figure 6, is provided for plug-in to the rear panel connectors. The pin definitions for this block are the same
as in Table 5. See Appendix for typical connections.
