Overview
The RCS-8120 Modules provide a convenient method of controlling the Ross family of utility
switches (AVS-8064, DSS-8024, and ADS-7864).
Each switch panel has 2 dual push button switches (switch “A” and switch “B”). Two audio type
connectors and 1 BNC connector are provided for each switch. These connectors allow easy interface
to the Ross family of utility switches or to the RCM-8120 remote panels.
The RCS-8120 is designed to be mounted in the MRP-8120 1RU mounting panel (which can hold up
to 5 modules), or mounted in desk with the DCA-8120 in desk mounting adapter. Blank cover plates
are available for unused positions on the MRP-8120.
Each of the switches on the RCS-8120 can be used for one of two things:
1. To provide GPI control of a Ross utility switch. Connect a coax from GPI A BNC (GPI B
BNC for the B switch) on the RCS-8120 to the DSS-8024 or AVS-8064 it is to control. To
connect to an ADS-7864, use A Right for the A switch (B Right for the B switch). When the
left switch is pressed in, the GPI will be open. When the right switch is pressed in, the GPI
will be shorted.
2. To select between two RCM-8120 panels connected to the same control bus (see owners
manual for the RCM-8120). Connect J1 (J3 for the B switch) to the panel you want active
when the left button is pushed in, J2 (J4 for the B switch) to the panel you want active when
the right button is pushed in.
Note
If selecting between two RCM-8120 modules, ensure that pin 1
on the J1 connector at the RCM-8120 is not connected to the
cable.
