MINIPLEX System Components
Overview The 4100 MINIPLEX system is comprised of a host panel containing everything required in a
standalone cabinet (see Chapter 3), plus:
• An RUI module in the master controller bay
• One or more remote MINIPLEX transponder cabinets
• A RIC II card in each transponder cabinet
This section describes each component in turn.
The RUI Card The RUI module consists of a motherboard and daughter card, which are used in the master
controller bay of a MINIPLEX system to extend the length of communications wire to reach
remote bays.
Figure C-2 is an illustration of the RUI card.

The RUI card mounts onto a 562-799 or 562-856 Motherboard.
Transponder
Cabinets
Communication wiring from the RUI module in the host panel extends to the RIC II card in a
remote transponder cabinet. The transponder cabinet is simply a 2975-91xx Back Box with a
RIC II module in it, and can have one, two, or three bays.
