2.1.2 Radio Interface Module (RIM)
The RIM/RIM-M is a service specific RF conditioning module
that interfaces to the RF signal source. An IHU chassis can
support between 4-8 RIMs.
Each RIM supports both Simplex and Duplex RF connectors.
LEDs provide status indications on signal level and module
operation status.
