1.0 Introduction
The Radyne ComStream RCU101 1:1 Protection Switch Unit provides automatic circuit
restoration for one online frequency Up or Downconverter. The switch provides complete
isolation of primary and backup converters by providing transfer switching of both the RF and IF
signal paths. Converter fault and circuit restoration is initiated from the summary fault contacts of
the online converter. Upon clearing of the fault in the online converter, or after replacement of the
online converter, the switch can be directed to restore the operation to the online converter (or
the converter that is selected as the ‘online’ unit). An RS485 Equipment interface between the
converters allows the backup converter to ‘learn’ the gain and frequency settings of the online
unit.
