Section 1 - RCU101 1:1 Protection Switch Description

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 swit c hing of bot h the RF and IF
signal pat hs. Conv ert er f ault and c ircui t restorat ion i s initi ated f rom the summ ary f ault contacts
of the onl ine conv erter. Upon c learing of the faul t in t he online conv erter, or after replacem ent
of the online converter, the switch can be directed to restore the operation to the online
conver ter ( or the converter t hat i s select ed as the ‘onl ine’ uni t ). A n RS485 Equi pm ent i nt erf ac e
between the converters all ows the backup converter to ‘learn’ the gain and frequenc y settings of
the online unit.
