1.0 Introduction
TheACE-RIUisacompact,48kHzdigitalandaudiodistributionmodulethatconnects
remotelylocatedoperatorstationsandliveradiostotheAudioCommunicationsEnvironment
Network(ACENet).TheACE-RIUiscompatiblewiththeTelestraandVoisusplatforms.The
ACE-RIUprovideslow-noiseanalog-digitalconversionandlow-latencyaudiodistribution.
TheACE-RIUintegratespress-to-talk(PTT)units,volumecontrols,simulatedcom-
municationspanels,handheldterminals,andliveradiosintothesimulatedcommunications
environment.
TheACE-RIUincludesthefollowingfeatures:
lFourdigitalinputs(i.e.,oneperchannel,fourchannelstotal)
lFourdigitaloutputs(i.e.,oneperchannel,fourchannelstotal)
lTwoRS-422serialports
