DARPlus

A versatile point-to-point microwave system for conventional video and audio, as well as digital transport at rates up to 120 Mbps, the DAR Plus is field-switchable between analog and digital, requiring only a few switch settings in the RF shelf to be changed, and is easily reconfigured thanks to the user friendly DAR Plus Menu System – which provides full control of the radio, with alarm reporting and status.


While it offers both video and audio modulation for NTSC and PAL formats with four audio channels – all the analog components are contained on two plug-in modules for easy swap out and service - perhaps the DAR Plus' greatest feature is the variety of digital transport options. It can be configured for ATSC using MRC's QM2 internal or external modems. When used with MRC's Variable Rate Modem, four user-selectable IF carriers can be multiplexed into one datastream, with data rates up to 120 Mbps.

To protect your signal path, the DAR Plus can be configured for hot standby on both the transmitting and receiving ends. Additionally, the MRC Hot Standby Diversity Shelf enables "errorless" switching on the receive end for maintaining data integrity.
