The Model 2082-14x-series of Redundant Unit Controllers are designed
to power, monitor and control LNA or LNB amplifiers configured in 1:1
or 1:2 redundancy modes. There are currently two (2) Drive Voltages
supported (+26 or +47 VDC) and two (2) Common (voltage or ground)
configurations. This manual addresses all eight (8) of these models as
shown in this chart:
Front panel LEDs indicate power, status (online, standby, alarm), and

mode (auto, manual, local, remote). Up to 600 ma is available to power each amplifier. LNA or LNB current is measured and a fault
is signaled if the current deviates from user selected thresholds. Multi-function switches select Auto, Local, or Remote operation,
(Priority for 1:2 models), and the signal path in the Manual mode. Remote operation via the RS232/RS485 M&C interface allows
selection of priorities (1:2) and the signal path. Ethernet is available as option, -W8, -W18, or -W28. Contact closure to ground inputs
allow selection of Local/Remote, andAuto/Manual Modes. An LCD display shows each amplifier's current, and signal path. Form C
relay contact closures indicate amplifier and power supply status, waveguide switch position, Auto, Remote, and Manual operation.
Connectors are DB37 for contact closure I/Os, MS3112E16-23S for the amplifier plate signals, and DB9s for monitor and control and
auxiliary external contact closure alarm inputs. ALL 2082-14x models are housed in a 1RU chassis which are powered by redundant
power supplies fed by separate, fused 100-240 ±10% VAC AC input connectors.
