1.1 Overview
A complete redundant system consists of:
•
RC-1160 or RC-1260 redundancy switch controller
•
Redundant amplifier plate with two or three LNA/LNBs
•
Interconnect cable up to 1500 feet (457 meters) in length
The redundancy switch controller performs the following functions:
•
Supplies +14V power to the LNA/LNBs.
•
Measures LNA/LNB current.
•
Performs calibration on LNA/LNB current.
•
Signals a fault with abnormal current deviation.
•
Sounds audio alarm on fault (can be disabled).
•
Switches LNA/LNB on a priority basis in auto mode.
•
Controls waveguide and coaxial switch position.
•
Provides FORM-A and FORM-C relay contacts for remote status.
•
Provides a 9-pin EIA-485/-232 serial interface.
•
Normal/maintenance switch online during servicing.
