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.
