1:2 LNB/LNA controller

Redundant systems increase system availability by including two or more of the same type of equipment (unit) in the signal path, where at least one unit serves as a backup for the others. The backup may be switched in to replace an on-line unit if a fault is detected in that unit.
Common types of redundant systems are 1:1, which consists of two units, one on-line and one backup; and 1:2, which consists of three units, two on-line carrying two separate channels, and one backup that can replace either of the on-line units. Less-common Dual 1:1 systems consist of two pairs of 1:1 systems (four units total) in one installation, with one redundant pair on each channel.
The RSC series of redundant system controllers are capable of controlling various types of equipment in 1:1, 1:2, or Dual 1:1 systems. They can directly power most LNA or LNB units and monitor the output voltages and currents to detect faults. The RSC can also monitor external alarm signals, such as summary alarms from SSPA units, or a combination of output currents and external alarm inputs. Upon detecting a fault, the RSC drives an RF transfer switch to activate the spare unit.
The RSC offers monitoring and control of auxiliary RF hardware; remote monitor and control via network, serial interface, or parallel I/O; flexible configuration of the system behavior; remote disable of local controls for security; and the ability to detect and report certain failures within the controller itself.
Remote Control Panel Option
A second RSC can be linked to a primary RSC to provide full system control from an alternate control site. When set up this way, the secondary RSC is referred to as a remote control panel, or RCP. The configuration and settings of the primary RSC are transferred to the RCP, which then mimics its controls and interfaces. This permits system operation from a location that is up to 4000 ft (1200 m) distant from the primary controller.
Configuring an RSC to become an RCP (and the reverse) can be done through the front panel controls by the user.
