Controller for Redundant Systems High-Power TWTA Satellite Terminals
6–2 Rev. 1
6.1 Overview
The HPC-1110 provides complete monitor and control of the EFData TWTAs in a
redundant configuration.
The EFData digital controllers are modular units, factory-configured for a variety of
redundant system arrangements. Configuration at the factory provides a consistent user
interface across a broad spectrum of systems. The controller configuration is specified
when the system is purchased.
The controller can be operated in Local or Remote mode. In the Local mode, the
controller front panel displays redundant system operation, the high voltage of the
TWTAs, and reset of TWTA faults. Front panel indicators display the status of the
system.
For a 1:1 system, the controller (which is hard-wired to the TWTAs via discrete serial
interfaces) connects one of the TWTAs (the primary unit) to the operational load (online
unit). The other TWTA (the backup unit) is connected to the offline load.
Two serial interfaces (RS-232-C and RS-485) are provided for remote control of the
redundant system controller. In the Remote controller mode, full M&C capability is
provided for both the controller and TWTAs. Both serial interfaces allow remote control
of the redundant system and both channels are always active.
Refer to Section 1.3 for HPC-1110 specifications.
Refer to Chapter 3 for installation instructions.
