High-Power TWTA Satellite Terminals Redundant System Installation
Rev. 1 3–27
3.4.2 External Connections
All connections are made at the rear panel of the controller (Figure 3-7). With the
exception of prime power, which should be connected last, the timing and sequencing of
the controller connections are not critical. However, the correct TWTA connectors must
be connected to the corresponding set on the rear panel of the controller.
The HPC-1110 provides for a discrete interface for monitor and control of the TWTA.
The HPC-1110 provides inputs for switch position indicators (2 pins and common). All
other connections are not used.
