Chapter 5. REDUNDANT SYSTEMS
The C-Band Transceiver is capable of operating in both stand-alone and redundant
configurations. The CSAT fully redundant system provides automatic detection,
switching, and status for both its configuration and health. The system is designed such
that stand-alone operation is a functional sub-set of the fully redundant CSAT system.
This provides the user with transparent functionality regardless of the mode or
complexity in which the system has been setup to operate.
IMPORTANT
Due to the parallel nature of the M&C interface, only RS-485 and
RS-422 communications are supported through this device.
5.1 Redundant System
Figure 5-1 provides a block diagram for a typical CSAT redundant system.
