This User Guide is intended for users of Terrasat Communications, Inc. receive
redundant (Rx 1+1) systems.
Receive Redundant Systems
The Rx 1+1 system enables switching of low-noise block converters (LNBs) via a
waveguide switch that switches the RF receive signal, and an RF relay (internal to the
interface module) that switches the IF signal. The Rx 1+1 system includes a separate
outdoor interface module that does not require an indoor controller. It can be powered
by the same power supplies used with Terrasat intelligent block upconverters (IBUCs)
or via AC mains and performs all the required functions for redundant operation of
LNBs.
This manual provides information about:
• Installation, operation, and maintenance of Rx 1+1 systems
• Use of user interface protocols for remote monitor and control
