Electrical Safety Notice

This equipment has been designed to minimize exposure of personnel to hazards. All

operators and technicians must

• Know how to work around, with, and on high-voltage equipment.

• Exercise every precaution to ensure safety of personnel.

• Exercise extreme care when working near high voltages.

• Be familiar with the warnings in this manual.

CAUTION

CAUTION indicates a hazardous situation

that, if not avoided, could result in minor or

moderate injury. CAUTION might also be

used to indicate other unsafe practices or

risks of property damage.

HIGH VOLTAGE

HIGH VOLTAGE indicates the presence of a

high-voltage hazard.

WARNING

WARNING indicates a potentially

hazardous situation that, if not avoided,

could result in death or serious injury.

CHAPTER

HAPTER

NTRODUCTION

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

Reference Documents

Use the satellite operation standards listed in Table 1.1 as reference documents.
