AnaCom's Protection Switch System
provides a high reliability 1 for 1 Hot-Standby configuration for
ANASAT® C and Ku-Band transceivers, ELSAT L-Band BUCS, and a
combination of our ELSAT BUCs and an LNB. The Protection Switch System
is ruggedly built for continuous outdoor duty in all types of environments.
The Protection Controller is designed for simple, intuitive operation.
TX and RX switches function independently.
The Protection System consists of a Protection
Controller out-door box, and WR-229 and WR-137 waveguide switches
for C-Band applications, or a pair of WR-75 waveguide switches for
Ku-Band applications. Both switches include waveguide terminations
for the off-line equipment. Only a single RS232/1485 interface cable
is required to interface to indoor computer/dumb terminal.

PROTECTION SWITCH SYSTEM FOR ANASAT Transceivers and ELSAT BUCs
Compact, Functional Design
AnaCom's Protection System integrates all necessary functions
into a small, highly integrated outdoor package which is designed
to give highly reliable service in a wide range of environments.
The Protection Controller is fully contained in a single, small
out door box with manual over-ride controls. Although normally intended
for un-manned, automatic operation, the switch can be locally (or
remotely) over-ridden to place a particular TX or RX switch (or
both) on line and defeat the normal "switch-on-alarm"
mode of operation. A single push-button (or remote command) returns
the unit to completely automatic operation.
BITE Facility
To improve and simplify maintenance routines, an external terminal
(or computer) can be connected to monitor a number of critical parameters
without use of additional test equipment. These include:
|
Transceiver alarm status (TX, RX; A and B) |
|
Switch alarm status |
|
Switch position status |
Controllable functions from the terminal include:
|
Force TX switch to the A side |
|
Force TX switch to the B side |
|
Force RX switch to the A side |
|
Force RX switch to the B side |
|
Restore AUTOmatic operation |
Comprehensive Monitor &
Control
The Monitor and Control feature allows you to monitor and control
the Protection Controller and both transceivers on the same RS232/RS485
M&C bus.
An MS DOS based Software provided with each Protection Switch for
use in combination with a PC for monitoring and controlling both
transceivers and the Protection Switch System from one computer
display. Only one RS-232/RS485 cable is required from the computer
to the outdoor equipment.
