MODEL 1582-10M Protection Switch
1.0 General
1.1 Equipment Description
-
The 1582-10M 1:1 Switch, 10 MHz provides Auto, Manual or Remote relay
switching between CH1 and CH2, 10 MHz signals. Alarm conditions on CH1 and CH2 are a level drop below
-6 dBm of the 10 MHz signal. The 1582-10M switches from CH1 to CH2 only if CH1 alarms and CH2 is good.
The unit switches back when CH1 is no longer in alarm or both CH1 and CH2 are bad. When power is lost and
when power is applied (as alarms at power up dictate), CH1 is selected. Front panel LEDs indicate CH1 and
CH2 alarms, Remote mode (yellow), and redundant power supplies on (green). Multi-function push button
switches select Auto, Local, or Remote operation and the signal path in the Manual mode. Remote operation via
the RS232/RS485 M&C interface allows selection of CH1 or CH2 and indicates switch position and alarm
status. A contact closure to ground indicates if either or both CH1, CH2 are in alarm. An LCD display shows
Auto, Local or Remote operation and the signal path. Connectors are BNC, female for the 10 MHz signals and
DB9 for M&C and for the alarm contact closure output. The 1582-10M is a 1RU chassis with redundant power
supplies fed by separate fused 100-240 ±10% VAC AC input connectors.
