6 CONTROL MODULE SWITCHING (LOCAL)

The switch function designators for the three momentary toggle switches located on the front panel of the control module are termed:

1.A/B MASTER

2.ENABLE

3.ALARM RESET

6.1Interface Converter Module (PSR-06A)

The Interface Converter Module is used in conjunction with the Control Module to provide compatibility between a PatchSwitch Control Module and an RS-232 control device (modem computer, CRT or RCU). Only the first PS Chassis in a group needs to have a PSR-06A installed.

6.2Single Channel Switching

To switch a PS module, the operator toggles the ENABLE switch to either off-center position while simultaneously toggling the channel's A/B switch (located on the PS module) in the desired direction. The channel switching operation does not require the operator to maintain the toggled position of either switch while waiting for the module switch function to occur. Once the toggling operation is performed, the circuitry senses the switch change and completes the module switching operation upon receiving an internal timing signal.
