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
6.1 Interface 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.
6.2 Single 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.
