Power Supply Rear Connections
The rear connections (convection-cooled model shown; fan-cooled model not illustrated) for each of
the power supply are:
the power supply are:
Fail Alarm –
Off: Power supply OK; approx. +Vout (via 1k resistor - typ. 13.8V).
Off: Power supply OK; approx. +Vout (via 1k resistor - typ. 13.8V).
ON: Power supply failure; approx. -Vout (via 11k resistors - typ. 0V)
+ Remote – Not used for Paragon
- Sense – Not used for Paragon
-VE – main ground (0V)

3.1.6 Radio Backplane Assembly
A single PCB backplane is used. The main components are:
•
RJ11 connectors (J11, J12) – connects to the Speaker panel front RJ11. Used for program-
ming the Radio modules.
ming the Radio modules.
•
DB-25F port to ancillary equipement
•
One channel-select DIP switch (SW1)
•
Cooling fan driver – TB 3 located on backplane connects to the horizontally-mounted fan on
top of the Radio assembly and activated by BDLC’s PTT signal (setting JP1 2-3 will power
the fan continuously).
