The PCARD is used to program (PROG) and test the FRX2.
PROG features:
-Set the ignition sequence number 1 - 4
-Add FTX2 pairing (max. 8)
-Delete all stored pairings
In TEST position, the FRX2 is switched on - ignition is indicated with LED.
The PCARD does not care about polarity - it can be connected in either way on the FRX2.
