Hi all,
I have the Airbus RMP and transponder installed and working. But I can't find any documentation about the 2-pin jacks on the back of both units. There is also a jumper on the PC board? I am wondering if these are set up for external power to the backlighting? Maybe the jumper "on" will use 5v from the USB and jumper "off" is for 5v into the mysterious jack on the rear panel?

Does anyone know what is going on here?
