NOW THAT i HAVE everything settled down are any of you using the FDS Master Caution and Sixpack unit? As you know I use Phidgets LED64, and the Leo Bodnar cards. The wiring from the FDS unit for LEDS only has 1 Grnd (common wire) the other 8 are for the leds. How did you connect it to the phidgets card which of course has a Hot and Grnd cable for each led. The switches of the card connect to bodnar but are not recognized either in FSX or FSUIPC, so how did you connect them? I will post the FDS wiring diagram. And as always a big "THANK YOU".
