I recently made a cable for my xmdirect.. it plugs in the serial port fine, and it plugs into the power connector fine.. but once I plug the cable into my XMD, the powersupply completely shuts down for like 30 seconds... I used a multimeter to match up the wires to the pins, and then I even double checked them after making my cable and they all seem to right...

what else could I possibly be checking?
