    Hello, i'm trying to connect a gps module to a cf 28, trough the 50 pin port, just under the battery, but without the daughter board, i have a flat cable with the same "threading" of the original, with 50 pins, i connected the pin 37 to ground, then the bios recognize the gps and set it to auto, i connected the ground and the Vcc of 3.3 volt (yes i tested this voltage under load conditions), but now what is the correct pin to connect the serial NMEA coing out of the module ?

    I tried the pin 23 that on the scheatic is labeled as IN, i found this indication over this forum, but listening on the COM4 (correctly setted) i can't see any string.

    Maybe that is the 27 (labeled IN2) the correct pin ?
    Any suggestion will be greatly appreciated.
