hp71 Card Reader Pinout (and CMT multi case connections)
Message #1 Posted by andy on 28 Feb 2003, 2:42 p.m.

I am looking for the hp71 card reader pinout. I know the following:

Pin 1: GND Pin 8: transmit data Pin 9: receive data

I have one of the CMT ruggedized cases and it has several connectors which clearly plug into the card reader pins. I'm trying to figure out which wires go to which pins.
