kc64,
I would try to route a digital output line externally to an input line and check to see if the card is actually putting the digital output high. First make the physical connection and then run a test panel on the card and see if the input changes correspondingly with the output. If this fails, try other channels to see if the same behavior occurs. If this test passes, it implies that something could be wrong with your DMM or DC Voltage Measurement setup. I would also check if the DMM reads a known source correctly as well. Let me know if there are still problems after testing.
