Okay, so I had some spare time to tinker with the Analog I/O card. Unfortunatelly I do not have much info now:
- On the DB50 connector on the bracket are signals from/to all the MUXes, this means 32 analog ports. Most probably analog inputs. The rest of the signals on the bracket connector is unknown.
- The card is electrically okay. It did not crash the computer I have inserted it in.
- the adressing uses only 10 bit, from which 7 MSB are to be configured by jumpers. This should help me to talk/listen to ports of the card.
