The Galil 1840 series usually has 8 inputs 8 outputs on its own, unless you have an expansion card,
Mainly the I/O is through the PC Contec card for the extra I/O.
I once had a similar experience with the Galil/Camsoft drivers etc getting the same message 'register the card'. I spent many, many hours trying new computers with clean install and talking to Camsoft support, never did solve the problem with this particular card.
The card ran fine with Galil software.
In the end I sold the whole system.
