A couple of years ago I bought a Sweex PU005 parallel port card for my PC to give me a 2nd set of IO's
Whilst I installed it in the PC I never got round to using it as I had plenty of capacity on LPT1.
Now that I have run out of space on LPT1 I started connecting to it and have found, curiously, that all signal pins, except Pin 17 (?) measure 5v to the ground pins. It doesn't matter if I have pins 2-9 set as inputs the results are the same.
I have changed the port address to dff0 as per the View by Resource field in Device Manager but nothing changes, or is there a way to automatically find the correct adddress?
Any ideas?
thanks ...Sweep
