I have the ADC-40 which was connected and working on a Compaq Deskpro running NT4.0 using both the Pico logging software (PLW) and a Visual Basic application.
The ADC module was removed and returned to the computer, but now both software applications say there is a 5v (127bit) constant from the module. They report this whether the module is plugged in or not.
Do you have any ideas on what is wrong. The PC has never had printer drivers installed.
I followed the instructions to turn off the computer and restart them plug in the ADC, no change.
