I tried to connect DAQpad 1200 to a NEC Direction SPL300 computer through parallel cable. The operation system is win2000. I followed the instruction on your web and verified the interrupt request (IRQ) setting (That means I already checked "Use any interrupt assigned to the port"). However, I still got the same message "the device is not responding to the first IRQ level". What could be wrong here?
If your parallel port DAQ device is not passing resource test even by selecting "use any interrupt assigned to the port", then I would suggest to verify that the parallel port is functioning properly by trying to use a printer attached to that port.
This will help determine if the problem is in the DAQ device or in the parallel port itself. Another way to verify this would be by installing the DAQ device in another system. Good luck with your application and hope this information is helpful.
