Thanks for the reply 'gcs'.
I tried to add the hardware however I encountered another problem. I installed the device however when I tried to 'Test Resources' using Ni-DAQ, the device did not pass the test. I believe it has something to do with the Resources values I entered: I/O Range, Interrupt Request, DMA, etc. Since I do not have my manual for the AT-AO-6, I do not know the correct values for these setting. If anyone can help me, please reply back.
Thank you
