I have an application that uses the USB-8451 OEM board. This uses SPI to read voltages off and A/D converter. My counterpart at our production facility has purchased the non-OEM version of the USB-8451 (boxed version). He tried this in the same application but when reading the A/D converter he gets all zeroes instead of the proper voltages. I believe he has connected the boxed version properly. So the question is why do these work differently? Is there something I need to do in the software to account for the difference? I am using CVI 6.0.
