As I said in your previous post, unless Advantech has a VISA library for their card, you can't use any instrument driver based on VISA. VISA has been the standard for instrument drivers for many years and I don't understand why some GPIB board manufacturers don't provide it. Replacing the VISA calls in an instrument driver isn't difficult - just tedious. Of course, by the time you're done, the money saved on buying a less expensive GPIB board is more than offset by the money spent on paying you to do the conversion.
