I need to create software for a GPIB instrument. I have the AT-GPIB/TNT ISA card and the NI-Device software package. Windows NT is running on a Aaeon 656 single board computer plugged into a passive ISA backplane with the GPIB card. I can install and run the NI 488.2 software fine, using the card as a controller. However, I need software for the card to act as a device. I uninstalled the NI 488.2 software and installed the NI-Device software. I get a HARDWARE_NOT_FOUND error when running the GPIBDevice sample code. Is the ISA AT-GPIB/TNT card compatible with NI-Device standard? If so, what could my problem be?
