I developed a LabVIE

[ACJ]

W6.1 application on a laptop running Win2K. Hardware interface is GPIB-USB-A. The program works great. When I install the application on a comupter with any other kind of GPIB interface it does not work as well. I get timeouts and other strange behavior.The problem area is the VISA Wait on Event Async.VI It timesout. Are there some setting that I need to change on the none USB GPIB interfaces.

What other interfaces have you tried? If the other interface happens to be the GPIB-232CV-A you should be know that particular interface does not assert the EOI line. What event are you waiting on? It would also be very helpful to run NI-SPY to see what commands are being sent.
