How do I get GPIB USB-A to work in MAX 2.2?

[Brian Schneider]

I updated from LV 6.0 to 6.1. During the intallation MAX was updated to version 2.2. My problem is that my GPIB cark USB-A is not suported in MAX 2.2, I updated to 488.2 2.0 (W32) and I can now use my card within MAX again, but I cant use VISA aliases anymore. This is a problem since some of my older programs uses aliases for both instruments and COM ports. Is there an upgrade I can run or will I have to work without aliases?
Is it possible to uninstall MAX 2.2 and reinstall the old MAX from LV 6.0 and get it to work with LV 6.1?

Hope someone has a solution for my problem.

Fist I would suggest getting into contact with NI support on this issue. If in fact the card isn't supported by MAX 2.2 (I can't understand why that would be...), then you can uninstall everything, and reinstall LabVIEW 6, and upgrade to 6.1 WITHOUT updating MAX or NiDAQ.

You do not NEED Max to set up aliases.

Check with NI support about editing Visaconfig.ini (?).

The aliases end up in that file.

Found the answer 🙂 The solution was to uninstall all 488.2 and reinstall some older versions. The newer versions of 488.2 (1.7 and 2.0) didn't work well with my USB-A in MAX 2.2.

Thanks for the inpiration to the solution

You can find the file at C:\VXIpnp\WinNT\NIvisa\visaconf.ini

I have not experimented with creating new aliases from scratch but you can certainly save this file to perserve your aliases for the future.
