Yes, I used MAX. The GPIB card shows up there. So does the GPIB instrument. I tried to test the interface with the communicate with device button. The query just timed out. We un-installed the GPIB card and then re-installed it. We un-installed all LV programs and then re-installed LV6.1. Didn't work. The next morning I tried the run NI 488.2 Troubleshooting Wizard that you mentioned above. The Card & the interface tested out OK. So I tested our program again. Now it works. Hmmm. They didn't tell me it would be like this in school. I should have become an orthodontist. Everybody wants nice teeth...
