My computer device manager finds the gpib card and driver, but labview will not communicate with the card.
I run MAX software and on the Comm 1 I get an open visa test panel icon. when I select GPIB I do not get this option.
I cannot get any VI to control the GPIB card . What have I done wrong??

This makes no sense.
Generally the purpose is to control an instrument connected to the GPIB card.

I agree. Ok I am trying to control a BK Precision model 9201 power supply. I have even tried a Agilent 34401A DMM . LabVIEW provides that as an example of an instrument driver. Both with different GPIB cables and I have loaded the drivers for them.
Usually when I have seen communication occur on other projects over GPIB the display on the device will show that communication is going on between the computer and the device. on this I see no response on any device.
I must also say that this project has the real time module loaded and from my searching of material I have read that this module does not like VISA communication because it interferes with the real time processes.

I have no experience with LabVIEW real time. Hopefully someone who does can answer or you can contact NI if you have a SSP contract with them.
