viOpenDefaultRM fails - why?

[mikieB]

viOpenDefaultRM is failing for me and returning a rather large value. What are possible reasons for this and what kind of things should I look at

[mikieB]

I should mention that this is my first time attempting to communicat over a GPIB/Ethernet converter box....I suspect that this *may* have something to do with it.

I get this error VI_WARN_CONFIG_NLOADED

Hi mikieB,

I need to get some more information from you.  What is the exact error you are getting?  What is the error code?  What versions of LabVIEW and VISA are you using?  Any more information about when you see this error or what's going on in your code would be helpful. 

Thanks!

Found the problem.

I was getting a configuration not loaded warning for the viOpenDefaultRM call.

Also a error(RSRC NOT FOUND) on the viopen call.

The problem was that the app was loading the 3.xx version of visa when I needed the 4.xx version.

Thanks for the help though.
