How can I visualize the VISA Is from an application VI?

Thanks for all the answers! I am a real rookie.

I found an old thread in this forum with my exact configuration, and they do say the iHR320 mono does NOT use VISA. I was unaware you could call a dll directly (as I said, real rookie!). How can I see which calls are being performed, with which parameters, etc?

Thanks for the recommendation, RavensFan! I'm going to try that. Will keep you posted.

That's why I said you need to open up those subVI's that are doing the work.  It would have shown the VISA calls (if they were doing that.)  Since they are not, they'll show the Call Library Nodes which do the calls to the .dll.  You can right click on them and check the properties.  You'll see the call setup for the inputs and outputs to the .dll.

Got it! In effect, I see now how DLLs are called. However, they don't seem to be installed as it always says "Method not valid for this class". That's not a problem, though, since I see what is being called and how. 

Thanks to all!
