LV 2011 install, VISA quit working

Solved!
Go to solution

I've been using LV2010 since it was released on a project. Everything worked great. I installed LV2011 Friday

and the PNA I'm using quit responding. Its like its not even in the system.

 

I upgraded to LV2011 on a different project and the PNA worked fine afterwards.

 

The error message is something like "Device not present or insufficient location information".

 

I double checked the address string and went over all of the code. It is exactly as it was before I

installed LV2011.

 

Also on a side note... I tried the project in LV2010 (from a backup) and now it doesn't work either. I'm guessing LV2011

overwrote something?

 

I can't post any code, but I'm using the Phase III VI library (I don't remember where I got it, maybe it came with the network analyzer).

That shouldn't be a problem though because the code fails on the 'Open Visa' primitive.

 

Any ideas?

Were you using an alias for the device, or a full resource location? If you were using an alias have you verified the alias is there in MAX? You could try recreating the alias.

 

Did you try performing a repair on the NI-VISA installation, or simply uninstalling and reinstalling it? That sometimes fixes these kinds of issues.

 

What interface are you using? Serial, GPIB, TCP/IP?

Full resource location (ie: "TCPIP0::192.168.100.40::hpib7,16::INSTR").

 

The device does not show up in MAX and I have reinstalled NI-VISA. GPIB (as you can see from the location).

 

I suppose I should have reinstalled LV2011 before posting here. That may fix it. I thought that maybe someone else

has had the same issue.

Glad to hear! This fix will go into the next released version of NI-VISA, which we're targeting for later in Q1 this year. Keep in mind that date is tentative and subject to change.
