NI488.2 throws an exception

[adityac26]

I am trying to control a temperature chamber using C# application via National Instrument .NET assemblies. My obversations are:

1.  Development Computer - Works PERFECTLY with Instrument. 

2.  Deployment Computer - (Installed NI488.2 + NIVISA drivers) - Throws an exception (see below) when executing my C# application

3.  Deployment Computer - (Using NIMAX - Instrument works perfectly) - I also double checked the port settings.

Versions used in Development Computer - NI488.2 (8.9.35.104)

Versions used in Deployement Computer - NI-488.2 2.24 + NI-VISA 4.1 + NI-VISA Runtime 5.0.2

Help please!!

You need to upgrade the GPIB drivers on the other machine.

Which computer? The deployment PC or the development PC? 

Also...it is the most updated NI-488.2 drivers. They have seemed to work well with other pc's. Is it because of labview runtime?

I dont really know what is the issue, it seems to be working just fine with all other PC's. The only difference is with the problematic PC has labview runtime installed which is the only unique property with every other pc.

What shall I do?

Hi,

You listed this for GPIB software versions

Versions used in Development Computer - NI488.2 (8.9.35.104)

Versions used in Deployement Computer - NI-488.2 2.24 + NI-VISA 4.1 + NI-VISA Runtime 5.0.2

The 8.9.35. 104 is the version of the .NET library.

The 2.24 is the version of the GPIB control software (DLLs)

Make sure that the deployment machine you're having problems with has a DLL version that's the same or higher than the development machine. 

Look under "Software" in NI-MAX.

Success!!

Turns out that the deployment machine's DLL for NI-488.2 was below 8.9.35. 104 version. Upgraded to newer DLL and it works! 

Thanks Curt!

Hi BrcT,

Do you also have a deployment and a development pc?  What version of the dll's do you currently have?

Thanks,
