NI-VISA 5.0 GPIB board not detected

[mtblanc]

Hello,

I have a long recurring problem with nivisa 5.0 on linux machine w/ kernel 2.6.32-21. I succeeded to compile (see my post http://decibel.ni.com/content/docs/DOC-13584) but the GPIB board is not detected.

First check that all the modules are incorporated in the Kernel

>lsmod | grep ni

>nipalk               1220783  3 NiViPciK

>nikal                  57338  1 nipalk

In python if I try to look up at the instruments through pyvisa

In[1]: import visa

In [2]: visa.get_instruments_list()

Out[2]: ['ASRL1']

Here is the visa version used:

Hello mtblanc,

Thank you for posting on NI forums.

To make things a little more clear, which kind of module/hardware do you want to use ?

If it is supported by NI-488.2, you may want to check this out : GPIB on Ubuntu.

Regards,

It looks to me like you have installed NI-VISA, but you have not installed the NI-488.2 driver. Both are required for GPIB communication through NI-VISA to function.

Dear Jason,

Yes I know the tutorial -actually I am the author of this tutorial, as well as more recent ones (DOC-13584)-. My problem is with recent version of nivisa(5.0)/ubuntu. It seems that the gpib card is not detected. There seems to be other post about it.

I was wondering what could be done to check the origin of the problem?

I shall mention that the mentioned conflict with gpib_common (thread above) is not, in my modest opinion, the real source of the problem. It should work and it has worked.

Installed nivisa5.0, kernel 2.6.32-21, gpib-linux 3.2.15

Cheers,

Olivier
