NI-DAQmx Base 3.2 sees PCI-6221 card, Labview doesn't

[mvanhorn]

We have a PCI-6221 in a Fedora 7. This worked with Labview 8.0 and NI-DAQmx 8.0, but the user now wants to use Labview 8.5. I have installed NI-DAQmx Base 3.2, and the install went fine and I can see the card listed with lsdaq; however, Labview still does not see the card. I assume there is something else I need to tell Labview to make it either search for the card or tell it how to find it directly, but I don't know how to do this.

Any help is greatly appreciated!

Hey Mike-

I think you might be running into the limitation that NI-DAQmx Base device and task names do not appear automatically in the LabVIEW controls.  Instead, you have to type those names in manually.

However, if you were already able to get NI-DAQmx for Linux working with Fedora 7, you may be able to just re-use the LabVIEW 8.0 NI-DAQmx VIs.

Hopefully this helps-

Okay, I am trying the latter (using the stuff from 8.0), but I can't get DAQmx 8.0 installed. I keep getting

error: Failed dependencies:
        nikali >= 1.8.0 is needed by (installed) nipalki-2.3.0-f1.i386
Error installing NI-DAQmx for Linux Installer Distribution 8.0.0f1.

I checked with yum, and nikali 1.8.0-f0 is installed, so I don't understand why it is giving me this message. Possibly related, I am seeing the following error message during boot in /var/log/messages:

Sep  8 13:13:25 medaq08 kernel: nipalk: no version for "nNIKAL100_unregisterPCIDriver" found: kernel tainted.

I seem to be missing some piece of software, but I'm not sure what.

Thanks!

Hi Mike-

I was under the impression that you already had NI-DAQmx installed and working.  A quick disclaimer- as you may or may not know, no Fedora distribution(s) are "officially" supported by National Instruments driver software.  So I can offer suggestions but not guarantees that you will be able to get it working.

Can you please run updateNIDrivers and post the output.  If that script returns successfully, please try the NI-DAQmx installer again and post the output.

Thanks-

Running updateNIDrivers didn't help. I eventually figured out, thanks to NI phone support, that we would have had to modify the kernel to get it working. Not an impossible task, but really not worth the effort, either. As the prof wanted Windows anyway, and was only using Fedora because the previous admin wanted it (who, presumably, had modified the kernel to get it working with the old versions of the NI software), we put Windows in the entire lab and everything worked.

Thanks!
