No VISA Resources in Labview but all present in MAX

Go to solution



I am unable to find any VISA resources from LabVIEW, however, all NI hardware is available and working in MAX. I have just installed a PCI-8433/2 as well as a NI PCI-8512 CAN/HS Card. As part of the installation I believe MAX was upgraded to version 4.6.2. I will attach the max configuration report for those who are interested. I am working with LabView 8.2. I also uninstalled an agilent GPIB card and as a result the NI-GPIB card is the sole controller and is GPIB0... instead of the agilent card.



I have had a similar problem before that was a result of a corrupted database, but I was unable to find this problem on the forums this time and I am not getting any errors. Just an empty VISA Resource control.


Any suggestions would be greatly appreciated.

Take a look here


My guess is you wound up upgradeing vervions of NI-488.2.  the latest version does not have support for LabVIEW 8.20.  Upgrade to at least LabVIEW 8.5.1 of downgrade NI-488.2 2.7 available for download from here

Currently I have NI 488.2 version 2.46. Which is supported. Thank you for responding so quickly.

Now that IS odd.


Can you show a couple screen shots from MAX?


First expand the software tab and post a png of the screenshot (I'm not yet convinced you do not have SOME driver issue)


Next select MAX>TOOLS>NI VISA>VISA Options- Wait for the new screen Smiley Tongue then expand Mysystem General settings and select Aliases.


You could also try "Clear all aliases" from there and reboot.

Here is a screenshot of the MAX software list.



Thanks for your help...I fixed the problem. I had an agilent GPIB card previously. I disabled the tulip passport and cleared the aliases and refreshed MAX. Now my controls are populating properly.


Thanks again for your help!

Thanks to you too.  I had the same problem and disabling the tulip passport worked.  Not quite sure why this was a problem......but i'm happy with it just working...
