NI-VISA installation on Linux question

[vhelmont]

Hello,

We installed NI-VISA on a Linux pc running Red Hat 8.6

• A DELL pc
  • Pc hardware:
    $ cat /sys/devices/virtual/dmi/id/sys_vendor
    Dell Inc.
    $ cat /sys/devices/virtual/dmi/id/product_name
    Precision 344
• Redhat Version:
  $ cat /etc/redhat-release
  Red Hat Enterprise Linux release 8.6 (Ootpa)
• NI Linux Device Drivers (NI-488.2 and NI-VISA)
  • List enabled repositories in Linux:
    $ yum repolist
    ni-software-2022  ===> ni-rhel8-drivers-2022Q1.rpm
    
  • Installed ni-4882.2:
    /usr/lib/x86_64-linux-gnu/libni4882.so -> libni4882.so.21.5.0
    
  • Installed ni-visa:
    /usr/lib/x86_64-linux-gnu/libvisa.so -> libvisa.so.21.5.0

When I start NIvisaic with no instruments connected, I get (normal action):

When I start NIvisaic with an instrument connected to the GPIB bus, the program freezes:

The NIvisaic program is completely frozen, the Refresh button doesn't work and I have to kill the NIvisaic program.

Any help is appreciated on how to debug/fix this problem.

Regards,

Albert
