Visit NI Hardware and Software Operating System Compatibility to view driver, desktop operating system, and real-time operating system support for individual hardware devices.
To view information for your device:
- Select your hardware model in the dropdown list on the page to view compatibility information for your device.
- Type your hardware model number in the dropdown list on the web page to filter the list of available devices.
Note: Some compatibility information may only be available in the archive attached to the NI Hardware and Operating System Compatibility page. For historic driver and OS support information, refer to the readme for the relevant driver version.
NI provides a repository add-on for all supported drivers that you can install
using your Linux distribution's native package manager.
- Visit ni.com/info and enter the Info Code LinuxRepository.
- Download the installer for the repository add-on for your Linux distribution.
- Install the repository add-on using the rpm command.
- Select and install the following NI-DAQmx driver packages through your
Linux distribution's package manager:
- ni-daqmx
- ni-daqmx-labview-version-support
After the driver package(s) are installed, you must rebuild the new packages for the system kernel. NI recommends that you run the command 'dkms autoinstall' after installation, and before rebooting the system, to install the latest revision of all modules that have been installed for other kernel revisions. After doing so, the installed device drivers will function immediately on the next system start.
Updated LabVIEW Compatibility Policy
The ni-daqmx-labview-support supports applications using NI-DAQmx with LabVIEW 2022 or later. When installing NI-DAQmx, this package will be recommended if you have already installed LabVIEW 2022 or later and installs to the LVAddons directory.
LVAddons directory location: /usr/local/natinst/share/lvaddons
