System Requirements

NI-DMM software for the Linux/x86 64-bit architecture has been tested on the following distributions:

• openSUSE Leap 15.4
• openSUSE Leap 15.3
• Red Hat Enterprise Linux 9
• Red Hat Enterprise Linux 8
• Ubuntu 22.04
• Ubuntu 20.04

NI-DMM requires a 64-bit distribution and does not support 32-bit applications.

Installation Instructions

NI provides a repository add-on for all supported drivers that you can install using your Linux distribution's native package manager.

1. Visit ni.com/info and enter the Info Code LinuxRepository.
2. Install the repository add-on using the rpm command.
3. Select and install the following NI-DMM driver packages through your Linux distribution's package manager:
   • ni-dmm
   • ni-dmm-daqmx (for NI-DAQmx-based NI-DMM support)
   • [OPTIONAL] ni-dmm-devel (for C/C++ development support)
   • [OPTIONAL] ni-dmm-labview-20xy-support (for development support and examples on LabVIEW 2021 and earlier)
   • [OPTIONAL] ni-dmm-labview-support (for development support and examples on LabVIEW 2022 and later)

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.

The ni-dmm-labview-support supports applications using NI-DMM ​with LabVIEW 2022 or later. When installing NI-DMM, 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

Supported Hardware

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 Software Operating System Compatibility page. For historic driver and OS support information, refer to the readme for the relevant driver version.

Finding Examples

This release includes examples showing the use of NI-DMM in C and LabVIEW.

C examples are located in /usr/share/nidmm-devel/examples. Make files are provided that link to the necessary libraries.

The LabVIEW examples are located in the LabVIEW examples directory.

Linux Limitations

Some features discussed in the NI-DMM documentation are unavailable on Linux.

• NI-DMM for Linux offers API bindings for C/C++, LabVIEW 2020 and later, and Python.
  • For more information on installing and using Python, refer to the nidmm module.
• NI-DMM does not support other ADEs, such as the LabVIEW Real-Time Module, LabWindows/CVI, Microsoft Visual C/C++, or Microsoft Visual Basic.
• NI-DMM for Linux does not provide the following graphical configurations or debug utilities that are available for other operating systems:
  • Test Panels
  • NI Measurement and Automation Explorer (MAX) graphical configuration utility
    • The NI Hardware Configuration Utility is an alternative to discover and rename devices and is available with the ni-hwcfg-utility package.
    • Additionally, all supported NI-DMM hardware can be discovered and renamed through the NI System Configuration (NI-SysCfg) API.
    • Install the following:
    • ni-syscfg-runtime
    • ni-syscfg-devel (for C/C++ development)
    • ni-syscfg-labview-2021-support (for LabVIEW development)
    • Run the ./local/natinst/LabVIEW-2021-64/examples/nisyscfg/Rename Aliases.vi example to change aliases in LabVIEW
    • To read device aliases and general device properties directly from the command line, use the lsni -v or the lsni -u command.
• External calibration functions are not supported. Refer to your hardware documentation for information about external calibration, and refer to ni.com/calibration. If your NI-DMM requires external calibration, either perform the calibration on a Windows system, or hire NI or an independent calibration laboratory to perform the calibration.
• NI-DMM for Linux does not support remote debugging of applications.
• NI-DMM for Linux does not support Japanese localization for driver, LabVIEW application programming interface (API), and documentation.
