System Requirements

NI R Series Multifunction RIO software for the Linux/x86 64-bit architecture has been tested on the following distributions:

  • openSUSE Leap 15.2
  • openSUSE Leap 15.1
  • Red Hat Enterprise Linux 8
  • Red Hat Enterprise Linux 7
  • CentOS 8
  • CentOS 7
  • Ubuntu 20.04
  • Ubuntu 18.04

NI R Series Multifunction RIO 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 and enter the Info Code LinuxRepository.
  2. Download the installer for the repository add-on for your Linux distribution.
  3. Install the repository add-on using the rpm command.
  4. Select and install the following NI R Series Multifunction RIO driver packages through your Linux distribution's package manager:
    • ni-rseries

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.

Finding Examples

Examples are not installed on the system. To find examples, install the FPGA Interface C API on windows and use its examples. There are also Python examples online.

Linux Limitations

Some features discussed in the NI R Series Multifunction RIO documentation are unavailable on Linux.

  • NI R Series Multifunction RIO supports two application development environments:
    • C and C++ (gcc)
    • Python 3.5+
  • NI R Series Multifunction RIO does not support other ADEs, such as the LabVIEW Real-Time Module, LabWindows/CVI, Microsoft Visual C/C++, or Microsoft Visual Basic.
  • When using NI R Series Multifunction RIO in a PXI system, several restrictions apply:
    • Control through MXI-4 is supported
    • Control through MXI-3 is not supported
  • External calibration functions are not supported. Refer to your hardware documentation for information about external calibration, and refer to If your NI R Series Multifunction RIO requires external calibration, either perform the calibration on a Windows system, or hire NI or an independent calibration laboratory to perform the calibration.
