Legal Information


NI-XNET is an NI instrument driver that features a common set of easy-to-use functions for reading and writing CAN, LIN, and FlexRay frames and signals in many different platforms including USB, PXI, PCI, NI CompactDAQ, and NI CompactRIO.

Supported Operating Systems

NI-XNET supports the following operating systems:

Note  Support for Windows 32-bit operating systems may require disabling physical address extension (PAE). To learn how this might affect your system and what actions you might need to take, visit and enter the Info Code PAESupport.

1 NI software installs VC2015 Runtime and .NET 4.6.2. Windows 8.1 and Windows Server 2012 R2 require Microsoft updates to support these items. Refer to Microsoft KB2919442 and KB2919355 for more information about how to install these updates.

2 NI software is signed with a SHA-256 certificate. Windows 7 SP1, Windows Embedded Standard 7 SP1, and Windows Server 2008 R2 SP1 require Microsoft updates to support SHA-256. Refer to Microsoft KB3033929 for more information about how to install this security update.

The NI-XNET installer does not support Windows Server 2003/NT/Vista/XP/Me/2000/98/95 or the Windows Server non-R2 editions.

NI-XNET does not support guest accounts on Windows 7. You must log into an administrative or user account to use NI-XNET on these operating systems.

Installation Instructions

Refer to the following instructions to install NI-XNET from a DVD. To install NI-XNET for LabVIEW NXG, refer to Installing NI-XNET for LabVIEW NXG.

Before installing the NI-XNET software, log on as Administrator or as a user with Administrator privileges. The NI-XNET software setup program must have Administrator privileges because the program modifies the configuration registry of your system. Complete the following steps to install the NI-XNET software.

  1. Insert the NI-XNET software DVD into the DVD drive. If the installer does not launch automatically, navigate to the DVD using Windows Explorer and launch the autorun.exe file from your NI-XNET software DVD.
  2. Click Install.
  3. The installation wizard guides you through the necessary steps to install the NI-XNET software. You can go back and change values where appropriate by clicking the Back button. You can exit the setup where appropriate by clicking Cancel.
  4. When the installation is complete, click Finish.

684951 Unaddressed J1939 Input Queue and Signal sessions do not receive data unless a stream session is also open on the interface.
685825 J1939 FIBEX databases that contain ECU names are not imported correctly, and saving the database will result in overwriting the name with 0.
687144 Extremely long strings passed to the XNET Create Session VI can cause LabVIEW to crash.
687562 Rev C (and later) PCI/PXI-8511 and -8512 devices might switch to Bus Off when attempting to transmit immediately following a reboot or Self-Test.

Additional Programming Topics

NI-CAN Compatibility

If you intend to use the NI-CAN API with your NI-XNET PCI/PXI hardware, refer to the NI-XNET Compatibility for NI-CAN appendix in the NI-CAN Hardware and Software Manual.

Deployed databases on LabVIEW Real-Time targets

When upgrading the NI-XNET software on your LabVIEW Real-Time target, you need to re-deploy your database files to that target using a host computer that runs the same version of NI-XNET as the target.

Removing and inserting C Series modules on CompactRIO targets during device communication is not supported

Inserting a module into or removing a module from a cRIO chassis that is actively communicating with an NI 986x module can cause application failures and possibly device damage.

Automating the Installation of NI Products

You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes.

If the NI product you are installing uses Microsoft .NET 4.0, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.0 separately before you install NI software.

For more information about automating the installation of NI products, refer to the following KnowledgeBase articles:

Using NI Software with Microsoft Windows 10

Microsoft Windows 10 is the latest version of the Windows operating system and features significant changes compared to previous versions. Windows 10 introduces several new capabilities and also combines features from both Windows 7 and Windows 8. For more information about NI support for Windows 10, visit
