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.

Behavior Changes

In Windows Device Manager the detected serial ports will not list the serial number of the NI-Serial device to which they are associated. In NI-Serial Troubleshooter the list of verified serial ports will not contain the serial number of the NI-Serial device in the Port Description. The user can still use NI-MAX to associate the COM port numbers with their NI-Serial devices.

Accessing the Documentation

Refer to the NI-Serial documentation, accessible from ni.com/docs, for information about the NI-Serial.

Finding Examples

Select Help»Find Examples from LabVIEW to launch the NI Example Finder. LabVIEW examples for NI-Serial are located in the labview\examples\Instrument IO\Serial directory. You can modify an example VI to fit an application, or you can copy and paste from one or more examples into a VI that you create. NI-VISA is required in order to run NI-Serial examples.

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 4.6.2, 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 4.6.2 separately before you install NI software.

For more information about automating the installation of NI products, refer to Automating an Installer in the NI Package Manager documentation.
