This file contains important information about the NI-HSDIO driver, including supported hardware, new features, a partial list of bugs fixed, and known issues.
If you plan to use LabVIEW NXG, refer to LabVIEW NXG Support and Considerations.
NI-HSDIO provides support for customers using NI digital waveform generators/analyzers. To program NI digital waveform generators/analyzers, use the NI-HSDIO API.
NI-HSDIO 19.5 supports the following operating systems:
1NI 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.
2NI 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.
Note Refer to NI-HSDIO Drops Support for Windows 7 (32- and 64-Bit), Windows Server 2008 R2, and All 32-Bit Windows Operating Systems in 2021 for information about future OS support.
Note In 2016 NI-HSDIO dropped support for Windows Vista, Windows XP, Windows Server 2003, and installations of Windows 7 without any service packs. NI-HSDIO 18.0 or later will not install or run on an unsupported OS. You cannot deploy or distribute applications that use NI-HSDIO 18.0 or later to an unsupported OS. Additionally, after installing NI-HSDIO 18.0 or later, you cannot use any installers built on this computer with any version of LabVIEW, LabWindows™/CVI™, NI TestStand™, or Measurement Studio on an unsupported OS.
For more information about the changes to our OS support for 2016, refer to Why Does My NI ADE Installer Fail on Windows XP/Vista and Windows Server 2003?.
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 ni.com/r/PAESupport.
NI-HSDIO 19.5 supports the following application software versions, including service packs. If you are not using NI application software, refer to Microsoft Visual Studio Support.
|Application Software||Versions Supported by NI-HSDIO|
|LabVIEW||2016, 2017, 2018, 2019, 2019 SP1|
|LabVIEW Real-Time Module||2016, 2017, 2018, 2019, 2019 SP1|
|LabWindows/CVI||2013 or later|
|LabWindows/CVI Real-Time Module||2013 or later|
|Microsoft Visual C++ (MSVC)||6.0 or later|
Note NI-HSDIO 19.5 does not support self-calibration of the NI PXIe-6556 with LabVIEW Real-Time Module. Use NI-HSDIO 15.0 and LabVIEW 2012 to perform self-calibration of the PXIe-6556 with LabVIEW Real-Time Module.
If you are using the NI-HSDIO .NET Class Library, .NET Framework 4.0 (minimum) is required. The NI-HSDIO .NET Class Library can be used with Visual C# or Visual Basic .NET in any Visual Studio version that can target .NET Framework 4.0 or .NET Framework 4.5.
To use the .NET API, you must install the .NET class libraries or the .NET wrapper in addition to the NI device driver. For information about versions of the .NET Framework and the drivers each supports, as well as the download location of the installer files, refer to National Instruments .NET Driver Support.
NI installs NI-HSDIO and other NI software using NI Package Manager. Visit ni.com/r/NIPMDownload to download NI Package Manager. Refer to the NI Package Manager Manual for more information about installing, removing, and upgrading NI software using NI Package Manager.
NI-HSDIO no longer installs IVI Compliance Package (ICP). NI-HSDIO supports IVI configuration and runtime, but no longer installs the following IVI components:
To use these features, you must install ICP separately. ICP is included in the Software Platform Bundle media. A stand-alone web distribution is available from ni.com/downloads.
The following list details which hardware models are supported in NI-HSDIO:
Note: Device-specific information about these modules is included in the NI Digital Waveform Generator/Analyzer Help.
NI-HSDIO 19.0 dropped support for Express VIs in LabVIEW. Existing code created with earlier versions of NI-HSDIO and that contains Express VIs will continue to execute, but the Express VI cannot be reconfigured from a dialog box.
To reconfigure an Express VI, right-click the Express VI and select Open Front Panel»Convert. This will convert the Express VI to code that you can configure on the block diagram. NI recommends converting Express VIs to code before using the Code Conversion Utility in LabVIEW NXG to convert code for LabVIEW NXG.
You can access the software and documentation known issues list online. Refer to the NI website for an up-to-date list of known issues in the NI-HSDIO.

The following sections detail considerations for using LabVIEW NXG with NI-HSDIO.
Software support for LabVIEW NXG differs in the following ways:
NI automates LabVIEW NXG installation using a package manager. Complete the following steps to install NI-HSDIO for LabVIEW NXG.
View context help in LabVIEW by pressing <Ctrl-H> and hovering over an object.
Search for items using the search bar in the upper right corner of the LabVIEW window. You can also view context help for the search results.
Additional documentation is available online at ni.com/manuals.
Launch LabVIEW and click the Learning tab.
LabVIEW lessons are located in the Lessons tab, and LabVIEW Examples are located in the Examples tab. Follow the instructions in the lessons and examples.
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. However, starting with the August 2012 releases (products using NI Installers version 3.1 or later), you may need to perform additional steps before or during a silent installation of NI software.
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:
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 ni.com/windows10.
When you install National Instruments software on Microsoft Windows 8.1, you will notice a few additional tiles in the Apps view, including shortcuts to NI application software products such as NI LabVIEW, Measurement & Automation Explorer (NI MAX), and NI Launcher. For more information about NI support for Windows 8.1, visit ni.com/windows8.
NI-HSDIO will drop support for Windows 7 (32- and 64-bit), Windows Server 2008 R2, and all 32-bit Windows operating systems starting in 2021. Versions of this product that ship after May 1, 2021, will not install or run on these operating systems. For detailed information about NI operating system support, visit ni.com/r/win32bitsupport.
