Thank you for using TestStand Wireless Test Module (WTM). This file contains important information about WTM and is organized into the following sections:
Product Security and Critical Updates
Automating the Installation of NI Products
Using NI Software with Microsoft Windows 10
Using NI Software with Microsoft Windows 8.1
WTM and TestStand provide a graphical user interface (GUI) for interacting with your Wireless Test System (WTS) instrument. Use WTM in TestStand to create and customize wireless connectivity tests for production and according to specifications. WTM is a framework that accepts device under test (DUT) and RF step plugins to perform any other wireless production test.
WTM 1.3 includes the following new features:
WTM 1.2 includes the following new features:
WTM 1.1 includes the following new features:
WTM 1.0.1 adds support for Bluetooth loopback DUT.
WTM supports the WTS instrument and instruments using the Wireless Test System Instrument Software (WTS Software). WTS-specific information is included in the NI Wireless Test System Specifications and Wireless Test System Getting Started Guide, available at ni.com/manuals.
Refer to the Recommended System Requirements section of the NI TestStand 2014 SP1 Release Notes, available at ni.com/manuals, for client PC requirements.
WTM 1.3 supports the following operating systems:
1 NI software installs VC2015 Runtime and .NET 4.6.1. Windows 8.1 requires 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 and Windows Embedded Standard 7 SP1 require Microsoft updates to support SHA-256. Refer to Microsoft KB3033929 for more information about how to install this security update.
Note WTM 1.3 and later does not support Windows Server non-R2 editions.
NI recommends that you have the most recent service pack for your operating system installed.
WTM 1.3 is supported in TestStand 2014 SP1 (32-bit).
The WTM installer installs all components required to deploy and run WTM on a deployment station, including the TestStand Base Deployment Engine. However, if you need to create or modify sequences, you must also install the TestStand development environment separately. The order in which you install TestStand and WTM is irrelevant.
NI recommends that you exit all programs before running the WTM installer. Applications that run in the background, such as virus scanning utilities, might cause the installer to take longer than average to complete.
Complete the following steps to install WTM.
Note You must have a valid TestStand 2014 license to develop or modify test plans with WTM. You can also run TestStand in Evaluation Mode to use WTM.
After you install WTM, you must use the NI Activation Wizard to activate the software or initiate the evaluation period for the software. You must have the serial number and the name of the software kit to ativate WTM. You can find both of these items on the Certificate of Ownership card included in your software kit.

WTM 1.0.1
| ID | Fixed Issue |
|---|---|
| N/A | Fixed an issue where an error occurred if the number format was changed from the U.S. number format using '.' as the decimal separator. |
| 551657 546854 | Fixed an issue where the components NI created for development and test purposes were available in the installer. |

Note To view PDFs, you need to have Adobe Acrobat Reader installed. You can install the viewer from www.adobe.com/reader.
Examples for WTM are located at Start»All Programs»National Instruments»WTM»WTM Public»Examples.
You can open example sequences and source code for the Operator Interface Example from the subdirectories of the <WTM Public>\Examples directory.
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:
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.
