Install Master Software Tools (MST) on the PC prior to connecting the BTS Master. MST provides the installation tool to install the USB and VISA drivers.
The Universal Serial Bus (USB) architecture is a high-performance networking standard that is considered “plug and play” compatible. The USB driver software is automatically detected and configured by the operating system of the devices that are connected to the bus. The MT822xB conforms to the USB 2.0 standard and is a USB “full-speed” device that supports data rates of up to 10 Mbps with the following restrictions:
• One USB network can support up to 127 devices
• The maximum length of USB cables between active devices is 5 meters (for USB 2.0) and 3 meters (for USB 1.0)
To run the following example, you must have NI-VISA 2.5 or later installed on the controller PC and you must select the VISA library (visa32.dll) as a reference in a Visual Basic project. For remote USB control, the controlling PC needs to have a version of VISA installed that supports USBTMC (USB Test and Measurement Class) devices.
1. Power on the MT822xB and controller PC and wait for the systems to power up completely.
2. Connect the USB cable mini-B connector to the MT822xB.
3. Connect the USB cable A connector to the controller PC USB host port. The controller PC should indicate “New Hardware Found” if the combination of USB VID/PID/Serial Number has never been connected to this controller PC.

USB Interface, Type Mini‑B
The USB 2.0 Mini‑B device connector can be used to connect the MT822xB directly to a PC. The first time the MT822xB is connected to a PC, the normal USB device detection by the computer operating system takes place. The CD‑ROM that is shipped with the instrument contains a driver for Windows 2000, Windows XP and Windows Vista. The driver is installed when Master Software Tools is installed. Drivers are not available for earlier versions of the Windows operating system. During the driver installation process, place the CD‑ROM in the computer drive and specify that the installation wizard should search the CD‑ROM for the driver.
