What Is VISA? The Virtual Instrument Software Architecture (VISA) is a standard for configuring, programming, and troubleshooting instrumentation systems comprising GPIB, VXI, PXI, Serial, Ethernet, and/or USB interfaces. VISA provides the programming interface between the hardware and development environments such as LabVIEW, LabWindows/CVI, and Measurement Studio for Microsoft Visual Studio. NI-VISA is the National Instruments implementation of the VISA I/O standard.
NI-VISA includes software libraries, interactive utilities such as NI I/O Trace and the VISA Interactive Control, and configuration programs through Measurement & Automation Explorer for all your development needs. NI-VISA is standard across the National Instruments product line.
With NI-VISA, you can feel confident that your software development will not become obsolete as your instrumentation interface hardware needs evolve into the future. Also see: • • • •.

Your USB device is now installed and configured to use NI-VISA. Select your USB device to display the device information in the USB Settings window. Use this window to access information such as you device's manufacturer ID, model code, and serial number. USB Device Shown in MAX 2.
To communicate with your device using VISA, use your device's VISA instrument descriptor. The instrument descriptor format for a USB INSTR device is USB[board]:: manufacturer ID:: model code:: serial number[:: USB interface number]::INSTR. The instrument descriptor format for a USB RAW device is USB[board]:: manufacturer ID:: model code:: serial number[:: USB interface number]::RAW. According to the USBTMC specification, all USBTMC devices must have a serial number. However, some USB RAW devices may not have serial numbers. If your device does not have a serial number, NI-VISA automatically assigns a VISA specific serial number for that device. The format for the serial number is NI-VISA-#, where # is an automatically generated number.

Some USB devices have multiple interfaces. This is similar to how a PCI board can have multiple functions.
If your device supports only one interface, you do not need to include the USB interface number. The USB-6259 uses the RAW class, and the manufacturer code and model code are 0x3923 and 0x72A1, respectively. For the USB-6259, the instrument descriptor is USB0::0x3923::0x72A1::0125F0B3::RAW. To test communication with this device, open MAX. Select Tools»NI-VISA»VISA Interactive Control. A window similar to that shown in Figure 2 should open.

VISA Interactive Control 3. The VISA Interactive Control (VISAIC) is a utility program used to communicate easily with any VISA resource. After your USB device is configured to use VISA, it should be listed in the USB branch. Double-click on your device to open a VISA session to the device. The window shown in Figure 3 should open. VISAIC Open VISA Session When you open a VISA session with VISAIC, the Configuration tab and the USB Settings tab are automatically selected.
