USB Interface Connection and Setup
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 instrument conforms to the USB 2.0 standard and is a USB “Hi‑speed” device that supports data rates of up to 480 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)
You must have NI‑VISA 2.5 or later installed on the controller PC and must select the VISA library (visa32.dll) as a reference in a Visual Basic project.
