3.7.3 USB Operating Protocols
The USB port on this product is a USB 2.0 port. It also complies with the USB Test and Measurement Class
Standard. Communications with this port requires the host computer to have a USBTMC driver available.
All commands and queries through this port must be terminated with a <CR>.
The cable required to make this connection is a USB 2.0 A-B peripheral device cable. The cable can be no
longer than 5 meters. If a longer distance is required a USB hub must be used. A cable carrying the official
USB logo is recommended.
When connected to a PC running Windows 2000 or XP a window will pop-up labeled Hardware Wizard. If
this PC has National Instruments LabView installed it will have a USBTMC driver that will work with this
port. This driver will allow the device to be easily controlled using National Instruments Measurement and
Automation Explorer or LabView. If a user wishes to write code in a different programming language, a
custom driver can be requested from AR. It should be noted that the USBTMC driver provided by National
Instruments is a VISA driver which can be used with other programming languages besides LabView. For
more information on this please consult the National Instruments Website found at www.ni.com
.
NOTE: All firmware updates are done through the USB port.
