A standard USB Series B device connector is located on the rear panel for remote control. A standard
USB cable between the AC Source and a PC or USB Hub may be used.
Note: Use of the USB port to control more than one power source from a single PC is not
recommended, as communication may not be reliable. Use GPIB interface for multiple
power source control.
