Table 3-3: RS232 Connector pin out

The CSW series power sources use a regular straight-through DB9 male to DB9 female serial
cable for the RS232 interface.

3.6.4 USB Interface

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.
