3.2 USB Interface
Unlike RS232C, there are no generic drivers available as a rule for us in programming
environments such as LabView, LabWindows/CVI or Visual Basic. However, support for USB is
included under VISA and may be used to interface to the power source using the USB interface.
For other environments, a virtual serial port utility is provided on CD ROM CIC496 which ships
with the Lx/Ls Series power source. This utility will provide a virtual COM port on a PC under
Windows XP. This allows legacy programs to use the USB port as though it is a regular serial
port on the PC. The baud rate for this mode of operation is fixed at 460,800. If you plan to use
this feature, the USB-Serial Adaptor installation must be run to install the virtual com port driver.
This option is only supported under Windows XP / Windows Vista.
3.2.1 USB Driver Installation
When connecting the AC source through the USB interface to Windows XP/Windows Vista PC,
the presence of a new USB device will be detected. Windows will display a dialog after a short
delay prompting the user to install the USB device drivers.
On the CIC496 CD browser, select “USB-to-COM(WinXP/Vista32), select “GUI Software” tab and
click “Execute Selection” to complete the USB driver installation by selecting “Next”, “Next”,
“Install”, then “Finish”.
Close CD browser and restart computer.
This driver will allow access to the AC source USB interface using a virtual COM port. Many
programming environments support RS232 access but not USB. The USB-to-COM virtual port
driver is distributed on the CIC496 CD ROM.
