Section overview
This chapter explains how to use commands for remotely controlling the Series 2200 instruments.
With this information, you can write computer programs to perform functions, such as setting the
controls, taking measurements, performing statistical calculations, and exporting data for use in other
programs.
The Commands listed in alphabetical order (on page 4-2) section provides detailed descriptions of
each command.
Communication interfaces
Your power supply has a USB 2.0 high-speed device port to control the power supply using the
USBTMC protocol. The USBTMC protocol allows USB devices to communicate using IEEE-488.2
style messages.
You can also remotely communicate between your power supply and PC over General Purpose
Interface Bus (GPIB).
Using the USB
Start by connecting a USB cable (Keithley Instruments Model USB-B - 1) between the USB 2.0 high-
speed device port on the rear panel of your power supply and a computer.
In order for the computer to recognize the power supply, a USBTMC driver must be installed on the
computer. A USBTMC driver can be installed on your computer by installing Virtual Instrument
Software Architecture (VISA), available for download from the Keithley Instruments website
(http://www.keithley.com).
Once the USBTMC driver is loaded, your computer will establish communication with the power
supply upon USB cable connection.
