To minimize interference caused by electromagnetic radiation, use shielded GPIB cables, such as
the Keithley Instruments Models 7007-1 and 7007-2.

GPIB standards
The GPIB cable is the IEEE-488 instrumentation data bus with hardware and programming standards
originally adopted by the Institute of Electrical and Electronic Engineers (IEEE) in 1975. The 4200A-
SCS conforms to these standards:
• IEEE-488.1-1987
• IEEE-488.2-1992
Ethernet connections
Use a standard cable (CAT-5, RJ-45 terminated) to connect to the 4200A-SCS, as shown in the
figure in Communications connections (on page 9-2
).
Using KCon to configure KXCI
You use the Keithley Configuration Utility (KCon) to configure KXCI. Use KCon to select and
configure communications (GPIB or ethernet) if you are using 4200A-SCS as a remote instrument. If
you are using 4145 emulation, you use KCon to assign source-measure functions to the installed
SMUs.
For details on KXCI that are set through KCon, refer to Keithley Configuration Utility (KCon)
(on page
7-1).
Before opening KCon to change the present KXCI configuration, you must close KXCI.
The presently selected communications interface (GPIB or ethernet) and its settings are displayed in
the KXCI console. The command and message area below the KXCI settings displays sent
commands, KXCI error messages, and numerical test results (refer to Using KXCI (on page 9-6
)).
