To allow many parallel connections to one instrument, stack the connectors. Each connector has two
screws to ensure that connections remain secure. The figure below shows a typical connection
diagram for a test system with multiple instruments.
To avoid possible mechanical damage, stack no more than three connectors on any one instrument.
To minimize interference caused by electromagnetic radiation, use only shielded GPIB cables.
Contact Keithley Instruments for shielded cables.

Set the GPIB address
The default GPIB address is 18. You can set the address to any address from 1 to 30 if it is unique in
the system. This address cannot conflict with an address that is assigned to another instrument or to
the GPIB controller.
GPIB controllers are usually set to 0 or 21. To be safe, do not configure any instrument to have an
address of 21. To change the controller address, see the documentation for the controller.
The instrument saves the address in nonvolatile memory. It does not change when you send a reset
command or when you turn the power off and then on again.
