Selecting an interface
The Keithley Instruments Series 2600 System SourceMeter
interfaces:
• GPIB (General Purpose Interface Bus)
• RS-232 interface
NOTE See
You can manually select the GPIB or RS-232 interface, or have the unit automatically select the
interface (the default) by using the COMMUNICATIONS menu accessed with the MENU key. The
unit can only be remote to one interface at a time. In auto-select, the unit will remote to the first
interface on which it receives a message. It will ignore the other interface until the unit is taken
back to local operation.
When the unit powers up, it will display the communication parameters of the selected interface. If
auto-selection is enabled, the unit will display the communication parameters of both interfaces.
GPIB operation
This section contains information about GPIB standards, bus connections, and primary address
selection.

GPIB standards

The GPIB is the IEEE-488 instrumentation data bus with hardware and programming standards
originally adopted by the IEEE (Institute of Electrical and Electronic Engineers) in 1975. The
SourceMeter is IEEE-488.1 compliant and supports IEEE-488.2 common commands and status
model topology.

GPIB connections

To connect the SourceMeter to the GPIB bus, use a cable equipped with standard IEEE-488
connectors, as shown in
11-2
Section 2 for more information on the GPIB and RS-232
communications interfaces. The TSP-Link is also a communications
interface. See Section 9
Figure 11-1.
