How do I use the digital I/O port?
You can use the Model 2651A digital input/output with the trigger model or to control an external
digital circuit, such as a device handler used to perform binning operations. To control or configure
any of the six digital I/O lines, send commands to the Model 2651A over a remote interface.
Use a cable equipped with a male DB-25 connector (L-com part number CSMN25MF-5) to connect
the digital I/O port to other Keithley Instruments models equipped with a Trigger Link (TLINK).

How do I trigger other instruments?
You can use the Model 2651A digital input/output to control an external digital circuit, such as a
device handler used to perform binning operations. For more information about the Model 2651A
digital I/O port, see
Another option is the Keithley Instruments TSP-Link
and communication bus that you can use to connect multiple instruments in a master and subordinate
configuration. See
Triggering a scanner
A typical test scenario might call for using the Model 2651A with a scanner to test a number of
devices under test (DUTs) in sequence. A basic example of this uses the Model 2651A digital I/O port
to trigger a scanner (shown in the figure below). In this example, line 1 of the digital I/O port is used
as a trigger output and connected to the scanner mainframe trigger input, and line 2 of the digital I/O
port is used as a trigger input.
