Section 8: Digital I/O Series 2600A System SourceMeter® Instruments Reference Manual
Digital I/O port
The Keithley Instruments Series 2600A System SourceMeter
®
instrument has a digital input/output
port that can be used to control external digital circuitry. For example, a handler that is used to
perform binning operations can be used with a digital I/O port.
Port configuration
The digital I/O port is located on the rear panel and is shown in Figure 8-1. Note that a standard
female DB-25 connector is used with the digital I/O port.

Connecting cables
Use a cable equipped with a male DB-25 connector (Keithley Instruments part number CA-126-1),
or a Model 2600-TLINK cable to connect the digital I/O port to other Keithley Instruments models
equipped with a Trigger Link (TLINK).
Digital I/O lines
The port provides 14 digital I/O lines. Each output is set high (+5V) or low (0V) and can read high
or low logic levels. Each digital I/O line is an open-drain signal.
+5V output
The digital I/O port provides a +5V output that is used to drive external logic circuitry. Maximum
current output for this line is 600mA. This line is protected by a self-resetting fuse (one hour
recovery time).
