Output characteristics:
• In addition to trigger events from other trigger objects, the digio.trigger[N].assert() and
tsplink.trigger[N].assert() functions generate a low pulse for the programmed pulse
duration if the line is latched low; a falling edge does not occur.
• A normal falling edge pulse generates when the internal drive is not latched low and the
digio.trigger[N].assert() and tsplink.trigger[N].assert() functions are issued.
• To mirror the SynchronousA trigger mode, set the pulse width to 1 µs or any small nonzero value.
• Action overruns are disabled.

Digital I/O
The 2600B has a digital input/output port that can be used to control external digital circuitry. For
example, you can use a handler that is used to perform binning operations with a digital I/O port.
Port configuration
The digital I/O port, a standard female DB-25 connector (shown below), is on the rear panel.
