12-2 Digital I/O Port, Output Enable, and Output Configuration Models 2500 and 2502 User’s Manual
Digital I/O port
The Model 2500 has a digital input/output port that can be used to control external digital
circuitry, such as a handler that is used to perform binning operations when testing limits.
Port configuration
The digital I/O port is located on the rear panel and is shown in Figure 12-1. Note that a
standard male DB-9 connector is used for the digital I/O port.
NOTE The four digital output lines and the SOT line are primarily intended for limit
testing with a device handler. See Section 11, “Limit Testing,” for details on per-
forming limit tests and interfacing to handlers and Section 10, “Triggering,” for
information on programming the Model 2500 to respond to the start-of-test
(SOT) pulse from a handler.
