DIGITAL I/O
111
Digital I/O Overview
Background
The Digital I/O port is a triple function port. By default
(Compare Mode) the port is used with the compare function to
output Hi Fail, Lo Fail, Pass, and EOM (end of measurement)
signals. In addition, there is also a TRIG IN input pin.
As a secondary function (4094 Mode) and third function (User
Mode), the Digital I/O port can have the output state of pins
5 ~ 8 controlled via remote control.
By providing separate VCC power for the terminal, the outputs
can also be used as a power source for TTL and CMOS
circuits.
