Digital I/O Overview
The Digital I/O port is a dual function port. By default (Normal
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 (User Mode), the Digital I/O port can have
the output state of pins 1 ~4 controlled via remote control.
