Using the Go-
NoGo Output
To output the Go-NoGo results to an
external device, the Go-NoGo rear
panel terminal (open collector) can be
used. The Go-NoGo terminal will
output a positive pulse each time a
NoGo violation has occurred for a
minimum of 500us. The voltage of the
pulse depends on the external pull-up
voltage.
