* The 3rd and 4th pins of DC IN connector are available only when the input/output switching setting is set to input.
Trigger signal polarity
Positive refers to a trigger signal polarity activated while rising from Low to Hi, or during the Hi interval. Negative refers
to a trigger signal polarity activated while falling from Hi to Low, or during the Low interval.
