JP8 (Digital Input Pull-high/low)
Jumper JP8 is used to set the Digital Input to either Pull-high or Pull-low, which allows the status of
the Digital Input to be predefined instead of remaining floating if the Digital Input channels are
disconnected or interrupted. Connecting pins 1 and 2 will set the Digital Input to Pull-high. To set
the Digital Input to Pull-low, pins 2 and 3 should be shorted. The default connected is Pull-low.
