The chart below describes the jumper settings for the ports. The jumpers are found on the MI100
interface board directly behind the I/O terminal strip.

When a combination of open collector and dry contacts is required, JP13, JP14, and JP15 should be
in position A (farthest from terminal strip), and JP16, JP17 should be in position B (closest to
terminal strip). This will provide 3 open collector outputs on terminal strip pins 1-3, and one
normally open dry contact on pins 4 & 5. Please note that the dry contact is rated for 1A Max
switching, 2A carrying for simple resistive loads up to 60VDC. Rated at 0.5A for 120VAC.
