FIBER CONNECTION
The optical connection is made via a ST connector located on the right side of the unit.
CONTACT CLOSURE INPUT AND OUTPUT CONNECTIONS
Contact closure input and output connections are made via terminal blocks attached to the right side of
the unit. Please note that the two Channel 1 inputs begin at the second terminal screw closest to the
fiber connection on each of the two nine pin terminal strips. Channels 2 through 8 connections continue
down the terminal strip. For optimum performance the copper cables carrying the contact closure signal
should be the shortest length of wire practical. See drawing below for contact closure connections.
