Terminating Jumper
Twisted Pair
Cable
HHNet connects controllers in series along a single twisted pair. Be sure to connect all the + terminals to
the same wire in the pair.
Note: The last controller along the net needs to have the terminating jumper installed. See above diagram
for location of jumper.
