NOTE: All Crestron certified Cresnet wiring must consist of two twisted
pairs. One twisted pair is the +24V conductor and the GND conductor and
the other twisted pair is the Y conductor and the Z conductor.
Strip and Tin
Wire
When daisy-chaining Cresnet units, strip the ends of the wires carefully to
avoid nicking the conductors. Twist together the ends of the wires that share
a pin on the network connector and tin the twisted connection. Apply solder
only to the ends of the twisted wires. Avoid tinning too far up the wires or
the end becomes brittle. Insert the tinned connection into the Cresnet
connector and tighten the retaining screw. Repeat the procedure for the
other three conductors.
Add Hubs
Use of a Cresnet Hub/Repeater (CNXHUB) is advised whenever the
number of Cresnet devices on a network exceeds 20 or when the combined
total length of Cresnet cable exceeds 3000 feet (914 meters).
