Make sure the cable length value is less than the value calculated on the right side of the
equation. For example, a Cresnet run using 18 AWG Crestron Certified Wire and drawing 20
watts should not have a length of run more than 333 feet (101 meters). If Cresnet HP is used for
the same run, its length could extend to 1250 feet (381 meters).
NOTE: All Crestron certified Cresnet wiring must consist of two twisted pairs. One twister
pair is the 24 and G pair and the other twisted pair is the Y and Z pair.
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 (
) 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).
