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. If Cresnet HP is 
used for the same run, its length could extend to 1250 feet. 

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.  

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. 

For larger networks (i.e., greater than 28 network devices), it may become necessary 
to add a Cresnet Hub/Repeater (CNXHUB) to maintain signal quality throughout the 
network. Also, for networks with lengthy cable runs, it may be necessary to add a 
Hub/Repeater after only 20 devices.
