chained on the run, the Cresnet power usage of each network unit to be daisy-
chained must be added together to determine the Cresnet power usage of the entire 
chain. If the unit is home-run from a Crestron system power supply network port, the 
Cresnet power usage of that unit is the Cresnet power usage of the entire run. The 
wire gauge and the Cresnet power usage of the run should be used in the following 
equation to calculate the cable length value on the equation’s left side. 

Cable Length Equation 

L = Length of run (or chain) in feet
R = 6 Ohms (Crestron Certified Wire: 18 AWG (0.75 MM  ))

or 1.6 Ohms (Cresnet HP: 12 AWG (4 MM  ))

P = Cresnet power usage of entire run (or chain)

2

L <

40,000

R x P

Where:

 

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.  

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

 

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.
