The required wire gauge should be chosen such that the resistance value

is less than the value calculated in the resistance equation. Refer to the

following table.

Wire Gauge Values

RESISTANCE

(R or Ohms)

WIRE GAUGE

(AWG) (MM

)

4 16 1.50

6 18 0.75

10 20 0.50

15 22 0.34

13 Doubled CAT5

8.7 Tripled CAT5

NOTE: All 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.

NOTE: 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.

NOTE: 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.
