CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do

so could cause equipment damage or void the Crestron warranty.

NOTE: When installing network wiring, refer to the latest revision of the wiring

diagram(s) appropriate for your specific system configuration, available from the

Downloads | Product Manuals | Wiring Diagrams section of the Crestron website

(www.crestron.com)

When calculating the wire gauge for a network run, the length of the run and the

power factor (power usage in watts) of each network unit must be taken into

consideration. If multiple network units are to be daisy-chained, the power factors of

each unit must be added to determine the power factor of the entire chain. The length

of the run in feet and the power factor of the run (in watts) should then be used in the

following resistance equation.

R = Resistance (refer to table below).

L = Length of run (or chain) in feet.

PF = Power factor of entire run (or chain).

R <

L x PF

40,000

Where:

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 table after this paragraph.

NOTE: All network wiring must consist of two twisted-pairs. One twisted pair is the

+24V conductor and the GND conductor; 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 network conductors.

Identity Codes

The TPS-RFGWX gateway/transceiver uses three forms of identification for

recognition within a Cresnet system and to communicate with a TPS-XTXRF or

STX-1700CXP touchpanel: Cresnet identity (NET ID), channel ID, and band. The
