Network Wiring

CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to
do so could cause equipment damage or void the Crestron warranty.
CAUTION: Provide sufficient power to the system. Insufficient power can lead to
unpredictable results or damage to the equipment. Please use the Crestron Power
Calculator (www.crestron.com/dealer-tech_resources/power_calculator.asp) to help
calculate how much power is needed for the system.
CAUTION: Possible equipment damage if miswired.
NOTE: When installing network wiring, refer to the latest revision of the wiring
diagram(s) appropriate to your specific system configuration, available from the
Downloads | Product Manuals | Wiring Diagrams section of the Crestron website
(www.crestron.com).
NOTE: Do not power up system until all wiring is verified. Care should be taken to
ensure data (Y, Z) and power (24, G) connections are not crossed.
When calculating the wire gauge for a particular Cresnet run, the length of the run
and the Cresnet power usage of each Cresnet unit to be connected must be taken into
consideration. If Cresnet units are to be daisy-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 a 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 length of the run in feet and the Cresnet
power usage of the run should be used in the following resistance equation to
calculate the value on the right side of the equation.
Resistance Equation
40,000
R <
L x P
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.
