Check Network Wiring
Use the Right Wire
To ensure optimum performance over the full range of the installation topology, use
Crestron Certified Wire only. Failure to do so may incur additional charges if
support is required to identify performance deficiencies because of using improper
wire.
Calculate Power
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. Use the Crestron Power
Calculator to help calculate how much power is needed for the system
(www.crestron.com/calculators
).
When calculating the length of wire for a particular Cresnet run, the wire gauge and
the Cresnet power usage of each network unit to be connected must be taken into
consideration. Use Crestron Certified Wire only. 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 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.
