Crestron C2N/C2NI-CB Series
Setup
Network Wiring
CAUTION: In order to ensure optimum performance over the full range
of your installation topology, Crestron Certified Wire, and only Crestron
Certified Wire, should be used. Failure to do so may incur additional
charges if support is required to identify performance deficiencies as a
result of using improper wire.
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 to help calculate how much power is
needed for the system (http://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 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 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 <
Make sure the cable length value is less than the value calculated on the
right side of the equation. For example, a Cresnet run drawing 20 watts
should not have a length of run more than 333 feet.
