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.

NOTE:
The CAMIDSPT requires a dedicated CNPWS-75 or a dedicated channel
of a C2N-SPWS300, both sold separately.
NOTE:
When installing network wiring, refer to the latest revision of the wiring
diagram(s) appropriate for your specific system configuration, available from the
Crestron website.
When calculating the wire gauge for a particular Cresnet run, the length of the run
and the Cresnet power usage of each network 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 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
R = Resistance (refer to the following table).
L = Length of run (or chain) in feet.
P = Cresnet power usage of entire run (or chain).
R <
L x P
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 following table.

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.
