Network Wiring

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 | Software and Wiring
Diagrams section of the Crestron website (www.crestron.com).
When calculating the wire gauge for a particular Cresnet run, the length
of the run and the power factor of each network unit to be connected
must be taken into consideration. If Cresnet units are to be daisy-chained
on the run, the power factor of each unit to be daisy-chained must be
added together to determine the power factor of the entire chain. If the
unit is a home-run from a Crestron system power supply network port,
the power factor of that unit is the power factor of the entire run. The
length of the run in feet and the power factor 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 < L x PF
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 below.
