Network Wiring
NOTE:
This section only applies to those applications using 4-wire Cresnet wiring.
When calculating the wire gauge for a particular network run, the length of the run
and the power factor of each network unit to be connected must be taken into
consideration. If network units are to be daisy-chained on the run, the power factor
of each network unit to be daisy-chained must be added together to determine the
power factor of the entire chain. If the network unit is a home-run from a Crestron
system power supply network port, the power factor of that network unit is the power
