NOTE:
For larger networks (i.e., greater than 28 network devices), it
may be necessary to add a Cresnet Hub/Repeater (CNXHUB) to maintain
signal quality throughout the network. Also, for networks with lengthy
cable runs or varying types of network devices, it may be desirable to add
a hub/repeater after only 20 network devices.
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
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.
