15 is less than the 40 available so all the components CAN BE wired on a single
run from the a-2000 24 Channel cabinet without an additional external power
supply.
Power Wire - Run Length
The maximum total run length of each segment is a function of the total number
of unit loads. A run becomes to long when the voltage drop, due to wire size and
run length, increase to a point where the station does not have sufficient voltage
to operate. The maximum run length, in feet, based on the total number of unit
loads is shown below:

Terminating the wiring
Control Stations can be located up to 2,000 ft. from the dimming cabinet.
The 2,000 ft. limitation is a RS485 digital communications specification.
The power supply pair must be sized correctly for the control stations that
are connected to them.
Luma-Net is wired Daisy Chained, station to station. For applications where runs
become too long a Luma-Net Hub can be used. See Figure 15 for the correct ways
to wire this system.
