Cable length planning guideline
You can connect Receivers directly to a Hub port connection or in a daisy chain to other
Receivers. Each Receiver receives 48VDC from the previous Receiver (or from the Hub, if it is
the first Receiver in the line) and passes the 48VDC on to the next Receiver in line via the CAT
5E cable. This CAT 5E cable also provides a clock source and serial communication to the
Receivers. An external AC adapter can power the Receivers but should only be required with
extremely long cable runs.
The maximum hub-to-receiver or receiver-to-receiver cable length is 1000 feet. This section
provides guidelines for cable lengths supported without the need for an external AC adapter.
