What cables are required to connect to ARCs?

A single standard straight-through CAT-5/6 cable will provide power and data to an ARC from the host DSP.  The daisy-chain to subsequent ARCs also uses CAT-5/6.

Legacy DSPs that pre-date the ARC Port (RJ-45) communicate to ARCs with a twisted-pair (A, B, Ground) for RS-485 data.  In this scenario a local external transformer provides up to 24VDC to the ARC.
