RS485 (DMX/RDM) Cable Terminations
Loop a shielded twisted pair cable (eg Belden 9841, though
many people now use a CAT5e cable) from the
control/monitoring point, around all enclosures.
Maximum total cable length is 1,200M (4,000ft). For longer
runs and wildly distributed systems, use a DMX/RDM
splitter (make sure that it supports RDM) and multiple
cable runs.
Use the termination switch to terminate each RS485 cable
run at the last enclosure on each run.
