Overview
Rail-Demux is a DIN-rail or surace mounted device that converts DMX512 into 16 analogue
outputs. The standard that defines the output is ANSI E1.3 - 2001 (R2016).
DMX512 to analogue conversion has two key applications: upgrading older analogue dimmers
and driving fluorescent ballasts fitted with a 0-10V control facility.
The control interface uses DMX512 (all standards) and RDM or Remote Device Management.
The RDM interface allows the start address to be set by the controller over the DMX512 cable.
RDM also allows the product to receive firmware upgrades and run diagnostics tests.
DMX512 loop-through and termination options are provided. The product is powered via an
external DC power supply unit.
