DMX System Flow
DMX 512 control data from any standard DMX 512 console is output to the SHoW DMX
Transmitter, which converts that DMX data to a radio signal and broadcasts it to the
SHoW DMX Receiver (or Receivers). The SHoW DMX Receiver takes the radio
broadcast and converts it back into standard DMX 512 data, which can than be
connected via standard cables to SHoW DMX 5620 Dimmers or
any other
DMX devices
such as moving lights, effects, etc. A typical DMX system diagram is shown in the
drawing below

RDM System Flow
The SHoW DMX system also functions as an RDM Proxy system, by passing RDM
commands and replies back and forth between any connected RDM controllers and
responders. As with DMX, the principal thing to remember about RDM function is that
the Transmitter and Receiver(s)
replace
DMX cable. The main difference between DMX
and RDM operation is that RDM is a two-way system and so both Transmitters and
Receivers may need to function as wireless broadcasters or receivers of the RDM data.
In RDM mode, the SHoW DMX Transmitter converts incoming RDM commands to a
radio signal and broadcasts them to the SHoW DMX Receiver (or Receivers). The
SHoW DMX Receiver takes the radio broadcast and converts it back into standard RDM
data, then responds to it and/or passes it along to connected RDM responders, collects
any reply data from the RDM Responders, then converts the RDM responses back to a
radio signal which is broadcast back to the Transmitter. The Transmitter converts the
radio signals from the receiver back to wired RDM and sends it back upstream to the
RDM system manager, or may function as the RDM system manager itself. A typical
RDM system diagram is shown in the drawing below.
