Magical DMX Distributor/Receiver (MDD/MDR) Backplane DMX Pinout
When tracing or replacing old DMX lines, it may be necessary to understand the pinout of the existing Magical DMX Distributor (MDD) and/or Magical DMX Receiver (MDR). Both products use the same backplanes with different pinouts. Below are diagrams of those boards with charted pinouts. Note that there are two versions of the board, identifiable by different part numbers and silkscreened copyright dates.
