Functional overview

RDM SPLITTER amplifier dedicated to DMX512 digital lighting control signal amplification. It's specially designed for connections of DMX receivers (Moving heads, color changers, dimmers, etc.) in a daisy chain configuration. It is suitable to the application that DMX 512 signal have been weakened because of long distance transmission. RDM SPLITTER CA-M28 will efficiently buffer. And magnify the DMX signal that makes the DMX data transmission more accurate and reliable.


  • RDM Splitter is a RDM and DMX signal superposition and separation manager
  • 2 DMX input and 8 DMX output
  • All the inputs and outputs are isolated. RDM Splitter can protect the operating DMX console and all the lighting when output error happens in any channel
    • 3 output modes:
    • a.)HTP mode DMX data from A port and B port, the higher DMX data is priority input
    • b.)LTP mode DMX data from A port and B port, the last DMX data is priority input
    • c.)Backup mode When there is no input form A port, B port will input DMX signal as backup port
    • 3 modes without output signal:
    • a.)Zero
    • b.)Hold data
    • c.)No DMX out
