If the recoil effect occurs because of long signal line or poor quality wires, please try to connect a 0.25W 90-120Ω terminal resistor at
the end of each line.
When more than 32 DMX decoders are connected, DMX signal amplifiers are needed and signal amplification should not be more than
5 times continuously. If you need to modify the parameter settings of connected DMX/RDM decoders that exceed 32, you can add 1 RDM
signal amplifier. Or you can add 1-5 DMX signal amplifiers after completing the parameter settings.
