Dip Switch Operation:
4.
RDM Mode: The dip switch 1-10 are OFF.
FUN=ON (the 10th dip switch=ON)
Self-testing Mode:
FUN=OFF (the 10th dip switch = OFF)
DMX Mode:
Setting DMX addresses with dip switch 1-9
FUN=OFF (the 10th dip switch ) Mode=OFF DMX
4.1 How to set DMX address via dip switch:
E.g.1: Set Initial Address To 32. E.g.2: Set Initial Address To 37. E.g.3: Set Initial Address To 178.

5.1 Decoder can be connected to a variety of standard DMX512 devices:
*
at the end of each line.
If the recoil effect occurs because of longer signal line or bad line quality, please try to connect 0.25W 90-120Ω terminal resistor
*
An amplifier is needed when more than 32 decoders are connected, signal amplification should not be more than 5 times
continuously.

超过32台DMX解码器连接需加信号放大器，信号放大不能连续超过5次。
*
DMX解码器过多, 或信号线过长, 可用AMP接口放大信号, 连续放大次数请勿超过5次 当
*
当信号线较长或者线材质量等原因造成信号反冲效应影响使用, 可以尝试在每路信号线末端连接0.25W
