DMX-PWM CV DECODER
LT-854-5A DMX-PWM decoder works to convert universal DMX512 digital signal to PWM signal, which
controlled by DMX512 console. It can realize 0-100% brightness and various changing effect. And can
control single color, two color, RGB ,RGBA, RGBW LED lights.

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.
001+004+032=37 002+016+032+128=178
DMX address value = the total value of (1-9), to get the place value when in “on” position,
otherwise will be 0.

[Attn] When several dip switches are ON, subjected to the highest switch value.
As the figure above shows, the effect will be 7 colors smooth at 7 speed level.
For changing effects (Dip Switch 8 9=ON): /
DIP switch 1-7 is used to realize 7 speed levels.
(7=ON, the fastest level)

*
terminal resistor 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
*
An amplifier is needed when more than 32 decoders are connected, signal amplification should not be more than 5
times continuously.
