Ltech LT-854-5A Quick Start Manual

LT-854-5A
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.

Value

4.1 How to set DMX address via dip switch:

FUN=OFF ( the 10th dip switch =OFF ) DMX
DMX address value = the total value of (1-9), to get the place value when in "on" position,
otherwise will be 0.
E.g.1: Set Initial Address To 32. E.g.2: Set Initial Address To 37.
001+004+032=37

4.2 Self-testing Mode:

FUN=ON (the 10th dip switch=ON ) Self-testing Mode
Dip Switch 1=ON 2=ON 3=ON
1-9=OFF

[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.
