LT-DMX-1809 converts the universal standard DMX512 signal into SPI(TTL) digital signal to drive LEDs with compatible driving IC, it could control every channel of the LED lights, realize 0~100% dimming or editing all sorts of changing effect. DMX-SPI decoder are widely used in LED flashing word string light, LED dot light, SMD strip, LED digital tubes, LED wall light, LED pixel screen, Hi-power spotlight, flood light, etc. 1. Product Parameter: LT-DMX-1809 The Decoder enter into DMX control mode automatically when receiving DMX signal. Like figure upward: FUN=OFF is high speed(upward), FUN=ON is low speed (downward) 1. The driving chip of this decoder has option for high and low speed(800K/400K), please choose the suitable speed according to the design of your LED lights, in most cases, it is high speed. 2. 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. E.g.3: Set Initial Address To 178.

Input Signal: DMX512 Input Voltage: 5~24Vdc Output Signal: SPI Decoding Channels: 512 Channels/Unit Dimming Range: 0~100% Working Temperature: -30℃~65℃ Dimensions: L125×W64×H40(mm) Package Size: L135×W70×H50(mm) 4.2 Self-testing Mode: 001+004+032=37 002+016+032+128=178

DMX512 Socket: XLR-3, Green Terminal Weight (G.W.): 300g When no DMX signal and FUN=ON (the 10th dip switch=ON) Self-testing Mode Compatible with WS2811/2812 UCS1903/1909/1912/2903/2909/2912 TM1803/1804/TM1809/1812 driving IC) Dip Switch 1-9=off 1=on 2=on 3=on 4=on 5=on 6=on 7=on 8=on 9=on

2. Configuration Diagram: Self-test Function Static Black Static Red Static Green Static Blue Static Yellow OFF Static Purple Static Cyan Static White 7 Colors Jumping 7 Colors Smooth

Static Green Static Yellow Static Cyan ON 7 Colors Jumping For changing effects (Dip Switch 8/9=ON): DIP switch 1-7 is used to realize 7 speed levels. (7=ON, the fastest level)
