LT-DMX-3001 DMX decoder works to convert universal DMX512 signal to SPI(TTL)
signal. It can control LED lights based on Tm1803, TM1804, Tm3001, TM1812 via DMX
console.
Tm1803, TM1804, TM3001 and TM1812 are the IC with grey scale processor. It can
support 256 scale levels and only need one signal cable, which convenient for design and
installation for the LED lights. These 4 chips are widely used in LED digital lights among
LED dot light, SMD strip, LED Fence tubes, LED wall light, LED pixel screen, LED Hi-
Power spotlight , flood light, etc.
The kernel of our LED controller adopt MCU from ATMEL to ensure the LT-DMX-3001 DMX
decoder runs steady.

1.This decoder adopts Dip switch to set the address. The Dip switches from 1 to 9 are a kind of binary
value coding switches which used for setting DMX512 initial address code, The 1st is the lowest one, The
9th is the highest one. Can set 511 addresses totally.
2.DMX512 initial address is the total amount of the Dip switch 1-9, down dip switch to “ON” position, User
can get its place value, Up dip switch to “OFF” position, Its place value is 0.

M1804, TM3001 and TM1812IC can choose high or low speed when used in LED
design circuit. TM1803 only can choose low speed. Designed in low speed will get
high PWM frequency and designed in high speed can control more LED lights. The
high or low speed choosing of the decoder needs to match the light’s design gears.
Otherwise the LED light can not work. The general LED lights are designed in low-
speed mainly.

The Decoder enter into DMX control mode automatically., when receiving DMX signal.
Like figure 1: Fun=off is high speed(upward), FUN=ON is low speed (downward)
