For example, Set initial address to 37:
As figure 2, set the 6th, 3rd and 1st bit of the DIP switch downward to “1”, the rest to “0”, the
total sum from 1 to 9 is 32+4+1, so the DMX512 initial address code is 37.
4. How to Set DMX Address via Dip Switch:
When FUN OFF, Decoder is DMX controlling mode, When FUN=ON, Decoder is self-test mode.

DMX512 initial address code is equal to the total amount of the Dip switches’ number from 1 to
9, press Dip switch downward(ON.: at position :”1”), user can get the number of its position, if
pressing upward(at position”0”), the number of its position is 0.

Welcome to choose our DMX decoder, DMX-SPI signal decoder works to convert DMX512 digital
signal to SPI (TTL)digital signal. It can control LED lights compatible with driving IC, and control
every channel of the LED lights, realize the function of 0~100% dimming or editing all sorts of
change effect.
DMX-SPI decoder are wildly 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.
