Thanks for choosing our LT-880 DMX512 decoder, LT-880 DMX512 decoder 

converts the universal standard DMX512/1990 signal into PWM signal to drive

 LED. It creates exclamatory, soft&perfect color fade effect by adopting special 

L-PWM program technology, which makes the LED more colorful and vivid.

Remark

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 correlative bits is the 1-9 

st

th

bits of the DIP switch, the 1  bit is LSC, the 9  bit 
MSC , 511 addresses totally.
DMX512 initial address is 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.

Example 1: Set initial address to 37

st

rd

th

Set the  1  , 3 ,  6 , bit of the DIP switch downward to 

1

the rest to 

0

(picture 2), the summation from 1 to 9 is 1+4+ 32, so the DMX512 initial address 
code is 37.
