Thanks for choosing LT-830 DMX512 Decoder.
LT-830 RGB DMX decoding driver works to convert universal DMX512/1990
digital signal to PWM signal, Which controlled by DMX512 console, with 16-
bit gray scale output per channel. Realize 0-100% brightness or various
changing effect. And can control single color, RGB LED lights.

This decoder occupies 3 addresses, adopted Dip. Switch to set the
address, the Dip switches from 1 to 9 are a kind of binary value coding
switches used to set DMX512 initial address code, the correlative bits in
the 1-9 bits of the DIP switch, the 1st bit is LSC, the 9th bit MSC, 511
addresses totally 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.

Set the 1 , 3 , 6 , bit of the DIP switch downward to “1”the rest to “0”
(like figure 1), the summation from 1 to 9 is 1+4+ 32, so the DMX512 initial address
code is 37.

When decoder is at testing mode, DIP switch 8 is at “ON”, it is the 7 color jumping,
when DIP switch 9 is at “ON”, it is the 7 color smooth, with 8 speed levels for each

NOTE: According to DMX512 protocol, in order to ensure a steady DMX
transmission, you should weld a metalster (Metal Thin Film resistor，90-120Ω1/4W)
at the end of each layout of DMX data cable (between Foot 2 and Foot 3, Data + and
Data -), please also refer to your DMX console manual to select a correct resistor.
