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)

Address 001 002 004 008
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. 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.
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.
