1. Set DMX512 Original Address:
DIP 1
2 3 4
Address 001 002 004 008
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.
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.
