4.1 How to set DMX address via dip switch:
FUN=OFF (the 10th dip switch =OFF ) DMX
DMX address value = the total value of (1-9), to get the place value when in "ON" position,
otherwise will be 0.
E.g.1: Set Initial Address To 32. E.g.2: Set Initial Address To 37.
001+004+032=37
4.2 Self-testing Mode:
FUN=ON ( the 10th dip switch = ON) Self-testing Mode
1-9=off 1=on 2=on 3=on

4.3 DMX Dimming Instruction:
Each LT-840 700 DMX decoder occupied 4 DMX -
addresses when connecting the DMX console.
e.g., the defaulted initial address is 1, please find
their corresponding relationships in the form.
