3.1 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.

3.3 DMX Dimming Instruction:

Each LT-858 CC 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.
