Dip Switch Operation:
3.
When Dip switch 1-9 are OFF, the defaulted .initial DMX address is 1
E.g.1: Set Initial Address To 32. E.g.2: Set Initial Address To 37. E.g.3: Set Initial Address To 178.
001+004+032=37 002+016+032+128=178

Value
3.1 How to set DMX address via dip switch:
DMX address value=the total value of (1-9), to get the place value when in “on” position,
otherwise will be 0.

[Attn] When several dip switches are ON, subjected to the highest switch value.
As the figure above shows, the br ightness will be 90%.
DMX Mode: The running light flashed fast when input DMX signal, the flashed frequency depends
on the frames of DMX master, if there is no DMX signal, the running light flashed normally.
