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.

Set the 4th, 7th, 9th, bit of the DIP switch downward to “1” the rest to “0” (as Figure 3). 

the summation from 1 to 9 is 8+64+256, so the DMX512 original address code is 328.

As figure, FUN=ON: test function: 1-9DIP switch =OFF: BLACK

1-7 is to set 8 speed levels.

7 is the fastest level, while dip switch 1-7=OFF: the speed is 0. 

As figure, the color changing mode is selected with a speed level of 7 when all the 

dip switches=ON.

For example: Set initial address to 37.

Example 2: set initial address to 328.

Specifications

DMX512 initial address code is equal to the total sum of the DIP 

switches numbered from 1 to 9, Placing the DIP switch in the 

DOWN position sets it’s value to ON. Placing the DIP switch in the 

UP position sets it’s value to OFF.
