NOTE: According to DMX512 protocol, in order to ensure a steady DMX data
transmission, you should weld a metalster (Metal Thin Film resistor，90-120Ω1/4W)
at the end of each layout of DMX data cable (between Foot 2 and Foot 3, Data + and
Data -), please also refer to your DMX console manual to select a correct resistor.
5. Attention
1. The product shall be debugged and installed by professional persons.
2. This product is non-waterproof, please avoid the sun and rain. Put it in a water- proof box if
install outdoor.
3. Good condition of heat dissipation will prolong the working life of controller, please install the
product in a good ventilated condition.
4. Please check if the output voltage of the LED power supply comply with the voltage range of
the product.
5. The diameter of adopted cable should load enough connected LED light. Ensure a solid
connection in order to avoid triggering accident result from poor contact or cable overheat.
6. Ensure all wire connection are correct before power debugging, which is to avoid lamps to be
burnt because of wrong connection.

Remark
This decoder occupies 3 addresses, adopted Dip. Switch to set the
address, the Dip switches from 1 to 9 are a kind of binary value coding
switches used to set DMX512 initial address code, the correlative bits in
the 1-9 bits of the DIP switch, the 1st bit is LSC, the 9th bit MSC, 511
addresses totally 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.
Example1: Set initial address to 37
Set the 1 st , 3 rd, 6 th, bit of the DIP switch downward to “1”the rest to “0”
(like figure 1), the summation from 1 to 9 is 1+4+ 32, so the DMX512 initial address
code is 37.

Example 2: Set initial address to 328
Set the 4 th , 7 th, 9 th, bit of the DIP switch downward to “1”the rest to “0”
(like figure 2), the summation from 1 to 9 is 8+64+ 256, so the DMX512 original
address code is 328.

When decoder is at testing mode, DIP switch 8 is at “ON”, it is the 7 color jumping,
when DIP switch 9 is at “ON”, it is the 7 color smooth, with 8 speed levels for each

the color changing function, DIP SWITCH 1-7 for the speed function, comply with
the largest value switch, SPEED 7 is the fastest speed.
