4. UP: Increase parameter key / preset parameter.

5. DOWN: Decrease parameter keys / preset parameters.

6. The AUTO PROGRAM mode is to repeat 7-32 part of the pattern or all of it. You can set whether to participate in the repeated loop operation in RUN TIMES.

7. RUN TIMES (run times): Compile the running times of the pattern in 34 AUTO PROGRAM mode. If the running times are 0, skip the pattern, that is, the pattern is not run.

8. Preset parameters: Each program has independent factory preset parameters, which are saved separately in the controller. LOAD DEFAULT (preset parameters) can restore the factory parameters of the program. If in AUTO PROGRAM mode, using LOAD DEFAULT (preset parameters) can restore all the parameters of the program to the factory parameters.

9, 33 ADJUST MODE is manual dimming, you can adjust the brightness of RGB 0-256 level.

10. 35 DMX512 MODE is to control all patterns (first address) and speed (second address).

11, 36 DMX512 DECODER is a DMX decoder, fully accepts external DMX512 signal work. Occupy three addresses, R (one address), G (second address), B (third address), need to set the address (PARA button to enter)

Note

A. is 110V/220V power input, the output high voltage 110/220 v article lamp directly. Article 110/220 v meet in the same line, at the same time electricity.

B. should be in strict accordance with the wiring. Red, green, black and blue four lines, the black line is the V+. Otherwise the color with the remote control signal may not to be relatively color or out of sync.
 
C. the quality assurance for two year. Artificial damage or misuse damage is not within the warranty.

D. can theoretically with the highest 5050-60 light RGB light 50 meters.(according to the measured, to achieve ideal control effect, suggested that connect 3528 RGB colorful lights with 50 m or 5050 RGB lights with 30 meters)

E. This products only is only available for high voltage RGB led strip lights.

 

Safety

Supply input voltage of this product is AC110/220V.

Shorting output wires my cause damage to dimmer.

Always observe proper polarity when connecting high voltage led strip lights and load.

For indoor use only - this product is not waterproof or weatherproof.
