    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)
