i nstructions Feature This is a DMX512 decoder that specially designed for WS2801 and WS281 LED constant current driver IC It s easy to use and w iring Support s inputting DMX512 signal directly and execute internal pattern Supports a variety of DMX512 control equipment or 8~24V input voltage; W ith kinds of pattern When running internal pattern s each decoder can control 2048 pixels; Supports single and multiple synchronous Decoder a ppearance F ig.1 F unction s of each port: R ight side IN DAT+ DAT GND DMX512 input signal pole DMX512 input signal pole Ground O UT DAT+ DAT GND pole of DMX512 signal cascade to the next decoder pole of DMX512 signal cascade to the next decoder Ground CLK WS2801 c lock signal output DATA WS2811 and WS2801 s output signal GND Ground VDD The positive power supply Same as the chosen input voltage on the left side L eft side MODE Patter n switching SPEED S peed switching GND Ground Positive power supply 8~24V The positive power supply 8~24V +5V When clicked stands the power supply voltage is +12v/24V When clicked stands the power supply voltage is 8~24V N ote: The decoder s power supply voltage is optional,(can be changed internally, the method will be mentioned later please be sure that what the power supply voltage is selected then power the decoder.
8~24V Power Consumption less than Operating Instructions This decoder can work in two ways. Input the DMX512 signal or just running the internal patterns. Works without DMX512 signal Disconnect the DMX512 signal first and then power the decoder decoder will run the internal patterns. Pressing the key MODE to choose patterns from pattern to pattern and it will run your chosen pattern c yclically When running at pattern 51, it will jump back to pattern when pressing MODE,; Pressing the key SPEED to switch the running speed. There are levels of speed can be chosen, it will be slower each time pressing the key SPEED. When running at the s lowest level, it will jump back to the fastest level when pressing SPEED. While the decoder running in any pattern and speed pressing the key MODE and SPEED at the same time ,the decoder will jump to the pattern 0;(pattern is a pattern that run some patterns cyclically at a s pecific speed) Works with DMX512 signal Connect the DMX512 signal first, and then power the decoder. Using decoders in cascade When using the decoders in c ascade DMX512 signal will be decoded in each decoder at the same time, and display the same c ontent. 6.Power supply choice a nd choose 2801 or 2811 to be controlled When using this decoder, users can choose or 8~24V power supply to meet their requirement. Users can also choose WS2801 or WS2811 to be controlled. The methods are showed as the figure2 below. F ig.2
