In brief:
- Take apart the unit and remove the back-of-unit logic board.
- Attach power supply to AC to DC converter
- Solder wires onto back of DMX PCB
- Attach 3 of the ribbon cable wires (DIN, CLK, LOAD) to Arduino (11, 13, 5, respectively)
- Attach 1 of the ribbon cable wires (ISET) to power supply (with optional resistor to limit current - see [datasheet][AS1100] section 8.6)
- Ensure everything has a common ground (Arduino, power supply, DMX PCB, power converter)
- Download Arduino IDE and install required libraries (Adafruit_GFX and Code [manual install]).
- Copy example code to sketch and upload
- Profit?
