We are planning to create 20x50 light matrix or maybe bigger. For light we will use light paper, which powered by 90-130v DC, but every peace has converter 12V DC to 90-130V DC. So i think it will be better choice to create all controlling with couple high power converters from 220V DC to 90-130V DC. I have one idea to use dmx, but it's limited to 1024 devices, also if I use this solution I can't create bigger matrix and it's not best choice for matrix controlling. Also if do with this solution I need to connect every light source to main station. Maybe it's easier to create matrix connection, but I don't know what controlling solution to use for this size and power of matrix. Maybe you can help me and offer how to controlling.
