I have updated this video with a step-by-step version as I made one for 2014
This is how I connected my 2 female jacks to the 27 channel DMX RGB controller board. I like the idea of an input output or a Y-splitter. This is how I did it so the controller receives commands from the computers DMX output.
i am new at this and I just want to know what controller I use for the singing Christmas tree quartet they take the m5 led mini lights can you help?
Sorry for the delayed response, I have been quite busy this year and missed your question. I recommend an AC type controller like the Light O Rama CTB 16 PC. They cost around $180 on sale.
