Sounds like you are reading it right. DMX was made for RS-485, wired communication. But companies do make wireless DMX. Since it is just lighting, the hope would be that if it did get a few bits messed up, they would come in correctly in the next 25 ms transmission. Microchip made this application note a while back. http://ww1.microchip.com/downloads/e...tes/01076A.pdf
