DMX512 SPEC OF data format of WAVEFORM

[ScaleRobotics]

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

No, there is no checksum etc in the DMX-512 protocol itself but there are RF-modules which uses a more robust protocol so the DMX-512 frame you feed the transmitter will travel as payload inside a larger datapacket containing checksum etc and only come out of the receiver if the data is concidered valid. So, in short, it depends on what exactly it is you want to do and what type of RF-modules you're planning to use. The modules obviously would have to be able to handle
A) The bitrate and
B) Be able to handle packets of 513 bytes or more
