DMX512 SPEC OF data format of WAVEFORM

[longpole001]

thanks for the info ,

As i am looking to use RF as the control , not a cable is it best to encapsulate the DMX512 protocol or go with a better protocol more in line with RF

Given your intended use ....

the payload is max 10 bytes and need to be sent about every 5sec so low data rates , just need to get there and accurate delivery

.... I would abandon any thoughts of using DMX. The baud rate is 250k and the data frame is intended to be repeated constantly.

Early DMX equipment didnt used to store the recieved values and any loss of the DMX signal would result in the lights going out. Modern equipment will retain the last values recieved.

For your application I would use a much lower rate like 9600 and implement some form of checksum. Even if you opted for 1200 baud you would still be able to send 120 bytes per second so your 10 byte packet could be sent 12 times per second.
