How DMX512 protocol da daisychain?
DMX is simply many RS-485 receivers on a single bus. They all can receive every byte on the bus. Some luminaries can take multiple IDs, for example an RGB lamp could take three IDs starting from the ID set to the lamp.
DMX can be bidirectional if the controller and luminaries support it, so there can be some kind of autoconfiguration going on. The protocol is called RDM.
RGB LED strips are not DMX, each RGB LED removes bits meant for it and passes the rest of the bits on to the next RGB LED.
