Fixtures that support RDM?

All the intelligence is located in the DMX decoder which is where the RDM support is actually needed. There is no logic or intelligence in the analog LED strips that you would be able to get any info back from anyway.

Aha, so basically the DECODER reports the status of itself back to the ENGINE. BUT, if the decoder sends its PWM signals out the "analog" side (12v/24v), the fixture attached on the analog side obviously cannot report what it's doing since it's just regulating power to change colors, is that correct?

If that's the case, how can RDM report what it's doing if it really doesn't know how well the fixture is responding? For example, wouldn't it report inaccurate information if, say, there IS no fixture attached to the decoder?
