Hey Dbasnett, Kind of, i'll just reclarify incase.
It is similiar to MIDI in some ways of thinking.

So
-DMX is the protocal which has 512 Addresses (these are unrelated to time)
- Yes, each device/light will listen to it's assigned addresses, DMX itself has no idea what is listening though
- Yes, every 23ms or so, change or no change these are resent. This is the protocals 'Alive' check. However the timer i'm dealing with is seperate to this, as the driver won't allow me to hook into that frame as an auto check.
- Yes, each port can only carry 512 addresses. Then we move to what we call Universes. which i've seen upwards of 8 universes used on bigger events. However just starting with 2 working universes right now.
