Recently came across this...
From Pathway Connectivity Inc. - DMX Vs DMX512... :
Mr. Ruling et al seem to have lost (or surrendered) the battle. Perhaps the new push is/should be to call it ANSI E1.11 - 2008 ? Thoughts?Members of ESTA's Control Protocols Working Group will generally complain if you don't refer to the industry standard lighting control protocol as "DMX512" and not simply as "DMX." You might wonder why...
...To help you remember, ESTA's Technical Standards Manager, Karl Ruling has penned this rap:
DMX Five Twelve is the name
Anything shorter just ain't the game.
Five-hundred twelve is how many bytes
That after the START Code lights your lights.
"DMX" is just a rapper,
A Microsoft group, a sunray zapper.
Add "five twelve" to get it right.
Go cue one! You'll see the light!
