Thanks everyone! I didn't realize that they actually have a document stating all the protocol for DMX 512. I went ahead and bought an electronic copy. Hopefully, I can understand it.

It's not going to be a stage lighting like you normally think of. It's actually going to be a fountain (http://mad-laborator...-stepper-motor/). I've been working on this project for too long, and am finally getting to the control part of it. I really want to be able to sync up the music and the fountain to "make it dance" so to speak. Ultimately I'm planning on getting a whole bunch of these installed in my yard. But let's not get ahead of ourselves here. I understand that DMX basically sends out an address and a value. If the slave device has been called then it looks at the value and act accordingly. Can a dmx device control two different devices? i.e. Can the netduino control the stepper and LED at the same time?
