Now back to the DMX, yall both helped me understand what it is, but I just wanna check, the lightboard doesnt run straight into the dimmers, it runs into a DMX first correct?

And the DMX allows the board to communicate with the dimmer telling which dimmer to come on at what percent. right?
DMX is not a thing, it is a communication protocol, or a "message" that is "written" in a particular "language". If you are familiar with MIDI, think of it as similar to that. The lighting console sends out a signal - a message that is written in the DMX language. This DMX signal is fed via DMX cable (basically like mic cable with less capacitance) into the dimmer pack (or LED PAR or moving fixture), which reads the message and interprets what instructions it is being given in this message. It then carries out the instructions. For a dimmer, the message might be "fade channel 3 up to 50%". For a moving fixture, the message might be "change color to gel holder 2, then fade up to 100%, then simultaneously pan 45 degrees clockwise and incline 90 degrees".
