Patching a DMX light on a Behringer Eurolight LC2412 DMX console. Simple version.

Yes it's old. Yes there's probably only 4 of us and a chicken still using them. But if I needed a quick and concise to patching them, then the chicken does too. Here it is. In English. Quickly perform a 1 to 1 patch of an RGBW dmx lighting fixture.
One part. Under 2 minutes. The whole console visible. With absolute proof the advice works.
