So, I understand the basics, I need computer with software to talk to controller who then talks to pixels. I need power to supply controller who then powers pixels and every 50 or so, I can inject power to next 50 or so etc etc to gain better light output. I have ws2811 string and strip, both will be talked to by Pixlite4 via either Xlite or Vixen3 software. now, each output on pix4, will handle upto 680 pixels, each with 3 ch's, (rgb)... Now I can count/label off 1 thru 680 with software, and these can be placed anywhere I want on my house ( provded they are within 6 or so mtrs), ie, 2 gutters and a gable, with a column on either side, total 680 pixels. and are controlled by software thru the controller on output 1. Software programmed to do what I tell the pixels to do.. ie, change color, on off and blink.... all these pixels can be on separate strings,so long as they all come back to output 1, via pig tails or daisy chain. out put 2 can do the same thing to a different area or to a set of mini trees. then same as 3 and then 4. DMX outlet, can then be used for Dumb rgb or just plain white or maybe a already bought Santa figure, to go on off, but NOT change color as the other outputs.
