RGB Pixel Mix 5V and 12V

[tbateson]

I currently am running 1,350 2811 Pixels using J1Sys P12R Controller and 2 5V Power supplies. I want to double that with Ray Wu 12V RGB Pixels.

Question is - can I connect: Computer -> J1Sys P12R Controller -> New undetermined 12V Controller, or do both Controllers have to be on separate nets? Wire diagrams and/or hints would be GREATLY appreciated.

the power supply has to be separate that's all. the controllers will go back to a network switch and that is really the only connection between the 2 controllers

The data signals for all pixels is 5V regardless of whether they are 5V or 12V. As long as you keep the positive supply separated from the 2 you can actually chop and change 5V and 12V pixels on a given output. The 0V line has to be common across the power supplies.

Welcome to ACL by the way

There are drawings in the ACL 101 lighting manual that should show this

Most controllers have 2 banks for power so you can use 2 different voltages. You can also uses different voltages within the same output/string as all you need to do is ensure the +V is not connected between the supplies and string, but the ground (-V) is connected between the power supplies/strings
