Hello, I now have a P2, Power Supply From Ray Wu 12VDC 350 Watt, and A strip of 5050, IC 2811, 150 chnls. My question is this: Should I Jumper K1 1-2, 3-4 and Leaving all others OPEN and power my strip from the power supply. It would be like the P2 video, set up but with 12V (7V - 40V) vice 5V. Would is this correct? When and why would I want to power my strip from the P2? Just want to learn as much as I can.
