I am a bit confused how to connect power to the P12R. I have the instruction manual and on page 9 there are various options on connecting power. Before I fry anything I thought I would just check with you good folks. I have a 12V power supply which I want to run the outputs on both sides of the board. So, do I just connect power to the K1 terminal with the GND to the right hand side (where is says GND) and the positive to the left hand connection? The part that confuses me is that none of the pictures seem to emulate how I think they should be connected.
