I have been to busy to play around with my ECG-P12R, until now. Finally got some projects done and now its time to start learning a new venture. I have read the paper that fast Eddy made, but worried about connecting power. I have ordered some 2811's from Ray and hope to have them next week, if the poor guy doesn't forget with the hundred other orders he has. On Page 9 of the guide, Connecting Power, it show many types of ways of hooking it up. It shows P13 & P00 have power in each one, and then different options. So here is my questions 1) If I just want to start it up and configure everything, and use a 12 volt, 20 amp power supply, can I just add the power to either P13 or P00 or do I have to have to both? 2) is it ok to update everything first in order to be able to use the 2811's or do I configure everything on the computer as if I was going to do the show? 3) I have a extra computer that is running XP that I was going to use just to play around with this, my main light show computer is Win 7, is it a hassle to add the to the show computer after, or is sort of a plug & play? I have read the manual a few times, but I must be missing something.
