gonzo: yes thats the connector where to feed your bppc with power, but u need to be carefull! and a resistor would be nice to have on the cable also (maybe wrong name but its to keep the power signal at same rate)
i have 3-4 people around me who has this patch! , works fine! , but remeber 1 wrong wire...BOOM! ...your ppc is fried..
(12volt is a very bad thing , +5v is what you should power your bppc with)
cheers
ps: check the ESCOM A1200 thread , all info in that one about powering ppc directly.
pps:eyetech used to make and sell special cables for this.
