Current Cost CC128, part 2

The CC128 rj45 pinout is like this, i.e.
1 = +v Unregulated (Same as the PSU input)
2 = PIC chip pin 52 (PGC)
3 = +V Regulated
4 = GND
5 = PIC chip pin 47 (PGD)
6 = PIC chip pin 9 (Program Voltage (nMCLR))
7 = Unit RX
8 = Unit TX

The stock RJ45-USB cable uses pins 1,4,7,8. I suspect you don't need 7 to just read the output of the meter, but you definitely need both 1 and 4.

Note to self: current setup

Input:
1 = 1 CC128
2 = 4 CC128
3 = n/a
4 = Phone
5 = Phone
6 = n/a
7 = 7 CC128
8 = 8 CC128
