Just to confirm few things before my parts arrive and start on this lovely project:


VCC - Red wire is from 1k Resistor
SIG - White wire is from 39k resistor
GND - Black wire is from “E” leg of both transistor and diode

and just wondering why kyosho's only have 2 wires SIG and GND?

Thanks.
That would be a cable for the new I.C.S USB adaptor. The USB one outputs fixed singal voltage (maybe 3.3v or 5v) to mini-z, and doesn't concern about what voltage of Mini-Z is, so only two wires are needed.

The old I.C.S. cable uses a diffrent way. It can "generate" various singal voltage according to opposite VCC.
ex. When PC sends a 12v signal through the RS232, this signal triggers the transistor to make the VCC of MINI-Z flow into the SIG line. So mini-z will get a signal that with the same voltage of it's own VCC. Voltage is been converted and meanwhile the signal is been transfered.
