Hi guys!
Im trying to make my own download serial cable atm, and I've got hold of some old broken earphones which i plan to use as the download cable.
The problem is after removing the each of the earphones, I've got 2 wires (1 copper, 1 red) inside left earphone and other right earphone another 2 wires (1 copper, 1 blue). I will be soldering these wires to my 9Pin female connector, but heres the problem....
Im sure the copper will be GND as both contain the same copper wires. BUT which wire (red? blue?) goes to Serial In?out? If i took a random guess and hooked it up. Will the picaxe result in any major damage?
Thanks
