I have looked everywhere and cannot find any pictures with the JP4 plugged in, but i was told you have to use it to program the Coolrunner using LPT

Need to know what pin is + and what is GND...
I do not have the correct cable so i have to make my own.



From my Drawing does 1 = Positive and 2 = GND????
Also will it cause damage if I test positive and ground on either pin to find out which it is... (using 3.3v)
(Please excuse my butchered paint art)

Never mind I answered my own question just using a continuity tester. PIN 1 = GND and PIN 2 = Positive

I just hooked up a continuity tester from the VCC to PIN 2 and there is continuity meaning it has to be power :)
