I seem to remember that GPO 1 is the bottom pair of pins...
please remind me which one the ground and which one the +ve is?
Ta...
Also if the pins are aligned thus (for example)
GPO3 Grnd
GPO3 Grnd
GPO2 Grnd
GPO2 Grnd
GPO1 Grnd
GPO1 Grnd
is there any difference between the top GPO1 and the bottom GPO1?
