So i asked a question yesterday and today i got to know that it was my iPad 30 pin cable which is bad. can anyone help me with pin layout of positive and negative of the 30 pin connector and not the USB-A side side as i know that. I trued to google but i could not find the + and - Of the pin. if you can, please tell me the Data +ve and data negative too though i dont need it badly. Thanks.
