Hey guys, thanks for your answers.
@ice.durant7: I am not using it as a simulator. I want to connect with a car / cable with the DB9-Config. Since the default Pads are OBD2 it is not working right now.
@bill.yu: I want to put the arduino in a case and therefore use the build in connector / jack. I dont want to build in another jack.
Is there no chance? I thought ne pads are supposed to change the pin configuration on the connector?
Thanks a lot, greets,
Alex
