Hi I have a 12v adaptor to power my firewire hub connection between the laptop and the camera. It has a polarity option and I am not sure which polarity is correct - could someone help ?

If the camera is detected by the computer, then the polarity is correct. If the camera is not detected, you may change the polarity. The camera and the hub are protected against switched polarity.

Thanks for the confirmation on that Stefan. I just wanted to make sure I was not going to damage the camera.
