Hello. In my time as a student we had a mobile DV/DVCam deck (DSR-xxx) to digitize DV material into an Avid. We learned the hard way that the proper procedure to connect computer and deck by Firewire, to switch both machines on, and then connect the Firewire cable, as if the other way around, the power surge will damage the Firewire port (4-pin) on the deck. Maybe it was only this particular model. Now at work we have a DV/DVCam/HDV deck by Sony, with a note to only attach the deck to a computer while the deck is switched off, but being connected to power. I recently rented the Panasonic AG DVX 100 AE camera, and the supplier told me to connect camera and computer (MBP in this case) when both are powered off. They couldn't answer me, if sleeping the Mac would suffice. But as my understanding of my students experience and little bit of knowledge about electric circuits, I would say, that the power surge by powering on the devices while connected could do more damage than both machines being already turned on and then connect them. Does anyone have an answer on how to properly connect DV decks/cameras and computers? And a technical answer I won't mind. I like to learn such things. Thanks in advance.
