For the electrically savvy MacGroupers: I have an OrangeLink Firewire PC Card that I use with a Powerbook G4 that has a dead Firewire port. In order to connect some devices that require Firewire power, I must connect an AC adaptor to this card. The manual says that I need an adaptor that meets the following specs:
Output 12V - 30V, 1 amp, positive tip. I have an adaptor that would fit the adaptor port on the Firewiire card, but its specs are: Output 12VDC, 1200 mA. There is also a symbol representing polarity that looks something like: _ _ _ ( - )-------( o -------( + ) (The two outside symbols are circles, the left one has a minus sign, the right one a positive sign. The middle symbol is a semicircle, with the right side missing.) My question: Would this adaptor work with my Firewire card? The only difference seems to be that this adaptor is 1200 mA rather than 1 amp. (I'm assuming that 1 amp = 1000mA.) I'm guessing that the symbols mean that the polarity is positive. What say ye? Would using a 1200 mA adaptor on a device that calls for 1000 mA work? Would it fry the device if I tried it? | The next meeting of the Louisville Computer Society will | be January 27.
