If the only FireWire connections on your Mac are FireWire 800, here are some tips regarding compatibility of your FireWire 400 peripherals.
- FireWire 800 is backwards compatible with FireWire 400 devices. See this article on FireWire 800 technology for more details.
- You can use an adapter to connect Firewire 400 devices to a FireWire 800 connector. These adapters may be called "FireWire 400 to 800 adapter" or "FireWire 9 pin to 6 pin adapter". These adapters are available at the Apple Online store and at many computer supply stores. Most camcorders, audio interfaces, and other peripherals work equally well on a FireWire 800 port as on a FireWire 400 port. If you have any questions about the compatibility of your FireWire 400 peripherals with FireWire 800, consult with the manufacturer.
- If your system includes a mixture of FireWire 400 and 800 devices daisy-chained together, it's generally best to place the FireWire 800 devices closest to the computer in the chain.
