Mixing FireWire Speeds
Although FireWire 400 and FireWire 800 devices can be connected to the same FireWire bus via a repeater or
daisy chain, special precautions must be observed to maximize bandwidth in these situations.
FireWire 800 devices on a FireWire 400 bus
FireWire 800 devices are backwards-compatible and can be connected to a FireWire 400 bus using a 9-pin to
6-pin FireWire cable or adapter. However in this scenario any 800 megabit-capable devices on the bus (includ-
ing Apollo 16) will operate at a maximum of 400 megabits because FireWire bandwidth cannot exceed the
maximum bus speed of the host computer.
FireWire 400 devices on a FireWire 800 bus
FireWire 400 devices can be connected to a FireWire 800 bus using a 6-pin to 9-pin FireWire cable or adapter.
However, if the FireWire 800 devices are located after the FireWire 400 devices in the daisy chain, all FireWire
devices will operate at a maximum of 400 megabits because the FireWire 400 devices force all subsequent
devices to run at FireWire 400 speeds.
