Can I connect FireWire devices to the ports on my PCI-324/424 card?
Only MOTU PCI Audio interfaces may be used with the PCI-324/424 card
While we use a FireWire cable to connect MOTU PCI Audio hardware to the PCI-324/424 card, we use our own protocol for communication called AudioWire. You can only connect MOTU PCI Audio interfaces to your PCI-324/424 card; FireWire devices, including MOTU FireWire Audio interfaces, cannot be connected to a PCI-324/424 card.
