Quad OHCI IEEE 1394b (Firewire 800) to PCI Express x4 Gen2 Host Card
The FWBX4-PCIE4XE120 is a Quad OHCI IEEE 1394b (Firewire 800) to PCI Express x4 Gen2 Host Card.
FWBX4-PCIE4XE120 is designed with two key components.
MultipleVCs (Virtual Channels) on the PCI Express link provide native support for QoS (Quality of Service) transmission for real-time and multimedia applications in a standards-based framework, ensuring compatibility with current and future operating systems. Active-state power management allows dynamic power management during periods of reduced network activity.
