FW1

Dual-Channel, Tri-port per channel, for extended cabling up to 20 meters

The FW1 provides IEEE 1394 (Firewire) high-speed serial communications. The module is provided with a direct PCIe interface to the local (on-board) processor, or, an external host processor for board platforms that support external PCIe connectivity. These module(s) are not supported with the classic memory register-based NAIBrd Software Support Kit (SSK) API libraries. These communication function modules support device control and management via standard native OS (Linux) FireWire device driver.

IEEE 1394 devices are organized at the bus in a tree topology. Each device has a unique self-ID. One of the nodes is elected root node and always has the highest ID. The self-IDs are assigned during the self-ID process, which happens after each bus resets. The order in which the self-IDs are assigned is equivalent to traversing the tree depth-first, post-order.
