CompactPCI® Serial • Quad Port USB 3.0 • Dual GbE

Option 8HP Front Panel w. RS-232 or CAN FD

The SBF-CROSSOVER is a peripheral slot card for CompactPCI® Serial systems, equipped with four individual USB 3.0 compliant controllers, and two Gigabit Ethernet NICs, all wired for front I/O. In addition, a PCI Express® Mini Card socket is provided on-board, which can be used e.g. for a fieldbus I/O module such as CAN FD. Furthermore, a quad port UART is available for RS-232 or RS-485 communication.

The SBF-CROSSOVER can be installed into any PCI Express® enabled peripheral slot of a CompactPCI® Serial backplane (PCIe® x4 or fat pipe slot recommended for optimum performance). All on-board devices are PCI Express® based. The front panel USB and Ethernet jacks are wired to individual controllers each, thus achieving the full data throughput on all connectors concurrently.
