Model-based communications with Ethernet protocol

Ethernet is a low-level network protocol that interconnects computers and other devices in local area networks. It is the base-level network for other protocols, such as TCP and real-time UDP. For more information about the Ethernet standard, see

To communicate over a network with low-level (raw) Ethernet, use the Ethernet protocol blocks. The blocks connect to Intel® Ethernet boards that are compatible with PCI-standard bus architectures, such as PCI, PCI Express®, and PXI®. For detailed information about the Ethernet boards, see the manufacturer documentation.

See Model-Based Ethernet Communications.
