Characteristics Of Automotive ETHERNET
The Automotive Ethernet network is being used for communications between critical time sensitive and video related ECUs. Only two ECUs are ever connected to a Automotive Ethernet network. The Automotive Ethernet network use a twisted pair of insulated copper wires for the data bus. One wire is designated as Ethernet (+), the other is Ethernet (-). Connectors house the network circuit terminals in adjacent cavities and connect them to a module. The connectors also connect certain branches of wiring in-line along the wiring harness. A gateway module is used to link A.E. to other communication networks. A.E. messaging from multiple ECUs can be mirrored/reflected using an ethernet switch, that are internal to the Security GateWay (SGW) Module and Radio at the Diagnostic Port/Data Link Connector (DLC). The internal ethernet switch joins multiple physical connections and can independently forward messages from one A.E. network to another A.E. network.
