RJ-45 LAN Connector
The OVN provides a standard RJ-45 connector for
10/100BaseT Ethernet LAN connection. This section
describes the pin layout for the RJ-45 connector. Most
Ethernet local area networks use twisted pair wiring.
10/100BaseT networks are physically laid out in a star
topology, where each piece of equipment on the network is
connected to a central hub. The wiring is connected to
devices using a plug that resembles a phone jack called
RJ-45. See Table 1 for RJ-45 signals.
