RJ45 Wiring for CAT5/5e/6
Cabling transmits information, and to get that information to where it needs to go the correct connections must be make to an RJ45 connector. The cable run needs to terminate into a connector, and that connector needs a jack to plug into. The Registered Jack 45 (RJ45) is a standard type of physical connector for networking cables used widely in networking. Modern Ethernet cables feature a small plastic plug on each end of the cable. That plug is inserted into the RJ45 jacks of Ethernet devices.
RJ45 plugs feature eight (8) pins to which the copper cores of a cable interface electrically. Each plug has eight locations (positions), spaced about 1mm apart. Individual wires are inserted using special cable crimping tools.
Wiring for a RJ45 plug is shown below.
Wiring for RJ45 Jack Sockets
The RJ45 port is the network port on a computer. This socket has many names. It is also known as the Ethernet port, the network adapter, the network jack or the RJ45 jack. A “port” is another name for a socket on a computer, as is “jack.” The RJ45 port is wired directly onto the network adapter inside the computer, and so is the cable interface to that device. In this instance you will be wiring an RJ45 Wall Socket. To wire your cable into the socket use an IDC insertion tool to insert each wire core into it’s corresponding terminal.
