Serial RJ45 Adapters

A Registered jack (RJ) is a standardized physical Network Interface — both jack construction and wiring pattern — for connecting telecommunications, or data equipment (commonly, a telephone jack) or computer networking equipment to a service provided by a local exchange carrier, a long distance carrier, or a data network in the case of the RJ45 connector. The standard designs for these connectors and their wiring are named RJ11, RJ14, RJ45, etc. These interface standards are most commonly used in North America, though some interfaces are used world-wide[

RJ45 is a standard type of connector for network cables. RJ45 connectors are most commonly seen with Ethernet cables and networks. Several other kinds of connectors closely resemble RJ45 and can be easily confused for each other. The RJ-11 connectors used with telephone cables, for example, are only slightly smaller (narrower) than RJ-45 connectors.
