RJ45 is a standard type of connectors / plugs for network cables.
Such connector / plug terminates flat stranded cable, such as Cat5 8X8, in data applications. RJ45 has eight pins to which the eight wire strands of a cable are connected electrically inside of the RJ45 plug. Notation "Cat5 8X8" means that the ethernet cable is of the type "Category 5" with 8 wire strands at each end (8 narrow wires inside of the common enclosure ("jacket") of a network cable).
Without a plug it would be impossible to connect an ethernet cable into a computer port, and RJ45 seems to be one of the the most wide-spread type of plug.
If the connection between the ethernet cable, such as Cat5 8X8, and the computer becomes flaky, then it is necessary either to replace the whole cable, or to cut off the old RJ45 plug together with a short piece of ethernet cable, and to install a new RJ45 plug.
Below is a short algorithm how to attach a new RJ45 plug to the Cat5 8X8 cable.
* Cut the outer jacket of the whole ethernet Cat5 cable about 1.5" to 2" from the end. This will give you room to work with the wire pairs. Separate the pairs (8 wire strands are organized into 4 pairs) and align them in the definite order which is described in the next paragraph (and also depicted on the attached photo, click on the image to enlarge it). It is extremely important not to make a mistake and not to alter the the order of the eight wire strands. The order described below is officially known as 'EIA/TIA 568B wiring standard', and this particular wiring standard is used in the ethernet Cat5 cable that links 'WeatherLink' and processor 'c1pem1' (see 'Weather Station' wiki40 page). It might be that some other network cables our lab have different order of colors of wire strands, because there also exists another wiring standard 'EIA/TIA 568A'.
