Dynamic Crossing Over of Network Signals

Disclosed is a system that allows computers to use a regular CAT 5 ethernet cable as if it were a crossover cable. Networks are commonly realized today with the wiring of RJ45, 10baseT Cables. These seem to be very handy and readily available in today's work facilities. Many times, a user simply wants to make a direct connection between two computers using RJ45 cable. This is performed in the industry via a "Crossover" cable. Unfortunately, many times, a crossover cable is not available. However, a user may still want to connect two computers up directly. The following system aims to make this possible.

The idea is to facilitate direct RJ45 connections via a regular 10baseT cable between two computers using regular UTP (Unshielded Twisted Pair) cable. This will be made possible by "tricking" the ethernet card on both participating computers. In the control panel, the user will be able to pick the incoming signal on their ethernet card to be either a "Regular signal" or a "Crossed Signal." When a "Regular Signal" is picked, the ethernet card will act normally. However, when a "Crossed Signal" is picked, certain things will happen. Dynamically, the ethernet cards participating in the two computer network will read incoming signals on the regular RJ45 cable in a different way. Basically pins will be translated/mapped in a crossover fashion: Computer #1 (Signal T+) will read its pin #1 as Computer #2's pin #3 (Signal R+). Computer #1 (Signal T-)...
