![]() ![]() I know that you see this all over the place, but it is WRONG. ![]() There's two ways to wire a connector : T568A (the one that starts with green, on the right) and T568B (the one that starts with orange) :įor a regular cable, you use same version on both ends (either T568A - T568A or T568B-T568B), for crossover cable one end must have T568A and the other end must have T568B (like in the picture above). It simply reverses some of the pins so that the output on one computer is being sent to the input of another. Some of us have fond memories of using a cross-over cable to play multiplayer games before the internet was a thing.Gigabit network cards have auto-detection of pair order, so you can use a plain network cable (like the one you use between computer and router) and make the connection between two gigabit network cards.Ĭrossover cable is only required if one of the cards is not capable of 1 gbps or if for some reason (buggy drivers, buggy chip) it can't automatically detect the pair order. However, a crossover cable can be used to connect two devices directly, without the need for a router in the middle. The router takes all the bits being sent out by the computers and relays them onto the other devices on the network, or out to the wider internet. In a Ethernet networking environment - like in a family home with multiple PCs that are wired - the computers must all connect to a central router. If you're interested in learning more about networking in general, we have a complete Beginner's Guide to Home Networks you should take a look at first. ![]() However, we've never described how to make a cross-over cable. The article may be old, but it's still as relevant today as ever. ![]() We've showed you before how to make your own straight-through Ethernet cabling. ![]()
