Allows two computers to be connected directly via the LAN port. Good for file transfers or two-player game servers without the need for a network switch. Only one adapter is required to create a Crossover cable from a regular CAT5e/6 cable; it does not matter which end the adapter goes on.
Convert any regular CAT cable into a Crossover cable with one simple adapter!
Generally, computer networks require a router or switch to manage all the connected devices. But if you just need to directly connect two computers together, you can skip the hub and connect them directly if you have a Crossover cable. Twenty years ago, Crossover cables were pretty common in a variety of lengths, but now it's far easier to just attach an adapter like this to any regular CAT5 or CAT6 cable you already have on hand.
Use Cases
I think the best use of a Crossover adapter is for backing up or recovering files from one computer to another, in situations where you don't already have a network switch available, or you don't want your old PC to see the internet. Sure, you could use a USB stick or portable HDD, but that means copying stuff twice at slower speeds.
However, a Crossover cable is just the start. Linking two computers doesn't automatically give you full access to all your files, so there are some extra steps involved in sharing, accessing and copying the data you want to save. Both computers need to be operational for this to work. If you have a dead PC and want to recover files, try a USB to HDD adapter instead.
