Jack in

The action of Jacking-in is when a net operator sends his or her net navi into the cyber world. In MegaMan Battle Networks 1, 2, and 3, the PET contained a wire that plugged into the jack of an electrical unit. From Megaman Battle Network 4 on, all Navis jacked in by wireless transport. To jack-in with MegaMan in the games, Lan would have to be standing considerable close to the jack-in port.
