Direct Wired Connection (有線直結通信, yūsen chokketsu tsūshin; ; ; ), more simply known as direct connection (直結, chokketsu; ; ; ) or wired connection, is a very personal method of communication between Neuro Linkers, achieved by plugging in a cable directly into the Neuro Linkers. Unlike usual wireless connections, 90% of the security measures are invalidated during wired connections such as firewall that protect user from harmful files.
It is usually used by peoples who can trust each other, family members and lovers. They are also capable of sending each other softwares or are evenly checking back-up files from another person. For Burst Linkers, Direct Wired Connection can be used to transfer Enhanced Armaments or have Private Battles for Burst Points.
A commonly believed myth among teenagers is that the shortness of the cable that a pair uses indicate their emotional closeness.
The XSB cable is used for connection.
