Line Drivers Connection Diagram

Line Drivers - Connection diagram

A Line driver is an equipment which amplifies the signal flowing through a cable to it's original specifications. It is used in long distance communication. It has gots nosie filter and it supports RS-232 as well as RS-422 interface.
