YT-312 series of RS-232 line driver or line transceiver or long distance optical isolation repeaters, it can at the same time the communication distance of two asynchronous communication RS-232 device is extended to a maximum of 1.2 km. Due to the adoption of a balanced twisted pair transmission lines, greatly increases the communication distance. YT-312 small volume, no special requirements on the wire, no external power supply, can be directly inserted into the RS-232 interface equipment, very convenient to use. 312 series of products have been widely used in point-to-point RS-232 communication, multi user terminal and the host of the connection, RS-232 remote control system, program-controlled switchboard charging terminal, satellite receiver.
