Overview of 3onedata’s RS-232 Line Repeater Model 232D/9
Model 232D/9 is an industrial-grade pocket RS-232 line repeater with photoelectric isolation, which can convert RS-232 signal into current signal to extend the communication distance of serial port RS-232 to 2km.
Model 232D/9 obtains power from TXD, RTS and DTR signals of RS-232 port and need no external power supply. Serial ports are equipped with 600w surge protection and 15KV electrostatic protection, which could effectively prevent device from being damaged. Compering with other extending technologies, this one is one of the best solutions of extending RS-232 distance because of its long-distance transmission, stable performance, strong anti-interference ability and photoelectric isolation effect.
The design of Model 232D/9 complies with the requirements of industrial standard. It could be wildly used in application areas like electric power system, industrial automation control, RS-232 remote control system and SPC switch charging terminal, etc.
