RS422 Optical Fiber Modem

Product function: The fiber modem is RS422 to fiber converter which realizes transmission of the RS422 signal on fiber. This product has solved the problem of contradiction between communication distance and communication rate of RS422 port. At the same time, it also has solved the problem of electromagnetic interference, earth link disturbance and thunder/lightning destruction, thus greatly enhancing reliability, security and privacy of data communication. It can be widely used in various kinds of situations such as industrial control, process control and transportation control, and especially suited in bank, electric power as well as departments and systems which have special request to the electromagnetic interference environment. Features:       ●   Based on self copyright IC.    ●   Serial date creates receive and send signal automatically.    ●   RS232/RS485/RS422 interface can be optional by dip switch.    ●   Serial port supports 0-115.2KBps baud rate auto-negotiation.    ●   C
