Description

The AN-FM-RS232-M, AN-FM-RS422-M, AN-FM-RS485-M  family serial fiber modems-converters are standalone and rack mountable fiber 1 x RS232 / RS-422 / 485 modems available in a number of different models, with AC or DC power supplies built-in. The AN-FM-RS (M) family of modems may be applied in point-to-point applications or they may be installed and linked to a centrally located AN-CH07 chassis.

Fiber modem can be connected with RS232 ( or RS-485, RS-422) port of computer or other devices, small and flex. solve the problem of traditional RS232, RS-485 or RS-422 communication conflict between distance and rate. Electromagnetic interfere, lightning interfere ,improve the reliability ,safety,and security of data communication, suitable for industrial control, procedure control,and traffic control,especially for system in bank, electric, and environment which having special requirement for electromagnetic interfere.

Possible applications can be military control, industrial control,traffic control,video control, distribute data acquisition system,electric acquisition and control system, intelligent district , highway charging system.
