RS231/485/422 Serial Fiber modem
Overview
FM280 is a RS-232/RS-485/RS-422 serial fiber modem, designed for industrial standard。The hanging designs supporting DIN-rail installation. Now, many user choose RS-232/RS-485/RS/422 serial fiber modem to solve electromagnetic interfere and extend RS-232/RS-485/RS-422 serial transmission distance to several kilometer even several ten kilometers. FM280 can providers-232/RS485/RS-422 serial port to port transparent transmission. Due to adopt fiber transmission, it transmit the fiber signal in the fiber. There is no electric conduct. So it have good ability conflicting interfere, high voltage and thunder.
