Specifications

FM280 RS232/485/422 serial optic fiber modem


Overview

FM280 is a RS-232/RS-485/RS-422 serial fiber modem, designed according to industrial standard. The hanging designs support DIN-rail installation. Now many users choose RS-232/RS-485/RS-422 serial fiber modem to cope with electromagnetic interference and extend RS-232/RS-485/RS-422 serial transmission distance to 2km (multi-mode fiber) or up to 20/ 40/ 60km (single- mode fiber). FM280 can provide port-to-port transparent transmission among RS-232, RS-485 and RS-422 serial ports. It has anti-jamming function, surge protection function and lighting protection function, because it transmits the optical signal through fiber cable,

Features

  • Zero delay automatic transmission;
  • Adopt automatic monitoring serial signal rate, auto distinguish and control data transfer direction;
  • Supply three interfaces (RS232/485/422);
  • Operation wavelength: 850nm (multi mode), 1310nm (single mode);
  • Transmission distance: Multi-mode 2KM, signal-mode 120KM;
  • Power supply: 5~40V DC (outside power), or 85~265V AC (inside power);
  • Providing 600W surge protection and 15KV Electrostatic protection.
