RS232/485 Over Fiber Card

FRM220-Serial & FRM220-Serial-SFP

The RS232/485 over Fiber Card (FRM220-Serial) provides a fiber modem solution to extend asynchronous RS-232, RS-422 or RS-485 transmission distance up to 2km over multimode fiber or up to 120km over single mode fiber. The converter is equipped with multiple interface circuits for connection to RS-232 or RS485/422 (2 or 4 wire, full or half duplex).

The FRM220-Serial secures data transmission over EMI resistant fiber at speeds up to 256kbps for RS-232 or up to 1024kbps for RS485/422. When the FRM220-Serial/485 card is placed in the FRM220 rack with NMC management, in-band management allows configuring and viewing the card and remote converter's status, type, version, fiber link status, data link status and alarms. When placed in a single slot chassis and used standalone without management, the card may be configured by DIP switches.

Features
  • Extend asynchronous serial transmission up to 120km over fiber
  • In-band network management via terminal, Web or SNMP in FRM220-CH20 chassis with NMC
  • Selectable data interface for RS-232/ 485
  • RS232/Async. 3W or 5W up to 256Kbps
  • RS485/Async. 2W (half duplex) or 4W (full duplex) up to 1Mbps
  • Standalone RS232 console management via CH01M
  • Software selectable two wires (half duplex) or four wires (full duplex) RS-485
