RS-C250

RS-232/422/485 to Fiber Converter

The RS-C250 RS-C250 is a Multi-serial to fiber media converter, which adopts RS-232/RS-422/RS-485 triple mode circuits with auto baud rate and direction control. It extends the serial signal link distance to 2KM ( Multi-mode Optical Fiber) or 20KM (Single-mode Optical Fiber) and also provides good immunity of EMI/EMS. Further more, RS-C250 supports Chassis and DIN rail mount for quick and easy installation.
