► Ring and point-to-point transmission
► Extends RS-232/422/485 transmission up to 80 km
► Supports baudrates up to 115.2 kbps
► Industrial Wall Mount Compact size rugged case
The UF-277 RS232/422/485 serial fiber media converters are equipped with a multiple interface circuit that can handle RS-232 or RS-422/485 serial interfaces and multi-mode or single-mode fiber. UF-277 converters are used to extend serial transmission up to 2 km (UF-277-M with multi-mode fiber) or up to 40 km (UF-277-S with single-mode fiber). The UF-277 converters can be configured to convert either RS-232 signals, or RS-422/485 signals, but not both at the same time.
