Model : Model271
The Model271 Series serial to fiber optic converter is equipped with a multiple interface circuit that can handle RS-232, or RS-422/485 serial interfaces and multi-mode or single- mode fiber. Model271 converters are used to extend serial transmission distance up to 2-5 km (multi-mode fiber) or up to 20-120 km (single- mode fiber). Note that the RS-232 and RS-422/485 interfaces cannot be used on the same Model271 at the same time.
Features
1.Auto sense serial signal rate, zero delay automatic transmit
