The OMl277 series 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. OMl277 converters are used to extend serial transmission distance up to 2 km (multi-mode fiber) or up to 20 km (single- mode fiber). Note that the RS-232 and RS-422/485 interfaces cannot be used on the same OMl277 at the same time to convert to fiber.
The OMl277 series incorporates a method for automatically detecting the serial signal baud rate by hardware. This is an extremely convenient feature for the user. Even if adevice's baud rate is changed, the signal will still be transmitted through the RS-232 or RS-422/485 to fiber converter without any problem.
