Products Content:
The GP-RS119 Series converter is equipped with a multiple interface circuit that can handle RS-232, or RS-422/485 serial interfaces andmulti-mode or single- mode fiber. GP-RS119 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 GP-RS119 at the same time to convert to fiber.Auto Baud Rate Detection
The GP-RS119 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.
