Description
Fiber Modem 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. they 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 Model168 at the same time to convert to fiber. Auto Baud Rate Detection The Model168 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 a devices baud rate is changed, the signal will still be transmitted through the RS-232 or RS-422/485 to fiber converter without any problem.
