Sell RS232 / RS485 / RS422 Serial Fiber Modem

Specifications

The Model277 convert is equipped with a multiple interface circuit that can handle RS-232 or RS-422/485 serial interfaces into multi-mode or single-mode fiber. Model277converters are used to extend serial transmission distance up to 2km (multi-mode fiber) or up to 20km (single-mode fiber). Note that the RS-232 and RS-422/485 interfaces cannot be used on the same Model277 at the same time to convert to fiber. The Model277 series incorporate a method for automatically detecting the serial signal baud rate by hardware. This is an extremely convenient feature for the user. Even if a device's baud rate is changed, the signal will still be transmittedthrough the RS-232 or RS-422/485 to fiber converter without any problem.
