Related Categories:Modems
RS485 to optic fiber converter, easy to installation, plug and play, SC,FC, ST connector options.
The Model277/B Series converter is equipped with a multiple interface circuit that can handle RS-422/485 serial interfaces andmulti-mode or single- mode fiber. Model277/B converters are used to extend serial transmission distance up to 2 km (multi-mode fiber) or up to 20, 40, 60km (single- mode fiber). Note that the RS-422/485 interfaces cannot be used on the same Model277/B at the same time to convert to fiber.Auto Baud Rate DetectionThe Model277/B 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-422/485 to fiber converter without any problem. Features1.Auto sense serial signal rate, zero delay automatic transmit2.Adopt automatic send data control, auto distinguish and control data transfer direction3.0-120Kbps the highest rate 4.Supply two interface (RS485/422)5.Multi-mode 2KM, signal-mode 20KM, 40KM, 60KMCommunication | Standard | Accord RS-485, RS-422 standard |
