RS232/RS485/RS422 to fiber optic converter/serial to fiber modem(MODEL271)

extend serial transmission distance up to 2-5 km (multi-mode fiber) or up to 20-120 km (single- mode fiber).

Introduction:

The Model271 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. Model271 converters are used to extend serial transmission distance up to 2-5 km (multi-mode fiber) or up to 20-120 km (single- mode fiber). Note that the RS-232 and RS-422/485 interfaces cannot be used on the same Model271 at the same time to convert to fiber. Auto Baud Rate Detection.

  

Features:

1.          Auto sense serial signal rate, zero delay automatic transmit

2.          500Kbps the highest baud rate

3.          Supply three interface (RS232/485/422)

4.          Multi-mode 2KM, signal-mode 20~120KM

5.          Compact Size

6.          Decreases Signal interference

7.          DIN Rail or Wall-mounting
