MODEL271-M: Bộ chuyển đổi RS-232/RS-485/RS-422 sang quang Multi-Mode 3Onedata 

The Model271 Series serial to fiber optic 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.

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
