2 Port Serial to Fiber Converter | RS485/422/232 Support All at Once

View : 230
Type : Serial to Fiber Converter
Description :

The serial to fiber converter adopts industrial-grade and large-scale FPGA design, it provides 2 serial ports, and each port supports RS232/422/485 three interfaces at the same time.

Overview

This product adopts industrial-grade and large-scale FPGA design, it provides 2 serial ports, and each port supports RS232/422/485 three interfaces at the same time. This device is the best choice for connecting the remote terminal unit (RTU) to the host computer (HOST) or distributed data acquisition system (SCADA) controller, with a high performance-price ratio. The effective communication distance can reach 0-120 KM, and the communication rate of the serial port can reach 0-256KBPS.

 

Due to the use of optical fiber as the transmission medium, it can completely avoid the threat of lightning, surge, electromagnetic interference, and other threats to communication equipment in harsh environments, and at the same time save the investment in lightning and surge protection equipment when using copper wires.

Features

Integrated circuits based on independent intellectual property rights;

Provide 2 serial ports, and each serial port provides three serial interfaces of RS232/422/485 at the same time (the interface type can be set by DIP switch), which is convenient for on-site service opening;

It can automatically detect and control the RS-485 data flow. It is unnecessary to use the handshake signal to control the data flow;

It has the ability to automatically detect the baud rate of the serial port signal;

The serial number channel can transmit asynchronous serial port data adaptive from 0-256Kbps baud rate;

Serial port interface anti-radar to IEC61000-4-5 (10/700μS) differential mode: 6KV impedance (2Ω); common mode: 6KV, impedance (2Ω) standard;

When dual DC power supply (5.08 terminal):

  It can be powered by DC9-55V or AC7-50V wide-range power supply. The power supply has the function of polarity automatic detection, and there is no need to distinguish between positive and negative poles during installation;

  ● Support internal isolation, redundant dual power input; anti-reverse protection;

When AC power supply (three-position plum blossom AC seat):

  Support AC~85-265V AC, or DC110-300V DC wide range input;

● Provide DIN 35mm rail or wall-mounted installation.
