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

This device features an industrial-grade design with large-scale FPGA architecture and provides one serial port, with each port simultaneously supporting RS232/422/485 three types of interfaces. The device is the best choice for connecting remote terminal units (RTUs) to hosts or distributed data acquisition systems (SCADA) controllers, with high cost-effectiveness. The effective communication distance can reach up to 0-120KM, and the communication rate of the serial port can reach up to 0-500KBPS.

● It provides one serial port, with each port simultaneously supporting RS232/422/485 three types of serial interfaces (interface types can be set via DIP switches), making it easy to enable business on-site.

● It can automatically detect and control RS-485 data flow without the need for handshake signals to control data flow direction.

● It has the ability to automatically detect the serial port signal baud rate.

● The serial channel can transmit asynchronous serial data with adaptive baud rates from 300-500Kbps.

● The serial port interface has lightning protection up to IEC61000-4-5 (10/700μS) standard: differential mode: 6KV impedance (2Ω); common mode: 6KV, impedance (2Ω).

● When dual DC power supply:

    ♦ 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;

    ♦ It supports internal isolation, redundant dual power inputs, and reverse connection protection.

● When AC power supply:

   ♦ It supports AC~85-265V AC, or DC110-300V DC wide-range input.

● DIN 35mm rail mount or wall-mounted.
