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

The serial to fiber converter adopts industrial-grade and large-scale FPGA design, it provides 1 serial port, and the serial port supports RS232/422/485 three interfaces at the same time. This serial to fiber converter 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 0-120KM, and the communication rate of the serial port can go 0-500KBPS.

Due to the use of optical fiber as the transmission medium, threats to communication equipment such as lightning, surges, and electromagnetic interference in harsh environments can be avoided entirely. At the same time, the investment in lightning and surge protection equipment when using copper wires is saved.

● Integrated circuits based on independent intellectual property rights;

● The serial to fiber converter provides 1 serial port, and the 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 doing on-site service;

● It can automatically detect and control the RS485 data flow. It is unnecessary to use the handshake signal to control the data flow;

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

● The serial number channel can transmit asynchronous serial port data adaptive from 300-500Kbps 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 (Cross StyleAC seat):

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

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