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

This device adopts an industrial-grade design with large-scale FPGA technology, providing 2 serial ports that support RS232/422/485 interfaces simultaneously on each port. It is the best choice for connecting remote terminal units (RTUs) to hosts or distributed data acquisition systems (SCADA) controllers, with a high performance-to-price ratio. The effective communication distance can reach up to 0-120 kilometers, and the communication speed of the serial port can reach up to 0-256KBPS.

● The device provides 2 serial ports, with each port simultaneously providing RS232/422/485 serial interfaces (interface type can be set via DIP switches), making it easy to activate on-site services.

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

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

● The serial channel can transmit asynchronous serial port data with adaptive baud rates ranging from 0-256Kbps.

● The serial port interface is protected against lightning strikes according to the IEC61000-4-5 (10/700μS) standard: differential mode (6KV impedance at 2Ω); common mode (6KV impedance at 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 supply inputs, and reverse polarity 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.
