● 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.
