    Note: This kit includes the AU power adapter, DB9 cable, and connectors.

    USR-N580 is an 8 Ports RS485 Serial Ethernet Converter and designed to realize bidirectional data transparent transmission between the serial port and the Ethernet port. The 8 RS485 ports can work independently and do not affect each other. Each port can be configured for different baud rates. It supports 600bps~921600bps wide baudrate.

    • 8 serial ports support RS485 communication, indicator lights (TX/RX)
    • Functions of Modbus gateway, Modbus RTU to Modbus TCP, Modbus polling
    • Support TCP Server, TCP Client, UDP Client, UDP Server, HTTPD Client working modes
    • Support virtual serial port and provide corresponding software USR-VCOM
    • Serial baud rate from 600bps to 921.6Kbps; Parity of None, Odd, Even
    • Functions of Modbus gateway, Modbus RTU to Modbus TCP, Modbus polling

    Free Choice of Multiple Working Modes

    N580 supports TCP Client、TCP Server、UDP Client、UDP Server、Httpd Client (later support MQTT Client) and other modes; only a simple configuration, you can achieve data pass-through function.

    Advanced Hardware Protection

    N580 supports Level 4 ESD (Static), level 3 Surge (Surge), level 3 EFT (Electrical Fast Transients), internal process watchdog, and external hardware watchdog, to ensure normal operation of the equipment and immunity from the outside environment interference.

    ESD Protection

    Prevent electrostatic damage to equipment, such as human electrostatic, dust electrostatic, electric power application of environmental arc, etc.

    Contact Level 4 (±8KV)
    Air Level 4 (±15KV)
    No Restarting

    EFT Protection

    Avoid instantaneous big electric current because of the circuit such as lightning
    stroke, power switch, etc.) when causing damage to equipment hardware.

    Pulse Group: Level 3 (2KV) No Restarting
    Surge Protection
    Anti Surge: Level 3 (2KV) No Restarting


    internal process watchdog and external hardware watchdog work 24 hours without stopping steadily

    More Features

    Application Case

    Network Monitoring of Industrial Automation

    Traditional network monitoring of industrial automation actually without networking. N580, integrating optimized TCP/IP protocol stack, provides network scheme of serial port data to TCP/IP, which can greatly improve the level of industrial automation.

    Unattended Weighing

    N580 is connected with the barrier gate to facilitate the control center to control
    the gate switch remotely through Ethernet. At the same time, many serial ports of
    N580 can connect peripherals like weighing instruments, LED displays, RFID
    readers, vehicle induction coils, ticket printers, fitting more application scenarios.

    Network Alarm for Electrical Fire

    N580 can communicate with the serial port of the electric fire alarm to transmit the
    alarm information to the server platform quickly, and remind the staff to pay attention
    to the fire information, and reduce the loss of people and property.
