USR-N580 Introduction of Serial to Ethernet Converter Modules

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

Features of Serial to Ethernet Converter Modules USR-N580

  • 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 921.6K bps; Parity of None, Odd, Even.
  • Functions of Modbus gateway, Modbus RTU to Modbus TCP, Modbus polling.

More Features of Serial to Ethernet Converter Modules

  • Virtual Serial Port– It will Solve the problem of PC software as serial port that cannot communicate with network devices.
  • Serial Port / Network Heartbeat packet – Network heartbeat packet prompt the server and maintains a normal network link with it. Serial port Heartbeat Packet can Prompt serial-port device.
  • Modbus Gateway- Polling mechanism can effectively solve the problem of data concurrent or adhesion congestion.
  • Synchronous Baud Rate– Dynamically change the serial port server, baud rate, data bit, check bit, stop bit by network command.

Basic Functions of USR-N580

  • Bi-directional data transmission between RS485 port and Ethernet.
  • Cascade Connection Function – Dual Ethernet port 10/100mbps It supports switch function. Other devices can be cascaded through USR-N580.
  • Arm Cortex-M7 Scheme,480Mhz CPU, 1M RAM +4M Flash The scheme features short transmission delay, fast data transmission speed, flexible expansion, and stable.
  • 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 of ESD, EFT.
  • Watchdog: Internal process watchdog and external hardware watchdog work 24 hours without stopping steadily.

Application Field of Serial to Ethernet Converter Modules

  • Network Monitoring of Industrial Automation.
  • Unattended Weighing.
  • Network Alarm for Electrical Fire.
