Serial to Ethernet Converter USR-N520-H7 Introduction Serial to Ethernet Converters

Serial to Ethernet Converter USR-N520-H7 2-port serial to Ethernet servers can realize transparent transmission between TCP/UDP data package and RS232/RS485/RS422 interface.

• 2-port RS-232/422/485 serial to Ethernet servers.
• Power supply accepts wide voltage input range DC 5-36V.
• Support TCP server/client, UDP server/client, https client, Virtual COM.
• Support Modbus RTU to Modbus TCP.
• Support flow control CTS/RTS, XON/XOFF.
• Support 2 RS-232, RS-485/422 3IN1 serial port to 1 10/100Base-T(X) self-adaptive Ethernet interface.
• Configuration via Web Server page, AT commands, and Windows Utility.

Basic Function of USR-N520-H7

• Industrial Hardware Design.
  • Industrial solution TI cortex-M4.
  • Hardware Watchdog Design, never crash in 24 hours.
• Serial Port Switching Among RS232/RS485/RS422
• Power supply supports Anti-reverse.

Work Mode

• TCP Server
  • Serial to Ethernet servers USR-N520 listens on the setting port and waits for a TCP client connection.
  • The data which the serial ports sent out transparently.
  • Transmit to all connected TCP clients via USR-N520.
• TCP Client
  • Serial to Ethernet servers USR-N520 initiates a TCP connection to the set IP address.
  • If the connection fails, USR-N520 will keep trying to reconnect until it succeeds.
  • Once the connection is successful, the data will be transparently.
  • Transmitted between PC and serial device in bi-directional.
• UDP Mode
  • Serial to Ethernet servers USR-N520 will transmit serial data from serial device to target network device by UDP connection.
  • USR-N520 will listen to port and transmit all received data to serial device.
• HTTPD Client
  • Supports https Client mode which can transmit serial data to the https server in https format(GET/POST).
• WebSocket
  • Supports WebSocket Sever.
  • Built Websocket link with devices by Websocket of webpage HTML5.
  • Data transmission between built-in webpage and serial port in bi-directional.
  • Custom webpage and websocket are acceptable.
  • Achieves the functions of displaying data in real-time.

Features:

• Socket B function – Serial to Ethernet servers USR-N520 supports the secondary network link, which can send data to two servers. Used for data backup, remote diagnosis, and other requirements.

• Serial & Network Heartbeat Packet – Network Heartbeat Packet: Serial server maintains the normal connection with the server by sending heartbeat packet regularly. Serial Heartbeat Packet: Serial server informs serial device is active, can be applied in actively catching sensor data.

• Customize webpage, Synchronized baud rate, net printing, registration package, cloud.

Applications:

• Unattended Weighing Systems.
• Electric Power.
• Traffic Control.
• Industrial Automation.
