2 Port Serial Device Server

2 Port Serial Device Server


USR-N520 is 2-port serial to Ethernet converter. It adopts Cortex-M7 solution,which has a main frequency up to 400MHz, powerful performance, fast transmission speed, and high reliability. Equipped with a deeply optimized TCP/IP stack, built in hardware and software watchdog and a variety of keepalive mechanisms,USR-N520 keeps online all the time. It supports TCP Client, TCP Server, UDP Client, UDP Server and HTTPD Client working modes, achieves data transparent transmission via simple configuration.

● Supports 2 serial ports working independently.
● Supports 5-36V wide voltage input, with reverse polarity protection.
● Supports connecting to Virtual COM Port Driver (USR-VCOM).
● Supports static IP and DHCP client.
● Supports Modbus RTU to Modbus TCP protocol conversion.
● Supports configuring parameters via built-in webpage.
● Supports upgrading firmware via built-in webpage and configuration software, more convenient.
● Supports hardware watchdog, automatically restarts when the device goes down.
● Supports serial and network AT commands.
● Supports UDP broadcast function.

Work mode of 2 serial ports serial to Ethernet servers USR-N520-h7:TCP Server

Work mode

TCP Server

The server listens to the specified port and waits for the TCP client to connect,
the data sent by the serial device will be transparently transmitted
to all successfully connected clients through the serial device server.

serial rs232 to ethernet converter/485 to ethernet/converter serial to ethernet USR-N520-h7:TCP Client

TCP Client

The serial device server initiates a TCP connection to the specified IP address.
If the connection fails, the serial server will continue to try to
reconnect until it succeeds. If the connection is successful, the server can
transparently transmit data with the serial device in two-way.

work mode of serial rs232 to ethernet converter/485 to ethernet/converter serial to ethernet  USR-N520-h7:UDP mode

UDP mode

The serial device server sends the data of the serial device to the designated IP network device.
The serial device server monitors the port meanwhile and forwards
all received data to the serial device.

work mode of rs232 to ethernet converter/modbus to ethernet converter/rs485 to ip converter/converter rs485 to ethernet USR-N520-h7: HTTPD Client

HTTPD Client

Serial port data can be submitted to a specified server by GET or POST method.

Application Case

Charging Pile Application Case

N520 can connect the charging pile to the charging intelligent service platform to
realize two-way data transmission between the charging device and the platform.
The billing information and power usage can be viewed remotely through
the platform to facilitate operation and maintenance.

Application Case of modbus rs485 to ethernet converter USR-N520-h7

Industrial Automation Application Case

The application of N520 in traditional industrial scenarios can effectively solve
the problem that workers need to monitor equipment on-site, save labor costs,
and increase production efficiency and safety factors. Data management makes
he production process control more refined.
