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.

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.

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.

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.

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.
