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.
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.

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.
