Block Diagram
Work mode
Server
The server listens to the specified port and waits for the client to connect,
The data sent by the serial device will be transparently transmitted to all
successfully connected clients through the serial device server.
Client
The serial device server initiates a 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
N540 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 N540 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 the production process control more refined.
