Product details

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

More Features

Synchronized baud rate

Change the baud rate, data bit, check bit and stop bit dynamically via network protocol

Registration package mechanism

When N510 is used as a TCP Client, it will automatically send a predetermined registration
package for identification after the link is established.The registration package data
can be IMEI code, ICCID code and custom registration data.

Serial / Network heartbeat packet

Network heartbeat packet: The serial device server sends a heartbeat packet regularly to notify
the server that it is active and maintains a normal network connection with the server.
Serial heartbeat packet: The serial device server notifies the serial device
it is active via packet, and this packet can also be used to actively capture sensor data.

Application Cases

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

he 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.
