Enabling Edge-Device
Connectivity in the IIoT Era.

Widely supports connecting the IoT platform with stardard MQTT protocol

Edge Computing

N540 actively execute data collection and internal calculate,then transmits
to cloud platform by customized Json format. Edge computing gateways
can effectively relieve the pressure on the server.

Data transmission encryption

Supports SSL/TLS encryption in TCP client, HTTP client and MQTT operation modes
Supports two-way certificates authentication

PUSR Cloud Management

Easy to achieve edge computing, pair connection, remote operation and maintenance.

Modbus Gateway

Transfer between Modbus RTU and Modbus TCP protocol,
support Modbus multi-host polling. Support up to 128 data points
for data collection and Modbus address mapping.

Comparison of new and old schemes

Scheme upgrade to provide better experience

Master chip adopts ST crotex-M7 core, the main frequency is up to 400Mhz,
fast processing speed, high stable and reliable performance.

Multiple hardware protection

Redundant Power Supply

Wide input voltage DC 5-36V,
with reverse polarity protection.

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.

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.
