Data transmission encryption

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

Edge computing

N510 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.

Modbus gateway

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

Comparision 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

High Reliability and Stability

Redundant Power Supply

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

Block Diagram
