Enabling Edge-Device Connectivity in the HoT Era
Widely supports connecting the IoT platform with standard MQTT protocol
Edge Computing

N580 actively executes data collection and internal calculatations, then transmits to cloud platform via customized JSON format.
Edge computing gateways can effectively relieve the pressure on the server.
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.
Basic Function
Bi-directional data transmission between RS485 port and Ethernet.
Block Diagram
Cascade Connection Function
Dual Ethernet port 10/100mbps It supports switch function
Other devices can be cascaded through USR-N580.
Free Choice of Multiple Working Modes
N580 supports TCP Client、TCP Server、UDP Client、UDP Server、Httpd Client (later support
MQTT Client) and other modes ; only a simple configuration, you can achieve data pass-through function.
Arm scheme (Cortex-M7 core)to provide a better experience
Arm Cortex-M7 Scheme,480Mhz CPU, 1M RAM +4M Flash
The scheme features short transmission delay, fast data transmission speed, flexible expansion, and stability.
(MQTT/SSL/IPV6 and other major protocols will come soon, please enquire directly for more information ).

Application Case
Network Monitoring of Industrial Automation
Traditional network monitoring of industrial automation actually without networking. N580, integrating optimized TCP/IP protocol stack, provides
network scheme of serial port data to TCP/IP, which can greatly improve the level of industrial automation.
Unattended Weighing
N580 is connected with the barrier gate to facilitate the control center to control the gate switch remotely through Ethernet. At the same time, many serial ports of N580 can connect peripherals like weighing instruments, LED displays, RFID readers, vehicle induction coils, ticket printers, fitting more application scenarios.
Network Alarm for Electrical Fire
N580 can communicate with the serial port of the electric fire alarm to transmit the alarm information to the server platform quickly, and remind the staff to pay attention to the fire information, and reduce the loss of people and property.
