Product Name:8*RS485 Ports Serial Ethernet Converter

  • Model:USR-N580

Enabling Edge-Device
Connectivity in the IIoT Era

Widely supports connecting the IoT platform with stardard MQTT protocol

Edge Computing

N580 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.

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 stable.
(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.
