Product Name:8*RS485 Ports Serial Ethernet Converter

  • Model:USR-N580

Basic Function

Bi-directional data transmission between RS485 port and Ethernet

Wide Baudrate

The 8 RS485 ports can work independently and does not affect
each other. Each ports can be configured for different baud rates.
It supports 600bps~921600bps wide baudrate.

Cascade Connection Function

Dual Ethernet port 10/100mbps It supports switch function. Other devices can be cascaded through USR-N580

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 ).

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.

Advanced Hardware Protection

N580 supports Level 4 ESD (Static), level 3 Surge (Surge), level 3 EFT (Electrical Fast Transients),
internal process watchdog and external hardware watchdog, to ensure normal operation of the
equipment and immunity from the outside environment interference.

ESD Protection

Prevent electrostatic damage to equipment,
such as human electrostatic, dust
electrostatic, electric power application of
environmental arc, etc.

Contact Level 4 (±8KV)
Air Level 4 (±15KV)
No Restarting

EFT Protection

Avoid instantaneous big electric current
because of the circuit such as lightning
stroke, power switch, etc.) when cause
damage to equipment hardware.

Pulse Group: Level 3 (2KV) No Restarting
Surge Protection
Anti Surge: Level 3 (2KV) No Restarting


nternal process watchdog and
external hardware watchdog work
24 hours without stopping steadily

More Features

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.
