1. Introduction
1.1 Overview
USR-N580-H7 module is designed to realize bidirectional data transparent transmission between the serial
port and the Ethernet port. User does not need to care about the specific details, the module completes the
protocol conversion internally. The serial port side is the RS485 level data, and the Ethernet port side is the
network data packet. The USR-N580 device server is rugged, user-friendly, making simple and reliable serial
to Ethernet solutions possible. There are two ways to access the configuration settings: web page, Windows
utility.

2.2.2 Indicators
Indicator
Description
Power
Indicates power. It is on when power is supplied
Work
Indicates working status. It twinkles when N580 works well. If it is on or off
for a period, N580 works improperly, you should disconnect the power and
restart.
TX n
It twinkles when port n sends data.
RX n
It twinkles when port n receive data.
Status
Error indicator.
Link
Always on when establish a socket connection.
2.3 Connecting Hardware
2.3.1 Serial Connecting
Connect a serial data cable between the N580 and the serial device. And the pin wiring should be: A to A, B to
B, GND to GND. Please set the serial parameters of N580 to be consistent with RS485 serial device. Serial
parameters of N580 default to 115200, NONE, 8, 1.
2.3.2 Network Connecting
Connect one of the Ethernet cable to the N580’s 10/100M Ethernet port and the other end of the cable to the
Ethernet network. The green indicator light will always be on and the orange light will be twinkling.
USR-N580 User Manual technical support:h.usriot.com
Jinan USR IOT Technology Limited 10 www.usriot.com
USR-N580 has two Ethernet ports that can be used to cascade other devices like a switch.
2.3.3 Power Supply
Connect the power adaptor with the N580’s power input. If the power is properly supplied, the “Power” LED
will show a solid red color and the “Work” LED will show a twinkling green color.
3. Utility Configuration
3.1 Download the Utility
Be sure you have administrative privileges and disable any firewall/anti-virus software when installing
software.
Configuration utility download address:
3.2 Starting the Configuration Utility
3.2.1 Discovering Your Device Server
USR-N580 defaults to a static IP address 192.168.0.7, you can set the computer to a static IP address that in
the same network segment with N580, like 192.168.1.201. Then directly connect the Ethernet port of N580 to
the computer via a Ethernet cable.
USR-N580 User Manual technical support:h.usriot.com

1. Double-click the device name field, enter the default username (admin) and password (admin) to log in
to the device's web page.
2. Or you can right click the device name to directly log in to its webpage.

3.2.2 Network Settings
The device server must be assigned a unique IP address that is valid for your network. Both fixed and dynamic
IP addresses are supported.
Static IP address
To assign a fixed IP address, the IP Type must be set to Static IP. You also need to modify the Static IP address,
Submask,Gateway and DNS parameters. Make sure that the IP address is different from other network
devices in the LAN.
DHCP
Instead of assigning N580 device’s IP address, you will need to configure the device to get its IP address from
the appropriate server. Set the IP Type to DHCP, then the IP address and other parameters will be assigned
automatically. In this mode, cannot directly connect the device to the computer.
If the device has been configured correctly, you should be able to ping its IP address form the PC.

AT Command Set.
3.2.6 Update Firmware
Firmware updates can be made via webpage or configuration utility. Users can consult with sales or technical
support about the firmware. It is best to connect the device directly to the computer when upgrading.
1. After searching the device, right click the device name and select the Upgrade to start upgrading the
firmware.
