1. Introduction
1.1. Overview
USR-M300 is a high-performance and scalable edge IOT gateway. This device integrates edge collection,
data calculation, data reading and writing, active reporting, linkage control, IO collection and control and other
functions. The collection protocol includes standard Modbus protocol and a variety of common PLC protocols, as
well as industry-specific protocols. At the same time, the product also has routing and VPN as well as graphical
programming functions to ensure data transmission security. Using graphical programming, users can develop
independently to achieve the required functions.
USR-M300 is embedded in Linux kernel, with a main frequency of up to 1.2Ghz. It can access the Internet via
Ethernet port, ADSL and LTE cat4 cellular network to achieve easy network deployment.
It is widely used in various industrial intelligent solutions such as industrial robot, smart factories, smart
agriculture, smart water management system etc.
1.2. Features
•Dual-core professor with ultra-high performance, the main frequency is up to 1.2Ghz, providing high-
performance processing resources for edge computing.
•Supports Python development, for developing user custom applications.
•Supports graphical programming to facilitate user development.
•LTE 4G and Ethernet network serve as backups for each other to ensure stable network transmission
without downtime.
•Integrated 1*WAN/LAN and 1*LAN Ethernet port, VPN and firewall protection to ensure safe data
transmission.
•Integrated 2 serial ports: 1*RS232/485, 1*RS485, which can transform traditional serial devices into IOT
devices.
•Comes with IO interface: 2*DI, 2*DO, 2*AI, flexible expandable IO module is supported.
•Powerful edge gateway function: supports edge collection, edge computing, group reporting, and
supports real-time collection of up to 2000 points.
•Supports major industrial protocols including Modbus TCP/RTU, PLC protocols and OPC UA Server.
•Support 2 socket channels, each channel supports TCP(SS)/UDP, MQTT(S) protocols.
•Cloud support: MQTT via AWS IOT, Alibaba Cloud, and PUSR Cloud.

Open the browser, enter 192.168.1.1 in the URL blank, and press Enter, it will navigate to the following webpage.
After entering the login password, clicking login, the web page will show configuration page of USR-M300.
Figure 1. Login webpage
2.3. Brief introduction of the webpage
There are several tabs on the top of the webpage, users can set parameters of USR-M300 on the tab pages.
➢Overview：On this page, users can quickly learn about the running status of the gateway, like system
information, device status, cellular information and etc.
➢Network: In this interface, there are many categories related to network connection. Users can set
parameters such as WAN port, LAN port and cellular network.
➢Edge Computing: With this functionality, the M300 gateway serves as host and actively sends the
polling acquisition command to periodically obtain the point data of the serial and Ethernet devices

4.2. Cellular
On this page, users can check the cellular information like the signal strength, IP address and so on. The APN
information can be set in this page also.
4.3. Ethernet Port
On this page, users can change the work mode of Ethernet Port1. This port is WAN mode by default. And it
can be changed to LAN mode. Then the users can get 2 Ethernet ports.

4.4. WAN Interface
User can set the parameters of WAN port like network mode, DNS mode and MTU.
4.5. LAN Interface
Users can set the basic information of LAN port like IP address, netmask and DHCP service. When the M300
enables the DHCP service, it can assign IP address to the terminal device connected to M300 via LAN port.

4.6. Routing
On this page, users can check the routing table and add needed static routing to USR-M300.
5. Edge Computing
5.1. Edge Mode
The edge mode is edge gateway by default. User can change the mode to Graphical Programming mode.
The Graphical Programming is based on Node RED, in this mode, user can develop the application about the
edge computing that they need.
