USR IoT Industrial PCs: Experts Answer Engineers' Questions

In a recent MasterClass hosted by SOS electronic, industry experts Dean Gao and Stephen Dou from USR IoT shared their perspective on modern industrial computing solutions. The session focused on the specific technical questions raised by an engineering audience, diving into everything from embedded Linux customisation to navigating European compliance standards like RED certification.

We have distilled the standout technical moments and the questions that resonated during the session into the following brief. 

Q&A About USR IoT Industrial PCs

Linux and Software Access for Industrial PCs

• Where can I download the Linux images for the USR IoT industrial computers?

To ensure hardware compatibility and system reliability, USR IoT manages these images directly rather than hosting them for public download.

Once you have selected a device, the R&D and SOS electronic support teams work with you to provide an image tailored to your specific hardware version and project needs. This hands-on approach ensures system reliability, long-term support, and rock-solid compatibility from day one.

If you are currently in the project evaluation phase, the best move is to share your application details with us so we can ensure you have the right image from the start.

• Is the source code for the OS and proprietary applications available?

The USR IoT devices run a streamlined embedded Linux system, and when it comes to the code, the experts explained their balanced approach:

Source code availability:

• SDKs: These are fully available and comply with standard requirements to get your own development moving. 
• Proprietary software: To keep the system's core integrity and security intact, the source code for in-house drivers and applications isn't part of the public distribution.

Source code access is handled through the PUSR technical support process on a project-by-project basis. If you’re planning a deep customisation or unique secondary development, our engineering teams at SOS electronic, alongside PUSR’s R&D, can work directly with you to evaluate the specifics. We’re here to ensure you have the technical documentation and development support needed to get your solution up and running.

Development & Testing of Industrial PCs

• Do you have an application for testing digital input/outputs and analog inputs/outputs of industrial computers?

The USR IoT team confirmed that verifying I/O is a built-in feature of their ecosystem.

USR IoT (PUSR) computers provide engineers with several ways to verify signal status:

• Built-in Wukong Edge within the webpage for basic I/O status monitoring
• Configuration and debugging tools that allow users to verify signal input/output status
• Relevant SDK for customers who prefer to develop customized testing applications 

Beyond the tools, the USR IoT team can also provide direct guidance and documentation for standardising your I/O testing procedures based on your specific project requirements.

Edge Computing & Data Security of IPCs

• Does Wukong Edge automatically send data to the USR IoT cloud?

The answer from the experts was a definitive "no." Wukong Edge is designed as a local-first edge computing platform. All processing, storage, and protocol conversions happen on the device itself. Data is only transmitted externally if you explicitly configure your own private server, cloud platform, or third-party IoT service.

In practice, this means:

• Full data ownership 
• Flexible network deployment
• Compliance with industrial cybersecurity requirements
• Suitability for projects requiring local data processing

If your infrastructure demands it, we also support private cloud deployment and full on-premises server integration to keep your data exactly where you need it.

Compliance & Standards

• How do PUSR devices comply with the Radio Equipment Directive (RED) and the Cyber Resilience Act (CRA)?

The USR IoT team highlighted that the majority of their devices and controllers have already obtained RED certification (EN18031), with the rest of the portfolio following close behind. 

Regarding the Cyber Resilience Act (CRA), while it doesn't become mandatory until 2027, product and processes adjustments to fully comply with CRA standards are already under way. 

This approach ensures that all PUSR devices deployed in Europe will meet both current regulatory requirements and upcoming cybersecurity standards, giving PUSR customers confidence in safety, compliance, and long-term reliability.

Documentation & Support

• With Teltonika as a European competitor, customers are used to exhaustive documentation. How is USR IoT bridging the gap to match that level of technical depth?

Teltonika is an experienced European manufacturer, and its documentation system is well-established after many years of local market development.

USR IoT recognises that comprehensive documentation is critical for system integrators and technical users; it’s the foundation of a smooth project. 

PUSR has launched a major ongoing initiative to overhaul its technical library. They are currently focusing on enhancing:

• Product user manuals
• Configuration guides
• Application notes
• Firmware instructions
• Integration documentation for industrial protocols 

In the meantime, SOS electronic and PUSR engineering teams provide direct technical support to assist you with deployment and integration.

Government Solar Project

• What is the most complex government-level project you have handled?

One of PUSR's most significant projects involved remote monitoring and control of over 1 000 solar plants.

In this project, PUSR computers and edge gateways were deployed to:

• Collect real-time data from field devices, including inverters and smart meters
• Ensure secure communication via VPN, OpenVPN, and SSH
• Enable flexible configuration and remote management
• Support integration with the government’s central monitoring system

The project was particularly challenging due to the sheer scale and the need for reliable connectivity in remote locations. It required a deep collaboration between R&D and technical support teams to deliver a robust, secure solution that continues to operate reliably today.

Competitive Advantages of USR IoT IPCs

• What is the primary advantage of USR IoT IPCs over legacy brands?

When comparing themselves to established brands that have been in the market for over 20 years, the experts pointed to their ability to move faster than the competition: 

• Fast product iteration - Adapting to new industrial protocols, interfaces, and customer requirements significantly quicker than more rigid manufacturers.
• Flexible customisation - Firmware, hardware configurations, and application integration can be tailored for each project in a way that legacy brands struggle to match.
• Comprehensive connectivity - Industrial routers, serial-to-Ethernet/Wi-Fi converters, edge gateways, CAN devices, and more, all in a unified portfolio.
• Responsive project-specific support - Direct collaboration between PUSR R&D and SOS electronic ensures technical hurdles are resolved with the speed and depth your project requires.
• Competitive cost-effectiveness - High-quality industrial solutions at a favorable price point, especially for large-scale IoT and automation projects.

This combination of agility and engineering depth makes USR IoT particularly suitable for system integrators, energy projects, OEMs, and infrastructure deployments that require both high reliability and the flexibility to adapt to evolving requirements.

• How does USR IoT navigate the competitive landscape in Europe, and what are the primary differentiators compared to established brands?

In the European market, there are several well-established industrial communication brands. Rather than chasing a single competitor, the experts explained that they position USR IoT as a flexible, cost-effective provider of industrial IoT connectivity.

Compared to traditional European brands, the main advantages are:

• Better cost-performance ratio for large-scale deployments
• Flexible customisation capability for project-based requirements
• Faster product iteration driven by strong in-house R&D
• Comprehensive product portfolio covering serial connectivity, industrial routers, IoT gateways, and edge computing devices
• Responsive technical support for overseas partners
