June 15, 2026 – In a significant expansion of its industrial communication portfolio, HMS Networks has officially entered the Automotive Ethernet market. By launching its first-ever Automotive Ethernet product under the renowned PEAK brand, the company aims to bridge the gap between traditional vehicle networking and the high-speed requirements of the Software-Defined Vehicle (SDV). The new PAE-Media Converter represents a strategic pivot for HMS, signaling a commitment to providing comprehensive tools for automotive engineers navigating the complexities of 100BASE-T1 and 1000BASE-T1 networking.
The Core Innovation: Bridging the IVN Divide
As modern vehicles evolve into sophisticated data centers on wheels, the demand for high-bandwidth, low-latency communication has skyrocketed. Traditional CAN bus systems, while reliable, are increasingly insufficient for the massive data streams required by ADAS (Advanced Driver Assistance Systems), infotainment, and high-speed telemetry. Automotive Ethernet has emerged as the industry standard for these high-performance domains.
The PAE-Media Converter is engineered to solve a fundamental friction point in automotive development: the incompatibility between the specialized physical layers of Automotive Ethernet (100/1000BASE-T1) and the standard, ubiquitous RJ45-based Ethernet (100/1000BASE-T) found in laboratory PCs and diagnostic equipment.
Technical Versatility in a Compact Form
The device is not merely a signal bridge; it is a sophisticated diagnostic tool. Housed in a robust aluminum chassis (145 x 61 x 46 mm), it is built to withstand the rigors of harsh automotive testing environments, maintaining operational integrity across an extreme temperature range of -40 °C to +85 °C.
Key technical specifications include:
- Dual-Speed Support: Selectable 100/1000BASE-T1 conversion via an intuitive DIP switch configuration.
- Unified Connector Architecture: Integration of both H-MTD and MATEnet standards in a single unit, eliminating the need for bulky, unreliable adapter cables.
- Physical Layer Control: The ability to simulate real-world faults through link interruption, either via manual triggers or API-driven automated test scripts.
Chronology: A Strategic Evolution Toward Automotive Ethernet
HMS Networks’ entry into the Automotive Ethernet space is the culmination of years of expertise in industrial communication. To understand the significance of this launch, one must look at the trajectory of the PEAK brand and the broader HMS ecosystem.
- Pre-2024: PEAK-System Technik (now under HMS) established a dominant reputation for reliable CAN bus and LIN bus hardware. The industry viewed them as the "gold standard" for in-vehicle network (IVN) diagnostic tools.
- 2025: HMS Networks recorded a fiscal milestone of SEK 3.6 billion in sales, bolstered by a strategic shift toward Industrial ICT integration. Internal R&D departments began prioritizing the convergence of Industrial Ethernet and Automotive protocols.
- Early 2026: Engineering teams identified a critical bottleneck: automotive developers were struggling with "adapter fatigue"—using multiple, fragmented converters to test different vehicle segments.
- June 2026: The formal announcement of the PAE-Media Converter. This launch marks the first time the PEAK brand has officially moved beyond traditional fieldbus technology into the high-speed Ethernet domain.
Supporting Data: Why Automotive Ethernet Matters
The transition to Ethernet-based architectures is not just an incremental improvement; it is an architectural necessity. According to industry research, the average number of Electronic Control Units (ECUs) in a vehicle is decreasing, while the complexity of data processing is increasing. Automotive Ethernet provides the necessary bandwidth—ranging from 100 Mbit/s to 10 Gbit/s—to handle raw sensor data from LiDAR, high-resolution cameras, and V2X (Vehicle-to-Everything) communication.
The Problem with Traditional Testing
Before the PAE-Media Converter, automotive engineers often relied on "home-grown" or fragmented solutions to connect their test benches to the vehicle’s network. Common issues included:
- Signal Degradation: Poorly shielded adapters introduced noise, leading to "false positive" errors during link-up.
- Hardware Complexity: Multiple converters meant more power supply requirements and increased physical footprints in test cabinets.
- Software Incompatibility: Many converters lacked an API, preventing them from being integrated into automated "Hardware-in-the-Loop" (HiL) testing rigs.
The PAE-Media Converter addresses these by providing a "Plug-and-Play" experience that allows for immediate validation without the overhead of complex software drivers, while simultaneously offering the hooks necessary for enterprise-grade automation.
Official Perspectives: Empowering the Engineer
Kristofer Koch, Product Manager at HMS Networks, emphasizes that the product is a direct response to the "real-world" challenges faced by developers.
"We empower engineers with simple and powerful tools," says Koch. "With our unique physical link interruption functionality, we enable them to create real fault conditions in test scenarios without physically unplugging the device—saving time and significantly reducing wear on connectors and cabling."
Koch notes that the integration of H-MTD and MATEnet is a game-changer for lab managers. "With only one device, we cover the two de facto connection standards in the market. There are no additional adapters needed. It is a streamlined approach to a previously chaotic part of the testing workflow."
Looking toward the future, Koch frames the PAE-Media Converter as a strategic opening move. "Automotive Ethernet is a key technology for software-defined vehicles. With our strong background in CAN, PEAK has long been a proven expert in IVN communication. By extending this expertise to Automotive Ethernet, we are now providing a bridge for engineers to navigate both worlds. This is just the first step; there is a lot more to come."
Implications for the Industry
The release of this device has three primary implications for the automotive testing sector:
1. Accelerated Development Cycles
By simplifying the connection between diagnostic tools and the vehicle’s internal network, HMS is removing a major "bottleneck" in the development of ADAS and autonomous driving software. Engineers can spend less time troubleshooting their test bench and more time validating vehicle features.
2. Standardization of Test Equipment
As the industry moves away from proprietary, bespoke testing setups toward standardized Ethernet-based communication, the availability of professional-grade tools like the PAE-Media Converter will help smaller Tier-1 and Tier-2 suppliers compete with larger OEMs. It levels the playing field by providing affordable, high-end diagnostic capability.
3. Increased Reliability in Automated Testing
The inclusion of an integrated frame generator and API support signals a shift toward fully autonomous testing environments. In modern development, testing must run 24/7 to keep pace with agile software development cycles. A device that can simulate faults on command without human intervention is a critical component for these "lights-out" testing facilities.
Conclusion: A New Chapter for HMS Networks
The PAE-Media Converter is more than just a piece of hardware; it is a symbol of the automotive industry’s transformation. As vehicles become increasingly defined by their software, the lines between industrial networking and automotive communication continue to blur. HMS Networks, with its extensive pedigree in both fields, is uniquely positioned to lead this convergence.
By combining the rugged, reliable design philosophy of the PEAK brand with the high-speed requirements of Automotive Ethernet, HMS has provided a essential utility for the next generation of vehicle development. As the industry moves toward a future of fully autonomous, interconnected transport, the ability to test, validate, and troubleshoot these complex networks will remain the most critical challenge—one that HMS Networks is clearly prepared to help solve.
For engineers on the front lines of this technological revolution, the PAE-Media Converter represents a promise of stability and efficiency in an increasingly complex world. As HMS continues to roll out its Ethernet roadmap, the industry can expect to see further integration of diagnostic, analytical, and connective tools designed to keep the Software-Defined Vehicle on the road to success.
