An Automotive Ethernet media converter is now more critical than ever as the automotive industry rapidly shifts toward software-defined vehicles (SDVs). To meet this growing demand, HMS Networks has officially launched its first-ever Automotive Ethernet product under the highly regarded PEAK brand. This release marks a significant milestone in in-vehicle network (IVN) communication, offering seamless, robust connectivity across divergent network architectures.
The newly introduced PAE-Media Converter acts as an essential hardware bridge. It connects standard Ethernet configurations ($100\text{BASE-TX}$ or $1000\text{BASE-T}$) directly with specialized Automotive Ethernet protocols ($100\text{BASE-T1}$ or $1000\text{BASE-T1}$). Designed as a compact and highly durable tool, it enables engineers to streamline and simplify complex validation, diagnostics, and testing workflows across both 100 Mbit/s and 1,000 Mbit/s bandwidth domains.
Overcoming Critical Engineering Bottlenecks in Automotive Testing
Modern automotive development requires rigorous validation processes to guarantee the safety and reliability of electronic control units (ECUs). The PAE-Media Converter addresses these engineering bottlenecks by introducing three core innovations designed for modern test benches.
1. Controlled Physical Link Interruption
A standout capability of this hardware is its support for realistic fault simulation. Testing communication robustness requires engineers to understand how a system reacts to intermittent cable disconnects or signal dropouts. The PAE-Media Converter permits physical interruption of the Automotive Ethernet link without requiring anyone to physically pull out a cable. This interruption can be triggered manually via on-device controls or integrated into automated testing sequences via an optional USB API.
By eliminating manual handling, test laboratories can execute highly reproducible, precise, and automated fault scenarios. This reduces physical wear and tear on expensive test equipment and significantly accelerates validation timelines.
2. Dual-Connector Integration Without Adapters
In the automotive market, two physical connector formats have emerged as de facto industry standards: H-MTD and MATEnet. Traditionally, testing facilities had to maintain distinct sets of conversion hardware or rely on signal-degrading intermediate adapters to switch between them.
The PAE-Media Converter resolves this hardware fragmentation by combining both H-MTD and MATEnet connector support into a single native unit. This unified design minimizes investment risk, optimizes lab space, and ensures rapid configuration switchovers.
3. Pure Plug-and-Play Hardware Configuration
Engineers frequently lose hours configuring drivers, flashing firmware, or resolving software compatibility bugs on test benches. This new device emphasizes a hardware-first philosophy. Speed selection ($100\text{BASE-T1}$ versus $1000\text{BASE-T1}$) is handled instantaneously via physical onboard DIP switches.
This standalone design allows teams to deploy the device instantly out of the box. For advanced automation setups, the optional software API remains available, striking a perfect balance between simplicity and complex system integration.
Built for Demanding Test Bench and Field Environments
Beyond its advanced electrical architectures, the hardware is explicitly engineered to survive harsh industrial and automotive test environments.
- Thermal Resilience: It operates reliably across an extended temperature spectrum ranging from $-40\text{ °C}$ up to $+85\text{ °C}$.
- Form Factor: Housed in a robust, space-saving aluminum enclosure measuring $145 \times 61 \times 46\text{ mm}$ with an IP20 protection rating.
- On-Device Visual Diagnostics: Integrated LED indicators offer real-time, visual confirmation of active link statuses, network errors, and signal quality metrics, making troubleshooting instantaneous without requiring additional diagnostic software.
- Versatile Power Delivery: The device accommodates flexible power layouts, drawing juice via a standard 5V USB-C interface or alternative industrial DC power inputs ranging from 6V up to 36V.
“Automotive Ethernet – especially within the 100/1,000 Mbit/s domains – is a key technology for software-defined vehicles”, says Koch, highlighting PEAK’s strategic move into this emerging market. “With our strong background in CAN, PEAK has long been a proven expert in in-vehicle communication. With the addition of Automotive Ethernet, we are now extending this expertise to cover the full IVN landscape. For engineers, this means one reliable partner across both technologies. With the PAE-Media Converter, we provide a first simple yet powerful tool to bridge development and testing environments – with a lot more to come in the future.”

The Strategic Leap Toward Software-Defined Vehicles
Automotive Ethernet serves as the foundation for the next generation of zonal architectures and central computing platforms within software-defined vehicles. High-bandwidth communication is mandatory for routing sensor data from advanced driver-assistance systems (ADAS), high-resolution cameras, and infotainment platforms.
As an established leader in legacy in-vehicle networks like Controller Area Networks (CAN and CAN FD), the expansion of HMS Networks’ PEAK brand into Automotive Ethernet rounds out its diagnostic ecosystem. Technical teams can now rely on a unified partner to bridge legacy bus architectures with high-speed, modern Ethernet infrastructure.
