HMS Networks Introduces PEAK’s First Automotive Ethernet Solution

HMS Networks has introduced its first-ever Automotive Ethernet product under the PEAK brand, entering a new era of IVN communication. The PAE-Media Converter is a robust and compact device designed to connect Automotive Ethernet (100BASE-T1 or 1000BASE-T1) with standard Ethernet (100BASE-TX or 1000BASE-T) networks. As a media converter, it enables automotive engineers to simplify development, testing, and validation workflows within the 100 Mbit/s and 1,000 Mbit/s domains.

Unique Features for Automotive Testing

The PAE-Media Converter addresses crucial market challenges in automotive development and validation with three core innovations. It enables realistic fault simulation by allowing physical interruption of the Automotive Ethernet link. This can be triggered directly on the device or via an API, supporting reproducible and controlled test scenarios.

“We empower engineers with simple and powerful tools. With our unique physical link interruption functionality, we enable them to create real fault conditions in test scenarios without unplugging the device – saving time and wear,” explains Kristofer Koch, Product Manager, HMS Networks. At the same time, the device combines H-MTD and MATEnet connector support in one unit, reducing hardware complexity and investment risks, and enabling faster setups.

“With only one device we cover the two de facto connection standards in the market – with no additional adapters needed,” says Koch. In terms of useability, the PAE-Media Converter provides what engineers enjoy: true plug-and-play operation with optional API control and a selectable (via DIP switch) dual-speed
conversion (100/1000BASE-T1). The benefit of this hardware-only configuration is that engineers can start immediately without software, while still having the flexibility to integrate the device into automated test environments.

Designed for Practical Engineering Use

The PAE-Media Converter comes with a robust aluminum housing (145 × 61 × 46 mm) and an extended operating temperature range from -40 °C to +85 °C that ensures reliable performance in testing environments. For intuitive on-device diagnostics, LED indicators provide direct feedback on link status,
signal quality, and errors. This enables fast diagnostics without additional tools and supports efficient troubleshooting during development and testing.

Flexible Integration and Automation

The media converter easily integrates into existing Ethernet environments. It connects directly to standard tools, enabling immediate use in development and analysis workflows. An integrated frame generator supports link validation and wiring tests.

Available accessories include H-MTD and MATEnet cables for Automotive Ethernet connections, as well as a DIN rail adapter for integration into test benches and industrial setups. These components enable quick adaptation to different environments and reduce setup effort.

“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.”

Key Technical Features

The PAE-Media Converter supports conversion between 100BASE-T1/1000BASE-T1 and 100BASE-TX/1000BASE-T Ethernet standards. It offers dual-speed operation, with hardware-based selection via DIP switches, and integrates support for both H-MTD and MATEnet connectors. Power can be supplied either through USB-C (5V) or a 6–36V DC source. Designed for demanding environments, the converter features a robust aluminum housing with IP20 protection and operates reliably across a temperature range of -40°C to +85°C.

Configuration is hardware-based and requires no software, enabling straightforward deployment. For diagnostics, the device incorporates LED indicators that provide real-time information on link status, signal quality, and errors. It also includes an integrated frame generator for link validation, supports controlled link interruption for testing scenarios, and offers an optional USB API for automation and system integration. In addition, the converter is compatible with standard Ethernet tools and infrastructure.
