In-vehicle network communication with seamless automotive Ethernet connectivity

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 100Mbit/s and 1,000Mbit/s domains.

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.

The device combines H-MTD and MATEnet connector support in one unit, reducing hardware complexity, investment risks, and enabling faster setups.

Kristofer Koch, Product Manager at HMS Networks, says: “With only one device we cover the two de facto connection standards in the market – with no additional adapters needed.”

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.

The PAE-Media Converter comes with a robust aluminum housing (145×61×46mm), 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 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.
