Unveiling Kvaser Arcus 100/1000BASE-T1 H-MTD: Your reliable connection to Automotive Ethernet

The Kvaser Arcus 100/1000BASE-T1 H-MTD is a high-performance Automotive Ethernet media converter that simplifies access to vehicle networks. Designed for engineers and developers, Kvaser Arcus is capable of providing fast, stable, and secure conversion between 100/1000BASE-T1 Automotive Ethernet and your development workstation—ideal for lab testing, in-vehicle development, and everything in between.

Seamless connectivity

Kvaser Arcus converts full-duplex between Automotive Ethernet and Standard Ethernet, connecting the vehicle network directly to your PC or data logger. It can be installed in standard PCs using the Kvaser ATX Bracket for Arcus 100/1000BASE-T1 H-MTD (EAN 73-30130-01811-2). Powered via PoE, USB-C, ATX or SATA, this media converter is reliable between -40° C and + 85° C and handles real-world automotive testing and validation with ease.

Secure and future-ready

Kvaser Arcus provides an intuitive API and GUI for adjusting PHY settings and configurations via USB. Built with state-of-the-art security in mind, the platform is designed to align with the requirements of the Cyber Resilience Act (CRA).

The hardware is developed to align with OPEN Alliance TC17 recommendations and includes support for hardware-level features such as MACsec to enable secure automotive Ethernet communication.

To facilitate network power-management functions, the hardware is also prepared to support mechanisms associated with Open Alliance TC10 wake-up and sleep behavior.

Purpose-built for every task

Kvaser Arcus is more than a media converter—it’s a versatile, high-performance tool designed to support key workflows in Automotive Ethernet development. With its back-to-back PHY architecture and rich diagnostic capabilities, Arcus enables you to:

  • Flash ECUs over Automotive Ethernet, IP/Ethernet-based protocols, by connecting a vehicle network to a development PC
  • Access link-level information for debugging tasks using PHY-exposed parameters such as link status, speed, and signal quality.
  • Transmit crafted Ethernet frames for testing ECU behavior, link robustness, and protocol handling.
  • Evaluate secure communication behavior by observing MAC-layer characteristics and checking resilience to invalid or unexpected traffic.
  • Verify cable integrity using SQI (Signal Quality Index), BER (Bit Error Rate), and built-in cable diagnostics to detect shorts, opens, and pair mismatches.
  • Support testing of partial networks by allowing a PC application to emulate expected link activity when an ECU is not present.
  • Check early-boot communication sequences between ECUs and bootloaders during initial system start-up
