Vector Korea (CEO Ji-Hwan Jang, Vector Korea), a global automotive, aerospace, and transportation electronic systems development software company, is supporting the smooth introduction of the automotive Ethernet standard '10BASE-T1S' network.

Vector announced the 'VN5650' and 'VN5240' interface products, which are test and verification solutions for '10BASE-T1S' networks.

The VN series products are powerful solutions that enable automobile manufacturers and component suppliers to effectively verify and troubleshoot 10BASE-T1S networks.

As digital transformation accelerates, changes in in-vehicle network architecture become inevitable.

Existing CAN, LIN, and FlexRay network protocols are still in use, but they are showing their limitations as the amount of data processing in vehicles rapidly increases along with the development of ADAS (Advanced Driver Assistance Systems), autonomous driving, and infotainment systems.

Accordingly, IEEE established the 10BASE-T1S (IEEE 802.3cg) standard, and the automobile industry is adopting it and utilizing it as a next-generation vehicle network technology.

The 10BASE-T1S standard is a single unshielded cable.It supports a multi-drop Ethernet environment that can connect up to 8 nodes simultaneously using UTP (Unshielded Twisted Pair) cables. This maximizes the flexibility and efficiency of the vehicle network.

The VN5650 is a high-performance automotive Ethernet interface that supports various automotive Ethernet and CAN communications, including 10BASE-T1S, 100BASE-T1, 1000BASE-T1, and CAN(FD), and performs multi-network simulation and analysis, high-speed data logging, and protocol analysis.

Real-time testing is possible when combined with software-based simulation.

The VN5240 is an in-vehicle Ethernet network analysis interface that supports various automotive Ethernet protocols such as 10BASE-T1S, 100BASE-T1, and 1000BASE-T1, and provides in-vehicle 10BASE-T1S communication performance monitoring, network load analysis, and debugging functions.

Jang Ji-hwan, CEO of Vector Korea, said, “Automobile networks are becoming increasingly complex, and an efficient and scalable network architecture is essential. 10BASE-T1S is a new standard that can replace existing CAN and LIN networks, simplifying in-vehicle communication, reducing costs, and providing strong competitiveness in the future autonomous driving and connected car environments. Vector will provide a powerful solution to support testing and validation of 10BASE-T1S networks and actively support automobile manufacturers and component suppliers to build a stable network environment,” he said.

The biggest feature of 10BASE-T1S, unlike the existing 100/1000BASE-T1 Ethernet that operates in a point-to-point manner, is that it can connect multiple nodes to a single network.

This simplifies the in-vehicle network structure and dramatically reduces wiring complexity.

In particular, 10BASE-T1S simplifies networks and supports cost reduction and weight reduction, Ethernet-based flexible expandability, high reliability, and real-time data transmission performance.

The essential preparatory elements for the introduction of 10BASE-T1S include hardware and network verification, test and verification environment construction, and software and protocol stack preparation. These elements must be prepared so that automobile manufacturers and parts suppliers can effectively introduce 10BASE-T1S networks.
