Vector Korea (CEO Ji-Hwan Jang, Vector Korea), a global electronic systems development software company for the automotive, aerospace, and transportation industries, 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 automotive 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 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, allowing up to eight nodes to be connected simultaneously using Unshielded Twisted Pair (UTP) cables. This maximizes the flexibility and efficiency of vehicle networks.

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.

The biggest feature of 10BASE-T1S is that, unlike the existing 100/1000BASE-T1 Ethernet that operates in a point-to-point manner, 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 lightweighting, Ethernet-based flexible scalability, high reliability, and real-time data transmission performance.

Essential preparations for 10BASE-T1S deployment include hardware and network verification, test and verification environment setup, and software and protocol stack preparation. These elements must be in place for automakers and component suppliers to effectively deploy 10BASE-T1S networks.

Jang Ji-hwan, CEO of Vector Korea, said, "Automotive 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. It simplifies in-vehicle communication, reduces costs, and provides a strong competitive edge in the future autonomous and connected car environments. Vector provides a robust solution that supports the testing and validation of 10BASE-T1S networks, and we will actively support automakers and component suppliers in establishing a stable network environment."
