Problems solved by technology

[0002] With the increase in the number of electronic control units (Electronic Control Unit, referred to as ECU) and sensors in vehicles and the increase in data volume, the demand for in-vehicle network bandwidth is also increasing. The original in-vehicle network, such as: controller area network (Controller Area Network, referred to as CAN), local interconnection network, and vehicle network standards have been unable to meet the needs of high-speed transmission of large data volumes such as advanced driver assistance systems, audio-visual entertainment, automatic driving, and Internet of Vehicles. Therefore, automotive Ethernet is used in vehicles more and more widely used
[0003] When developing and debugging vehicle-mounted Ethernet-related equipment and systems, vehicle manufacturers and equipment suppliers need to connect a personal computer (PC) to the vehicle-mounted Ethernet, and the interface of the vehicle-mounted Ethernet is a single-pair twisted pair. It is not the 8-wire Registered Jack (RJ) 45 connector interface of the traditional Ethernet, so that the vehicle Ethernet cannot be directly connected to the PC, which brings great inconvenience to the development and debugging
