ZC LIN Consistency Testing Service

Introduction

LIN bus is widely used in the automotive industry, covering many application fields such as window control, seat control, mirror control, sunroof control, and light control. The LIN bus has the characteristics of low-speed, master-slave communication and single-wire transmission. The master node bears important responsibilities of communication scheduling and network management, and the correct response of the slave nodes is also crucial. Therefore, in order to ensure the reliability and stability of LIN communication, it is particularly important to conduct protocol compliance testing between LIN master node and slave node.

The purpose of the LIN bus is to be low cost, but in the field of testing, LIN tools are rare and expensive. The reason is that the market is small and most suppliers are unwilling to develop Lin test tools, resulting in extremely limited selection of test tools and expensive. Moreover, across the industry, most LIN-related tools are application-level tools. They can only realize the sending and receiving of LIN messages, and are powerless to test in fields such as physical layer and network management.

In response to the problems described above, ZC can provide a complete set of Lin compliance testing solutions to solve customers 'worries.
