The ZD AES1000 is an advanced Ethernet switch that supports the expansion of 8 * 100/1000Base-T1 ports, a development tool for testing and analyzing Automotive Ethernet in a variety of application scenarios. It allows users to physically disconnect and sequentially pass through multiple devices in vehicle networks to create virtual point-to-point connections. This resolves the issue of incompatible physical interfaces between different devices in Automotive Ethernet, enables high-speed data transfer, while supporting gPTP time synchronization. The ZD AES1000 can be used for Automotive Ethernet chip debugging, as a physical simulation node with vehicle network channels in conjunction with simulation testing software, and for debugging Automotive Ethernet sensors.
