The AES1000 is an Enhanced Ethernet switch that supports the expansion of 8 * 100M/1000MBase-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 cycle through multiple devices based on the vehicle network, creating virtual point-to-point connections. This solves the problem of different physical interfaces between devices in Automotive Ethernet that cannot be directly connected, and achieves high-speed data transfer, while also supporting gPTP time synchronization. ZD-AES1000 can be used for automotive Ethernet chip debugging, combined with simulation test software as a physical simulation node with Automotive network channels, and for debugging Automotive Ethernet sensors.
