ZD-USB Switch

ZD-USB Switch is an auxiliary device designed to connect and disconnect USB device, making it ideal for compatibility testing. It provides four host USB ports and four device USB ports, enabling switching between 16 connection possibilities. Additionally, the USB Switch provides four relay interfaces for external device testing. The host-side USB ports can connect to USB hosts such as ZD Box and ECUs, while the device-side USB ports are suitable for flash drives, smartphones, and tablets. With ZD-USB Switch, the user can manually or remotely switch USB port connections between the host and device sides for connection and access testing.

Application Range

The ZD-USB Switch can be used for automated compatibility testing of up to 4 USB 2.0/3.0 hosts and 4 USB 2.0/3.0 devices. In this scenario, users can manually or automatically monitor and adjust the USB ports connection status, simplifying the process of frequently plugging and unplugging USB harnesses and switching USB devices during debugging and testing development phase. The product also provides 4 sets of relay groupsthat enable intelligent control of switches for scenarios such as simulating power on/off control and connection/disconnection cables.
