This issue demonstrates the SV04 USB3.0 HUB switch, which has a built-in RS232 serial port control function and is very suitable for users who need to control USB devices with multiple hosts. Only a USB to RS232 data cable and a control cable are needed. After the connection is completed, the USB switch between different hosts can be completed by sending commands through the serial port debugging tool. This video shows the whole process from driver installation, connecting cables, to sending control codes (such as AA 01 55 to switch to host No. 2). SV04 supports switching between 4 hosts, with stable and fast operation, and is particularly suitable for industrial control, test platforms, server duty and other scenarios.
