Protection Function: overcurrent protection and relay diode follow current protection function 2. Communication Protocol: LC USB switch defaults communication baud rate: 9600bps LC USB switch communication protocol: Data (1): start mark (defaults 0xA0) Data (2): switch address code (defaults 0x01, means the first channel switch) Data (3): operation data (0x00 is OFF, 0x01 is on) Data (4): check code For Example: Open the USB Switch: A0 01 01 A2 Close the USB Switch: A0 01 00 A1 3. Using Methods: Step 1: plug the USB relay module on the computer, and install CH340 USB to serial port chip driver Step 2: open the STC-ISP, SSCOM32 serial port debugging software, and select the baud rate as 9600. Send A0 01 01 A2 to open the relay in the form of hex, select manual send or auto send Manual Send: select the baud rate as 9600, check "HEX send"; input the instruction A0 01 01 A2 or A0 01 00 A1, then click "send"; then you can open or close the relay Auto Send: select the baud rate as 9600, click "expand" SSCOM32 interface; input instruction A0 01 01 A2 and A0 01 00 A1, check "HEX send" and input the interval time of auto cycle sending,
