Instructions
Communication protocol description:
LCUSB switch default communication baud rate: 9600BPS open USB switch: A00101A2 turn off USB switch: A00100A1 query switch status:
FF LCUSB switch communication protocol:
Data (1) - Start ID (default is 0xA0) Data (2) - Switch address code (default is 0x01, identify the first switch) Data (3) -
Operation data (0x00 is " Off", 0×01 is “on”) Data (4)---Check code

Instructions for use:
1. Plug the USB relay module into the computer and install the CH340USB to serial port chip driver. 2. Open the serial port
debugging software such as STC-ISP and SSCOM32. Select the baud rate to be 9600 and send it in hexadecimal (hex) format. A00101A2 turns on the relay; sends A00100A1 to close the relay in hexadecimal (hex) form, you can choose to send manually or automatically. The following is an example of SSCOM32 serial debugging software:
