1.Plug the light into the USB port. 2.View My Computer-right-click Management, System Tools-Device Manager, double-click the port (COM and LPT), and view the COM serial port number. 3.Open the USB three-color light debugging driver-commassistant.exe (you can also use other serial port debugging tools) 4. Select the COM serial port (whatever COM number you checked in the first step, select it here), serial port baud rate: 9600, 8 data bits, 1 stop bit, no parity bit. Check the hexadecimal system, send the corresponding code on the left to the blank area (note that there are spaces in the middle of each group of hexadecimal systems), click Send, and you can control the color and buzzer. (In practical applications, customers can make their own serial port tool and automatically send codes to control the desired effect) 5. After the test is OK, close the software and unplug the USB. (Note: The status of each color can be controlled individually. After sending the control, you need to send the light-off signal again, and the corresponding color will turn off the light. The flashing frequency of all colors and buzzers is once per second.) WARNING: PLEASE CONFIRM INPUT VOLTAGE BEFORE WIRING, AND ENSURE THE POWER IS DISCONNECTED.
