2024-07-12 15:04:05 There are two methods:
1. Select a COM port randomly on the computer, and then send characters randomly. You will see the corresponding indicator light on the right side light up. At this time, you will know which port it is.
2. Install the RainbowLink driver. There will be four ports, A, B, C, and D, in the COM list, corresponding to the A, B, C, and D ports on the panel respectively.
