I got it.
so you want to change the frame header?
The default value = 0x5AA5.

Wrong frame header is output
Where do you check?

Hi, maybe the baud rate is wrong, the baud rate of the display is 115200 or there is no ground wire or the serial port is wrong.

You can use the Terminal Assistant software to check the problem, you can send: 5A A5 04 83 000F 01

and then check the returned datas.

and you need to open the port first.

DMG12800L101_01WTC이 모델의 직렬 포트는

3.3V 레벨입니까? 오실로스코프로 측정하면 이상하게 보입니다.

Hello, T5UID3 how do I start communicating on the serial port. What should be set in cfg except for the baud rate.

You need to set the highest bit of position 08 of CFG to 1 to enable automatic data upload
