How to set the parameters of led electronic screen?

Determine whether the serial number of the computer is com 1.

Hardware model of hardware parameter block control card

Baud rate

Excluding com 1 is correct, then assuming the baud rate of 9600 is also correct, change the hardware model and try one by one; If all else fails, on the other hand, you have to assume that one of the hardware models is correct and change the baud rate. If not, assume that the other hardware model is correct and then change the baud rate until it is successful. After each parameter point is changed, save and observe whether the software prompt bar is "sent successfully". If all are unsuccessful, there is another possibility that the card is broken or the communication line is broken.

Generally, you can know the baud rate by looking at the control card in the electronic screen! Just change the hardware model to judge.

Only when the prompt is successful can the scanning mode and enabling level be further modified.
