Подключите устройство через консольный порт, почему конечная точка конфигурации не отображает или отображает искаженные символы?

After the device is powered on, the configuration end point connected through the Console port does not display information or display garbled characters. First, check: whether the power supply is normal; and whether the configuration port (Консольный порт) cable is connected correctly. If the above inspection does not find problems, it is likely that there is a problem with the configuration cable or the setting of the end point parameters is wrong. Please confirm the parameter settings of the end point:

· Baud rate: 9600

Data bits: 8

· Stop bit: 1

Parity check: none

Flow control: none

When you confirm that the end point parameters are set correctly but the fault cannot be solved, replace the configuration cable for replacement testing.
