Hello Omar Ahmad，
You may refer to this document. https://www.droking.com/cs/wp-content/uploads/2017/07/200220.docx
I am referring to this document. However when I write “:wu1000”, the 200220 device is not registering the voltage to be 10V.
Also in the serial monitor, when I send the command :wu1000 I just receive back the ascii value of each character.
Did you set a output voltage that higher than input?
Here are some comment by Mitchel. It may help you.
