According to the forum, I swapped the R and T jumpers. I can occasionally receive data. But more importantly! ! ! ! I connected an external MAX232 serial port module and can receive data very stably. ...
Why is the capacitance of DC12V (C1) so large?
Is it larger than the 24V and 32V capacitors below?
Is it necessary to choose such a large size? What is its function?...
