Just wondering if there is anyway I can determine the UART pinout from looking at a UART with the 4 pin mini molex connector. I'm trying to unbrick and the hit and miss approach is not working. I can only get scrolling gibberish trying RX from 1st pin left side and RX from 1st pin right side - so I want to at least be confident that I am working with the correct pin out. My camera is a new Dome PTZ (DH-SD22A204TN-GNI)... Any help appreciated. Been struggling with this quite a while now
