Hi all,
After some power failure my Dahua lost settings. I set all over again, but I noticed that P2P stop working. The reason is that serial number is now empty (00000000000), as you can see in pictures.
I found similar topic on forum, so i I try connect UART to my recorder, to set SN.
I soldered wires TX, RX and GND to junction described "232", as you can see in pictures, set com baudrate to 115200.
When device is booting up I get log, which says "Hit any key to stop autoboot: " and count from 3 to 0.
When counting I try to send via UART <CR> "Enter key", space key and any other, but nothing works, device is still going to normal boot.
I know that TX of my interface is working, because when i loop TX and RX I get echo of my sent messages.
I tried with Putty, RealTerm, Hercules etc. I tried with 5V and 3.3V. Also try change TX and RX, also tried connect TX to 4th pin in junction "232" but this is nonsense, because i think it is just power supply (DMM shows 5V)
I also tried with keyboard connected to USB of device, but still canot stop autoboot.
Full log also attached.
Have you any ideas?
Thanks in advance for helping me,
Damian
