I'm trying to update my CK3000 EVO. no success so far. I have a TTL adapter but there are several connection schemes e.g.
or
and such a hint
With a multimeter it was quickly worked out that pins 2,4,6 are GND; 3,7,10 + 12V; 8 + 5V. This only left 1.5 & 9 to be either Tx or Rx. The 5v on pin 8 was not enough to power the TTL circuit, I am not sure what it is for. Anyway to cut a long story short here is the pinout below.
I am standing here after launching the update

In one of the hints he writes to connect the power supply (12V) after such progress as in the picture!
Someone can share a photo (relatively sharp) of a plate without a housing.
Something burned on the photo I want to determine what and how with this element?
Adds photos with functional control panel.
Now another puzzle, because the remote control can be connected in two ways, the plug is square and two protections on both sides only, which one is correct?
