RX and TX KESS V2 UART Wiring Connection

Just about UART pinout / connections on RX KESS v2 and TX KESS v2 with USB adapters …It seems to have differences between the connections…

Puzzle:
In a thread, i can see that:
RXD become TXD then TXD become RXD And to finish the link between 1 and 13 pins become 1 and 25…
Am i wrong?
If i’m right which are the good connections?
Uart Connection

Another one

User solution:
RX and TX unit KESS V2 the reverse at USB adapter.
Connect RX KESS v2 to TX USB Adapter, TX KESS v2 to RX USB adapter.
Especially on my picture in the upper left corner of the photo adapter and connector db25.
Pin 1 should be shorted to Gnd.

Note: TRY ON YOUR OWN RISK
