On the RS485 side DB9 connector, what are the two PINs A and B respectively? [Copy link]

As shown below, RS232 to RS485 passive converter;

The terminal board on the RS485 port side is lost.
Now I want to use a DB9 connector to directly solder two wires (that is, RS485 AB).
However, I don't know the definition of the DB9 connector on the RS485 side.

Therefore, I post this for help, and hope that the great god will give me some advice:

Question:
Which two pins are AB in the DB9 connector on the RS485 side?

Thank you so much!
