Pinout of the D-SUB 9-pin Diagnostic Cable for Solaris Buses

[tonkostz]

I need the pinout for the 9-pin diagnostic cable for Solaris buses. This is a 9-pin D-SUB male connector for bus connection and a 16-pin OBD female connector for various interfaces.
I am attaching a photo of the 9-pin bus connectors to which the diagnostic cable is connected, as well as a diagram showing the pinout of the RP-01 unit connector.
