Configuration for Multiplex Adaptor to Phoenix Tongle

[HotDogBun]

Anyone has the digram for Multiplex adaptor to audio jack configuration for Phoenix Simulator?

I found one for Realflight G4, not too sure if it is suitable for Phoenix.
It states
Pin 4 - Signal
Pin 2 - Ground

Anyone can verify this?

Thanks

Cant seem to get it to work. Anyone using MPX transmitter for Phoenix? Can help check your adaptor is using which 2 pins for the ground and signal?
