Good, so it should be a PPM transmitter.
You have to make sure your cable is the correct one and that you plug it to the correct soundboard input.
You should hear a loud noise in your speakers if the above is OK.
Now, copy the correct winmm.dll file from the package posted on the FMS home page according to the read me file that is also attached to this packege.
Start FMS and select the Controls->Analog Controls->joistick interface then click on button "resources".
Do you see Joystick 1? Does is say something like SuperSmartPropo? Then FMS recognized the software.
Click OK and then on "Mapping/Calibration".
Let me know if you are OK or where you are stuck.
Good luck.
