Here's how I did to make my Multiplex Cockpit MM work with FMS, RFg2 and RC plane master.
1. First I made a cable to the MIC connection in my computer.
You can find all the schematics here.
2. For FMS I just copied in the winmm.dll file to the FMS directory. You can get the file from here
3 For RFg2 it was a little harder.
First you have to install the PPjoy program, which will create a virtual joystick, get it here
Then get the PPJoydll program. With this program you load the same Winmm.dll file that you use for FMS, get it here
Start the PPJoy program and create a virtual joystick.
Start the PPJoyDLL program and load the winmm.dll file, don't close the PPJoydll program,
check your gamedevices in the controll panel and properties for the virtual joystick.
You should se movement on the bars when you move the sticks on your TX.
After that you propably have to remapp the controlls for your TX in the PPjoy program.
My problem in RFg2 was that it only used 3 Axis from my sticks and 1 slider as the fourth Axis. After some trial and error remapping in the PPjoy program I got it to work. you can find a screenshot here
To be able to fly Plane/Heli these axis have to work.
X/Y Axis, Z rotation and for me the first slider (with A3), since RFg2 uses this for the fourth Axis.
I would like to Thank Sekiriki for the excellent Winmm.dll file and also Thank Deon van der Westhuysen for making it possible for us with PPM TX to use these in flightsims.
