PP Joy Radio control Interface (Workshop from
Wolfgang Kracht)
For my first trials I had downloaded the free FMS and used a Thrustmaster FireStorm
Dual USB Joypad. The next step was to buy IPACS Easyfly bundle with a Game
commander (identical to GameBird). The Game Commander must be connected to the
analogue Game port of the PC. Because the onboard game port of my PC was not very
accurate and so the helicopters have been nearly unflyable. The wish to have a original
radio control for simulator came up, because I also wanted to use Dual-Rate and Expo.
While researching the web I found an easy interface for the FMS, but this didn’t work with
Win 2000/XP. Then I came to the “Smartpropo” driver, which only supported JR and
Futaba PCM signals.
The ingenious idea to input the signal via the soundcard of the PC doesn’t make sense
with PPM signals, because when the soundcard has 48Khz sampling rate you only get 48
steps with an impulse length of 1ms. This let me expect an even worse solution than with
the Gamebird.
Then I found the parallel port joystick emulation “PPjoy” from Deon van der Westhuysen.
I have asked the author if he would agree to extend his driver with a PPM decoder. Deon
already had implemented this and was looking for some voluntary testers.
Already the first beta version provided great resolution and was very stable. The
interface cable of my Multiplex mc3010 is very easy and Deon’s driver is freeware.
Because the driver simulates a real game devise on the PC it works with all programs
that support a joystick.

Configuration PPjoy for PPM radios with Windows XP:
Disclaimer:
Any liability for the function or damages caused is excluded. All modifications on your
PC or radio are on your own risk!!
Configuration of the printer interface:
This explanation might look long and complicated, but it really isn’t. I only tried to
explain it in detail, so also inexperienced users can follow it.
To use the PPM-decoder of PPjoy you must make sure, that XP has allocated the IRQ for
the LPT directly (normally IRO7).
Got to the system panel and open the device manager.
