Supongo que ya lo habrás probado.
Por lo visto sólo se admite una interrupción para el puerto paralelo. IRQ 7 y I/O Port 378h. Se puede cambiar en la BIOS.
Existe un program DOS para hacer pruebas más fácilmente.
Puedes tener problemas con la SoundBlaster. Comprueba que no esté en la misma interrupción que el puerto paralelo (Aunque la soundblaster me parece recordar que siempre entraba por la IRQ 5) Como te dice el manual del cable, desconecta la compatibilidad de la sound blaster.
Quien dice la soundblaster, dice otra placa de sonido. Suelen llevarse mal si comparten interrupción con otro dispositivo.

In order for the test program to work, your transmitter must be in standard FM mode (NOT PCM) and your parallel port must be set to use Printer Port IRQ 7 and I/O Port 378h. These settings must be set in the BIOS Computer Setup which you usually access by pressing F1, F2, F10 or DEL key just after your turn your computer on, not in Windows, however after you change the setting in the BIOS you may need to remove the parallel port from the Windows Device Manager (System in Control Panel) and let Windows redetect it with the new settings. This is the default setting used on most computers. Also, this is NOT what FMS defaults to, you must manually set the lpt port to 378 inside the fms transmitter settings for it to work.
Also, if you have a PCI Soundblaster (and maybe other soundcards?) you may need to disable sound blaster compatibility in the device manager. I recently upgraded sound cards to a PCI and my interface would say "signal detected" but not show any movement. When I disabled the soundcard's SB Emulation it worked fine. Thanks to Simon on my forum who figured this out.
As you can see, I put the thing together and it really does work! It also is very simple to put together, obvioulsy.
On the futaba transmitters, the signal is the top-left pin when looking at the trainer jack (Pin 2) and the bottom middle / outer casing is the ground.
The only problems I noticed were that it was slightly "twitchy" meaning it was like I was getting radio interference. You can fix this by having shorter exposed leads and shielding the wires I'm told. It was not TOO twitchy to use so it's still a great tool and the little random acts help hone your skill of inputing the correct movements. Kind of like turbulance!
