Anyone know how to connect a Twister to FMS?

[jonny5]

er, as the title suggests, I'm trying to connect my Twister TX to FMS. I've tried the method using the microphone socket on my soundcard but it doesn't work. I want to connect it to my parallel port, does anybody know which pins to connect to where?

Cheers

What I would suggest you do is get a jack socket to fit your male end.

Then take leads off this to feed into a parallel socket.

See here to see where and how to connect up.

Thanks for your help. Do you know if the pins used for the microphone connection method are the same ones I need to use for the parallel port connection?

You'll have two connections from the pin, this will transfer into the jack socket then you need to take the feed from the jack and wire it into the parallel using the diagrams given on the linked site.

I can't 100% say this will work, but I can't see a reason why it shouldn't, all your doing in effect is converting the connection from a pin to a parallel without loosing the pin, should you need it for other purposes.

I hope this makes sense.

I tried this method over the weekend, and the method suggested in the FMS manual but neither worked. I don't know what I am doing wrong?

I have Win98 and 2K on my PC but can't get it to work with either.

On Win 98 I am setting the controls to parallel port (I think it's the 16 bit option) and setting the IRQ to 7 and the address to 378 but it still doesn't work.

On Win 2K I don't get the parallel port options at all. I haven't yet tried the PPJOY software, is this the answer? I have tried disabling my sound card too but that didn't make a difference.

Have I missed a setting that I need to change?

I have seen a cable in my local model shop but it's very expensive for what it is, especially as I am capable of making my own - if only I could get the thing to work!!

How do I check that I am getting the right signals from my transmitter and from the parallel port? I have access to an oscilloscope and a DVM but don't know what the signals should look like.

All help appreciated, I'm desperate to get going!.

It would help if I knew the difference between the ground and signal connections - I had them the wrong way round!

Thanks for all your help.
