old am futaba as sim controller

[signguy]

I have an old futaba attack transmitter. I use the software, smartpropoplus ( link http://www.geocities.com/shaul_ei/SmartPropoPlus_PPJoy.html)as an interface for my OPTIC 6 through the trainer jack, and into the sound card to fly clearview. The attack has no trainer jack, but does have a seperate board just for the transmitting section. How do I go about finding the correct area to "tap into" the board? Any help is greatly appreciated!
Thanks

I modded my Attack 4. If it uses the same chip (NE5044 http://www.datasheetcatalog.org/datasheet/philips/NE5044.pdf) you can take the 5V PPM signal from Pin 11 of this chip. It goes straight into the RF stage via a resistor.
You will find some web pages detailing this further if you Google around.
You will also notice that this chip set is easily modded to give you some extra channels (max 7) so you can add extra switches to you sim

Thanks "fluffy" I'll look at the chip and see if it works...

looks like i have an OKI L9362 chip. I have looked on line, but can't find anything helpfull. I'll keep looking.....

Do you have access to an oscilloscope? If yes, it's rather easy to find the PPM signal, just probe the control chip pins. I used this method a few years ago when modding my 3CH futaba TX.

Fyr.. Oki L9362

[signguy]

would I use the OUT to modul pin, and ground? Forgive me, but I have little electronics knowledge. Also, what is the orientation of the chip in the diagram?

Found this last night(http://www.engadget.com/2006/03/14/how-to-real-controls-for-r-c-flight-simulation/) looks the same as my trasmitter guts, but still no signal to the computer. I did download zelscope, to test with, but nothing.......

Forgive me, but I have little electronics knowledge.

Then in all honesty, you should not try to convert the TX as you could turn it into a brick.

But to answer your questions, try googling L9236 that is shown in the post above. You should be able to find the data sheet to match the schematic description and work out what pins are what. This can be tricky as as more than one manufacture makes these chips, and they can come in different packages.

sign,

This is a discontinued OKI part (http://www.okisemi.com/datadocs/doc-eng/discon/msl9362_msl9363.pdf). The PPM output pin is #9.

Good luck,

Serban, good find, the schematic looks simple enough, and it should be a simple case of connecting a single core screened wire between pin 9 and gnd and terminating the other end with a 3.5mm male jack plug for his soundcard if using smartpropoplus

Thanks guys, I don't really care if I brick the transmiter, it is of little use to me without an AM reciever. And it is pre 1990 wide band 72 mhz.

I should be able to get this working now..
Again, thanks all...

It Works!!!! Thanks to all, the schematic of the chip helped out . Pin 9 is the one! thanks

If possible I would like to know if they have the datasheet of the L9362 OKI.
Thanks

Ever heard of Google ?? - nope !

I could go on but there are 311 hits for "L9362 datasheet" :rolleyes:

The L9362 is a radio Futaba attack-r and has 14 pins.http://img10.imageshack.us/img10/6303/imagem0120.jpg (http://img10.imageshack.us/my.php?image=imagem0120.jpg)
