Status: offline 		Hiya all, I have the Dragonfly 22E with the 6 ch controller and i want to make up my own sim cable to connect the transmitter to the PC.

On the back of the Transmitter it has a S-Video 4 pin plug so i want to find a diagram for the wiring of this. I want to build my own

I have to use a S-video on controller end and DB9 on the other,.

Any Help would be appreciated, even a wiring diagram or pinouts

Thanks

JAs

Status: offline 		Hi Jaskel
I am having similar problems A) I am having trouble finding the cable in the first place since I bought the helo from China B) I have heard other people complaining that they can't get it running on their PC's either. Did you happen to come up with a solution for this?
Cheers
Steve

Status: offline 		yes i did find a solution...I built my own...here is a paste from another thread it did;

--------------------------------------------------------------------------------

Ok with some help from RC&Me yesterday I got my walkera TX working on realflight G2.

Ive got some photos below to help yall build your own cable and have it working on g2.

OK, first up you need to figure out he SIGNAL wire and the GROUND Wire;

The SIGNAL Wire is the wire that is looking at back of transmitter, will be bottom left

The GROUND wire is the wire that is looking at back of transmitter, will be top right




Ok every S-Video Cable will be different interms of color of wires inside so just find the correct pin and trace the wire to the end you have cut.



Next solder a 10K resistor from PIN 10 to PIN 16 on the DB25



Then Solder The 2 legs of the transistor to PIN 18 and PIN 10 (with one side of the resistor)

Fold the centre leg on the transistor up ready for the signal wire and 10K resistor.

Solder a 10K resistor to the transistor leg you bent around.

Next job is to solder the Signal wire to the resistor that is connected to the transistor base.



Then Solder the GND line to the PIN 18.



Connect your casing of the DB25 and your done....



Then you will need to go to PPJOY and configure a new LPT1 controller and select Radoi TX go thru the setup it will install drivers etc

You may need to go into your bios and setup the LPT1 to EPP then reboot and also make sure in device manager that the LPT1 is set to interupt always.



The just go into realflight G2, select the LPT1 controller and select CUSTOM configuration and you are done...



You may need to configure and calibrate all channels to the ones you need like elevator, rudder etc...mine is working a treat.





I hope this helps as I know there is alot of frustrated people trying to get the Walkera TX working like this. SPREAD THE WORD!!

Big thanks to www.rcandme.com for his help, cheers Tim. This guy has all the parts for the walkera choppers and is a walkera agent. Check it out.

Status: offline 		I got a cable with my 22e right in the box with a 9 pin serial connector. I have had so much trouble with G2 sim that I gave up trying to run the program period. Too bad I used to really enjoy that sim.I have one of the early generation G1 and G2 great planes flight simulator

I've been looking for the sim cable for ages!!!
But may I know what is this (as shown with circled in red)?

By the way, does this work with WinXP?

The pins are as marked in the photo earlier in this thread.

If you want to use FMS, then use PPJOY to convert. Same circuit as above.

Once you do this, the control sequence under FMS is 4,2,3,1 with 2,3 and 1 inverted.

Hi David,

Does this cable, as shown by Jackel, work with other sims and WinXP?

Thx.

Yes, it does.

As long as you use PPJOY, the TX becomes another HID (Human Interface Device) under XP.

Although the controls are a little messed up by default, if you play with the settings under PPJOY and remap the axis, then your TX works just like a normal joystick.

Well, 2 joysticks... X,Y,Z and Rudder. You can use it with any games under XP - even non-flight-sims,

David

Status: offline 		Hi David,

I had made myself the cable but with the different transister, 1W 10 omhs.
I tried to follow your set up but I realised that I didn't have the G2 but the G3 only...
Where I can download the G2 from?

I can't get this to work with the FMS neither....
HELP!!!

HELP!!!HELP!!!HELP!!!

They look like 10K Ohm resistors to me.

What sort of transistor did you use?

Also, are you using PPJOY? It won't work without it.

eg, http://www.simtel.net/product.download.mirrors.php?id=75176

Status: offline 		Hi mate,

Yeap, it's the 10K ohms resister as you have mentioned.
But I believe the blue one you have is 1/2W, right?
I couldn't get the 1/2W nor 1/4W, so i got the 1W.
Would that be the problem?

I have the BC548 resistor as you have mentioned.

Umm, can anyone gives me the link where I can download the G2?
Please...

Well, I did follow the instruction to do the set up.
But it's not beeping when I got to here...
It said "error 5 opening port" and "error 2 opening port when I tried COM1 and COM4...
Did I do something wrong???
