phoenix dongle /R7

[buzzcut44]

Tell me where I went wrong.
I used a R7 receiver set to PPM positive 20ms output and phoenix dongle.
I cut the stereo jack off the dongle and soldered the white wire as signal and red as ground to a servo lead. Connected on sat1
Powering receiver with battery.

Now here is the weird part. Phoenix says transmitter not connected
unless I'm pressing on the servo output pins with my finger. found that by accident.
I assume I'm grounding something.
It works correctly when pressing on the servo pins so I know I have missed something simple.
Let me know what you think

Maybe the two wires are reversed...

I see in the PDF file you coonect the red cable from the usb cable and the Black and white cable from the cable that would normaly go to the transmitter.
How did you identify the cables inside the box? Mine are sealed with apoxy, or did you just strip the cables outside the box and make the connections there?

Not all units are identical.

Some are covered in that black compound more than others.

Mine is essentially solid-state.

I put it back in the box and got a cheap all-in-one dongle from some Chinese site instead.

Mine is pretty heavy with the apoxy.
Would doing the white and black connection on the TX cable and powering the receiver wiith a battery work?

Well, if you do manage to cut into the cables, I would eliminate the use of a battery.

No point in having one, when there's 5v coming in through the USB connection.

So Red wire from USB cable side to red wire in your servo connector.
Black wire from anywhere to black wire in your servo connector.
and White wire (signal) from TX cable side to white wire in your servo connector.

See if you can just scrape some epoxy and insulation off the wires, enough to expose the actual wires, and tin those points. Then put a ready-tinned servo cable in there and solder in place.

I could not get it to work as the drawing shows and still does not work
Im going to be as clear as i can
I did cut wires back from each side of dongle box.
So i will say usb side for before the dongle and rx side for after dongle just because there are the same color wires used.
Red wire from usb going to rx(power 5.1v)
Rx side of dongle white wire is signal ( thats the tip of the stereo plug.)
There are 3 wires on the rx side of dongle one signal (white)
One red wire (jeti web site says that is ground, middle part of stereo jack)
Last is shielded stranded wire surrounding red and white wires.(Inside part of stereo jack)
Here is where one of the problems are. I only have two wires to choose from.
If i hook up red wire from usb ( 5v power)to rx center pin on servo connector and red wire as ground from rx side of dongle to ground pin i get no power to rx.
If I hook up the shielded wire to ground on servo connector (red wire not connected) I get power to the rx BUT the dongle is no longer recognized by phoenix as being plugged in. So shielded wire has to be a ground for usb

Now if i unhook usb power and use red wire from rx side of dongle for ground and power rx with battery the sim will see the dongle as connected but not the transmitter UNLESS(and i dont understand it) im holding on to that loose red wire coming from center pin of the rx( the one that was connected to usb side but is now not connected to anything) everything works as long as i touch that wire.
I cant explain it but let me know what u think.

I will take some photos later today.

Have you tried PPM negative, that's what I had to use when I made my RealFlight dongle.

My bet is that PPM negative with the signal and ground wired as per the PDF in this thread would work.

[buzzcut44]

I got it figured out. All works as it should. Thank you to all who helped.

It is PPM negative
Also need to tie red wire and shielded ground to ground servo wire.
Also the usb side red (5.1v ) is connected
Whoo i can sim again

I can't seem to figure out this wireless sim with the Jeti. I soldered up a usb dongle with a R4L receiver and bound it to my tx. I'm using RF and after I match up the channels I cannot get any movement. I'm set to ppm negative. What am I missing?

[myxiplx]

How do you have it wired? A photo might help us see if there's anything obvious wrong.

Here is a pic. I have the RF interlink controller.

Which port are you connecting to on the R4L? PPM out will only be possible on port 4.

Yup connected to port 4.

[dogbreath]

Remember, some port 4 is actually mislabled as port 3. I think this was on the R4L. Try it in the other port. Did it bind to the transmitter? Wherever you put the bind plug and made it work is port 4.

Yup did bind to tx with port 4.

So I went ahead and soldered the Jeti receiver jumper to the interlink controller and now I'm getting movement with my Jeti. One thing I can't seem to figure out is why I cannot lift off, it just spools up. I can see everything moving correctly. Below are my setting for tx and RF.

Servo Assign:

1 Throttle
2 Roll
3 Elevator
4 Pitch
5 Yaw

RF Channels:

1 Throttle
2 Aileron
3 Elevator
4 Blank
5 Rudder
6 Flaps
7 Smoke
8 Mode

I have enabled software and dual rates unchecked. When I check them I get no spool but movement.
