Title: KK 2.0 Setup Reciever Issues NO SIGNAL help!
Post by: ruhul786 on May 11, 2014, 06:55:18 PM
Hello,
I am trying to fly my quadcopter x525 using kk 2.0 and FrSky D8R-II PLUS and turnigy 9xr and FrSky DJT 2.4Ghz but when i go to receiver test mode ,there is no signal except aileron
and when i move right stick aileron value change only though i connected first channel (aileron) to the first slot, the second channel (elevator) to the second slot, the third channel (throttle) to the third slot , the fourth channel (rudder) to the fourth slot and the fifth channel (auxiliary) to the fifth slot but no signal :confused:
please see this following link

Any help would be greatly appreciated.
Regards

How have you connected the receiver to the kk2 board? The signal wires should be towards the screen. Post a pic of the connections if possible

Friend the signal wire(white or yellow one) in both cases i.e. ESC connections and receiver connections should be towards screen.

First 2 servo extensions are 3 wires and rest of them are 1 wire ( aileron and elevator ) .i uploaded some pictures
I noticed when I connected 3 wires servo and when I move left stick it does change elevator value up to 5
Before it was no signal.What should I do now.
Looking forward to hear from you
Many Thanks

Right now i don't have any spare servo cables i will get on Thursday.I had one spare servo extension cable
when i connected i got elevator signal .
Looking forward to hear from you
Many Thanks

Hi, I hope you are opening many threads for the same thing. Please stick to one.
Now, you need atleast two servo extensions for connecting your receiver to the kk board. One goes to channel1-aileron on both normally. The other cable has to be connected vertically only on the signal pins. So, you can make 3 connections(elevator, throttle, rudder) from one cable only.

In the closeup of the KK2 board, I noticed that the 3 wire servo extensions are fine, but you have connected the single wire black leads on the outer pins. As I said before, all signal wires should be towards the screen. Shift those black wires on the pins towards the screen. Even on the receiver side, those wires are connected to the ground pins. Keep the black wires on those pins where the signal (or white) wire of the 3 wire cable goes. You are currently only connecting the ground pin of the receiver (for channel 3, 4, 5) to the ground pin of KK2. So shift those wires on both sides.

Hi,
In your case its only the wrong connections. Please go through very carefully now.
A small briefing first, please keep the receiver and KK2 board before you to have a better understanding. The order of the three wires in your receiver is signal(W), VCC(R), ground(B) where signal comes on top and ground should be on lower side of receiver. Now comes the KK2 board. Here, also order remains same but thats the mirror image. So now, its like signal(w) facing screen or near screen, VCC(R) in middle, and ground(B) on the outer edge. It could be easily understood on the KK2 manual available at HK(hobbyking) website.
Since, I hope now you are familiar with the connections, now comes connecting your board to receiver. I could see two jumpers with you. You need only those two for making connections, just be very careful while making connections.
The receiver is powered with the help of these jumpers through KK2. So, the first jumper has to be connected to the aileron channel both in receiver and KK2. Be sure of making connections and the pins.
"Black wire would got to outer edge of KK2 and the other end would go to lower side of receiver in the aileron channel. Similarly, red wire in
middle in both and white wire would come on top in receiver and towards screen in KK2." Now since, you're done with aileron jumper so comes other ports as well. Now you need to connect elevator, throttle and rudder.
This is done by connecting the three pin jumper vertically in both(Rx and KK2). These connections are to be made only on signal pins and it would be like signal wire(w) would go to signal pin of elevator(in Rx) and other end to signal pin of elevator (in KK2), VCC(R) wire would go to signal pin of throttle(in RX) and other end to signal pin of throttle(on KK2) and ground(B) would go to rudder on both similarly.

Thank you very much for your help. Really appreciate it. {:)}
I got all the signals now ( Aileron,Elevator,Throttle,Rudder and Auxiliary ) only problem is  rudder channel value always stay negative e.g. -5, -1 etc. So i did change my controller setting (turnigy 9xr ) i went to limits mode and changed channel 4 value 0.0 to 0.5  ;D and i got positive value (i hope i did right thing ? )
Right now motors are working when i turn on my controller and then i turn on kk board .Its shows armed and that time motors works
but if i turn on kk board first then controller then kk board shows error no yaw input ? could you please explain it to me why it shows error when i turn on kk board first. Also i noticed when i move my controller sticks 4 motors doesn't work together ? (1/2 at a time )
if i am not mistaken 4 motors should works together isn't it? although i did set up motor layout to quadcopter x  ???
Looking forward to hear from you .
Regards
Ruhul

So finally you got all signals. :thumbsup: :thumbsup:
Now since rudder channel is having negative number for that you can adjust it to 0 by adjusting rudder trim from your transmitter and its done. Second thing you mentioned is not clear. On connecting battery does it shows ARMED or you yourself arm your board(by shifting rudder stick bottom right). The correct procedure is always first turning your transmitter on and then plugging in battery.
Also, since your motors are not working together kindly recalibrate your ESC's. I hope you are familiar to this. Before calibrating do not give throttle.
I think  you should go through youtube and search for: Die hard RC  addicts SK450 quadcopter part 2 setting up.
This is very helpful. I'm sure you'll get all your answers here.

Thank you my friend .I did check that youtube video and i follwed their instruction with regards to ESC calibration but unfortunatley after 2 beeps when i move throttle down it shows ESC Calibrating and nothing happen.I hold first and last button more then 5 minutes but nothing happen.I noticed when i go to receiver test or kk board setting mode 3 motors move except 1 motor.I guess that motor is not working therefore ESC Calibration isnt working .What do you think ?? even yesterday when it was armed 4 motors was working though it wasn't working together.
Looking forward to hear from you :-(

Check the motor/esc individually whether they are working fine by connecting directly to RX.If they are working fine, then you can calibrate them individually with RX and then connect them to KK board.

Thanks for your comment .I can also check with multimeter also isnt it ? for example please see this video (just to confirm )

Thank you guys ,now that motor is working ,cable connection was lose that's why it didn't work before.However 4 motors are working fine when throttle full upward but my quadcopter doesn't lift off ,any suggestion
please check my video
