Hello, i have an octocopter made by me.
The octocopter have:
- A2 flight system;
- 2.4G Bluetooth Datalink;
- IOSD Mark II;
- Graupner MZ-24 transmiter / GR-24 receiver for the drone operator;
- T14SG transmiter / R7008SB receiver for the gimbal operator;
- Lightbridge for gimbal camera;
- ImmersionRC 5.8Ghz transmiter / Uno 5800 receiver for drone camera;
- Gimbal made by me with a alexmos 32 bit board.

The problem that i have is:
I want to transmit hd image from the gimbal camera with lightbridge.
I had connected the camera with HDMI cable and the lightbridge air system Power and CAN cable. (like DIY mode that is in the manual)


Do i have to connect the DBUS cable in the air system to X2 port in A2 flight system? My A2 X2 is already in use with the D-BUS adapter that is connected with the graupner GR-24 receiver. So do i have to connect DBUS cable? If yes, where? since i don’t have A2 X2 port avaliable.

Can you help me?

With best regards from Portugal

You do not since you are not using the lightbridge as the RC link only video downlink.  

Thanks.
One more question.
I know i cant fly with Lightbridge and 2.4 Data Link at the same time, but can i fly with lightbridge (only for video) and control the drone with the graupner mz-24 without having interference troubles? Or i'm putting the drone at risk?

Hi
I have same problem.
- A2 flight system;
- 900 Mhz Datalink;
- Dji Lightbridge;
- Futaba  T14SG transmitter for multicopter control;
-gopro hero3 camera

Problem that I have
How should I connect RC control transmitter to ground system of Lightbridge?
I used RC control transmitter (FUTABA) independed
After I connected to groundsystem of Lightbridge.
But connection is disconnect  T14SG between multicopter.
What should I do?
Regards

Only RC cotroller. there is not gimbal controller

That is not recommended.  I would use a 5.8gHz Tx for RC control.

Hi, guys.

2.4G Ground Station can not work with Lightbridge becauce of interference. But 900M Ground Station can.

Hi
signal of my futaba 14sg is not appearance on Ipad LB display. SIgnal is zero
Why ?
I don't understand
What should I do?

My devices are
A2
GS 900
LB
gopro hero3+ (I have not gimbal)
1 Futaba 14SG ( only for RC control (multicopter) )
Video Led is green on LB air system.
there is not video problem. there  is image.
Futaba connected LB. But signal is red and zero. And Futaba connected A2.
A2 is answering to futaba. But LB display is not answering to futaba. Always signal  is zero.
Regards.

Hi, you must have forgot to connnect the Gimbal Port of LB air unit to CAN1 of A2 :

I have just gone through the same problem with a Graupner MC32 and Lightbridge.

If you use the Graupner radio set through Lightbridge you need to set your TX DSC output port to PPM24 to get 12 channels…. thats it … thats all you can use so the remaining 4 channels on my TX are redundant.

This now turns your Graupner TX into a dumb box with knobs and switches with no signal strength or telemetry.

I didn't like the idea of putting all control through a single box so have sold the Lightbridge and have gone back to a traditional set up using 2 receivers  (1 for flight control and 1 for gimbal control) This makes it easy to swap between single operator and dual operator via binding and unbinding receivers and model change.

I now have full control of my S900 again and am in the process of getting a dedicated HD video transmitter. I have fitted a FPV camera with iOSD and a camera switch so i can still get my on screen display.

if you are connecting Graupner to an A2 have a read of my other thread relating to this,

http://forum.dji.com/forum.php?m ... age%3D1&lang=en

Hope this helps, i went down this path but went back to splitting the control and video due to a lot of issues i was having with reliability.

You need good reliable control of your machine first (which i had with the Graupner) and then think of HD video secondly, you are recording HD locally at the multi rotor anyhow and you should be flying line of sight.

Thanks for your help
Problem is resolved
I have a question.
My devices:
A2
LB
GS900
Futaba 14sg
How can I  go to  far?
Does distance depend GS or LB?
Which is?
LB=2km    GS = >4km
both simultaneously = ?

If you use the Grau ...

It is so stupid that Dji didnt made an option to use the lightbride only for video transmition, making an option to chose the channel to transmit the video without interference for the graupner/futaba original receivers. I dont want to use lightbridge with my graupner tx trainer port, when i have it's own receiver that is excelent and still the best solution to work with.

Please DJI make a solution for this problem.
