(SOLVED) Can't Get Walkera G-2D Gimbal to work with Pixhawk

I really wasn't sure which section to post this in, so if this is the wrong section I'll apologize now and please point me in the right direction.

I've been reading through the every section of every website I can locate trying to find any help to attach and control a Walkera G-2D Brushless Gimbal to the Pixhawk controller.

I can't seem find anything about it. Let me first say that I am new to this so my experience is minimal. This is my first custom drone project.

I am in the process of building a new rig with a Tarot 680 Pro, DJI E600 motor system and the Pixhawk controller. I have a Walkera G-2D Gimbal that I would like to use.

Has anyone already attached this Gimbal to a Pixhawk?
Any wiring diagrams I can use?

The G-2D controller has a power input and three controller pins for Pit / Roll / AUX, but there is no Ground connector on the control pins.

Heres a link to the limited manual showing the wiring and connectors. (http://img.banggood.com/images/upload/2 ... Manual.pdf)

The diagram in the Wiki (http://copter.ardupilot.com/wiki/common-tarot-gimbal/) shows using the AUX 1 port S and GND pins. Im assuming the S pin connects to the pitch pin on the Walkera G-2D controller, but where would I connect the GND pin?

Any help appreciated.

  Hmmm. Not sure.
  
  Have you altered the Servo Limits?
  
  I have mine set to:
  
  Min: 1200
  
  Max: 1780
  
  My controller cable to attached to Channel 9 and the input from the receiver is Channel 8
  
  After this, It seemed to work.
  
  I did manually set the Gimbal angle using the POT on the Gimbal controller with all Signal wires disconnected first so If my controls failed it would still be at a good angle to continue videoing.
  
  Good look.. Brit in NC :) (Brother in Perth)

    Cheers mate.
    
    I set the servo limits to what you have and messed with the V1 and V2 knobs on the gimbal.
    
    All is good now. From straight ahead I have about 75 degrees of movement up and about the same down down using the RS knob on the Taranis.
    
    I'm a happy man!!
    
    Thanks for your help

So I finally got it working. I now have my Walkera G-2D Gimbal connected to my 3DR Pixhawk. I have full manual control over the Gimbal pitch and the Pixhawk should take control when i use mission planner with ROI and Follow Me modes (Still untested).

I've created a write up of what I did here:
