Hello Sirs,
I am doing the wiring for my s900. I have the A2 flight controller and iosd Mark II.  

I am following the dji video for wiring.

I have a quiestion about the cable you can see on this video:

Where should the other end connect? Is it on the A2 PMU?

The iOSD MK II needs to be on the Can 1 port.  Mine is attached to the GPS.

I have done my setup after the video I posted a link to. I only have one question about one last wire that I am not 100% sure where to connect.

This wire is shown on this video , from 4 m and 56 sec.
http://youtu.be/2e0k5r_KXzY?t=4m56s

"Connect the iOSD to the CAN port on the GPS".
It does not show where to connect it.

Here is how I have connected the wire:

Is that the right way to do it?

The PMU is already connected through canbus 2, or it should be. The GPS should be on can 1 and not connected to the PMU.

Hi,

The GPS/Compass has a small aluminum box housing for a CAN connector, in the middle of the wire. This is on that connector that the IOSD Mark II shall be connected with a can wire, no matter the plug you use on the IOSD Mark II.
Then, the top end connector of the GPS will connect on the IMU can connector ( same small alu box as on the GPS wire). And only it's top end connector will finally connect to the MCU.

In short :

- PMU and LED on the CAN 2
- IMU, GPS, IOSD, ZEnmuse, Datalink : CAN 1

Hope this helps

Thank you, I think I got it now ..

In the A2 setup program, my setup looks like this:

What does the orange connection between PMU and A2 tell me? Is there something missing?

Hi, the orange connexion, if it is the one shown on the picture, is simply the PMU power output for the MCU,it will power up the MCU and also allow the voltage sensing ( voltage measurement of PMU). This is the connector like a servo connector, make sure to plug it in the right port and in the right direction regarding the polarity .
BEst regards,
Fabien
