5V - Power
GND - Ground
Video - Yellow
Blue - CC  ( ???? )

Hay Everyone..

Just another Stupid Noob Question from yours truly..lol

I have an older 3 wire Analog (TU or TV 1200) Camera that came with one of my Walkera F-210 Quads, And those
Cam's are 3 wire. Pwr, Gnd and Video.

On the F7, The Analog camera Port has a 4 pin connector.

The 4th wire on the F7 is Blue and labeled CC.???

----------------------------------------------------------------------------------------------------------------------------------

* Whats the CC stand for?

* Am I gonna be able to use this camera for a temporary situation? (Almost got the finds for an Air Unit)

* Or should I just wait till I can put in an Air Unit? 



-Thanks



   

Generally you connect Cam to the Video in pad on the FC, then Video out goes to the VTX. But on some VTX you send Cam to the VTX and let it handle the sending to the FC. So the Happymodel VTX (Diamond and Whoop) do it the, IMO, easier way, where the cam output goes to the VTX first. Also other similar VTX that have the two plug system.

So as to your question, my guess is cam is Video in and CC is video out, because the other two are power. But that would also suggest you have an analogue port for the VTX. If you do have a separate connector for the VTX, then ignore CC and wire the cam to cam and power to power.

Ok I learned something new. CC is for the menu pin on the camera, the one you use to get OSD and change camera options, which i've never bothered doing so far. Your camera has no menu pin, so ignore that wire.

Me aswell...
I appreciate your thought process and direction. 
You got me looking & Thinking differently....

Thx

Hi Cole,

I am going to jump in here.

Let me start by saying that I have had an assortment of experiences in
working with analog video from simple video both with and without OSD
to camera switching devices. I have also tried to mix video signals (didn't 
go well) and have used VTX units with a variety of input options. 

Pathfinder is correct, the blue wire is for Camera Control which allows the
camera settings to be changed via the OSD. This only works if the camera 
has that option. Most of my cameras do not have that feature, so if the camera 
doesn't have it, then just ignore it. 

My thoughts on Camera and VTX wiring. 

It all depends on the VTX unit that you have. 

If the VTX only has one set of pads for video input, I wire this to the VTX
output pads on the FC. Yes, the camera connects to the CAM input pads
on the FC. What happens is that the video feed from the camera goes to
the FC where the OSD information is added and then the video signal 
goes from the FC to the VTX where it is transmitted back to the goggles. 
With this type of VTX, you can connect the camera directly to the VTX,
but if you also connect the FC signal to the same pad, it often distorts
the video as the boards are not designed to mix input feeds. You can
connect the camera just to the VTX, but then you don't have OSD info
from the FC. As for trying to mix two video feeds; one from the camera
and one from the FC (OSD), did not go well. Been there, done that,. 
So, now I only connect the camera to the FC when using this type of 
VTX.

On the other hand, some VTX units have a set of pads for Camera input 
as well as FC input. I think that some of these VTX models might be designed 
to mix the camera feed with the OSD feed from the FC (not sure). In this 
scenario, you have options; connect the camera to the FC or directly to the 
VTX. Personally, I would not connect the camera to the FC and directly to
the VTX at the same time. I would pick one way or the other. 

So, take a look at your VTX. Does it have a Camera  input (pads or 
connector) that is separate from the FC connection? If there is only one 
connector or set of input pads on the VTX, then I would suggest connecting 
those to the VTX pads on the FC and the Camera to the Camera pads 
on the FC.
