Status: offline 		I have trouble connecting my 5V BWAV transmitter to my 12V camera, the camera has 4 connections and the tx only 3
In the test setup I use (temporary) separate batteries, but I'm getting confused with the 2nd ground wire from the camera
I tried to leave #4 disconnected but as expected it didn't work

Camera connections:

1)red +12V
2)black -12V
3)white video
4)black video ground (?? goes to where ??)

tx has only 3 wires;

red + 5V
black - 5V
yellow - video

Thanks in advance.
GJ

Status: offline 		The video and power grounds can and should be tied together at the power source (or as near as possible to it). You can connect them together right at the transmitter if you like, but you will probably get a little less noise on the video signal if you connect the grounds closer to the batteries. All of the grounds need to be tied together (5v (-), 12v (-) and video (-).

Status: offline 		It's so simple when you know it.. .. Thanks a lot !, It works now.

On the subject of wiring, what is generally used for the cam on the models when the camera is far from battery/tx, let's say on the tail?. [heavy] shielded cable?

I planned to use [twisted] servo lead, would that add noise to video or is it ok ?

In that case I can mount the camera on the tail for example, and keep the rest in front of the CG.....

I use micro co-axial cable when I run more than a few inches. Twisted pair might be OK as well, but will be more prone to picking up electrical noise. I have run with my camera on the tail of my little delta wing and in the nose of my larger plane. I end up putting the TX and converter in a place that counter balances the camera to keep the CG where it needs to be.
