Trouble with my FPV camera
Posted: Sat Jun 18, 2016 11:28 am
This is just odd. Before I built my ZMR250, I had a mini FPV camera on my Skyfun. I tested the video system and everything worked. I have two other identical cameras. One was on my other FPV plane (still haven't flown, lol) and I bought the second one because the mini's were "out of stock". When the new camera arrived, I found that it just wasn't gonna fit on the ZMR250. So, I pulled the mini camera off the Skyfun and put it on the ZMR250. The video system on the ZMR works just fine. Now, I've taken the new camera and put it on the Skyfun but I get no picture when the video system is powered up. I took the other camera off my other plane and hooked it up to the Skyfun....still no picture. I take the mini from the ZMR and hook it up to the Skyfun and the video system works.
Now, when I last tested the non-mini camera on my other FPV ship, it worked with no problem.
I've gotten my volt meter out and I have 12ish volts going from the battery to the ImmersionRC vtx. Then I have 5v leaving the vtx to the connector that goes to the FPV camera. So, all the wires seem to be ok but I have no picture. And what's even more odd, when I try using the other non-mini camera....same problem. The power is there, just no picture.
Is there a way to check the signal wire with my volt meter? It's just odd that my mini FPV camera works on my ZMR and my Skyfun but the two non-mini FPV cam's don't work on my Skyfun.
Any thoughts?
