Hi im installing a new DYS VTX on my Tyrant S. I just hooked up the 3 coords (1. 5v in 2. GND 3. AV in) to the cables coming from the FC. This is the same way that both the tyrant s original VTX and a TBS unify were plugged in and worked. When I turned on power after plugging up this DYS, I got no power to it. The rest of the quad had power just fine. This DYS MI200 also has a 5v out and GND with it that I was told you could send to the camera if you wanted. I did not hook these up as the camera already gets power from the FC. Any thoughts? p.s. What does VCC stand for on a FC?
