Hello!
So I will be using a Tarot Liti gimbal and a TS832 video transmitter for a project. I'm having trouble getting the video from the camera to be transmitted, and I'm pretty sure it's a matter of wiring because the VTX has 3 wires to plug in the camera, while the Tarot has a 2 wire video output, and the camera has to be plugged to the gimbal, so that the video goes out of the video output on the top terminal of the gimbal. Here are the details:

Here are the details:
- VTX has 2 wires for its own power input and 3 wires for camera, in the manual they are marked as: video in, cam gnd -, cam v out + (yellow, black, red respectively - AFAIK the black and red are just camera power, while the black and yellow are for the video signal - and +)
- Camera is connected to the gimbal with a very short cable to a 4 pin socket near the pitch motor (it's tidy and I'd like to keep it that way - I could plug the camera directly to VTX but I'd very much rather not). The camera powers on when I turn on the gimbal.
- The gimbal has a video output on its top terminal, marked VGND and VIDEO (black and white)
- camera power input requires 5V. This Tarot is designed for this camera, and the camera turns on, so I assume that the Tarot is giving the camera proper voltage.
- battery -> voltage filter/stabilizer -> VTX
battery -> Tarot gimbal power in
Tarot VIDEO (white) -> VTX Video IN (yellow)
I assumed this would work because the camera has power from the gimbal, and VTX and gimbal have a common ground, so one wire could suffice? (I'm not very good at this). Anyway, it did not work - battery -> voltage filter/stabilizer -> VTX
battery -> Tarot gimbal power in
Tarot VIDEO (white) -> VTX Video IN (yellow)
Tarot VGND (black) -> VTX CAM GND -
I thought this would work, but it didn't. - This is a setup that worked, but required a direct cable form camera to VTX:
battery -> voltage filter/stabilizer -> VTX power input
battery -> UBEC (step down to 5V) -> gimbal power in (different gimbal, not tarot)
VTX CAM GND and VTX CAM V OUT -> input of UBEC (step down to 5V) -> camera power input
VTX VIDEO IN -> camera video out +
