Note : if you're simply connecting it to a camera without going through the FC - whether or not you want OSD - don't use the yellow lead connected to the "camera plug" (see second manual diagram) as the video input to the VTX. You won't get a picture. Instead connect the signal from the camera to the yellow lead labelled "FC Vout". That's because the unit is very much designed for a Betaflight-enabled FC.
Thanks to John Brindle for this nugget of info, great for car based FPV.
