I need to know how to wire my runcam swift to my vtx. My vtx has a two wire audio input but the runcam swift has a one wire audio output. How do you wire these two. The wiring is confusing between 3 pin and 5 pin. My understanding is that 3 pin is only video and 5 pin is also audio. Please help.
The image of the VTX on the page you linked only shows 1 Audio port, so I’m not sure where you are seeing this second audio connection.
You should only need to make 2 connections between the Runcam and VTX
Cam Video to VTX Video
Cam Audio to VTX Audio
If you can post a link to a photo of what you are talking about that would help.
