I want to try to connect this with viewfinder from old camera, which has 3 important pins "+5 V", "GND", and "video". I will put there on first two pins of viewfinder 5V power supply separate from #16 camera. So what I have to connect with cable from #16 camera? Only "video" from viewfinder, to "video out" pin from #16 cable and leave "GND" pin from #16 cable without connection? Or this GND also has to be connected somewhere?
Hope someone understand my question. If not, tell me - ask me.
1. If you only want video-out, you only have to connect "GND" and "Video".
2 .If, at the same time, you want to power the camera from a USB source you need to connect the "GND" and "+5V" to your external power supply. You'll need two wires from the "GND" connection. One to the monitor and one to your external power supply.
3. If you want to connect the "video-out" to a monitor and your monitor can also output 5V (± 5%) and has a common GND
, then you need to connect all three pins to your monitor. "Video-Out" and "GND" from the camera to the "Video-In" socket on the monitor and "+5V" to the "+5V" pin on your monitor.
4. If you want to connect the "video-out" to a monitor and your monitor can also output 5V (± 5%) but does not have a common GND
, then you need to connect "Video-Out" and "GND" from the camera to "Video-In" socket on the monitor and "+5V" and "GND" to the "+5V" and "GND" pins or plug on your monitor.
To check if you have a common ground for 3 and 4, measure the resistance between the outer part of the video socket on the monitor and the - (negative) pin next to the +5V. If you have zero or maybe 0.1Ω resistance, then you have a common ground and most likely can use the connection method in 3.
This may sound complicated, but without knowing exactly how your monitor is labeled and if you require an external USB power supply or not it's difficult to explain.
To start with, I would just connect the "GND" and "Video-out". If that works, you can take things a step further. Video-out does not require +5V
. You only need to connect the +5V if you require video-out for more than ~30 minutes.
