Connecting and testing the pi cam with Portsdown 4

I have connected my Picam using the ribbon cable provided.
I have the silver pads on the ribbon cable towards the HDMI socket and towards the camera front
I have set Source in M1 to Pi Cam and Output to Pluto
I had expected to see the camera image when pressing TX.
Are there any other settings needed.
I see no led on camera lit and on pressing tx blank screen.
Thanks
Nigel

Hi Nigel
The light on the camera never comes on in Portsdown.
First check on Menu 2 "Pi Cam Monitor" to see if the image appears. Once that is working, then try transmitting.
Unless you have set audio to off (on menu 1) you need to have a white sound dongle connected as well.

Hi Dave, I have tested Pi Cam Monitor. The screen is blank. I have set audio to off for now.

Hi Nigel,
I only had a Picam 3 work, the Picam 4 didn't work for me. Not supported by “Buster”.

Thanks Rene for your reply.
My Pi camera number 3 on pcb and I am not using Buster.
Last night at club we tried many things. We tried with putty to control pi cam. We know the Pi can see the camera is connected. We tried to control Pi cam from ommand line, thiya failed. We tried a USB camera. Same result a solid green screen but Pi knows camera is present.
On the web we found a forum saying delete a file to stop green screen Something relating to successful eprom update. This file deletion made no difference. We updated Portsdown software to latest version this did not fix camera problem.
One progress to report. We did TX test card F and receive it on another receiver.

I am not sure that the Raspberry Pi Camera 3 is compatible with the Buster OS used by the Portsdown. Perhaps someone else who has one could test it.
Oh, and before you ask, the newer operating systems (Bullseye and Bookworm) do not include the modules required for DATV transmission from the camera.
What webcam did you use? Again, that has to be compatible.

Hi Dave
Thanks for your reply
The web cam was just an HP USB web cam that was at our radio club. It will be useful to learn what others are using so I can purchase a known working camera for Portsdown 4
Thanks

Hi Nigel,
For my system based on a RPi 4B I used the Raspberry Pi camera V2, which I bought from CPC:

But is available in lots of places.

Even the eBay £5 knockoffs work reasonably well although a genuine one does better colours and handles lighting better....
