Ok, I've changed to CCD for the two cameras.
I've connected my EAF and my ASI224MC to the ASI1600MC and this camera to the RPi..
But I' don't see my EAF...
So, tomorrow, I'll connect only my EAF like you said.
How is it possible to check if my EAF is correctly connected or if my EAF isn't dead ?
Thank you.
