OK, this is the basic situation at start. Now, you recommend to test in single frame mode
"The frame rate can be reduced by going to the external (from the sensor point of view) trigger mode and acquire single frames."

I did that by setting the TRIG_PERIOD to 1, but how do I retrieve the image ? When I just change TRIG_PERIOD in
the parameter editor, Firefox is always waiting for a page that does not arrive, and when I do it by 
  http://192.168.0.9:8081/trig/pointers 
as mentioned in http://wiki.elphel.com/index.php?title=Trigger#Single_frame_triggering_from_PC
There is a reply (with changing values at each try) but I do not know how to check the image. I guess it is
in the circular buffer.

I still have to do that but I'm not at work now. 

A last point : the actual length of the new cable is 30 cm not 20 as I wrote. I guess it's not helping …
