Hello Norman,
I'm sorry you are having these problems. 450mm cables are close to the maximal
usable length. Most likely the problem is related to the need to change delay
in the sensor interface signals relative to clock, not the hardware problem
with the cable. But it still can be the problem, of course.
What happens now - you can get a picture from port 0, and nothing at all on
port 1? Black image, corrupted image, getting stuck trying to get an image?
What happened before (when it was restoring after reboot)?
If you are getting corrupted image - can you please send it ?

Dear Elphel support team,
We have a NC393 system, with two sensors connected by 450mm FPC cables. Ever
since
we put the system together in last July, port 1 was unstable and lost
connection every a few
weeks. Rebooting the system would get the port back. However, recently that
port was
totally lost. We can’t have it back by rebooting or reconnecting the camera to
the cable.
We did a simple debugging by swapping sensors between the two FPC cables. Both
sensors
worked with port 0, and neither of them worked with port 1. So we presume the
FPC cable
on port 1 is faulty. We didn’t open up the box to check the connection between
the cable and
the board. I am looking for advice on what I should do next. Shall I open up
the box to check
the internal connection or shall I simply order another FPC cable from you? And
Is the cable
fragile?
Thanks.
Regards,
