[Elphel-support] Help on possible faulty FPC cable [SEC=OFFICIAL]

[Elphel Support]

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 ?



Andrey

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.
