Hi, Andrey, Our electrical technician has decided to use shorter FPC cables for the two sensors. And it will be one sensor per camera body. One with 100mm FPC and another with 70mm FPC. My question is when we replace the 450mm with 100mm cable, do we need to change the port configuration?
Thanks.
Regards,
Norman

After you remove the fan from the bottom of the camera (two M2.5 screws) you
need to remove 8 (4+4) screws from the front and back panel. Then remove front
one and push boards with the heat plate (boards are attached to it) pushing on
the heat plate (you may make some simple tool to push on that plate). When
pushing - be careful with the SSD not to hit the camera tripod mount part as it
becomes loos when you remove the fan.
When you will be reassembling the camera - I put the back panel on the
assembled boards first, and then slide them together into the camera body,
making sure that a micro-USB connector does not hit the back panel (otherwise
it can be easily peeled off the PCB).
And yes - camera does not see port 1. It is more likely the PCB, not the cable
problem - I do not see how the cable can fail gradually:

Norman,
If it is not too late - you need to take off fan first, then slide out the
boards of the camera. Fan has a long connector reaching to the board through
the hole.

Hi, Andrey,
Thanks for the quick response.
Here are the two log files, with both ports connected with sensors. I'll try to
open up the box to reconnect the cable shortly.
Regards,
Norman

Hello Norman,
Can you get log files from the camera?
>From Linux system
ssh-copy-id root@192.168.0.9 # Or whatever IP is assigned to the camera
default password is pass
Then you can use scp to copy files to your local directory:
scp root@192.168.0.9:/var/log/messages
scp root@192.168.0.9:/var/log/autocampars.log
Abd then send these files.
Yes, we will prepare the new camera, but in any case I would like to try to
troubleshoot the camera you have, if that will not work we will send you a
replacement one. You may try to open the camera and get access to the camera
side of the cable. Camera has 4 cable ports so you may try to either just
reconnect the cable or try other port.
The gold-plated pins on the cable end should be towards the connector lock.
When you try different port, the image can be corrupted (delays fro the long
cable were set only for ports 0 and 1.

Hi, Andrey,
I am not able to get port 1 back. When I connected both ports, I got only one
sensor image on port 0. And if I connect only port 1, the system can't find any
sensor.
Anyway, we decided to buy another 393 system to support the second sensor. This
is mainly because we need to put the two sensors far away from each other,
where the FPC cables are not long enough to connect both sensors to the same
system.
Enclosed is our previous order invoice. We want to duplicate the NC393 system,
but no sensor or lens is rquired. We need one 450mm FPC cable pre-cofigured for
the system, and a PoE power supply. Can you please ask your sales team to
provide me with a new quote? Thank you.

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.
