Norman,



Yes, you will need to change configuration to reduce cable delay. I will send 
you instructions how to do this during preparation of the second camera (so I 
can reproduce and verify each step).

Each port has 8 values for the delay in 1/4 of the clock period, separate for 
vertical (frame) sync, horizontal (line) sync and 12-bit data. There is 
additional fine delay adjustment, but 1/4 of the period should be sufficient.

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.

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.
