Appendix A – Troubleshooting
Problem:
Camera does not respond to light
Solution:
Please execute following steps
Check if camera is in mode 0).Thus: Free running with serial exposure ctrl. When
done, check with “Convenient Cam “program if you can read back any data from the
camera like : Mode, type of CCD, exposure time settings and so on.
If Mode 0) works check the signals of the camera in the desired operation mode like
1) or 2). In these modes check if the Exsync signal is present. Please note that a
differential signal must be fed to the connector. The typical signal swing for LVDS
must be about 250 mV. Below such level the drivers in the camera will not work. If
you use a TTL level signal fed to the TB 5 connector check the quality and swing. If
these signals are not there or don’t have the right quality the camera can not read
out any frame (mode 1 and 2).
Problem:
lmage is present but distorted:
Solution:
Check the camera configuration file of your framegrabber. Check number of “front-
and back porch pixel”. Wrong numbers in configuration file can cause sync
problems. Check if your framegrabber can work with the data rate of the camera.
Problem:
The image of a color version camera looks ”ugly” or false colors appear.
Solution:
If the raw image looks OK check the camera file to see if the pixel need to be
shifted by either one pixel or one line. The image depends on the algorithm used. If
the algorithm is starting with the wrong pixel such effects appear.
Problem:
The colors of a color version are not perfect especially when using a halogen light.
Solution:
Halogen light contains strong portions of IR radiation. Use cut off filters at around
730 nm like Schott KG 3 to prevent IR radiation reaching the CCD.
Problem:
No serial communication is possible between the camera and the PC (CameraLink)
Solution:
Check if your Microsoft ® Dot Net Framework 2.0 installation was successful. Than:
Use “load camera DLL” and try again.
