Camera does not respond to light.
Check if camera is in Freerunning with serial exposure ctrl . When done, check with the pro-
gram “Convenient Cam“ if you can read back any data from the camera like “Mode“, “type“
of CCD, exposure time settings and so on.
If “Mode Freerunning“ works properly, check the signals of the camera in the desired opera-
tion mode. In these modes check if the Trigger signal is present. Please note that a TTL signal
must be fed to the trigger connector if it does not come from the framegrabber (LVDS type).
The typical signal swing must be about 5 V. 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. Beware of spikes on the signal.
Image is present but distorted.
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
frame grabber can work with the data rate of the camera.
Image of a color version camera looks
strange or false color appear.
If the raw image looks OK, check the camera file to see if the pixels 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.
Colors of a color version are not perfect
– especially when using halogen light.
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.
No serial communication is possible
between the camera and the PC.
Use “load camera DLL” and try again.
