4.6.4 Trigger Resolution
For a succesfull 3D image acquisition it is important to use the encoder pulses from the
conveyer belt or a similar device for triggering the image acquisition of the camera. However,
it may occur that the delivered encoder pulse frequency exceeds the requirements of the 3D
application. To allow for exact configuration of the image acquisition system the Trigger
Resolution feature allows to skip a predefined number of trigger pulses delivered from the
incremental encoder.

Figure 4.35: Timing in Trigger Resolution mode. Example: Applying a Trigger Resolution value of 2 will
skip two trigger pulses from the incremental encoder and capture images upon every 3rd trigger pulse.
4.7 Strobe Output
The strobe output is an opto-isolated output located on the power supply connector that can
be used to trigger a strobe. The strobe output can be used both in free-running and in trigger
mode. There is a programmable delay available to adjust the strobe pulse to your application.
The strobe output needs a separate power supply. Please see Section 5.1.3 for
more information.
