A/B Trigger Divider
if
ABTriggerDivider
>1 then not all internally generated triggers are applied to the camera logic.
E.g. If ABTriggerDivider=2, then every second trigger is applied to the camera (see Fig. 5.13).

Figure 5.13: A/B Trigger Divider, example with ABTriggerDivider=1, ABMode=quad
A Only Trigger
The camera supports the use of simple incremental decoders that only provide one input, by
enabling the property
ABTriggerAOnly
. The B-signal is ignored in this mode and information
about direction of the object movement is not available: if
ABTriggerAOnly
is enabled then the
encoder position is always incremented. Detailed diagrams are shown in Fig. 5.14 and Fig.
5.15. Note that the quad mode is not available when
ABTriggerAOnly
=true.

Encoder Position
The internal ABTrigger signal before the ABTriggerDivider is processed for the Encoder
Position: every TriggerFwd pulse increments the Encoder Position and every TriggerBkwd pulse
decrements its value. For details refer to the diagram of the corresponding mode.
The Encoder Position value can be accessed through the
EncoderPosition
property or through
the status info that is inserted into the image (see Section 5.7).
