C Use Cases
C.2 Timer
There are four general purpose timers available. The following sections show some use cases,
how the timers can be used.
C.2.1 Strobe Signal Output
The timer can be used to generate a pulse with a certain width on the LineOut output together
with every exposure cycle in order to control an external light. The following procedure shows,
how to configure one of the timer for this purposes:
1.
Select one of the four available timers by setting of the TimerSelector to Timer0, Timer1,
Timer2 or Timer3.
2.
Select the timer trigger source. Set TimerTriggerSource to ExposureStart.
3.
Parameter TimerTriggerActivation can be ignored. This configuration is only necessary,
when Line0 input is selected as a trigger source.
4.
Configure the necessary TimerDuration value and the TimerDelay value.
At this stage, the configured timer generates a pulse of a certain width and after a certain
delay every time, when a new exposure cycle starts, which is indicated by the internally
available TimerActive status. This signal must be connected to the camera LineOut output,
which can be done in the DigitalIOControl section:
1.
Set the LineSelector to LineOut0.
2.
Set the LineSource of this output to the corresponding timer acitve signal: Timer0Active,
Timer1Active, Timer2Active or Timer3Active.
3.
Set the polarity of this output accordingly with the parameter LineInverter.
