8.2.4.1 Setting the Trigger Source for a Timer
To set the trigger source for a timer:
Use the Timer Selector to select timer 1 or timer 2.
Set the value of the Timer Trigger Source parameter to exposure active. This will set the
selected timer to use the start of exposure to begin the timer.
You can set the Trigger Selector and the Timer Trigger Source parameter value from within your
application software by using the pylon API. The following code snippet illustrates using the API to
set the selector and the parameter value:
Camera.TimerSelector.SetValue( TimerSelector_Timer1 );
Camera.TimerTriggerSource.SetValue( TimerTriggerSource_ExposureStart );
For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide
and API Reference.
You can also use the Basler pylon Viewer application to easily set the parameters.
For more information about the pylon Viewer, see Section 3.1 on page 43.
8.2.4.2 Setting a Timer Delay Time
There are two ways to set the delay time for a timer: by setting "raw" values or by setting an
"absolute value". You can use whichever method you prefer to set the delay time.
Setting the Delay with Raw Values
When the delay time for a timer is set using "raw" values, the delay time will be determined by a
combination of two elements. The first element is the value of the Timer Delay Raw parameter, and
the second element is the Timer Delay Time Base. The delay time is the product of these two
elements:
Delay Time = (Timer Delay Raw Parameter Value) x (Timer Delay Time Base)
By default, the Timer Delay Time Base is fixed at 1 µs. Typically, the delay time is adjusted by setting
the Timer Delay Raw parameter value.
The Timer Delay Raw parameter value can range from 0 to 4095. So if the value is set to 100, for
example, the timer delay will be 100 x 1 µs or 100 µs.
To set the delay for a timer:
Use the Timer Selector to select a timer.
Set the value of the Timer Delay Raw parameter.
You can set the Timer Selector and the Timer Delay Raw parameter value from within your
application software by using the pylon API. The following code snippet illustrates using the API to
set the selector and the parameter value:
Camera.TimerSelector.SetValue( TimerSelector_Timer1 );
Camera.TimerDelayRaw.SetValue( 100 );
