The Timer Duration Raw parameter value can range from 1 to 4095. So if the value is set to 100,
for example, the timer duration will be 100 x 1 µs or 100 µs.
To set the duration for a timer:
Use the Timer Selector to select a timer.
Set the value of the Timer Duration Raw parameter.
You can set the Timer Selector and the Timer Duration 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.TimerDurationRaw.SetValue( 100 );
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.
Changing the Duration Time Base
By default, the Timer Duration Time Base is fixed at 1 µs, and the timer duration is normally adjusted
by setting the value of the Timer Duration Raw parameter. However, if you require a duration time
that is longer than what you can achieve by changing the value of the Timer Duration Raw
parameter alone, the Timer Duration Time Base Abs parameter can be used to change the duration
time base.
The Timer Duration Time Base Abs parameter value sets the duration time base in µs. The default
is 1 µs and it can be changed in 1 µs increments.
Note that there is only one timer duration time base and it is used by all four of the available timers.
You can set the Timer Duration Time Base Abs parameter value from within your application
software by using the pylon API. The following code snippet illustrates using the API to set the
parameter value:
Camera.TimerDurationTimebaseAbs.SetValue( 5 );
Setting the Duration with an Absolute Value
You can also set the Timer duration by using an "absolute" value. This is accomplished by setting
the Timer Duration Abs parameter. The units for setting this parameter are µs and the value can be
set in increments of 1 µs.
To set the duration for a timer using an absolute value:
Use the Timer Selector to select a timer.
Set the value of the Timer Duration Abs parameter.
You can set the Timer Selector and the Timer Duration Abs 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.TimerDurationAbs.SetValue( 100 );
