You can also use the Basler pylon Viewer application to easily set the parameters.
For more information about the pylon API and the pylon Viewer, see Section 3.1.1 on page 45.
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.
1. Use the Timer Selector to select timer 1.
2. 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 Basler 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 );
You can also use the Basler pylon Viewer application to easily set the parameters.
When you use the Timer Duration Abs parameter to set the duration time, the camera accomplishes
the setting change by automatically changing the Timer Duration Raw parameter to achieve the
value specified by the Timer Duration Abs setting. This leads to a limitation that you must keep in
mind, if you use Timer Duration Abs parameter to set the duration time. That is, you must set the
Timer Duration Abs parameter to a value that is equivalent to a setting you could achieve by using
the Timer Duration Raw and the current Timer Duration Time Base parameters. For example, if the
time base was currently set to 50 µs, you could use the Timer Duration Abs parameter to set the
duration to 50 µs, 100 µs, 150 µs, etc.
If you read the current value of the Timer Duration Abs parameter, the value will indicate the product
of the Timer Duration Raw parameter and the Timer Duration Time Base. In other words, the Timer
Duration Abs parameter will indicate the current duration time setting.
You should also be aware that, if you change the duration time using the raw settings, the Timer
Duration Abs parameter will automatically be updated to reflect the new duration time.
