6.2.4.3 Setting the Timer Duration Time
There are two ways to set the duration time for timer 1:
by setting "raw" values or
by setting an "absolute value".
You can use whichever method you prefer to set the duration time.
Setting the Duration Time with Raw Values
When the duration time for a timer is set using "raw" values, the duration time will be determined by
a combination of two elements:
Timer Duration Raw parameter, and
Timer Duration Time Base. The duration time is the product of these two elements:
Duration Time = (Timer Duration Raw Parameter Value) x (Timer Duration Time Base)
By default, the Timer Duration Time Base is fixed at 1 µs. Typically, the Duration time is adjusted
by setting only the Timer Duration Raw parameter value.
Range of Timer Duration Raw parameter value: 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.
1. Use the Timer Selector to select a timer.
2. Set the value of the Timer Duration Raw parameter.
You can set the Timer Selector and the Timer Delay Raw 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.TimerDurationRaw.SetValue( 100 );
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.
You can set the Timer Duration Time Base 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 parameter value:
Camera.TimerDurationTimebaseAbs.SetValue( 5.0 );
