You should also be aware that if you change the delay time using the raw settings, the Timer Delay
Abs parameter will automatically be updated to reflect the new delay time.
8.2.4.3 Setting a Timer Duration Time
There are two ways to set the duration time for a timer: 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 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. The first element is the value of the Timer Duration Raw parameter,
and the second element is the 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.
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.
