8.2.4.3 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 timer 1 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 timer 1:

 Use the Timer Selector to select timer 1.

 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.

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 );
