Setting the Delay Time with an Absolute Value
You can also set the timer 1 delay by using an "absolute" value. This is accomplished by setting the
Timer Delay Abs parameter. The units for setting this parameter are µs and the value can be set in
increments of 1 µs.
To set the delay for timer 1 using an absolute value:
 Use the Timer Selector to select timer 1.
 Set the value of the Timer Delay Abs parameter.
You can set the Timer Selector and the Timer Delay 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.TimerDelayAbs.SetValue( 100.00 );
You can also use the Basler pylon Viewer application to easily set the parameters.
When you use the Timer Delay Abs parameter to set the delay time, the camera accomplishes the
setting change by automatically changing the Timer Delay Raw parameter to achieve the value
specified by the Timer Delay Abs setting. This leads to a limitation that you must keep in mind, if
you use Timer Delay Abs parameter, to set the delay time. That is, you must set the Timer Delay
Abs parameter to a value that is equivalent to a setting you could achieve by using the Timer Delay
Raw and the current Timer Delay Base parameters. For example, if the time base was currently set
to 50 µs, you could use the Timer Delay Abs parameter to set the delay to 50 µs, 100 µs, 150 µs, etc.
Note that, if you set the Timer Delay Abs parameter to a value that you could not achieve by using
the Timer Delay Raw and current Timer Delay Time Base parameters, the camera will automatically
change the setting for the Timer Delay Abs parameter to the nearest achieveable value.
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.
