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 Delay Time Base
By default, the Timer Delay Time Base is fixed at 1 µs (minimum value), and the timer delay is
normally adjusted by setting the value of the Timer Delay Raw parameter. However, if you require
a delay time that is longer than what you can achieve by changing the value of the Timer Delay Raw
parameter alone, the Timer Delay Time Base Abs parameter can be used to change the delay time
base.
The Timer Delay Time Base Abs parameter value sets the delay 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 delay time base and it is used by all four of the available timers.
You can set the Timer Delay 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.TimerDelayTimebaseAbs.SetValue( 5 );
Setting the Delay with an Absolute Value
You can also set the Timer 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 a timer using an absolute value:
Use the Timer Selector to select a timer.
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 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 );
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.
