2.9.4 Selecting a Source Signal for the Output Line
To make the physical output line useful, you must select a source signal for the output line.
The camera has the following standard output signals available that can be selected as the source
signal for the output line:
 The Timer 1 signal.
Currently, the Timer 1 signal is always selected as the source signal for the camera’s output
line and this can not be changed.
The timer 1 signal works as follows:
 The timer starts when exposure for a frame begins.
 A delay period begins to expire.
 When the delay expires, the timer signal goes high and a duration period begins to expire.
 When the duration period expires, the timer signal goes low.

Setting the Timer 1 Parameters Using Basler Pylon
When Basler pylon is used, setting Timer 1 is a three step process:
 Use the Timer Selector parameter to select Timer 1.
 Set the value of the Timer Delay Abs parameter.
 Set the value of the Timer Duration Abs parameter.
The Timer Delay Abs parameter sets the timer delay in microseconds, and the Timer Duration Abs
parameter sets the timer duration in microseconds. The delay and the duration should be set in
increments of 1 microsecond.
You can use the pylon API to set the Timer Selector, the Timer Delay Abs, and the Timer Duration
Abs parameters from within your application software. The following code snippet illustrates using
the API to set the parameters:
Camera.TimerSelector.SetValue( TimerSelector_Timer1 );
Camera.TimerDelayAbs.SetValue( 100 );
Camera.TimerDurationAbs.SetValue( 200 );
You can also use the Basler pylon Viewer application to easily set the parameters.
For more information about the pylon API and the pylon Viewer, see Section 4 on page 45.
