Setting the Exposure Overlap Time Max Using Basler Pylon
You can use the Basler pylon API to set the Exposure Overlap Time Max Abs parameter value from
within your application software by using the the Basler pylon API. The following code snippet
illustrates using the API to set the parameter value:
// Set the Exposure Overlap Time Max to 3000 µs
Camera.ExposureOverlapTimeMaxAbs.SetValue( 3000 );
You can also use the Basler pylon Viewer application to easily set the parameters.
Setting the Exposure Overlap Time Max Using Direct Register Access
If you are parameterizing the camera via direct register access, the Exposure Overlap Time Max
Raw register sets the exposure overlap time max.
To set the exposure overlap time max via direct register access:
 Set the value of the Exposure Overlap Time Max Raw register.
A value in a raw register is simply an integer value with no units. To determine what the actual
exposure time will be, you must multiply the value in the raw register by the camera’s time base.
The time base on ace cameras is 1 µs.
For example, if you set the Exposure Overlap Time Max Raw register to 3000, the exposure overlap
time max would be 3000 µs (3000 x 1 µs = 3000 µs).
Selecting the Frame Trigger Wait Signal as the Source Signal for an Output Line
Using Basler Pylon
You can select the frame trigger wait signal as the source signal for the camera’s GPIO line
(assuming it is set as an output) or the CL Spare output line. Selecting a source signal for the output
line is a three step process:
 Configure the GPIO line as an output (if you want to use the GPIO line).
 Use the Line Selector to select the desired line.
 Set the value of the Line Source Parameter to the frame trigger wait signal.
You can set the Line Selector and the Line Source 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:
// Configure the GPIO line as an output
Camera.LineSelector.SetValue( LineSelector_Line1 );
Camera.LineMode.SetValue( LineMode_Output );
//Select the GPIO line
Camera.LineSelector.SetValue( LineSelector_Line1 );
