Acquisition Control AW00118501000

For more information about using a hardware trigger to control line acquisition start, see

Section 6.1.5 on page 52.

Exposure Time Control with Trigger Mode = On

When the line start trigger mode is set to on, the exposure time for each line acquisition is

determined by the value of the camera’s exposure time parameters.

For more information about setting exposure time, see Section 6.1.3 on page 46.

6.1.3 Setting the Trigger Mode and Related

Parameters

Setting the Parameters Using Basler pylon

You can set the Trigger Mode and related parameter values from within your application software

by using the pylon API. If your settings make it necessary, you can also set the Trigger Source

parameter.

The following code snippet illustrates using the API to set the Trigger Mode parameter for the line

start trigger to on and the Trigger Source parameter to CC1:

// Select the line start trigger

Camera.TriggerSelector.SetValue( TriggerSelector_LineStart );

// Set the mode for the selected trigger

Camera.TriggerMode.SetValue( TriggerMode_On );

// Set the source for the selected trigger

Camera.TriggerSource.SetValue ( TriggerSource_CC1 );

The following code snippet illustrates using the API to set the Trigger Mode parameter for the line

start trigger to off and the Acquisition Line Rate Abs parameter to 60:

// Select the line start trigger

Camera.TriggerSelector.SetValue( TriggerSelector_LineStart );

// Set the mode for the selected trigger

Camera.TriggerMode.SetValue( TriggerMode_Off );

// Set the exposure time in (µs)

Camera.ExposureTimeAbs.SetValue( 300 );

// Enable the acquisition line rate parameter and set the line rate. (Enabling

// the acquisition line rate parameter allows the camera to control the line

In all cases, the exposure time for each line must be within the minimum and the

maximum stated in Table 7 on page 53. This is true regardless of the method used

to control exposure.
