Trigger Mode#

The Trigger Mode camera feature allows you to enable or disable triggered image acquisition for the trigger type selected.

Using the Feature#

Setting the Trigger Mode#

To set the trigger mode:

Set the TriggerSelector parameter to the desired trigger type, e.g., FrameStart.
Set the TriggerMode parameter to one of the following values:
- On: Enables triggered image acquisition for the trigger type selected.
- Off: Disables triggered image acquisition for the trigger type selected. Trigger signals are generated automatically by the camera.

By default, the trigger mode is set to Off for all trigger types. This means that free run image acquisition is enabled.

Immediate Trigger Mode#

On some camera models, the Immediate Trigger Mode is available.

When the Immediate Trigger Mode is enabled, exposure starts immediately after triggering, but changes to image parameters become effective with a short delay, i.e., after one or more images have been acquired. This is useful if you want to minimize the exposure start delay, i.e., if you want to start image acquisition as soon as possible, and if your imaging conditions are stable.

To enable the Immediate Trigger Mode, set the BslImmediateTriggerMode parameter to On.

The setting takes effect whenever the TriggerMode parameter is set to On.

// Select the Frame Start trigger
camera.TriggerSelector.SetValue(TriggerSelector_FrameStart);
// Enable triggered image acquisition for the Frame Start trigger
camera.TriggerMode.SetValue(TriggerMode_On);

INodeMap& nodemap = camera.GetNodeMap();
// Select the Frame Start trigger

camera.Parameters[PLCamera.TriggerMode].SetValue(PLCamera.TriggerMode.On);

/* Macro to check for errors */
#define CHECK(errc) if (GENAPI_E_OK != errc) printErrorAndExit(errc)
GENAPIC_RESULT errRes = GENAPI_E_OK;  /* Return value of pylon methods */
/* Select the Frame Start trigger */

You can also use the pylon Viewer to easily set the parameters.
