IDS peak 2.8.0 / uEye+ firmware 3.33

Specifies the internal signal or physical input line to use as the trigger source. The selected trigger must have its TriggerMode set to "On".

Values description

•Counter0Active, Counter1Active: Specifies which CounterActive signal to use as internal source for the trigger. This feature is only supported by uEye+ cameras (GV and U3 models).

•Counter0Start, Counter1Start, Counter0End, Counter1End: Specifies which counter signal to use as internal source for the trigger. This feature is only supported by uEye+ cameras (GV and U3 models).

•Line0 … Line6 (see overview): Specifies which physical line (or pin) to use as external source for the trigger signal.

•PWM0: Specifies that the trigger source will be generated by "PWM0". This feature is only supported by uEye+ cameras (GV and U3 models).

•SignalMultiplier0: Specifies that the trigger source will be generated by "SignalMultiplier0". This feature is only supported by GigE Vision cameras (GV models).

•Software: Specifies that the trigger source will be generated by software using the TriggerSoftware command.

•Timer0Active, Timer1Active: Specifies which TimerActive signal to use as internal source for the trigger. This feature is only supported by uEye+ cameras (GV and U3 models).

•Timer0Start, Timer1Start, Timer0End, Timer1End: Specifies which timer signal to use as internal source for the trigger. This feature is only supported by uEye+ cameras (GV and U3 models).

•UserOutput0, UserOutput1, UserOutput2, UserOutput3: Specifies which user output to use as internal source for the trigger.

Overview of available lines by camera family

This overview describes all available lines. Depending on the camera model used, not all functions may be supported.

•Input: Physical input line that e.g. serves as trigger input (LineMode = "Input" only).

•Output: Physical output line that e.g. serves as flash output (LineMode = "Output" only).

•GPIO: Input or output line that can be used as input or output. To configure the line as input, change LineMode to "Input". To configure the line as output, change LineMode to "Output".

You will find information about the pin assignment and wiring of your camera either in the hardware descriptions of the respective camera family or in the model-specific data sheet.

Code example

C++

// Before accessing TriggerSource, make sure TriggerSelector is set correctly
// Set TriggerSelector to "ExposureStart"
nodeMapRemoteDevice->FindNode<peak::core::nodes::EnumerationNode>("TriggerSelector")->SetCurrentEntry("ExposureStart");
// Determine the current entry of TriggerSource
std::string value = nodeMapRemoteDevice->FindNode<peak::core::nodes::EnumerationNode>("TriggerSource")->CurrentEntry()->SymbolicValue();
// Get a list of all available entries of TriggerSource
auto allEntries = nodeMapRemoteDevice->FindNode<peak::core::nodes::EnumerationNode>("TriggerSource")->Entries();

  if ((entry->AccessStatus()!=peak::core::nodes::NodeAccessStatus::NotAvailable)
          && (entry->AccessStatus()!=peak::core::nodes::NodeAccessStatus::NotImplemented))
  {
      availableEntries.emplace_back(entry);

}
// Set TriggerSource to "Software"
nodeMapRemoteDevice->FindNode<peak::core::nodes::EnumerationNode>("TriggerSource")->SetCurrentEntry("Software");
