I am trying to change the default trigger setting on a Thorlabs brushless DC controller.
I can read the current setting, but I have troubke changing to change the value to a new setting that matches the application.
Is there a place where I can learn more how to assign values to a member of an enumeration.
Thanks
==============
K>> triggerSetting.Trigger2Mode
ans =
TrigOUT_GPO
K>> triggerSetting.Trigger2Mode = 'TrigOUT_InMotion'
Error setting property 'Trigger2Mode' of class 'KCubeTriggerConfigSettings':
Value must be 'Thorlabs.MotionControl.GenericMotorCLI.Settings.KCubeTriggerConfigSettings+TriggerPortMode'.

first steps
asm = NET.addAssembly("<...>");
enTrigPortModes = asm.AssemblyHandle.GetType("<...TriggerPortMode>")
trigPortModeNames = string(enTrigPortModes.GetEnumNames); % get enum values as strings
% loop through the enumerator or convert string to enum object
trigPortMode = System.Enum.Parse(enTrigPortMode,trigPortModeNames(n)); % from name to object to be assigned

Thanks for the suggestion. It seems that the GetType does not work in this case--I am able to read the type using class, but when tried to typecast using the response about type from class(), get this message:
No method 'GetType' with matching signature found for class 'Thorlabs.MotionControl.GenericMotorCLI.Settings.KCubeTriggerConfigSettings'.
===================================
K>> triggerSetting.GetType("Thorlabs.MotionControl.GenericMotorCLI.Settings.KCubeTriggerConfigSettings+TriggerPortMode")
No method 'GetType' with matching signature found for class 'Thorlabs.MotionControl.GenericMotorCLI.Settings.KCubeTriggerConfigSettings'.
K>> device.MotorDeviceSettings.TriggerConfigSettings.GetType("Thorlabs.MotionControl.GenericMotorCLI.Settings.KCubeTriggerConfigSettings+TriggerPortMode")
No method 'GetType' with matching signature found for class 'Thorlabs.MotionControl.GenericMotorCLI.Settings.KCubeTriggerConfigSettings'.
K>> class(device.MotorDeviceSettings.TriggerConfigSettings)
ans =
'Thorlabs.MotionControl.GenericMotorCLI.Settings.KCubeTriggerConfigSettings'

Hi Raha,
To assign a value to a member of an enumeration, you need to use the dot notation. Here's an example of how to set the Trigger2Mode property to TrigOUT_InMotion:
triggerSetting.Trigger2Mode = Thorlabs.MotionControl.GenericMotorCLI.Settings.KCubeTriggerConfigSettings.TriggerPortMode.TrigOUT_InMotion;
Make sure to use the full enumeration path, including the namespace and the enumeration name, to avoid errors.
