Why the trigger configuration for Hamamatsu camera is not complete?

Hi, I`m just trying to operate Hamamatsu camera (C13440) by hardware triggering. The problem is that when I type 'triggerinfo(vidB)' in command window, it shows that the TriggerCondition and TriggerSource are 'DeviceSpecific' for hardware trigger type as shown on the picture below. But this Hamamatsu camera indeed support many different TriggerCondition and TriggerSource like 'RisingEdge' and 'EdgeTrigger' which I could make use of these on other computers before. I have already installed ImageAcquisition tool box and Hamamatsu camera adaptor, the camera can work fine in GUI. Can anyone help me solve this issue? Thanks a lot.

Hi Shu Guo, what version of Matlab and ImageAcquisition package for Hamamatsu camera adaptor are you using? I am using Matlab2021a and Image Acquisition Toolbox Support Package for Hamamatsu Hardware last version (mar2020) and I can't see any adaptors with "imaqhwinfo" after installing the package. I have the Orca Flash 4.0 V3 C13440 with CameraLink from Hamamatsu. Thanks in advance

Hi,
Trigger sources and the conditions that control hardware triggers are device specific. Ideally the supported configurations should be displayed by using triggerinfo function. I think you can try referring the documentation that came with the device to know about its hardware triggering capabilities.
Also, you can refer this for Hardware Support Package System Requirements. You can try the trouble shooting steps mentioned here.

For the Hamamatsu adaptor, the trigger parameters are controlled outside of the triggerinfo() and triggerconfig() functions. The Hamamatsu adaptor simply exposes the trigger-related properties, like mode, polarity, source, etc. as basic device properties. Use propinfo(obj) to look at all of the properties, and you will see several trigger-related properties that you can explore further using propinfo(obj, 'PropertyName').

Clarification: The desired trigger properties are properties of the selected source, not of the videoinput object itself. Use propinfo(obj.Source).
