Issue with Device-Specific Properties with GigE camera

I am using the IMAQ toolbox to get video from a Prosilica GS650 GigE camera. I'm trying to use an external hardware trigger to get a certain number of frames of continuous acquisition. I think I should be able to do this by setting src.TriggerSelector to 'AcquisitionStart' and src.TriggerSource to 'FixedRate,' but this results in an error: 'The enumerated property should have contained the IMAQ value.' I can't find any documentation for this error message and I'd really appreciate any help with what it means and what I can do to get around it. Note: the list of device-specific properties in MATLAB doesn't match the names of those properties given in the manual for my camera, which has contributed to a lot of confusion over which property does what. It's very possible that I'm not using the right properties for what I'm trying to do, but if so I'm not sure how to figure out what the right ones are since the documentation doesn't match up.

Here's the list of properties in MATLAB:

To understand the issue better, try the following steps:

1. Is the 'TriggerType' property set to 'hardware'? 2. Try using 'propinfo' function to know more specific details about the properties that you are trying to set.Refer to the documentation link below: http://www.mathworks.com/help/imaq/use-advanced-property-support-in-the-gige-vision-and-genicam-gentl-interfaces.html#bu80mqi

3. How are you creating the object?(sample code could be helpful). You can also refer to the following documentation link to know the advantages of using gigecam object vs. videoinput object: http://www.mathworks.com/help/releases/R2016a/imaq/gige-vision-acquisition-gigecam-object-vs-videoinput-object-1.html

Hi KCRobot,

Have you tried using gigecam? That should match more closely with the GigE Vision standard.
