The way to go is install a GenTL compatible software MVImpact for reference would work, then install harvester and use the correct .cti.

I found a kinda working one inside the installation folder of Spinnaker at: /opt/spinnaker/lib/spinnaker-gentl/Spinnaker_GenTL.cti .

Using Harvester in python i was able to setup some of the camera parameters but not all of them.

I then tried installing Teledyne Dalsa GigE-V Linux SDK (following the advice of the vendor), but no .cti found after installation.

Have you been able to find the correct .cti file? Or progress in your acquisition task via python?
