As a result of one of my devices failing and needing to install a replacement device I had to update the ETS catalog to the version of the new device. In this example I needed to update the catalog so that I had access to a Z41 Lite version 3.6. As can be seen in the following image. The catalog currently had only 2 version 3s (being 3.4 and 3.5). Note: I'm not sure but I believe there are several other ways besides what's described here which may have also added the Z41 Lite version 3.6 to the catalog. One way may have been to import the individual device
By selecting the existing Z41 version 3.5 and by right clicking the option to "Update from Online Catalog" appears.
After selecting "Update from Online Catalog" the following pop up appeared.
The following then appears to which I selected "Update Now".
After the update completed and ETS was restarted the newer version has been added to the Catalog as per the following.
