Issue
When upgrading a Vista from Vista 5.1.3 to Vista 5.1.4, make changes in the Lon network and download it the Xenta master goes offline. This only when running the 911 in low bandwidth.
Environment
Vista 5.1.4
Cause
In the Xenta 911 software version 5.1.4 changes are implemented to support extended characters. This means that when using Xenta 911 in low bandwidth, we need to download the node information to the Xenta 911 using a .cfg file instead of a .xml file. If you have a Xenta 911 with version 5.1.4 it waits for a .cfg file and if you do not have TAC Vista version 5.1.4, it cannot deliver a .cfg file.
This means that customers that have upgraded to Vista 5.1.4 need to upgrade all of their Xenta 911s to 5.1.4 if any changes are done in the network.
Resolution
Upgrade the Xenta 911 to version 5.1.4.
Update: This is solved in 5.1.5 and later versions.
