The desktop app makes Check Update requests to the server and receives a response that indicates whether an update is available.

Windows: The response that is about 564 bytes.

Mac: The response is about 676 bytes.

If the response indicates that there is an update pending, a Get Update (GU) call follows. For example, when an operator changes the desktop app settings in the management system, the desktop app receives a response at the next check update that indicates a get update is needed.

The desktop app then makes a GU request after the Check Update, and receives the settings as XML in the response.
