This note is saying, before the HWC will launch it must be configured with connection settings to the server, e.g. server name, port, etc..
The application can obtain these settings a couple of ways:
1) The user manually enters them in via the Settings Screen (this is the default implementation)
2) You can customize the HWC to provide some or all of these settings so the user does not need to manually enter in the info. Sounds like this is what you want to do? If so, please take a look at:
Configuring Default Values for the Settings Screen
Thanks,
