Google Connector Install and Configuration
Open your web browser and go to https://www.rwcloudconnector.com
Enter the user name and password for your g-mail corporate account. Make sure that you're log in with the account you wish your RoomWizard’s to use. This account will need to have complete access to every room's calendar. We recommend you use an administrator or non-user account for this purpose, so that normal calendar use doesn't interfere with the RoomWizard.
Once logged in you get the following screen.

Choose "Make changes to events", then click "Add Person".
Finally, save the calendar.
