Abstract: A service tool accesses a building automation system to configure and confirm design of an installation, monitor and optimize functionality, commission communication protocols, diagnose, analyze and troubleshoot problems, analyze communications between components, adjust and/or reconfigure parameters, monitor, analyze and debug a building automation system, its components, and the like. The service tool provides a man-machine interface to the building automation system and its components by communicating directly and/or indirectly with the system and its components. The interface displays information about the system, its components. The wireless service tool may operate in multiple modes and/or provide multiple functionality.
