  • WIRELESS BUILDING AUTOMATION AND CONTROL NETWORK
    Publication number: 20090150004
    Abstract: A network (20) employs a wireless network topology (30), a wireless network manager (40). Network (20) further employs a wireless device (70) and wireless device manager (80) pairing and/or a wireless system (90) and a wireless system manager (100) pairing. Managers (40, 80) cooperatively control an operating profile and monitor an operational status of the device (70). Managers (40, 100) cooperatively control an operating profile and monitor an operational status of system (90). Manager (40) can be installed on a computer (150, 170) and wirelessly communicate within network (20) via a wireless control device (160, 180) employing a port connector (161, 181) that can be plugged into a port (151, 171) of the computer (150, 170). Device (70) or system (90) can implement a digital ballast (120) that determines an average power consumption of the digital ballast (120) drawn by a power interface (121) of digital ballast (120).
