USB, Firmware Update and Windows-Installation
The USB-interface has the following properties:
USB current consumption 10mA max.
full speed USB device (12MBit/s max.)
The DALI-USB rmware will be updated automatically via USB by the DALIBusServer.exe.
This program is part of the„DALI-Cockpit“-software-package. The DALI USB is implemented
as USB HID (Human Interface Device).
A driver installation is not necessary due to the windows-integrated built-in support for human inter-
face devices. The DALI USB will be detected by the operating system and all required drivers will be
installed automatically. After the installation process is nished successfully you can nd the entry
under the node HID (Human Interface Devices) in the device manager.
