| The KNX data interface is used for connecting a programming or diagnostics device with an USB interface (e.g. a PC) to the KNX.
The USB interface allows linking to a PC for addressing, programming and diagnosis of KNX components with USB1.1 or USB2 interfaces.
Power is supplied entirely from the connected PC via the USB interface. The USB interface is recognised by KNX when the USB cable is plugged in.
The device is programmed with the physical address locally only via the connected PC and therefore does not have a programming button or a programming LED.
The firmware for the USB interface can be updated via a PC and is therefore future-proof for any later standards.
