KNX RF Data Interface (USB stick)
The device serves as an interface to KNX installations via radio using the KNX RF standard KNX RF1.R (RF = radio frequency). This allows communication between KNX devices and PC tools.
The communication between PC and KNX system is established via radio. For this purpose appropriate KNX RF devices or KNX RF/TP media couplers are required in the KNX system. The connection to the computer (USB 2.0 type A) takes place via a USB port. With the help of the KNX RF USB data interface, the addressing, programming and diagnostics of the KNX devices can be performed by the commissioning software from version ETS5 or higher.
The device electronics are supplied fully via the USB interface of the connected PC. For this reason the KNX RF USB data interface is not ready for operation if the USB stick is not inserted or the PC is not switched on.
The physical address of the interface is solely programmed (ETS) locally via the connected PC. Thus, the KNX RF USB data interface has neither a programming button nor a programming LED.
Only standard Windows HID drivers that are installed or activated automatically when attaching the KNX RF USB data interface to the PC are required for the device to function. The device can first be accessed by the ETS after successful installation.
