USB interface between PC and KNX TP Bus System

The KNX Interface for USB Connectivity

The KNX USB interface UIM‑KNX 42 establishes a bi-directional data connection between PC and KNX bus. The interface device enables addressing of every bus device in the KNX bus system, setting parameters, visualisation, protocolling and diagnosis of bus devices. With the UIM-KNX 42 network configurations become less time-consuming.

The USB connector is galvanically isolated from the KNX bus. Communication between the UIM‑KNX 42 and the devices connected to the bus is handled via the flexible common EMI protocol. This protocol is designed for actual and future applications. Standard software like ETS, EITT (and others) is handled by the FALCON driver.

The UIM‑KNX 42 supports long telegrams and ensures easy software handling also under operating systems that the FALCON driver doesn´t support (e.g. Linux). For specific diagnostic applications like EITT the UIM‑KNX 42 supports the "Raw Frame" operating mode. Due to HID profile support no specific USB driver is required.
