The KSI-01 U is an USB interface providing galvanic isolated bidirectional access to the KNX bus line. It makes network configurations less effort and time-consuming.The KSI-01 U is used to access all bus connected devices in the KNX bus system including commissioning, addressing, setting parameters, diagnostic functions, visualization, protocol....etc.

The connection between the KNX data bus and a PC with standard software like ETS, EITT (also Raw Frame operating mode) and other software is handled by the FALCON driver. The KSI-01U supports long messages (up to 220 byte APDU length) and ensures easy handling in software under operating systems not supported by the FALCON driver (e.g. Linux). The communication protocol used for communication between interface and host is the flexible “cEMl” protocol.
