KNX USB Stick 332 is a data interface between a PC or laptop and the KNX installation bus. It can be used as a programming interface for ETS® software version 3 (or higher) and supports KNX long telegrams. Long telegrams allow faster downloading to devices capable of receiving them.

The device's LEDs indicate the operating status and communication errors on the bus. The USB connector is galvanically isolated from the KNX bus.

Notes for developers

KNX USB communication is based on HID and cEMI telegram encoding according to KNX specifications. Weinzierl's kDrive cross-platform SDK is available to integrate the KNX USB interface into applications running on Windows or Linux.

In addition to the telegram interface via cEMI, the KNX USB Interface Stick 332 includes a complete KNX stack with communication objects and the BAOS V2 protocol. This allows the device to extend devices with USB connection to full KNX devices, which can also be programmed by ETS.
