The KNX USB Stick 332 serves as a data interface between a PC or laptop and the
KNX installation bus. It can be used as a programming interface for the ETS® software version 3 (or higher) and
supports KNX Long Frames. Long telegrams enable faster downloading to devices that
can receive these telegrams. The LEDs in the device indicate the operating status and communication errors on the bus. The USB connection is galvanically isolated from the KNX bus.
