KNX USB Interface 332

The KNX USB Interface 332 Stick provides a bidirectional connection between a PC or Laptop and the installation bus KNX (TP) and now supports KNX Long Frames. Like with its successor, the KNX USB Interface 330 Stick, the USB connection is galvanically isolated from the KNX bus. The interface is compatible with the ETS and with the Falcon driver of the KNX Association. The device is thus supported by many visualization programs. In order to connect own software to KNX via this USB interface our cross-platform SDK kDrive is available.

The KNX USB Interfaces 332 Stick implements a complete KNX Stack with communication objects and BAOS protocol V2. Thus, it offers the possibility to extend devices with USB connection to full KNX devices, which can even be programmed by ETS.
