KNX USB Interface 330

 KNX USB Interface 330

The USB Stick provides a bidirectional connection between a PC or Laptop and the installation bus KNX (TP). The USB connection is galvanically isolated from the KNX bus. The interface is compatible with the ETS (Engineering Tool Software) 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.
