KNX USB Interface 330 (Module)

The interface is used to establish a bi-directional data link between a PC and the KNX-Bus. The module can be integrated into an existing system, such as an industrial PC. The USB connection is galvanically isolated from the KNX-Bus. The circuit is compatible with KNX medium TP, the firmware supports protocol EMI1.

The interface is compatible with the ETS software ETS3. For installation of the interface in programs for Windows or Linux a free SDK named kDriveExpress is available.
