3.2 Configuring the interface

If the “New” button is pressed in the “Communication” view, the dialog window “New
connection” opens. It is possible to choose between the following connection options:
USB Communication via USB
RS.232 Standard Serial standard connection
RS.232 FT1.2 Serial BCU2 connection
IP (EIBlib/IP) Communication via iETS
KNXnet/IP IP communication (tunnelling)
KNXnet/IP Routing IP communication (routing)

If communication should be ensured via an RS232 connection, the COM-PORT on which
the connecting cable from the commissioning PC to the RS232 is located must be
selected under the communication parameters (normally COM 1).
When using a USB interface, the required KNX USB driver is installed directly the first
time a connection is made to the PC.

Note: This occurs for each USB port i.e. if the USB cable is inserted in another USB port
of the PC, the driver is installed again. Possibly, the connection pop-up menu must be
opened once more, to ensure that communication functions again.
