GVS KNX Line Coupler, 2SU MDRC, used as line coupler, backbone coupler or line repeater, filter table for line-crossing telegrams

The coupler can be used as line coupler, backbone coupler or repeater as well in existing KNX networks as in new KNX networks. It has a filter table with the help of which bus telegrams are either blocked off from one of the two lines or are passed on to another line thus reducing the bus load. The filter table is created by the ETS (KNX Tool Software) automatically on commissioning the system.
