N 140/13 - Line/backbone coupler

• The line-/ backbone coupler provides a data connection between two separate KNX bus lines and isolates the bus lines from each other to enable the independent local operation of a bus line.
• The device can be used as line coupler, backbone coupler or repeater as well in existing 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 automatically on commissioning the system
• As there are no differences in hardware between the line coupler, the backbone coupler and the repeater they were given the same ordering number
•  After down-loading the physical address the function of the coupler is assigned automatically
