Compact KNX Line Coupler TP/TP
KNX LineCoupler 650
Application
The KNX LineCoupler 650 is a KNX line coupler in a compact
design. It connects two KNX bus segments (for example, a KNX
line with a KNX area).
The device has a filter table (8k bytes) and ensures a galvanic
separation between the lines. The coupler supports KNX long-
frames and is compatible with the ETS® software (ETS3 or
higher).
The buttons on the front side allow to deactivate the telegram
filters for test purposes. The LEDs indicate operating conditions
as well as communication errors on the KNX bus.
The power is supplied via the KNX bus (main line).
Coupler function
The KNX LineCoupler 650 operates as a line or backbone cou-
pler. In both cases, KNX TP is used as a backbone.
The following table shows the application possibilities of the KNX
LineCoupler 650 compared to the IP based topology:

KNX LineCoupler 650 as line coupler
The individual address assigned to the KNX LineCoupler 650
determines whether the device operates as a line or area cou-
pler. If the individual address is in the form of x.y.0 (x, y: 1..15),
the device operates as a line coupler. If it is in the form of x.0.0
(x: 1..15), the router acts as a backbone coupler.
KNX LineCoupler 650 as area and line coupler
The KNX LineCoupler 650 has a filter table and thus contributes
to reducing the bus load. The filter table (8kB) supports the
extended group address range and is automatically generated
by the ETS.
