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.

Repeater Function
The KNX LineCoupler 650 can also be used as a repeater. In
this case, the individual address has the form x.y.z, where z
must not be equal to 0. The filter settings in the parameter dialog
of the ETS are ineffective in repeater mode.

Installation and Connection
The KNX LineCoupler 650 is designed for installation on a DIN
rail with a width of 1 unit (18mm). It features the following con-
trols and displays:
An external power supply is not necessary as the device is
powered by the KNX bus.
The device is not working without bus power (main line).
KNX Programming mode
The KNX programming mode is activated/deactivated either by
pressing the flushed KNX programming button ❸ or by simulta-
neously pressing the buttons ❼ and ❽.
Manual operation and status display
The KNX main line LED ❹lights up green if the device is suc-
cessfully powered by the KNX bus. This LED indicates telegram
traffic on the KNX bus by flickering.
Communication failures (e.g. repetitions of telegrams or telegram
fragments) are indicated by a short change of the LED color to
red.
Overview of the different indications of KNX main line LED ❹:
The KNX sub line LED ❻ lights up green when the device is
ready for operation (supplied by the main line) and the KNX bus
voltage is present on the sub line. If the LED is flickering, tele-
gram traffic takes place on the sub line.
Errors in the communication (such as telegram repeats or tele-
gram fragments) are indicated by a short-time color change to
red.
Overview of the different indications of KNX sub line LED ❻:
For testing purposes (for example, during commissioning) the
configured routing settings (filter or block) can be bypassed via
manual operation.
With the button “Pass GAs”❼the forwarding of group ad-
dressed telegrams can be activated.
With the button “Pass IAs”❽the forwarding of individually
addressed telegrams can be activated.
This is visualized with a single flash of the Mode LED ❺ (or-
ange). If both modes are activated the Mode LED ❺ flashes two
times.
Pressing button “Pass GAs”❼or button “Pass IAs”❽again
these settings can be selected and deselected on demand. Via
the Escape function (Esc) the manual operation can be stopped
by simultaneously pressing the buttons “Pass GAs”❼and
“Pass IAs”❽.
If neither programming mode nor manual mode are active the
LED ❺ can visualize configuration errors (for details see table
below).
