Physical address of device
x = area
y = line
x.y.0 (media coupler)
x.y.1...255 (RF repeater)
This parameter is only available in the ETS application program "Media
coupler / repeater 902011".
Depending on the physical address the device can be inserted either as a media
coupler or, alternatively, as a repeater in the KNX topology. Already the physical ad-
dress assignment and programming define the device function. The following para-
meter must also be configured for the appropriate use.
x.y.0 (media coupler)
The device works as media coupler. Depending on the allocated physical address,
the media coupler operates as either an area or a line coupler. The device operates
as a line coupler when it has a physical address in the form x.y.0 (x = TP area ad-
dress, y = TP line address / e.g. "1.1.0"). Then the media coupler is connected to the
main TP line of an area. The device operates as a backbone coupler when it has a
physical address in the form x.0.0 (x = TP area address, e.g. "1.0.0"). In this case,
the backbone must be media type "TP".
There may only ever be one media coupler in an RF line.
x.y.1...255 (RF repeater)
The device operates exclusively as a repeater, without media coupler function. A re-
peater repeats the radio telegrams received in its RF line by retransmitting them im-
mediately. This allows an extension of the range of a KNX RF installation, meaning
that it is possible to position RF devices as required in a building, even in the case of
difficult transmission and reception conditions.
Repeaters working in an identical RF domain must have the same area ad-
dress (x) and line address (y). Multiple repeaters can be added to an RF line.
Repeater function when used as media
coupler
deactivated
activated
In media coupler function mode, the device can also repeat telegrams from its own
RF domain. Like in an independent repeater mode, this allows the range of a KNX
RF installation to be extended, meaning that it is possible to position RF devices as
required in a building even in the case of difficult transmission and reception condi-
tions.
Repeater function when used as segment
coupler
deactivated
activated
In segment coupler function mode, the device can also repeat telegrams from its
own RF domain. Like in an independent repeater mode, this allows the range of a
KNX RF installation to be extended, meaning that it is possible to position RF
devices as required in a building even in the case of difficult transmission and recep-
tion conditions.
