8.2 Function as repeater
Media/segment coupler with repeater or repeater alone
The media/segment coupler can work as a repeater (also "retransmitter") in addition
to its function as a coupler. A repeater repeats the radio telegrams received in its RF
line by retransmitting them immediately. 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.
The device can only work as a media coupler (see chapter "Function as media
coupler"
}
Page 17), as a media coupler and repeater, or - depending on the applica-
tion program used - as a repeater alone. The operating mode is defined by the para-
meter setting and the physical address.
Only when using the ETS application program "Media coupler / repeater
902011" in RF lines:
The device works purely as an RF repeater if it has a physical address which
corresponds to a normal participant address of the RF line (e.g. x.y.1 or
x.y.200 / x = area address, y = line address) and the parameter "Physical ad-
dress" is also set accordingly.
– Function as media/segment coupler with repeater:
The device has a physical address in the form x.y.0 and works as a coupler
(see chapter "Function as media coupler"
}
Page 17). In addition, the repeater
function can be released with the setting "activated" for the parameter "Re-
peater function ...". The parameter "Physical address of the device" must be
configured to "x.y.0 (media coupler)".
Combined operation of the media coupler and repeater function is helpful if,
within a radio domain, all the RF subscribers are within radio range of the
coupler but are not however in the radio ranges of other RF subscribers. Here,
the repeater integrated in the central media/segment coupler ensures that tele-
grams from RF subscribers also actually reach all the other RF subscribers of
the radio domain.
Application example (see figure 6): Because of the spatial distance, no direct
communication between the two RF devices (1.) is possible. The communica-
tion route via the media coupler with repeater function (2.), however, enables
communication between the two devices without interference.
