1.2 Function

Media couplers are the link between a specific KNX RF environment (RF = Radio Frequency)
and a wired KNX TP installation (TP = Twisted Pair). With regard to the routing property of
telegrams, media couplers function like standard TP backbone/line couplers. This means that
RF devices can communicate with TP devices via a media coupler or (with additional IP area
couplers) with IP devices and vice versa.
Media couplers possess filter settings and filter tables. The physical address defines whether a
media coupler is a line coupler or a backbone coupler. The exact function of the device is
determined by the selected parameterization and by the physical address.
Optionally, the Gira media coupler can additionally or alternatively work as an repeater. 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 Gira media coupler is a device which allows the media type RF on the lower-level line and
the media type TP on the higher-level line. As of version 5, the device can be configured and
commissioned using the ETS. The device is powered via a KNX TP bus connection (KNX power
supply unit) or alternatively, via a suitable external DC power supply unit in repeater operation
(see chapter 1.3. Accessories).
