Use purely as an RF repeater is only possible in RF lines, but not in lower-
level RF segments.
Precondition: The repeater is positioned within radio range of the media coupler and
ideally within radio range of another repeater of the same RF domain, to allow low-
loss and thus interference-free communication with all the associated RF devices.
￭
Connect the device to a KNX bus cable or, alternatively, to a separate DC
voltage supply. For this, use a KNX device connection terminal. Ensure correct
polarity.
Do not use the unchoked 30 V output of a KNX voltage supply! The media
coupler may heat up to an impermissible temperature.
In the case of a device with the marking "I04" or higher, the "Repeater-Prog-
mode" of the device must be activated before the physical address is pro-
grammed.
In the case of connection to a TP bus cable, direct ETS program access to the
device via the TP side during repeater operation is no longer possible after
commissioning. Consequently, the repeater can only be programmed and dia-
gnosed (e.g. with the use of suitable KNX RF USB data interfaces or via an-
other media coupler of the same RF domain) via the RF side.
￭
Place the device in the appliance box.
￭
When laying the antenna, extend the antenna extended as much as possible.
If this is not possible, position the antenna behind the device in a circular ar-
rangement.
When using blank covers, make sure the antenna does not lie directly behind
the metal supporting frame.
