1 Product definition
1.1 Product catalogue
Product name: Radio converter
Use: System device
Design: Installation
Art. No. MK100RF
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 Jung 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 Jung 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).

2 Installation, electrical connection and operation
2.1 Safety instructions
Electrical devices may only be mounted and connected by electrically skilled
persons.
Failure to observe the instructions may cause damage to the device and result in fire and
other hazards.
The radio communication takes place via a non-exclusively available transmission path,
and is therefore not suitable for safety-related applications, such as emergency stop and
emergency call.

2.3 Mounting and electrical connection
DANGER!
Electrical shock on contact with live parts in the installation environment.
Electrical shocks can be fatal.
Before working on the device, disconnect the power supply and cover up live
parts in the working environment.
General
Mount in suitable flush-mounted or surface appliance boxes.
iIn outdoor installations: Use appliance box IP55.
iDo not place the device in small metallic distributors or boxes.
Do not lead any wire or sheathed cables from other power circuits through the appliance box.
Precondition: To ensure good transmission quality, keep a sufficient distance from possible
interference sources, e.g. metallic surfaces, microwave ovens, hi-fi and TV sets, ballasts or
transformers.
Connect the device and mount it for use as media coupler
The media coupler is connected to and supplied by a KNX bus cable (TP).
Precondition: Ideally, the media coupler is positioned in the centre of an RF installation
(domain), to allow low-loss and thus interference-free communication with all the associated RF
devices.
oConnect device to a KNX bus cable. For this, use a KNX device connection terminal.
Ensure correct polarity.
iIf the media coupler is used as a line coupler, the KNX bus cable must be the main line of a
TP area. If the media coupler is used as area coupler, the KNX bus cable must be the TP
area line (Backbone) of the KNX installation.
oPlace the device in the appliance box.
oWhen 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 arrangement.
iWhen using blank covers, make sure the antenna does not lie directly behind the metal
supporting frame.
Connect the device and mount it for use as a repeater (no media coupler function)
If needed, the repeater can be connected to a KNX bus cable (TP) via which it is supplied, as
long as the bus cable is the TP line of the associated media coupler. Thus the use of the
repeater is especially relevant for retroactive solutions in existing TP systems.
Alternatively, a repeater can also be supplied via a separate DC power supply (see
accessories), even without KNX bus voltage.
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.
oConnect the device to a KNX bus cable or alternatively, to a separate DC power supply.
For this, use a KNX device connection terminal. Ensure correct polarity.
iDo not use the unchoked 30 V output of a KNX power supply! The media coupler may heat
up to an impermissible temperature.

iWhen connecting a TP bus cable, after the physical address is programmed, no direct ETS
program access to the device on the TP side during repeater operation is possible any
longer. Consequently, the repeater can only be programmed and diagnosed (e.g. with the
use of suitable KNX RF USB data interfaces or via another media coupler of the same RF
domain) via the RF side.
oPlace the device in the appliance box.
oWhen 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 arrangement.
iWhen using blank covers, make sure the antenna does not lie directly behind the metal
supporting frame.

2.4 Commissioning
General
Depending on the physical address, the device can be added to the KNX topology either as a
media coupler or alternatively, as an RF repeater, and commissioned. Already the physical
address assignment and programming define the device function.
The device operates as a media coupler when it is given a physical address in the form
x.y.0 (line coupler) or x.0.0 (area coupler) (x = area address, y = line address).
The device operates exclusively as a repeater when it is assigned a physical address in the
form x.y.1...255.
In an RF domain, always commission the media coupler first! Only then should any optional
additional repeaters and all other participants of the RF installation be programmed.
Ideally, install and connect the repeater after the media coupler has been completely
commissioned.
Precondition: An appropriate device must be created and configured in the ETS project. Device
has been connected and the power is switched off.
iProject design and commissioning with ETS5 or a more recent version.
iProgramming mode is deactivated after the physical address has been successfully
programmed, or is generally deactivated by a device test (power failure, ETS programming
process of the application program).
Programming mode is also deactivated automatically after 4 minutes if none of the above
events occurs.
Commissioning as media coupler
As delivered, the device can be programmed and commissioned as a media coupler via the TP
side (e.g. with the use of suitable USB or IP data interfaces) or via the RF side (e.g. with a KNX
RF USB data interface).
iAfter a successful initial commissioning, access to the device for programming may be
restricted because of an active configuration lock (see page 24).
oPress the programming button (2)(figure 1).
The status LED (3) lights up red. Programming mode is activated.
oLoad the physical address into the device. The ETS also automatically loads the domain
address of the RF line into the device.
The red status LED goes out.
iWhen programming the media coupler via RF: For the programming of the physical
address and the domain address to be carried out and completed correctly, the domain
address of the RF line must match the domain address of the RF communication interface
(e.g. KNX USB RF data interface)! Otherwise, communication errors can be expected.
The domain address of the KNX RF USB data interface used by the ETS is configured in
the general connection settings of the ETS. In an ETS project, the domain address of an
RF line or a media coupler is configured in the line properties (separate for each RF line).
oLoad the application program into the device using the ETS.
iThe filter table is automatically loaded to the device together with the application program
via the ETS. Whether or not the filter table is used for routing group telegrams in media
coupler operation is defined by the device parameters.
In pure repeater operation, the filter table has no function.
Commissioning the device as a repeater
The device can only be programmed as a pure repeater (no media coupler function) and
commissioned via the TP side to a limited extent (e.g. with the use of suitable USB or IP data
interfaces, if the device is connected to the TP line of the associated media coupler).

Installation, electrical connection and operation
Art. No. MK100RF
Programming access to the device via the RF side is always possible with no limitation (e.g.
with a KNX RF USB data interface or via a media coupler).
After the physical address is programmed, a repeater can no longer be reached directly via the
TP side. As a result, further programming operations using the ETS can no longer be executed
on the TP side without the media coupler. Direct access to the device via the TP side is only
possible again when the device is reset to delivery state (see page 27).
Program the physical address and the application program always separately.
oPress the programming button (2)(figure 1).
The status LED (3) lights up red. Programming mode is activated.
oLoad the Physical Address to the device via the TP side (if the device is connected to the
TP line of the associated media coupler) or the RF side. The ETS also automatically loads
the domain address of the RF line into the device.
The red status LED goes out.
iAfter the physical address has been successfully programmed, the device can no longer be
reached with the ETS via the TP side, because the device's TP transponder is switched off!
This feature is necessary because from a topological standpoint, a repeater (without media
coupler function) is exclusively assigned to the RF line, and no longer to a TP line.
Consequently, afterwards the application program can only be programmed separately via
the RF side. To do so, either a programming connection via the media coupler of the RF
domain can be used (TP -> RF) or alternatively, a KNX RF USB data interface.
Where necessary, the TP line of the media coupler can be used for power supply to the
repeater (see page 7-8).
iWhen programming the repeater via RF: For the programming of the physical address and
the domain address to be carried out and completed correctly, the domain address of the
RF line must match the domain address of the RF communication interface (e.g. KNX USB
RF data interface)! Otherwise, communication errors can be expected.
The domain address of the KNX RF USB data interface used by the ETS is configured in
the general connection settings of the ETS. In an ETS project, the domain address of an
RF line or a repeater is configured in the line properties (separate for each RF line).
oLoad the application program into the device using the ETS.
iIn pure repeater operation, the filter table has no function.
