1 Safety instructions
Electrical devices may only be mounted and connected by electrically skilled
Serious injuries, fire or property damage possible. Please read and follow manual fully.
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.

System information
This device is a product of the KNX system and complies with the KNX directives. Detailed
technical knowledge obtained in KNX training courses is a prerequisite to proper understanding.
KNX RF radio converter
The range of a radio system depends on various external circumstances. The range can be
optimised by the choice of installation location. The product documentation for this device
contains application basics for the KNX radio system.
Planning, installation and commissioning are carried out with the aid of KNX-certified software
of version ETS5 or higher. You can find the up-to-date product database, technical descriptions
and Declaration of Conformity on our Internet site.
Simplified Declaration of Conformity
Hereby Albrecht Jung GmbH & Co. KG declares that the radio system type
Radio converter,
Art. No. MK100RF
corresponds to the directive 2014/53/EU. The complete text of the EU Declaration of Conformity

Operation as media coupler
The physical address of the media coupler is the address of a line or a backbone coupler
x.y.0and must agree with the logical topology of the KNX system. Observe the instructions in
the technical documentation regarding the address.
Power is supplied via the KNX bus cable.
i With operation as a media coupler, the repeater function can also be activated.
Operation as repeater
The physical address of the radio repeater is the address of a normal KNX participant x.y.z
(z≠0) within the address range of the KNX radio system. Observe the instructions in the
technical documentation regarding the address.
Power is supplied via a separate power supply (accessory) or via the connection to a KNX line.
i Do not use the 30 V output of a KNX power supply. The media coupler may heat up to an
impermissible temperature.
i Repeater mode is active after the physical address is assigned. Once this happens,
programming via bus line is blocked. Then the device can only be reached by radio. To
address the device via the bus line, reset the device to default settings.
4 Information for electrically skilled persons
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.
4.1 Fitting and electrical connection
Selecting installation location
To ensure good transmission quality, keep a sufficient distance from any possible sources
of interference, e.g. metallic surfaces, microwave ovens, hi-fi and TV systems, ballasts or
KNX RF radio converter
Do not mount the media coupler near the earth or ground.
Do not place KNX RF devices in small metallic distributors or boxes.
If several adjacent media couplers are used, place them so their radio ranges either do not
overlap at all, or so they can receive each other. Check within a system to see if a media
coupler can be configured as a repeater.
i Media couplers must be accessible even after installation.
Mounting and connecting the device
Mount in flush-mounted or surface appliance boxes.
i In outdoor installations: Use appliance box IP55.
Do not lead any wire cables from other power circuits through the appliance box.
Do not lead any other sheathed cables through the appliance box.
Operation as media coupler:
o Connect device to KNX bus cable via a bus terminal.
Operation as repeater:
o Connect the device to a separate power supply via a bus terminal.
o Place the device in the appliance box.
o 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 arrangement.
i When using blank covers, make sure the antenna does not lie directly behind the metal
supporting frame.
4.2 Commissioning
Loading the physical address and application software
Precondition: Device has been connected and the power is switched off.
o Press the programming button.

The status LED goes out.
o Download the filter table and parameters.
Reset the media coupler to default settings
Disconnect device from bus or power supply.
Press and hold programming button (2).
Connect device to bus and/or switch on power.
The status LED (3) flashes red slowly.
The device is in safe-state mode.
Release the programming button.
Press programming button (2) again and hold about 20 seconds until status LED goes out.
Release the programming button.
The status LED (3) flashes red -> yellow once.
The device is reset to default setting.
