Operation and installation manual
CO K5X 002 – KNX RF/TP Coupler
Application
The KNX RF/TP Coupler is a compact KNX radio coupler. It
connects KNX RF devices of a radio line with the KNX Bus
Twisted Pair.
The device has a filter table for group addresses. The coupler
supports long frames and is compatible with the ETS® software
ETS5 or higher.
The buttons on the front panel allow disabling the telegram filter
for testing purposes. The LEDs indicate operating conditions as
well as communication errors on the KNX bus.
The power is supplied via the KNX bus.
Coupler function
KNX RF/TP Coupler as line coupler
The individual address assigned to the KNX RF/TP Coupler in
the form of x.y.0 (x, y: 1..15) sets up, that the device operates as
a line coupler.
The KNX RF/TP Coupler has a filter table and thus contributes to
reducing the bus load. The filter table supports the extended
group address range (main group 0..31) and is automatically
generated by the ETS.
Installation and Connection
The device can be flush-mounted, the housing fits into a stan-
dard flush-mounted box.
When choosing the installation location the range of RF devices
to be associated with the gateway has to be considered. Shield-
ing objects (e.g. metal cabinets) or interfering transmitters (e.g.
computers, electronic transformers, ballasts) near the gateway
should be avoided.
The connection to the KNX bus is made with a bus connector.
The correct polarity of the terminal referred to the printing inside
the unit has to be considered.
The KNX RF/TP Coupler features the following controls and
displays:
An external power supply is not necessary as the device is
powered by the KNX bus.
The device is not working without bus power.
