1 Application
The KNX RF/TP Coupler 673.1 secure is a compact KNX radio coupler. It connects KNX RF
devices of a radio line with the KNX Bus Twisted Pair.
The device has an extended filter table for main group 0 … 31. The coupler supports KNX Long
Frames and is compatible with the ETS® software ETS 5 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.
The device supports KNX Data Security. The functionality of Security Proxy and Segment Coupler
is only supported with the ETS 6 database.
2 Installation and connection
Mounting can be recessed in the wall and thus almost
“invisible”, because the housing has the
right size for mounting in a standard flush-mounted box.
When selecting the mounting location, the range of the radio devices to be connected to the device
must be taken into account. Shielding objects (e.g. metal cabinets) or interfering transmitters (e.g.
computers, electronic transformers, ballasts) near the gateway should be avoided.
The device is connected to the KNX bus using a bus terminal. The correct polarity of the terminal
according to the marking on the device must be observed.
