Repeater Function
The KNX LineCoupler 650 can also be used as a repeater. In
this case, the individual address has the form x.y.z, where z
must not be equal to 0. The filter settings in the parameter dialog
of the ETS are ineffective in repeater mode.

Installation and Connection
The KNX LineCoupler 650 is designed for installation on a DIN
rail with a width of 1 unit (18mm). It features the following con-

Manual operation and status display
The KNX main line LED
❹
lights up green if the device is suc-
cessfully powered by the KNX bus. This LED indicates telegram
traffic on the KNX bus by flickering.
Communication failures (e.g. repetitions of telegrams or telegram
fragments) are indicated by a short change of the LED color to
red.

The KNX sub line LED
❻
lights up green when the device is
ready for operation (supplied by the main line) and the KNX bus
voltage is present on the sub line. If the LED is flickering, tele-
gram traffic takes place on the sub line.
Errors in the communication (such as telegram repeats or tele-
gram fragments) are indicated by a short-time color change to
red.
