Page 7: Function As Line Or Area Coupler
(max. 225 routers) Line The KNX LineCoupler 650.1 secure has a filter table and therefore helps to reduce the bus load. The filter table supports the extended group address range (main groups 0 … 31) and is automatically generated by the ETS. - Page 8 4.1.1 Line coupler The individual address of the KNX LineCoupler 650.1 secure corresponds to the form x.y.0 (x, y: 1 … 15). Thus the device functions as line coupler. The device functions as line coupler only if its individual address has the form x.y.0.
- Page 9 4.1.2 Area coupler The individual address of the KNX LineCoupler 650.1 secure corresponds to the form x.0.0 (x: 1 … 15). Thus the device functions as area coupler. The device functions as area coupler only if its individual address has the form x.0.0.

Page 10: Function As Segment Coupler
4.2 Function as segment coupler The individual address of the KNX LineCoupler 650.1 secure corresponds to the form x.y.z (x, y: 1 … 15, z: 1 … 255). Thus the device functions as segment coupler. The device functions as segment coupler only if its individual address has the form x.y.z. -
Page 11: Function As Repeater (Only With Ets5)
4.3 Function as repeater (only with ETS5) The individual address of the KNX LineCoupler 650.1 secure corresponds to the form x.y.z (x, y: 1 … 15, z: 1 … 255). Thus the device functions as repeater. The filter settings in the parameter dialog of the ETS are ineffective in repeater mode. -

LineCoupler 650.1 secure (www.weinzierl.de) or from the ETS online catalogue. The KNX LineCoupler 650.1 secure supports KNX Data Security to protect the device against unauthorized access from the KNX bus. If the device is programmed via the KNX bus, this is done with encrypted telegrams. - Page 14 The initial key is reactivated after a reset to factory default settings. The serial number in the certificate enables the ETS to assign the correct key to a device during a download. © 2024 WEINZIERL ENGINEERING GmbH Seite 14/26...

Page 15: Secure Group Communication
6.4 Secure group communication Each object of the device can communicate either encrypted or unencrypted. The encryption is set under "Security" in the properties of the used group address: © 2024 WEINZIERL ENGINEERING GmbH Seite 15/26... - Page 16 ETS e.g. when the encryption of a group address is switched off and on again. Telegrams from the bus that do not address the KNX LineCoupler 650.1 secure as a device are forwarded or blocked according to the filter settings (parameters and filter table).
