The area/line coupler connects two KNX lines to each other for data transfer and ensures electrical isolation between these lines. As a result, each bus line of a KNX installation can be operated electrically independently of the other lines.
Support for KNX Data Secure communication (KNX Data Secure telegrams can be processed and filtered, forwarded or blocked according to the settings).
Fast communication between KNX products in main line and line (long frame support for ETS5 and higher).
Area/line coupler
Use as an area or line coupler, depending on the specification of the physical address and parameterisation.
Reduction of the bus load via filter function (filter table).
Forwarding of group telegrams can be parameterised.
Repetition rate in the case of transfer errors.
Telegram confirmation can be parameterised.
Support for the fully expanded group address area from 0 to 31 with the functions “block”, “forward unfiltered” and “filter” in both directions of communication between the main line and subline.
“Forward unfiltered” and “block” functions can also be selected for physically addressed telegrams between the main line and subline in both directions of communication (programming and tamper protection).
"Repeat: yes/no" function can be set separately for the telegram type "Broadcast" in the event of transmission errors on the main line or subline.
Telegram confirmation on the main or subline with the settings "always" and "only for forwarding" possible separately for group telegrams and physically addressed telegrams.
For physically addressed telegrams, the setting “always reject NACK (Not-Acknowledge)” can be selected (programming protection with feedback).
Line amplifier
As a line amplifier, extending the lines to max. four line segments (max. three line amplifiers per line connected in parallel per line) with up to 64 devices each is possible.
Repetition rate in the case of transfer errors.
