Area line coupler or line amplifier for KNX DRA plus Features: 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. Supporting KNX Data Secure communication (KNX Data Secure telegrams can be processed, then filtered, forwarded, or blocked depending on the settings). Rapid communication between KNX products in main line and line (long frame support from ETS5). 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 of the completely expanded group address area from 0 to 31 with the functions "block", "forward unfiltered", and "filter" in both communication directions between the main and subline. "Forward unfiltered" and "block" functions can also be selected for physically addressed telegrams between main and subline in both communication directions (programming and tamper protection). "Repeat: yes no" function can be set separately in case of transfer errors on the main or subline for the telegram type "Broadcast". Telegram confirmation on the main and subline possible separately for group telegrams and physically addressed telegrams with the settings "always" and "for forwarding only". 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. Notes : A separate power supply is required for each line (area line, main line, line) or each line segment.
