KNX area line coupler or line amplifier REG plus Features: The area line coupler connects two KNX lines with each other in terms of data technology and ensures galvanic isolation between these lines. This means that each bus line in 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 the main line and line (long frame support from ETS5). Area line coupler: Use as an area or line coupler depending on the assignment of the physical address and parameterization. Reduction of the bus load through the filter function (filter table). Forwarding of group telegrams can be parameterized. Repetition rate in the event of transmission errors. Telegram confirmation can be parameterized. Support of the fully expanded group address range from 0 to 31 with the functions 'block', 'forward unfiltered' and 'filter' in both communication directions between the main and sub-line. The 'forward unfiltered' and 'block' functions can also be selected for physically addressed telegrams between the main and sub-line in both communication directions (programming and sabotage protection). The 'repeat: yes no' function in the event of transmission errors on the main or sub-line can be set separately for the 'broadcast' telegram type. Telegram confirmation on the main or sub-line with the settings 'always' and 'only when forwarded' is 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, lines can be extended to a maximum of four line segments (max. three line amplifiers connected in parallel per line) with up to 64 participants each. Repetition rate in the event of transmission errors. Notes: A separate power supply is required for each line (area line, main line, line) or each line segment.
