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.

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.
