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.
