“Filter” (default option; telegrams will be filtered, dropping the corresponding
ones; see section 2.1.1).
Note
:
transmitting all the telegrams (no telegram filtering or dropping) is only
intended for testing purposes and may cause risks or conflicts in the KNX
installation if permitted permanently
.
Physical: Repetition if Errors on Main Line
: sets the desired reaction upon
transmission errors in the mainline (e.g.: busy receiver, acknowledgement not
received, negative acknowledgement, etc.) of telegrams destined to physical
addresses. The options are “No” (the undelivered telegram will not be re-
sent), “Normal” (default option; the undelivered telegram will be re-sent up to
3 times) and “Reduced” (the undelivered telegram will be re-sent once).
Group: Repetition if Errors on Main Line
: sets the desired reaction upon
transmission errors in the mainline (e.g.: busy receiver, acknowledgement not
received, negative acknowledgement, etc.) of telegrams destined to a group
address. The options are “No” (the undelivered telegram will not be re-sent),
“Normal” (default option; the undelivered telegram will be re-sent up to three
times) and “Reduced” (the undelivered telegram will be re-sent once).
Telegram Confirmations on Line
: sets when the line coupler should confirm
(by sending an immediate ACK message) the reception of telegrams.
Selecting “If routed” (default option) will make the line coupler respond with
an IACK message only if the received telegram is routed towards the
mainline, while “Always” will make the line coupler send a confirmation for
every telegram it receives, even if not routed to the line on the other side.
Send Confirmation on Own Telegrams
: permits enabling (“Yes”) or
disabling (“No”; default option) self-acknowledgment. This extra feature offers
the possibility to send an ACK to the destination line immediately after
passing the telegram itself, so the telegram will show as confirmed on it
(therefore preventing repetitions in case of faulty projects, etc.) even if no
device is receiving it. In case of reception errors on the destination line,
negative ACKs sent by the devices will overwrite this ACK, so having this
parameter enabled will cause no damage or information loss.
