Serial Decoding for KNX Bus

Post by lambdaSky »

Hello all,

is there a way I can decode KNX / EIB bus messages on the TwistedPair medium via PicoScope?

Here some resources about datagramm format (unfortunately german):
https://wiki.production-partner.de/lich ... chitektur/

Here some basic info from Wikipedia:
https://en.wikipedia.org/wiki/KNX_(stan ... )_overview

Here some introduction also covering the the Twisted Pair Physical Layer:
https://www.knx.org/wAssets/docs/downlo ... ics_en.pdf

The serial decoder does not have this option, is another option suitable so I could at least see the hex values?

Thank and best, lambdaSky

Hello,

Here are some captures of a KNX signal.

Tell me if you need more.

Thanks

google translated it for you.
There are more documents out there but this one is the most extensive I have seen.
