I am using an Arcus-EDS KNX-GW-IP-2TE now, and the module written by Donald.Peter works fine with this gateway.
This module doesn't need ETS5 for configuration, it has a handy web interface.
Thank you Donald.Peter, you saved me weeks of coding.
is knx multicast address (22.214.171.124) supported in your module?
We have had good experiences with Weinzierl KNX BAOS modules:https://www.weinzierl.de/index.php/en/all-knx/knx-devices-en
The BAOS protocol for them is pretty well documented:https://www.weinzierl.de/images/download/development/830/KnxBAOS_Protocol_v2.pdf
I used the Commtec gateway in more then 50 projects. All the gateways are still working well and stable. But it's not available anymore.
OK, now I tested the brandnew Serial and IP Gateways from the german AMX distributer. Here is the link:https://audiopro.de/de/30362.html
the serial gateway can handle up to 1000 KNX addresses and the IP version can handle 3000 addresses. In my actual project I control 1950 addresses and everything works fine and stable.
There are some more intersting features:
