EIB/KNX Devices
From LinuxMCE
To connect LinuxMCE (with the "old" driver) with your EIB/KNX environment you MUST use a serial bus connector. I use a Berker FT1.2 (order nr. 750600xx).
If you try to use the new driver, you can use any connector because it works with eibd (EIB/KNX with eibd).
EIB/KNX over Powernet
There is no direct serial bus connector for EIB over Powernet. One way to circumvent this problem, is to use a "Systemkoppler 6987/10" from Busch-Jäger.
The Systemkoppler is used to connect EIB over Powernet to an EIB over Twisted Pair installation. All telegrams pass easily between those installs.
The 6987/10 can be used as a PSU for the TP bus for up to 5 TP devices.
