Supported PCD communication ports for EIB/KNX driver

FAQ #100792

For BCU1 protocol not all communication interfaces of a PCD3 or a PCD2.M5540 can be used. On the other hand there is no problem using the newer FT1.2 protocol which is supported by all RS232 interfaces of the PCD3 and the PCD2.M5540.

 

Supported communication interfaces for EIB/KNX driver
The table below shows the supported communication interfaces for connecting an EIB coupler to PCD3-, PCD2.M5540 and PCD1.M2120 systems. On other systems (e.g. PCD2.M170) all RS232 interfaces can be used for connecting an EIB/KNX coupler.

Remark
We strongly recommend using FT1.2 (also known as BCU2) for new projects as this implementation is more performant (due to a higher baudrate supported and telegram oriented transmission control rather than character-oriented transmission control which is used by BCU1). The table above represent functional tests; there is no relation to the communication performance.
