Also connect DTR !
ETS activates DTR before it starts communication to a device.

At best, you connect ALL wires 1-to-1, not just the ones given.

The ones given are used for the data communication, but some existing EIB RS232 devices draw power from the other lines as well.

This can be done with normal, commercially available cables. Just DON'T use a so-call null-modem cable. If you make the cable yourself, a simple flat-cable with snap-on connectors will do.
