How to set/check PiFace ports for openHAB?

I tried to use the PiFace on my Raspi which I can do on command line using Python.

When I activate the PiFace binding and items I get:

2016-01-02 15:20:17.251 [ERROR] [.piface.internal.PifaceBinding] - Failed to send command (14) to (attempt 3) Receive timed out

at org.openhab.core.service.AbstractActiveService$ [org.openhab.core_1.7.1.jar:na]

So the message is quite clear, raspberry does not listen on these ports. But where do I set them or what needs to be started on raspi to establish these listeners?

After intensive search I found that the scripts I found and used where oudated. Accidentally I found the link on the piface binding page which points to the right files.

For anyone with the same difficulties I summarized it in a post in my blog (german only).

do you know if this binding works with a Piface Digital 2? Or is it required to use the first version of the PiFace Digital?

FYI: the binding works fine with Piface Digital 2. Successfully integrated our Ei Electronics Smoke Detectors into openHAB…
