Hi,
I am using STKNX interface circuit on my KNX device below and i am facing with a strange problem. My device is working clearly on a KNX line but, when i plug a parallel twisted pair cable to my device KNX input (the other side of cable is open i.e there is no device on the other side), it can not work clearly, it does not send any data to KNX bus line. Any advises ??
