When I try to use ArtNet interface DMXC3 sends weird random data to it. In attachment is Wireshark dump. There is ArtPoll, ArtPollReply and some ArtDMX data and again: ArtPoll, ArtPollReply and some data. Data is send without my activity. Light react with random movements and lighting. The same interface with Freestyler, QLC+ and Onyx works well.
What should I do?
