Good to see you posting under your true name/company affiliation

Hi Nicolas,
I took another look at the DMX USB Pro I have here and don't see anything like the source termination specified in [2.5 Command port reference circuit]. Maybe I'm missing something obvious here which you could enlighten me about.

If the Enttec RDM USB Pro has no termination then how does it comply when used as a command port? Or is this device purely an RDM sniffer only?

Fixed my signature btw.
