I believe that you would need to use an e:cue artnet upgrade dongle for artnet input into LC -

Or for straight dmx, a dmx interface box from e:cue along with one of our dmx interfaces -

As far as a direct connection using e:cue e-net, I don't think this is possible right now. Dmitriy will clarify this when he returns to the office.
