are you referring to the USB version?
or to the ethernet version? (ODE)?

the ODE can be run using an DMX (Network Artnet Sender)

But, can’t get any of the little_cat or schwartzpeter’s app to control them.

Hi ! Seejin, could you be more explicit ?

wich version of schwartzpeter did you use , that is not working with an enttec Open ?
are you under vista or xp ?

be aware that a set of CD 3 years ago were not at all ok for their drivers. You may download latest drivers on enttec site, in case of. there was troubles with ftdii drivers when passing to SP3.

did u ry your open with freestyler ? if same problem occurs, means you dont have drivers correctly installed
