Usangreen USB to DMX Interface Adapter LED DMX512 Studio Computer PC Stage Light Controller Dimmer FT232RL RS485 3PIN XLR Serial Converter Cord Support Win10 (6ft, Transparent USB Shell)

Works just fine out of the box. One thing to watch for is that it is susceptible to EMI interference. You'll want to make sure it's isolated from anything that's noisy or you might experience some flickering on your light fixtures.

Works as described, may have a bit of lag, or it could be in my cables, either way if you a shopping for an entry level DMX interface to learn on this item works as it should.
