Hi Zorn,
Music mode - Uses beat to trigger effects from internal memory.
Auto mode - scrolls those effects automatically.
Do control it with DMX you have to buy DMX desk or computer program with DMX interface. You use (usually 12 channels) to control different parameters.
Every channel controls different parameter that you can find from manual (if you have one - if not ask from Goldenstar)
If you have many of them you can connect them with DMX cabel (plane old XLRm-XLRf will do) and one controls other(s) so they all (as much you have)work synchronized.
