This product is a scaled-down, entry-level version of my DMX 2.0. Out of the package, myDMX software will run in limited mode (No 3D visualizer, Easy Remote or Midi features). However, these features plus other upgrades can be purchased. The product dongle plugs directly into a 3-pin DMX input on your lighting fixture or can be connected to a standard, 3-pin DMX cable to extend your data run. The dongle connects to a computer via a USB connection. Fixture library includes over 10,000 fixture profiles from over 500 manufactures compatible with Mac OS and Windows - easy setup, programming, and playback. We are an authorized American DJ dealer.
