Prior to this device, I had always used USB to DMX adapaters for the variety of small church and theater systems I had configured. However, I needed to extend our normal DMX control system into additional universes, and this device seemed to fit the bill. Just connect up a wired network connection, set the IP address, and then point your Lighting Control software Artnet settings to that IP.
One VERY important note, the Universe settings on this device start at ZERO. That means that the first Universe of DMX data will be called 0 on this device, but is likely called Universe 1 on your Lighting Control Software. This one detail consumed WAY too much time for me to finally figure it out (and if the very scant documentation that comes with this device mentioned it - I sure didn't see it).
Other than that, it seems to be working great! (I'm going back to get another one)
