The Xpress 512 DMX-512 USB Interface from Chauvet is a self-contained unit providing one universe of data from a computer or USB-equipped lighting board. The user can control many universes by connecting multiple USB cables to as many Xpress 512's as are needed. In addition, the Xpress 512 has sufficient software onboard that the operator can easily store and playback one show without a computer. This unit is compatible with both Windows and Mac OS X operating systems.
