Doug Fleenor Design makes a series of selector switches specifically designed to switch DMX512 signals.
Doug Fleenor Design Switch Boxes consist of a high reliability switch (rocker or rotary) wired to Neutrik five pin gold plated XLR style connectors (three pin or terminal block optional). The units are housed in metal enclosures of appropriate size and are rack mountable (with optional rack ears). The standard units switch the Data+ and Data- lines. Custom units can switch any or all contacts. Custom "remote switch" units using relays in place of the manual switch are also available.
Originally designed to switch between primary and backup consoles, these switches are often used to select from two (or more) input locations. The model SW1 switches a single DMX512 universe (one A input, one B input, one output). SW 2 switches two DMX512 universes, SW3 switches three DMX512 universes, and SW4 switches four DMX512 universes (four A inputs, four B inputs, four outputs).
Custom units for switching any number of universes are available. Custom units for switching between more than two input sources are available (A/B/C switches, for example). Please contact StageSpot directly at 888-56-STGE for custom configurations. A/B Switch Box Data Sheet A/B Switch Box Drawings
