With this unit, you can record and store a light show, then let the unit playback the show for as long as you like. The DMXPlayBack MK2 is perfect for unattended light shows or demonstrations that run continuously. The unit can store up to 500 static scenes per show. A show can be programmed to start: when the unit is powered, or an external trigger via RS232 can start/stop a show. You could even control the PlayBack from any RS232 capable device. Clients have also used the DMXPlayBack MK2 with a more sophisticated control system such as AMX™ systems, where multiple DMXPlayBacks were used to output DMX512 pre-recorded scenes. Loading and fading of the scenes were commanded from RS232. The DMXPlayBack Mk2 also offers REALTIME control of your lighting fixtures, when you change a parameter on the PalmPilot or PC the changes occur on the DMX output too. You can use it as a debugging tool.
