The e:cue Butler S2 is a DMX engine that can be used either in standalone mode to replay and loop previously uploaded lighting shows, or as a DMX output device controlled by another e:cue server with an e:net connection. It is programmed using a PC or the e:cue Lighting Control Engine running the e:cue software suite. One compact Butler controls up to 1024 DMX channels in two DMX universes. Up to 99 cuelists for shows in standalone mode are stored on an micro SD card. The DMX channel control can be increased to 16,384 channels by clustering more Butler S2s. The Butler is powered by an external power supply with 12 to 24 V DC or via 48 V DC PoE (Power over Ethernet). A 7- segment LED is used for message and status display.
