Toggle DMX Passthrough
Imagine this scenario:
In an auditorium or small performance space, there is a Crestron / Control4 / AMX control system installed. Touchscreens or switchpanels are mounted near the doorways. On weekends or during large productions, the lighting designer uses a large-format console or PC to run the show. But for rehearsals, cleaning, etc, only a few different lighting scenes may be required. The DecaBox can easily accommodate this, based on its three DMX connections.
- DMX In can be connected to any upstream controller, such as a lighting console or USB / DMX interface on a PC.
- DMX Through is a passive, parallel copy of DMX input.
- DMX Out is connected to our internal processor.
In passthrough mode, DMX data is copied from input to output. System lag is ~ 1 DMX frame. It's virtually unnoticeable.
P[cr] ... enables passthrough mode. Data is copied from input to output. System delay is ~ 1 frame, or 1/40 second. E[cr] ... tells the DecaBox to ignore DMX input and instead generate its own scenes, based on serial input, stored data, etc.
Thus it can be very straightforward to for in-wall touchscreens, for example, to recall stored DecaBox scenes during the day when unskilled users are present, but for large productions, the lighting crew has complete control.
