DMX In
You can use DMX512 levels from another source, such as another
console, to control a show in your console. When DMX512 information is
used as input to your console, it is called DMX In.
There may be circumstances where you want to obtain a “snapshot” of
current levels of DMX In, such as if you want to use a particular look on
stage that has been established by another console. For that purpose, you
may record current levels of DMX In into cues or other program elements
in your console.
You may also use DMX In levels to set channel levels dynamically in your
console. In that application you would refer to DMX In as focus point 0. As
DMX In varies, any channel levels set with reference to focus point 0 will
automatically and immediately update, just as they would do if recorded
with reference to any other focus point. 8
The first step in using DMX In for either purpose is to enable DMX In. The
enabling procedure is given in the following section. You can refer to focus
point 0 in your commands without first enabling it, but levels will not be
set in cues or other recorded elements that reference focus point 0 until
DMX In is enabled.
Enabling DMX In
Record DMX In directly and use focus point 0 to set levels after assigning
a starting channel for DMX In. The assignment of a starting channel is
known as enabling DMX In, and is accomplished in the Options Settings
display shown below. 9

Even though focus point 0 functions like any other focus point, you
cannot create it or record to it using the procedures given in Chapter
12 Focus points, page 147.

DMX In is disabled by default.
