Understanding Your Automated Devices
Moving lights, scrollers, fog machines etc., all fall into the family of
automated devices that may be controlled by the console. It is EXTREMELY
important that before you try to use an automated device that you become
familiar with its operation by reading the manual that came with your
device. Learning how each device works as well as how to make them
respond the way you want them to is the first step in working with
automated devices.
AC Power requirements : Some units need power other than 120V power
from a wall plug, or need a "non-dimming" power source.
Mounting Requirements : Simply put, since most of these fixtures move
or at least the beam of light moves, an eye for visual obstructions, space
and physical mounting requirements is a concern.
Device Traits and DMX 512
Device Traits are the specific parameters of a moving light or other
automated device. Examples of device traits could be pan, tilt, color, gobo,
zoom, etc. The traits of a device are controlled by individual DMX data
channels which are output from the console. Before the traits can be
controlled, they must be patched (addressed) to specific dimmer addresses
within the console. When DMX was first used to address only conventional
dimmers, then the "512” means up to 512 dimmers could be addressed
from a single data stream (port). With automated devices, this relationship
changes since a single device may need a number of data channels in order
to operate its traits. The example below is a 7 channel device that uses 2
channels for Pan, 2 channels for Tilt, 1 channel for Color, 1 channel for
Gobo and 1 channel for Dimmer. The DMX start address is 21.
