JVL can now deliver a module with DMX512
opto isolated RS485 interface for Integrated
Servo Motors from
50 to 4500 W. DMX512 are mostly used for application in stage lighting, special
effects and theatre but can also fast and efficiently control up to 512 motors
from the same DMX master.

DMX512 (Digital Multiplex) is a standard for digital communication networks that are
commonly used to control stage lighting and
effects. It was originally intended as a standardized method for controlling
light dimmers, which, prior to DMX512, had employed various incompatible proprietary protocols. It soon became the
primary method for linking controllers (such as a lighting console)
to dimmers and special effects devices such as fog machines and intelligent lights. DMX has also expanded to
uses in non-theatrical interior and architectural lighting, at scales ranging
from strings of Christmas lights to electronic billboards. DMX can now be used
to control almost anything, reflecting its popularity in theatres and venues.
DMX512 employs EIA-485 differential
signaling at its physical layer, in conjunction with a variable-size,
packet-based communication protocol. It is unidirectional.
DMX512 does not include automatic error
checking and correction, and so is not an appropriate control for hazardous
applications, such
as pyrotechnics or movement of theatrical rigging. False triggering may be
caused by electromagnetic interference, static electricity discharges,
improper cable termination, excessively long cables, or
poor quality cables.
