This lower level depiction of a DMX link is how all DMX intelligent fixtures operate. In order to
demonstrate this more clearly, we can look at a typical lighting display example. A user
incorporating a DMX controller to communicate to a fixed number of units is a very standard
and understood application and can be illustrated as follows:

The above example illustrates a typical DMX application where each intelligent fixture requires
a specific DMX Address in conjunction with an appropriate DMX Personality setting. Notice a
terminator is also properly installed in order to maximize signal integrity. With this setup a
user can successfully transmit DMX data from his/her master controller and control each
fixture according to the manufacturer’s operat
ional capabilities when assigned a 3Chn DMX
Personality.
Proprietary Enhancement to DMX512-A
The DS-FX9 operates differently. Instead of employing a standard multi-drop RS-485
network, a Point-to-Point RS-485 link is utilized.
