DMX Primer

Introduction

The Physical Medium

The Signals

DMX Universes

The Functions

The DMX protocol (USITT DMX512-A) is a networking protocol that enab les a
universal DMX controller device to control the features of multiple DMX
compatible fixtures, whether PAR cans, wash lights, moving heads,
followspots, foggers, or proprietary fixture controllers, etc.

As any other networking protocol, the USITT DMX512-A describes the
physical medium, the signals, and the functions they control.

DMX compatible fixtures are connected to the DMX controller using a DMX
connection. This connection consists of a series of wired connections between
the DMX controller and the various DMX compatible fixtures, also kno wn as a
daisy chain connection. In this type of connection, the DATA OUT of one
fixture or the DMX controller connects to the DATA IN of the ne xt fixture, and
so on.

Each DMX fixture links to the previous and next DMX fixture or controller using
a DMX cable. This type of cable consists of a section of shielded, two­conductor twisted pair cable with one 3-pin or 5-pin XLR male connector on
one end, and a 3-pin or 5-pin XLR female connector on the other end. The
XLR connectors pin-out is as follows: pin 1 is the Common (shield), pin 2 is
Signal Negative (S-), and pin 3 is Signal Positive (S+).

Note: For DMX, pins 4 and 5 are not used.

The DMX signal stream is unidirectional from the DMX co ntroller to the DMX
compatible fixtures. These signals conform to the EIA-485 standard.

The stream of DMX signals consists of 512 individual, sequential channels that
form a frame. The DMX controller constantly sends frames of DMX signals to
the DMX connection, even if not all of the 512 channels are in use.

Because of this constant transmission method, there can be only one DMX
controller in a DMX connection. If not, the DMX signals sent by one c ontroller
would interfere with the signals sent by the other controller(s).

A DMX universe is the set of DMX compatible fixtures connected to the same
DMX daisy chain using the same set of 512 DMX chann els. Each set of 512
channels is referred to as a DMX Universe.

In most cases, an installation will consist of only one DMX universe.
However, you might find it necessary to define two or more universes
because of constrains imposed by distance or the number of features.

Most DMX controllers support only one universe, although some DMX
controllers may support two or more universes. Each universe will have its
own separated DMX daisy chain. A DMX c ompatible fixture can only be part
of a single DMX universe.

Each DMX channel can have any unitar y value in the 000~255 range. Each
DMX compatible fixture uses as many consecutive DMX channels as featur es
the user can control. The sequential numbers assigned t o each DMX channel
(1~512) are also known as DMX addresses.

The function each DMX channel has, and the results of a ssigning a value to
each depend on the personality (or DMX channel layo ut) of each controlled
fixture. Some fixtures only use a single DMX channel, while others may
require 15 or more DMX channels to control all their functions. Personalities
are discussed in the next section, DMX Configuration.

Page 16 of 20 Obsession™ LED 2.0 User Manual (Rev. 03)

DMX Configuration

The DMX fixture configuration consists in determining how many channels
each fixture will need as well as assigning the corres pondi n g DM X chan ne ls to
each fixture in order to size correctly the DMX controller.

Personalities

A DMX personality describes what channel or cha nnels control which fixture
parameters. A DMX fixture may have many personalities to choose from. Each
personality requires a different number of channels, based on the numb er of
features the fixture enables. The number of DMX channels used by a fixture
may vary from only one (usually the general dimmer control) to 15 or more.

When a job does not require using all the fixture ’s capabilities, the user can
select a more basic personality (less channels), allowing the DMX controller to
accommodate more DMX fixtures.

Starting Address

For the DMX controller to control each DMX fixture, the user must first
configure each fixture’s personality to determine the number of channels
required to control the fixture. Each channel will have a DMX address
assigned to it.

However, since assigning a particular DMX address to each channel is
impractical, the user will only need to configure the DMX address on each
fixture that corresponds to the fixture’s first channel of control. This is the
fixture’s starting address. The fixture will automatically assign the other
channels to the subsequent DMX addresses.

Once this assignment is complete, and based on the number of channels
used, the fixture will respond to the DMX signals sent to the range of DMX
channels that begins with the starting address.

For example, a fixture that uses six DMX channels with a starting addr ess of
100, will accept DMX data sent by the DMX controller to channels 10 0, 101,
102, 103, 104, and 105.

Assigning Addresses

The user must carefully assign the starting addresses for each individual
fixture to avoid DMX channel overlapping. If the DM X ch annels do overl ap, the
impacted fixtures could operate erratically.

However, the user may decide to configure two or more similar fixtures with
the same personality and starting address. In this case, all the fixtures with the
same starting address will operate in unison.

DMX Connectivity

Connecting the DMX fixtures to a DMX controller in small to medium
installations is usually a rather simple operation that requires a minimum of
tools and some planning (not including the actual fixture rigging and
configuration).

However, in large installations it may be necessary to plan carefully the
position and cabling of each fixture to avoid unexpected probl ems.

Fixture Location

The order in which the fixtures connect to the DM X controller is not important
and has no effect on how a controller communicates to each fixture. However,
the user should always define a physical location for the fixtures that provide s
for the easiest and most direct cabling to the controller and other fixtures.

Obsession™ LED 2.0 User Manual (Rev. 03) Page 17 of 20

(DMXConnectivitycont.)

Number of Fixtures

When using a DMX controller, the combined number of chann els required by
all the fixtures on the DMX daisy chain determines the nu mber of fixtures the
DMX controller has to support. Conversely, the number of onboard sliders,
page buttons, and fixture buttons limits the number of discrete DMX chan nels
a DMX controller can support.

To comply with the EIA-485 standard, which is the base for the USITT
DMX512-A protocol, do not connect more than 32 fixtures witho ut using
an optically-isolated DMX splitter. Doing otherwise may result in
deterioration of the digital DMX signal.

DMX Data Cabling

You must use DMX compliant data cables to link two or more DMX compa tible
fixtures. You may purchase CHAUVET® certified DMX cables directly from a
dealer/distributor or construct your own cable.

USITT recommends limiting the total length of the DMX cable (from the
first fixture/controller to the last fixture) to 300~455 m (985~1,500 ft).

Cable

If you choose to create your own DMX cable, make sure to use d ata-grade
cables that can carry a high frequency signal and are less prone to
electromagnetic interference. Use a Belden® 9841 or equivale nt cable, which

Making Your Own DMX

meets the specifications for EIA RS-485 applications. For certain applications ,
Cat5, Cat5e, or Cat6 may be appropriate.

Do not use standard microphone cables for DMX applications because
they cannot transmit DMX data reliably over long distances.

DMX Cable

Characteristics

DMX Cable Connectors

The DMX data cable must have the following characteristics:

Maximum capacitance between conductors: 30 pF/ft
Maximum capacitance between conductor and shield: 55 pF/ft
Maximum resistance: 20 ohms/1000 ft
Nominal impedance: 100~140 ohms

Each DMX cable must have a male (3-pin or 5-pin XLR connector) on one end
and a female (3-pin or 5-pin XLR connector) on the other end.

DMX Connection

Test all DMX cables with an ohmmeter to verify their correct polarity and
to make sure that there are no short-circuits between an y of the pins, or
between any pin and ground.

If the common wire (shield) touched the chassis ground, a ground loop
could form, which may cause the fixture to perform erratically.

If you use a DMX controller or fixture with a 5-pin DMX connector, you will
need to use a 5-pin to 3-pin adapter. The chart be low details a proper cable
