DX3 Manual 4

1 Introduction
The DX3 is a high performance fully digital dimming system capable of controlling up to 512
dimmers. It is designed for theatrical or architectural applications, or a combination of both.
This manual begins by introducing the DX3 system architecture as well as features and how they work.
Please refer to the DxDirector DX3 manual for details on how to set up and program all the features
into your rack.
1.1 DX3 Dimmer Racks
Typical DX3 Racks are shown in Figure 1. This shows the three size racks that characterize the DX3
family. The DX3-120 can hold up to 120 dimmers, the DX3-60 up to 60 dimmers and the DX3-30 up
to 30 dimmers. These dimmers can be a combination of regular phase control SCR dimmers, reverse
phase IGBT dimmers or non-dim relays. Most dimmer/non-dim modules are dual modules. Racks are
typically 3-phase, but can accommodate single phase. Both 120/208vac and 277/480vac rack systems
are available.

1.2 DX3 Architecture
The DX3 rack takes in the following protocols:
Two DMX512A data links
Three Lehigh Collage architectural links for up to 128 zones of control over 16 areas
On-board Ethernet for rack communication or DMX over Ethernet
Dry contact for fire alarm input
On-board bypass switch to allow dimmers to turn on without the electronics module
Additional I/O modules are available for numerous other input signals
Output signals include the following:
Phase loss signal for use with emergency sensing
DMX512A for driving other DMX-enabled devices
Up to four racks can be slaved together to provide full control over a complete system.
1.2.1 Memory
Memory is stored in each dimmer rack that houses an SCM control module in electronic Magnetic
RAM (MRAM). This provides a full backup of the rack configuration so that SCM control modules
can be swapped out without having to worry about losing the memory. Additionally, there is a Flash
memory on each SCM control module as well as the ability to store the configuration on a removable
USB drive. Use the Rack Control Interface menus in Section 7 to access each of these memory
locations for both storing and recall. It is a good practice to save your configuration whenever you
make changes to the presets or to the configuration.
1.2.2 Ride-Thru Feature
The DX3 rack has a unique Ride-Thru feature that protects the system from momentary power outages
by holding up the power to the main processor for a minimum of 8 seconds to both reduce the reboot
time and back up the memory. This feature keeps the power applied to the main electronics via two
“super-caps” and will allow the control to reboot almost immediately (3-4 seconds) upon restoration of
main power. Upon power failure, the electronics immediately backs up the configuration to MRAM
and shuts down the SCM in an orderly fashion, much like a smart UPS will do to your computer.
DX3 relies on a power good signal to indicate if DC power is present or not, and a cap good signal
indicating that the super capacitors are fully charged. DX3 monitors the power good signal for DC
power loss. When this occurs it checks that the cap good signal indicates that the super capacitors are
charged. If cap good is valid, the backup configuration is stored to MRAM. In addition, DX3 also
places the constraint that main power must have been present for at least 10 seconds prior to dropout in
order for it to write to MRAM.

2 System Design and ayout
2.1 Typical System Riser
Figure 2 illustrates a typical system riser incorporating a theatrical console, architectural controls and
controllable fixtures. While Figure 2 illustrates a single rack at 120/208vac, multiple racks can be
linked together with some racks on 120v and some racks on 277v. This allows for a flexible system
design for multiple voltages and multiple load types.
SB2400 Dimmer Racks and SPB Power Interface Modules may also be controlled via the DMX output
from the main DX3 Rack.
Emergency transfer is available either via a UL1008 transfer switch, a Normal/Emergency dimmer rack
or Normal/Emergency SPB Modules.

2.2 Control Panel Detail
The SCM control module consists of a plug-in assembly with an integral Rack Control Interface. This
interface uses a capacitance touch keypad and data entry slider to allow simple navigation through the
menus. Control operation is described in Section 7 of this manual. Details of the features are as
follows:
•PC Communications USB Port – A USB type B port to allow connection to a computer running
the DxDirector DX3 software for use in setting up configuration, testing and control of the
system
•Graphic LCD Display – A multi-line graphic LCD display to list the menus and commands for
control of the various functions
•Status LEDS
◦DMXA or DMXB LEDS will be lit whenever these DMX ports are active
◦MODE will be lit when communication is present between the SCM and Rack Control
Interface
◦ETHERNET will blink when an Ethernet source is connected and the '10/100' LED will be
lit solid
◦STATION is not implemented
•Flash Drive Port – A USB port used for off-line storage of the rack configuration on a USB
flash drive. Multiple files can be stored, and recalled, all with unique file names
•Micro SD Card Port – A factory port used to install the operating system software

2.3 Dimmer Control Concepts
There are six ways to gain control of the dimmers and system functions as highlighted in Table 1
below. Each dimmer can be assigned to one or more of these control sources as described later in this
manual. These control sources are set up in the system configuration which is accomplished with the
PC-based program DxDirector DX3.
Table 1 Control Sources
Control Source
DMXA DMX is a serial stream of data where each piece represents a dimmer
level. DMX sources are typically from theatrical control consoles, but
can also be from other DMX-based architectural controls. DMX
sources typically provide 512 dimmers of data.
DMXB A second DMX universe for additional control
Analog Up to 24 0-10vdc analog inputs are available as an option for use with
slider type controls
Collage Built-in Collage architectural control for use with all Collage Impress
control stations. These are used for preset storage and recall of lighting
scenes across the 16 areas and 128 zones. All 512 dimmers can be
assigned to these Collage zones.
Panic There are two independent panic, or full on, functions. One or both of
these can be assigned to each of the 512 dimmers independently of
anything else that is assigned to them. The PANIC2 signal can be
activated directly on each DX3 backplane, the other can be accessed via
an optional I/O module.
Backup Cue A backup cue is a preset made up of 512 dimmer levels. The DX3 can
store 99 of these cues for recall either via the Rack Control Interface or
through remote button stations on the Collage data link.
DX3 Manual 9

2.4 Precedence
If more than one source is assigned to a dimmer, there has to be some way to define which source
actually has control at any given time. This is referred to as “precedence”. How and when a source
controls a dimmer is programmed by the “precedence selector”. Precedence selectors are used between
two sources or combinations of sources. How sources are paired up is explained in the section that
follows. There are four types of precedence selectors.
1. Highest takes precedence (HTP): This means that, for two sources, only the source that is the
highest will control that dimmer. This is also referred to as pile-on.
2. Take control if the specified DMX input is present: This type of precedence uses the detection
of a DMXA or DMXB signal input to select a source for control. When this type of precedence
selector is used for the Main or Analog/Collage selectors, it is automatically interpreted as any
DMX present whereas this selector in the DMX precedence selector column discerns between
DMXA and DMXB sources.
3. Take Control: This type of precedence uses a programmable input to select which of the two
sources controls the dimmer. There are five take controls available and they may be
programmed to respond to a switch closure, a Collage button, or a set level from any input.
4. Nothing: This precedence indicates that the control is not a combination of two sources, but
rather one source or the other or possibly neither.
