Section 2: Mechanical Installation
Read the Mechanical, Power and Signal Installation sections before installing the display(s).
Daktronics engineering staff must approve any changes that may affect the weather-tightness of the
display. If any modifications are made, detailed drawings of the changes must be submitted to
Daktronics for evaluation and approval, or the warranty may be void.
Daktronics is not responsible for installations or the structural integrity of support structures done
by others. The customer is responsible for ensuring that a qualified structural engineer approves the
structure and any additional hardware.
2.1 Support Structure Requirements
The installer is responsible for ensuring that the mounting structure and hardware are
capable of supporting the display, and that the structure follows all local codes.
Support structure design depends on the mounting methods, display size, and weight.
Because every installation site is unique, no single procedure is approved by Daktronics for
mounting GalaxyPro
information only and may or may not be appropriate for this particular installation. Refer to
Figure 2 and Figure 3 for basic display set-ups.
Mounting plans need to take into account the ventilation system for the specific display size.
In general, the front of all displays needs to be unobstructed to allow for air flow and internal
access. Small displays contain fans on the bottom that pull air in from the lower vent and
exhaust it out the top vent. Displays 64 pixels high and larger need unobstructed area in the
back to allow for fans expelling air through the hoods as shown in Figure 4.
Also keep in mind the location of the mounting clips
and the clearance needed for the power/signal
terminations on the back of the display as shown in
Figure 5. Display height and wind loading are also
critical factors to be considered. This information can
be found in the Shop Drawings in Appendix A. Be
sure to consult the drawing for the appropriate pixel
matrix size.

The display is in good condition after shipping and uncrating.
•
•
A straight and square-mounting frame is provided for the display.
Height variation in any four-foot horizontal section may not exceed ¼-inch.
•
Adequate support is provided for the display so that the structure will not yield at
any unsupported points after mounting.
• Clearance of 4" of unobstructed space above the top of the display is allowed to
remove the eyebolt. Note: No clearance is required once the eyebolt is removed.
•
Clearance around the display is maintained to allow unobstructed air flow through
the vents and fans and to allow access to internal components.
2.2 Display Mounting
In order to maintain the structural integrity of the display cabinet, the 90° angle between the
cabinet and the lifting method must be maintained.
Do not lift combined sections by the eyebolts.
The eyebolts and interconnect bolts are not strong
enough to support the weight of multiple sections.
If damage occurs because of improper lifting
procedures, the warranty will be void.

Mechanical Installation 7
Page 18
Page 19
Read the Mechanical, Power, and Signal Installation sections before installing the
display(s).
Only a qualified individual should terminate power and signal cable at this Daktronics
display.
All proposed changes must be approved by Daktronics engineering staff or the warranty will
be rendered null and void.
3.1 Conduit
Daktronics does not include the conduit. Separate conduit must be used to route:
• Power.
• signal IN wires to the signal termination enclosure, when applicable.
• signal OUT wires (if not using the provided interconnect cable).
Most displays are provided with unthreaded knockouts on the back for use with ½” conduit.
The 16 pixel high displays have a J-box on the back for power termination.
Section 3: Power Installation
3.2 Overview of Power/ Signal Connection
Following is a brief summary of the power and signal connections to the display.
1. Power to the display will be terminated internally in most cases. Section 3.5 shows
the internal wiring diagrams.
2. Possible methods for signal termination are shown in the manual for the specific
communication type.
3. Power is routed to the display through a fused disconnect switch capable of opening
all ungrounded power conductors. Install this disconnect within the line-of-sight of
any personnel performing maintenance on the display. (If the disconnect is located
out of sight of the display, it must be capable of being locked in the open position.)
Note: Displays are equipped with overcurrent protection devices that carry a UL489 or
UL1077 (IEC 60947, VDE 660) rating. These devices are only intended to protect the
components within the display. Suitable devices must be used for the equipment and feeders
supplying power to the display.
4. Power conductors from the disconnect to the display should be routed through
conduit in agreement with local code.
5. Display power will terminate internally at the power termination panel.
6. Connect the grounding electrode conductor at the grounding lug on the back of the
display. With sectional displays, connect one grounding lug to earth ground and run
the bonding jumper between display sections.
Power Installation 9
Page 20
7. Signal cable is routed to the signal termination enclosure. When a ground cable is
provided with the enclosure, ground the enclosure to an isolated earth ground
connector.
8. Signal into the enclosures must be routed through conduit. The knockouts in the
enclosures require the use of ½" conduit.
9. The signal quick-connect cable from the enclosure to the display can be routed
through conduit or through the display pole if power is not also routed in the display
pole.
Note: Daktronics strongly recommends that the quick-connect cable be secured to protect it
from weather or vandalism.
3.3 Power Requirements
Do not connect the displays to any voltage other than that listed on the Daktronics product
label.
Important Note: Conductors of circuits delivering power to a Daktronics display shall be
sized in accordance with NEC and local electrical codes so that the power distribution system
is capable of delivering full load power to the display while maintaining a voltage within 5%
of the utility nominal voltage.
Each display size may be constructed to use either single-phase or three-phase power, with
the exception of the 16 high displays which use only single-phase power. Proper power
installation is imperative for proper display operation. Power specifications for various size
displays can be found in Appendix A. The following sub-sections provide general details of
power installation.
Main Disconnect
The National Electrical Code requires the use of a lockable power disconnect near the
display. Provide a lockable disconnect switch (knife switch) at the display location so that all
power lines can be completely disconnected. Use a disconnect so that all hot lines and the
neutral can be disconnected. The main disconnect should be mounted at or near the point of
power connection. A main disconnect is to be provided for each supply circuit to the display.
The disconnecting means must be located in a direct line of sight from the display or outline
lighting that it controls. This requirement enables a worker to keep the disconnecting means
within view while working on the display.
Exception: Disconnect components that are capable of being locked in the open position may
be located elsewhere.

3.4 Grounding
This sign is to be installed in accordance with the requirements of Article 600 of the National
Electrical Code and/or other applicable local codes. This includes proper grounding and
bonding of the sign.
Displays must be grounded according to the provisions outlined in Article 250 of the
National Electrical Code
These displays are installed with ground and neutral conductors provided. The power cable
must contain an isolated earth-ground conductor.
Under this circumstance, do not connect neutral to ground at the disconnect or at the display.
This would violate electrical codes and void the warranty. Use a disconnect so that all hot
lines and neutral can be disconnected. The National Electrical Code requires the use of a
lockable disconnect if the disconnect is not located within sight of the display.
The display system must be connected to earth-ground as shown in Figure 14. Proper
grounding is necessary for reliable equipment operation. It also protects the equipment from
damaging electrical disturbances and lightning. Daktronics requires a resistance to ground of
10 ohms or less. The display must be properly grounded or the warranty will be void.
®
.
Figure 14: Correct Grounding of Display
Important points about grounding:
• Resistance to ground 10 ohms or less
performance. If the resistance to ground is higher than 10 ohms, it will be necessary to
install additional grounding electrodes to reduce the resistance. The grounding
electrode should be installed within 25 feet of the base of the display. The grounding
electrode must be connected to the ground lug on the back of the display (Figure 14).
• Follow local and national codes
region to region and from conditions present at the site. Consult the National Electrical
Code and any local electrical codes that may apply.
Power Installation 11
: This is required by Daktronics for proper display
: The material of an earth-ground electrode differs from
Page 22
• Support structure cannot be used as an earth-ground electrode
: The support is
generally embedded in concrete, and if in earth, the steel is either primed or it corrodes,
making it a poor ground.
• One grounding electrode for each display face
: The grounding electrode is typically one
grounding rod for each display face. Other grounding electrodes as described in Article
250 of the National Electric Code may be used.
Note: Each section of a sectional display has a ground lug but only one lug per display
face needs to be connected to the ground rod. A bonding jumper runs between sections.
Grounding Sectional Displays
In addition to following all the requirements of general
grounding, sectional displays have a few additional
requirements.
Each section of a sectional display will contain a ground
lug. Only one of these lugs needs to be connected to
earth ground. Refer to Figure 15.
A bonding jumper is present in the top section. Connect
this to the bottom section by unscrewing the nut,
placing the loop end of the cable over the screw, and
replacing the nut. Refer to Figure 16.

3.6 Power Routing in the Display
Following is a basic overview of power routing. Check exact power routing for a specific
display on the Layout Drawing found in Appendix A.
A general power routing, as shown in Figure 25, can be summarized as follows.
1. Power terminates internally to the power termination panel.
2. Power travels through the transformer which adjusts power to the appropriate voltage
for the controller.
3. Power is routed through filters to the power supplies which provide power to the
modules.
4. Power is also sent from the last breaker on the power termination panel through a filter
to the fans and the thermostat.
Note: Power supplies are preset to the proper voltage: 12-13.1VDC.

6.2 Ventilation System/ Fans
Frequency of Inspection
In displays smaller than 64 pixels high, ventilation fans are located
along the bottom of the display. The fans pull air into the cabinet
from the lower vent, exhausting air out the top vent (Figure 39).
Displays 64 pixels high and larger have fans mounted on the back of
the display, pulling air from the front vents and out through hoods
(Figure 40). Sectional displays have fans in both top and bottom
sections. Air is pulled in either top or bottom vent and out the back.
Fans should be checked every time the display is opened or at a
minimum of once per year. Check more often if the display is located
in a dusty or harsh environment, such as along a gravel road.
Fan Blades
Check the fan blades for dirt and debris, cleaning them and the
inside of the display if necessary. Fan blades must be kept clean to
maintain fan efficiency and to ensure proper cooling. Spin the fan
blades with a pen or pencil to ensure that the bearings are free and
that the fan is still in balance.

back. Release ribbon cables by spreading the
tabs on the sides and then lifting the cable head
from the jack (Figure 49).
4. Unplug the power cable by squeezing the tabs
on the sides of the plug head and pulling out.
5. Connect all three cables to the new module,
making sure that the ribbon cable tabs are
tightly pushed against the cable head. Carefully
push the ribbon wires back into the cabinet so
they are clear of the module edges.
6. Place the module into its proper location,
checking that the weather stripping is in place.
Latch the module tightly both top and bottom
by turning the hex wrench a quarter turn
clockwise.
Note:
• The weather-stripping on the back edge of the module must be in good condition and
returned to its proper position if it is to prevent water from seeping into the display.
• The module latches must be fully engaged to
create a watertight seal around the edge of the
module. The module should be firmly seated
against the display when the latches are fully
engaged.

Controller Address Setting
The rotary switches set the hardware address which the
software uses to identify that particular display. Each controller
in a network needs a unique address.
To set the rotary address switches, rotate them until the arrow
points to the desired number. The display's power must be
turned off and then turned back on to activate the test mode or
to change an address.
Note:
• Setting both rotary switches to address 0 will activate Test
Mode. Turn the display's power off and back on to activate
testing.
• After testing, reset the rotary switches to an address other
than 0/0. The software will not recognize an address of 0.

Memory Storage Card
Do not remove the memory storage card with power connected to the controller –
critical damage will result.
The controller in the GalaxyPro display contains a 2 GB memory storage card. This card
stores the configurations, messages, schedules and fonts created by the control software. The
memory storage card can be moved if a controller needs to be replaced or if the information
stored on it needs to be used on another display. The information on the card will
automatically be recognized and available for use by the display, thus eliminating the need to
reconfigure a display.
To remove the memory storage card, disconnect power and then gently push in on the edge
of the card. The card will spring out of its location on the controller.
To install a memory storage card, slide it into the slot on the side of the controller. Push it
gently in until a click is felt. The card should now be held firmly in the slot.
Warning! The memory storage card is specifically designed to work with the GalaxyPro
controller. Do not attempt to reprogram or move files by inserting this card in a computer or
other device. The card will then no longer function correctly in the controller.

Definitions of Terms
Controller: The “brains” of the display. The controller receives signal communication from the
computer and sends the appropriate information to the modules. Messages and schedules may also
be stored on the controller for use when desired.
Display Address: An identification number assigned to each display of a network. The control
software uses the address to locate and communicate with each display. Displays that are on the
same network must have different addresses.
Driver/LED Board: The LEDs are mounted directly onto the module. This board is also responsible
for the on/off and intensity levels of the LEDs.
GalaxyPro
LED (light emitting diode): A low energy, high intensity lighting unit.
Louver: Black plastic ledge positioned horizontally above each pixel row. The louvers block sunlight,
thus increasing the level of contrast on the display face.
Mirror: The second display in a two-sided configuration. The mirror display does not have a
controller so it displays an exact copy of the information on the primary display. All signal
information to the mirror is received through an inter-connect cable from the primary display.
Module: 20 mm GalaxyPro
removable from the front of the display.
Network: Consists of multiple displays connected to each other. As many as 240 primary displays
can exist on one network.
Pixel: A single LED or cluster of LEDs. The number and color of the LEDs will depend on display
application.
Primary: A single-faced unit or the first display in a Primary-Mirror (2V) configuration. The
communication signal, light sensor and temperature sensor will be connected to this display. The
information from these components will be relayed from the primary display to the mirror display so
that it shows exactly the same information. An inter-connect cable will transfer this information from
the primary to the mirror display in this configuration.

Common Power and Signal Connectors
When pulling a connector plug from a jack, do not pull on the wire or
cable; pull on the plug head itself. Pulling on the wires may damage the
connector.
The power and communication signal connections in the displays use many
different types of connectors. The following information presents some common
connectors encountered during display installation and maintenance:
Ribbon Cable Connectors:
A typical ribbon connector is shown in Figure 58. To disconnect the
ribbon cable, push out the plastic clips on the sides to unlock the cable
and then remove the jack.
Before replacing a ribbon cable connector, spray it with DeoxIT
cleaner to remove any foreign matter that may cause signal problems. In
addition, apply a generous amount of CaiLube
™
protector paste to the plug
before inserting it into the jack. This paste will protect both the plug and the
jack from corrosion.
Termination Blocks:
Termination blocks are commonly used to connect internal power to an
external power source. Power wires need to have one-half inch of insulation
stripped from the end of the wire prior to termination. Insert wires into
terminations and make sure the clamp holds the wire firmly. A typical
termination block is shown in Figure 59.
Phoenix
™
-Style Connectors:
Phoenix-style connectors, which are usually green, are often used for
communication signal termination on circuit boards. Refer to Figure 60.
Strip one-quarter inch of insulation from the wire prior to insertion. To
remove a wire, turn the corresponding screw counter-clockwise to loosen
the connector's grip on the wire. To insert a wire, push the bare wire into
the connector and turn the above screw clockwise to lock the wire into
place.
®
Mate-n-Lok
Connectors:
The Mate-n-Lok connectors found in the displays are white and come in a
variety of sizes. Figure 61 illustrates a four-pin Mate-n-Lok connector. To
remove the plug from the jack, squeeze the plastic locking clasps on the side
of the plug and pull it from the jack.

Glossary
Page 78
Phone/Network Jacks (RJ11/RJ45 Connectors):
RJ connectors, as seen in Figure 62, are similar to the telephone connectors or network jacks
found in homes and businesses. These jacks are used on the ends of RJ11 or RJ45 cable. In
order to remove this plug from the jack, depress the small clip on the underside of the plug.
Before replacing an RJ connector, spray it with DeoxIT
foreign matter that may cause signal problems. In addition, apply a generous amount of
CaiLube
™
protector paste to the plug before inserting it into the jack. This paste will protect
both the plug and the jack from corrosion.
Quick-connect Jack:
The display uses quick-connect jacks for the connection of the signal, the temperature sensor
and the connection to a mirror display. Three input and one output quick-connect jacks are
located on the back of the primary display. When not in use, the
attached dust cover should be kept closed.
To attach the cable to a jack, match the configuration of wires in the
plug to the pattern in the jack. Push the plug in, then turn the outer
collar to lock it into place. Figure 63 illustrates the six-pin quickconnect jack.
Fiber Optic Cable:
A fiber optic network transmits light (signal) through a glass fiber.
Because fiber optic cable is glass, the cable must never be bent. The
cable is usually a four-fiber cable, with two fibers used for display
communications and the other two saved for spares. A four-fiber cable
is shown in Figure 64.

1.1 Temperature Sensor Overview
The temperature sensor enclosure, shown in Figure 1, is
composed of eight plastic disks, a metal mounting bracket,
and a 25-foot weather-resistant cable.
In most cases, the enclosure is mounted using two screws.
The cable is plugged into the back of the display.
It may be necessary to disassemble the enclosure or rewire
the temperature sensor board. Instructions are provided for
those situations.
Refer to the following chart for part numbers if replacement
or additional parts are needed.
Temperature Sensor
1.2 Mounting Locations
For greater temperature accuracy, follow these mounting
recommendations:
• Mount sensor vertically.
• An ideal location is under a north eave or on a
northern exposure away from direct sunlight, as
shown in Figure 2. In these cases, the quick-
connect cable is not used. Four-conductor, 22AWG, shielded cable must be pulled from the
display to the temperature sensor location. Route
the cable through conduit when exposed to
outdoor conditions. The maximum length of the
cable should be no more than 500 feet.
• Mount the sensor above grass or vegetation
rather than concrete or other pavement.
• Mount at least 20 feet away from chimneys,
vents, air conditioners, or other items that would
influence correct temperature readings.
• Do not mount the sensor between displays or locations that restrict air movement.
• Mount the sensor so the cable is protected from weather and vandalism.
