Section 1: Overview of the Displays
Daktronics GalaxyPro™ AF-3700 series displays are built to display a wide variety of messages with
great color depth. This manual provides simple installation, maintenance, and troubleshooting
information to ensure the optimal performance of the display. Diagnostic information and parts
replacement are also included. Definitions of terms and connectors used in the manual can be found
in Appendix B.
The diagrams in Figure 2 and Figure 3 give an overview of the displays. The first figure shows the
front and back views of a typical display. The second figure shows a simplified diagram of basic
display set-up.
1.1 Display Details
The GalaxyPro® model numbers are described as follows:
AF-3700-RRxCCC-34-RGB-X
AF-3700 =
RR =
CCC =
34 =
RGB =
X =
The displays are offered as single-face or double-face units. If the display is a double-face
setup, the first display is referred to as the primary and the second display is called the
mirror. If the second display will be mounted at a distance of more than six feet from the
primary display, then two primary displays will need to be utilized.
A module is the building block of the GalaxyPro
display. Each module measures 8 pixels high by 8
pixels wide (Figure 1). By placing modules side-by-side
and on top of one another, a variety of display sizes can
be designed and built. Individual modules can be easily
removed from the display if required.
A typical display system is run with a Windows
personal computer (PC) running Venus
and one or more displays. Venus 1500 is a software
package that runs under Windows 98, ME
2000, XP, or Vista Home/Professional operating
systems on an IBM
Venus 1500 operations manual (ED-13530) for
installation and operation of the Venus 1500 software.

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 weathertightness 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 hard ware.
Reference Drawing:
Shop Drawing for specific display size ......................................................... Listed in Appendix A
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. Displays 40 pixels high and larger also need unobstructed area in the back to allow for
fans expelling air through the hoods (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 (Figure 5). Display height and wind
loading are also critical factors to be considered.
This information can be found in the Shop
Drawing which was supplied with the order. These
are also listed in Appendix A.

2.2 Lifting a Display or Display Section
In order to maintain the structural integrity of the display cabinet, the 90° angle
between the cabinet and the lifting method must be maintained.
If damage occurs due to improper lifting procedures, the warranty will be void.
General Lifting Notes:
• Lift the display into position on the support structure using a lifting bar and all
eyebolts. (Figure 6).
• Do not attempt to permanently support the display by the eyebolts.
• Do not lift more than one section at a time with the eyebolts.
• Mount bottom section(s) first.
Figure 6: Correct Lifting Procedure
Figure 7: Incorrect Lifting
Left and right sections may be mounted together ONLY if a lifting bar and all eyebolts
are used. Left/right signal and ground connections may be easier to make on the ground.
Top/bottom or more than two sections should not be mounted together since the
eyebolts and connecting hardware are not strong enough for this procedure.
After installation is complete, carefully inspect the display for any holes that may allow
water to seep into the display and seal any openings with silicone.
If the eyebolts on the top of the display have been removed, plug the holes with bolts
and the rubber-sealing washer that was removed with the eyebolt unless an overhead
structure protects the area.
Refer to Section 3 for power routing and to the appropriate communication manual for
signal connections to the display.

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).
Displays are provided with unthreaded power knockouts on the back for use with 3/4”
conduit. The 8-pixel high displays have a J-box on the back for power termination.
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 lineof-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.
Power Installation 9
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.
7. Signal cable is routed to the signal termination enclosure. When required, the signal
enclosure may also be grounded.
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 di splay 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 8 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 the Power Specifications located in Appendix A. The following
sub-sections provide 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.

Power Installation
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
Installation with Ground and Neutral Conductors Provided
These displays use installation 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.
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.
Important points about grounding:
• Follow local and national codes
from region to region and from conditions present at the site. Consult the National
Electrical Code and any local electrical codes that may apply.
• Support structure cannot be used as an earth-ground electrode
generally embedded in concrete, and if embedded in earth, the steel is either primed
or it corrodes, making it a poor ground.
• One grounding electrode for each display face
configured as one grounding rod for each display face. Grounding is connected
between sections by bonding jumpers. Other grounding electrodes as described in
Article 250 of the National Electric Code may be used.
• Resistance to ground 10 ohms or less
display 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 13).
