Mechanical Installation 7
Section 3: Mechanical Installation
Mechanical installation consists of lifting and permanently mounting the scoreboard or scoreboard
sections. Be sure that the installation complies with local building codes.
Note: Daktronics does not assume any liability for any installation derived from the information
provided in this manual or installations designed and installed by others.
3.1 Lifting the Scoreboard
Daktronics Tuff Sport tennis scoreboards are shipped equipped with eyebolts for lifting the
displays, as well as pre-drilled holes along the top and bottom of each cabinet for wall
attachment. Eyebolts are located along the top of the cabinet for each scoreboard or
scoreboard section. Daktronics indoor scoreboards use 3/8" eyebolts.
Daktronics strongly recommends using a spreader bar, or lifting bar, to lift the display.
Spreader bars ensure the force on the eyebolts remains straight up, minimizing lifting stress.
Figure 4 illustrates the preferred scoreboard lifting method on the left and an acceptable
alternative lifting method on the right. When lifting the display:
Use a spreader bar if possible.
Use every lifting point provided.
Cables and chains attached to the eyebolts and directly to a center lifting point, as shown in
the right-hand example in Figure 4, can create a dangerous lateral force on the eyebolts and
may cause the eyebolts to fail. The smaller the angle between the cable and the top of the
display, the lighter the sign must be to safely lift it. If this method must be used, ensure a
minimum angle between the chain and scoreboard of at least 45°.
Do NOT attempt to lift the display if the angle is less than 45°.
Figure 4: Lifting Methods

8 Mechanical Installation
Exceeding load angles or weight limits could cause the
bolts in the scoreboard cabinet to buckle, resulting in
serious damage to the scoreboard or injury to personnel.
Also, loads should be applied directly in the plane of the
eyebolt as shown in Figure 5.
Note: Daktronics assumes no liability for damages
resulting from incorrect setup or lifting methods.
Eyebolts are intended for lifting only. Do not attempt
to permanently support the display by the eyebolts
without the suspension mounting kit (see Section 3.3).
Small Daktronics scoreboards are not equipped with
eyebolts, and instead use two lifting straps that encircle
the scoreboard. It is recommended to use a spreader bar
with the straps.
3.2 Scoreboard Mounting (Single- and Multi-Court Models)
1. Use the eyebolts at the top of the scoreboard frame
to lift the display into position for mounting.
2. Secure the display to the wall by attaching
mounting hardware through all holes on the top
and bottom rear flanges of the display to a pre-
drilled hole in the wall (Figure 6).
Note: For multi-court boards, mount the bottom
scoreboard section first, remove the eyebolts, and
mount the next section above it. Repeat until all
sections are securely in place.
Due to the variety of wall materials used in sports
facilities, Daktronics cannot anticipate a user‟s
individual installation needs or provide mounting
hardware suitable for every installation. Choose a
method of installation that will safely support the
weight of the display.
3.3 Suspension Mounting Kit (Single-Court Models Only)
One of several mounting options with the Tuff Sport scoreboards is a suspension lift eye
installation, which requires a special mounting kit (part # 0A-1237-0016). Contact Daktronics
about any installation that involves permanently suspending the scoreboard.
1. Secure the mounting angle with the 3/8" nut to each side of the scoreboard with the
included screws. Install the eyebolts into the nut on the mounting angle.
2. Attach suspension cables to the eyebolt using a shackle and pin (all of this equipment
is provided by others).
Figure 5: Eyebolt Plane Load
Figure 6: Wall Mounting

Mechanical Installation 9
Notes:
1) Daktronics recommends that two cables be used at each end of the scoreboard.
2) Cables and hardware must be specified by a licensed engineer.
3) Do not attach suspension hardware to ad panels –attach to top of scoreboard.
4) This installation method must not be used to support scoreboard with message
centers and/or backlit ad panels attached.
5) The total weight of scoreboard and accessories must not exceed 500 lb (223 kg).
Similar to the eyebolts used to lift the scoreboard, the suspension eyebolts have a maximum
angle at which they can safely support the display. The ideal angle is perpendicular to the top
of the scoreboard, but this angle may extend up to 30° out to either side of the display.
Refer to Drawing A-148644 in Appendix B for more information.
3.4 Ad Panel Mounting
Refer to Drawing A-147668 in Appendix B for typical ad panel mounting (similar to
Scoreboard Mounting shown above) or Drawing A-156134 for instructions on mounting ad
panels to the top or bottom of a scoreboard.
3.5 Scoreboard Protective Devices
Daktronics Tuff Sport displays have been designed so that a normal tennis ball impact will
not damage the LEDs or display cabinet, reducing the need for protective devices. Some
users, however, may still wish to have additional protection from other projectiles, and in
these cases, Daktronics provides optional protective devices. Refer to the Protective Screen
Installation Instructions (ED-5423), available online at www.daktronics.com/manuals for
more information about installing protective devices.
Note: Scoreboard protection devices not provided by Daktronics must be approved by
Daktronics prior to installation. Failure to follow this approval procedure will void the
scoreboard warranty.

Electrical Installation 11
Section 4: Electrical Installation
CAUTION: Only qualified individuals should access the electrical components of the display and its
associated equipment. It is the responsibility of the electrical contractor to ensure that all electrical
work meets or exceeds local and national codes.
Daktronics engineering staff must approve all changes or the warranty will be void.
4.1 Installation Overview
The diagram shown in Figure 7 illustrates a typical wireless setup between a single-court
scoreboard and the control system. Daktronics part numbers are shown in parentheses.
Drawings A-177098 and A-252412 in Appendix Dalso show power and signal layouts.

Figure 8: Wired Single-Court Installation

Electrical Installation 13
The diagram shown in Figure 9 illustrates a typical setup between a multi-court scoreboard,
optional single-court scoreboards, and a wireless or DakTennis™ control system. Daktronics
part numbers are shown in parentheses. Drawings B-231298 and B-233254 in Appendix D
also show power and signal layouts. Refer also to Drawing A-227465 for wireless RC-100
base station installation.
Note: When each court will also have its own scoreboard controlled by the DakTennis
system, the scoreboards must be set to specific driver addresses. Refer to Section 5.4 for more
information about setting driver addresses and Drawing A-1054354 in Appendix D for
addressing information.
Figure 9: Multi-Court Installation

14 Electrical Installation
4.2 Power
Each scoreboard and scoreboard section features a 120 VAC power cord with a three-prong
plug. Install a grounded receptacle near the equipment so that the power cord can easily
reach it. The control console requires a 120 VAC receptacle and uses less than 1 A of power.
Displays operating on 230 VAC are also available, and they are shipped equipped with a
universal power plug.
Grounding
Connect the scoreboard to earth ground. Proper grounding assures reliable equipment
operation and protects the equipment against damaging electrical disturbances and lightning.
Daktronics recommends a resistance-to-ground of 10 ohms or less. The electrical contractor
performing the electrical installation can verify ground resistance. Daktronics Sales and
Service personnel can also provide this service. The grounding connection on the power
cord‟s three-prong plug connects to the shell of the scoreboard.
Note: The customer must properly ground the outlet according to local and national
codes. Failure to ground the outlet voids the warranty for the scoreboard.
4.3 Power-On Self-Test (POST)
The scoreboard performs a self-test each time that power is turned on and the control console
is powered off or not attached to the scoreboard. If the control console is attached and
powered on, the self-test does not run, and data from the control console is displayed on the
scoreboard after a brief period of time. Each scoreboard self-test pattern will vary depending
on the scoreboard model, the number of drivers and types of digits. Figure 10 shows an
example of the LED bar test pattern that each digit performs.
Radio Settings
If an All Sport radio receiver is installed (see
Section 6.1), the radio broadcast settings (“b1”)
and the channel settings (“C1”) will be displayed
in the game/set score digits (Figure 11) during the
POST. These values must match the settings in the
control console (refer to the appropriate control
console manual listed in Section 1.1).
Note: Scoreboards using the RC-100 controller will only display the channel settings.
