Mechanical Installation 5
Section 2: Mechanical Installation
Mechanical installation consists of lifting and permanently mounting the scoreboard. Drawing A-
170489 in Appendix A shows the recommended number and spacing of wall anchors for scoreboard
mounting.
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.
2.1 Lifting the Scoreboard
Most Daktronics Tuff Sport scoreboards are shipped equipped with at least one eyebolt for
lifting, 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

6 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 2.3).
2.2 Scoreboard Mounting
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).
For mounting locations, weights and hardware
suggestions, refer to Drawing A-170489 in
Appendix A.
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.
2.3 Suspension Mounting Kit
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).
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).
Figure 5: Eyebolt Plane Load
Figure 6: Wall Mounting

Mechanical Installation 7
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.
2.4 Corner Mounting
Certain scoreboard models may be mounted in a corner, rather than flat against the wall,
using a special mounting bracket kit. For more information on the corner mounting option,
refer to Drawing A-150831 in Appendix B.
2.5 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 directly to the top or bottom of a scoreboard.
2.6 Scoreboard Protective Devices
Daktronics Tuff Sport displays have been designed so that a normal basketball or volleyball
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 can provide 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 9
Section 3: 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.
3.1 Installation Overview
Refer to Drawings A-124686, A-124688, A-125415, and A-125417 in Appendix A for power
and signal layouts.
Note: Control signal cable and some junction boxes are not provided as part of this
system and can be purchased locally or from Daktronics.
3.2 Power
Each scoreboard 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.
3.3 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.
Radio Settings
If a radio receiver is installed (see Section 5.3), the radio broadcast settings (“b1”) and the
channel settings (“C1”) will be displayed in the clock digits 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).

10 Electrical Installation
3.4 Scoreboard Signal Connection
Signal installation (for systems without radio control) requires routing control cable from the
scoreboard control console to a signal junction box (J-box) near the display. Refer to Drawing
A-28124 and Drawing A-125316 in Appendix A for signal wire connection.
1. At a minimum, use a paired, 22 AWG shielded cable (Daktronics part # W-1077) and
connect the cable to a dual 1/4" J-box at the control console end.
Using a dual J-box for separate Main and Auxiliary scoreboards lets operators control
several displays with one controller, and they can also switch jacks to control
individual boards using multiple controllers.
2. Route the cable from the J-box on the control console end to a J-box near the display.
3. Install the 1/4" phone plug (Daktronics part # 0L-40683) to the scoreboard end of the
cable. Be sure to connect the cable shielding only in the J-box on this end.
4. Insert the plug into the Signal In (J31) jack located on the top of the scoreboard.
5. Connect a signal cable from the J-box to the J1, J2, or J3 jack on the back of the All
Sport 5000 console.
If using a Main Clock Start/Stop Switch (0A-1166-0003), connect it to the J7 jack on
the All Sport 5000 console.

Scoreboard Troubleshooting 11
Section 4: Scoreboard Troubleshooting
IMPORTANT NOTES:
1. Disconnect power before doing any repair work on the scoreboard.
2. Allow only qualified service personnel access to internal display electronics.
3. Disconnect power when not using the scoreboard.

4.2 Component Location & Access
All Tuff Sport indoor displays are front-access scoreboards, meaning that internal electronic
components and digits are reached by opening a face panel, an access door, or a digit panel
on the front of the display.
Digit panels are typically held in place on the scoreboard face by two screws. To remove a
digit, simply unfasten the screws and carefully lift it from the cabinet. The power/signal plug
can then be removed from the connector on the back of the digit to completely free the digit
and access internal components.
Remove non-digit access panels by unfastening the top, side or bottom screws holding it in
place. Some panels are hinged and swing open when the screws are removed or loosened.
Drivers and power and signal components are typically mounted inside the scoreboard
behind a digit panel. Refer to Drawing A-170492 in Appendix A for component layouts and
access locations.
4.3 Replacing Digits
LEDs are embedded in a circuit board that is
mounted to the back of the digit panel. Do not
attempt to remove individual LEDs. In the case of a
malfunctioning LED or digit segment, replace the
entire digit circuit board.
The process of replacing digits varies by whether it
is a PanaView digit or UniView digit (Figure 7).
Figure 7: Digit Types

14 Scoreboard Troubleshooting
PanaView
To replace a PanaView digit circuit board (Figure 8):
1. Open the digit panel as described in Section 4.2.
2. Disconnect the power/signal connector from the back of the digit by squeezing
together the locking tabs and pulling the connector free.
3. Use a 9/32" nut driver to remove the nuts securing the digits to the inside of the panel,
and then lift the digit off the stud inserts.
4. Position a new digit over the studs (making sure the small plastic spacers are still in
place) and tighten the nuts.
5. Reconnect the power/signal connector.
Note: This is a keyed connector and it will attach in one way only. Do not attempt to
force the connection.
6. Secure the digit panel to the display with the two screws, then power up and test the
display to see if changing the digit has resolved the problem.
