Introduction
1-2
hNOTICE: The four-sided scoreboards covered in this manual are designed to be suspended above
players or spectators; consequently, there are serious liability considerations. It is imperative that the
roof support system be able to bear the weight of the scoreboard and all other attachments.
Therefore, the roof support system must be certified by a licensed engineer. Suspension cables and
hoist or attachment structures must also be designed and certified by a licensed engineer.
Daktronics is not responsible for structures and suspension systems designed and installed by
others.
1.2 Scoreboard Overview
The Daktronics four-sided hockey LED scoreboards are part of a family of scoreboard systems
designed to offer simple installation, easy readability and reliability. Microprocessor control assures
consistent operation and accuracy.
This manual covers the All Sport®indoor LED scoreboard displays. These models contain 7", 10" and
13" LED digits. (LEDs, or light-emitting diodes, are low-energy, high-intensity, solid-state lighting
components.) The reference drawings list dimensions and weight for each model. Scoreboard model
number and electrical requirements can be found on a label on the front of the scoreboard, typically
below the home penalty clock.
1.3 Product Safety Approval
Daktronics Indoor LED Scoreboards are ETL-listed, tested to CSA standards and CE-labeled for
indoor use. Contact Daktronics with any questions regarding the testing procedures.

Mechanical 2-1
and Electrical Installation
Section 2: Mechanical and Electrical
Installation
Following is an overview of the entire installation process. Each step is detailed in the numbered text
sections that follow. The instructions are presented in the general order in which events should occur.
1. Plan and install the hoist or static-suspension structure.
2. Provide power circuit(s) and outlet(s) at the scoreboard location.
3. Provide a power outlet at the control location.
4. Route signal cable from the control location to the scoreboard location and install the
junction box.
5. Assemble the scoreboard frame (10' models only).
6. Attach the lower ad panel supports to the frame, if required, and mount the lower ad panels.
7. Mount the scoreboard sections to the frame and join them at the top.
8. Mount the upper ad panels or message centers, if required.
9. Mount ad panels atop the message center, if required.
10. Make power and signal connections between sections.
11. Attach the corner shrouds.
12. Lift the scoreboard assembly and static-mount, or lower the hoist and attach it to the
scoreboard.
13. Make the final power and signal hookups for each tier of the display.
2.1 Four-Sided Mounting Options
The method by which the scoreboard is to be suspended must be determined at the time of purchase.
There are two primary methods of installing a center-hung scoreboard: creating a static-hung system
or using a hoist. Each method has its own benefits and drawbacks. Refer to the publication SL3710
in Appendix B and call Daktronics for help in making the best choice for your installation.
hNote: Do not attach items to the scoreboard without prior approval. To properly review and
approve a proposed attachment, Daktronics requires information on the size, weight and method by
which the item will be attached to the scoreboard. (Engineering time to review attachments will be
charged out at a “time and expenses” rate.)
Static Mounting Systems
Static-mounted displays are typically hung with two or four static cables. Two cables may be
used when mounting the scoreboard below a large beam or centered between a pair of beams.
Four cables are used to further distribute weight. For either method, the mount cables must be
symmetrically distributed to maintain a level and a square configuration.
Cable assemblies must have a nominal strength greater than six times the actual load. All other
rigging components must be sized within the working load limits published by the component
manufacturer.
hNote: Daktronics strongly recommends that only components from reputable domestic
suppliers be used to permanently suspend the scoreboard.

2-2 Mechanical
and Electrical Installation
Remove immediately and do not use an assembly that shows evidence of excessive wear or
broken wires as defined by the component manufacturer.
1. Have a structural engineer certify that the building can safely support the additional
display loading and that the connection points are designed to safely carry the
scoreboard weight.
2. Attach the cable sling to the scoreboard while it is on the arena floor.
3. Hang the ends that attach to the ceiling over the sides of the scoreboard. If an end is too
short, attach a rope to the end so it can be returned from the top.
4. The scoreboard can be lifted into place many different ways.
hNote: It is the installer's responsibility to ensure that the installation is safe and that
the display meets OSHA or local regulations.
Lifting Method Example: A common method of temporarily lifting the scoreboard is to use a
pair of chain-lift motors mounted on the ceiling. Prior approval should be secured from the
facility management regarding location and acceptable loads for each rigging point.
1. Attach the chain hoist hooks to the sling master link or sling to the corner eyebolts. Be
sure the angle of the sling is greater than 45 degrees.
2. Use the chain hoist to lift the scoreboard to the appropriate height.
3. From the lift, retrieve the sling cables draped over the sides of the scoreboard and attach
them to the appropriate locations in the ceiling.
4. Hook up power and signal to outlets and junction boxes in the ceiling.
5. Level the scoreboard by adjusting the turn bracket on the sling.
6. Lower the weight of the display onto the slings.
7. Remove the chain motors.
Electric Hoist Systems
Installing an electric hoist system is more complex and may expose the customer to greater
liability. SL-3610 (found in Appendix B) discusses recommended minimum hoist specifications
and points that must be considered when selecting a hoist system.
 A building engineer must review and approve the combined weight of the scoreboard,
hoist and a minimum impact factor of 15 percent.
 The hoist must be accessible for periodic inspections and maintenance as required by
ANSI and OSHA. hNote: Records of period inspections must be on file to be
accessible for OSHA (see Section 3.1 of this manual).
 Electrical service and control wiring must be run to the hoist location.
 Additional structures are often required in the ceiling to accommodate the hoist.
 If an existing hoist is to be used, or if a hoist is to be purchased directly by the end user,
the user assumes all responsibility and liability for the hoist system.
 The hoist must be inspected and certified in writing by the hoist manufacturer,
manufacturer's representative or other qualified hoist inspector.
 Daktronics will inspect hoists installed by Daktronics.
 Daktronics will certify the scoreboard weight but will require a liability waiver signed by
the customer before the scoreboard is shipped.
Once the hoist is installed according to the specifications of the hoist manufacturer and the
building engineer:
1. Lower the hoist hooks to the scoreboard.

Mechanical 2-3
and Electrical Installation
2. Hook the master links to the hook blocks, ensuring that the hook safety latches are
closed and operating correctly.
3. Raise the scoreboard 1' to 2' and level it by adjusting the sling turnbuckles.
4. The hoist installer must set upper and lower primary limits and all safety limits.
Daktronics recommends maintaining a minimum distance of 2' between the scoreboard
and the nearest obstruction.
WARNING:
•=Never ride in or work on or below the scoreboard while the hoist is powered up.
Daktronics recommends having an audible horn warning to indicate that the hoist
system is on.
•=Never operate the hoist system during public events or when there are people below
the scoreboard.
•=When using the hoist the operator must have an unobstructed view from ceiling to
floor (to ensure free scoreboard travel). Hoist operators should be trained according to
the hoist manufacturer's specifications.

hPlease review the following section completely before beginning assembly.
10' Frame Assembly
Reference Drawing:
Frame Assembly; 4-Sided........................................................Drawing A-107157
The 10' frame is shipped as two 5' x 10' sections (refer to Drawing A-107157). Note that each
section has two corners with a brace across the corner and two corners without a brace. The
eyebolts in the braced corners will be on the top side. The optional sheet metal floor is attached
to the top side of the frame sections at the factory.
1. Lay out the two sections with the unbraced sides together.
2. Join the sections along their common side, using two 3/8-16 x 1" bolts toward the
middle, and 3/8-16 x 1-1/2" bolts at the corners.
3. Join the two sections at the ends with the splice plates and bolts.
4. Use 1-1/2" bolts where the bolt must pass through the reinforcing angles in the corners.
Attaching Optional Lower Ad Panels
Reference Drawing:
Bottom 4-Side Ad Panel Mounting................................................. Drawing A-107664
This step is required only if the scoreboard has ad panels or auxiliary scoreboard displays
attached to the bottom. Refer to Drawing A-107664. Support brackets are attached to the bottom
of the frame, and the ad panel sections are to be attached to these brackets. The support brackets
are designed to be able to support the weight of the whole scoreboard after it is assembled on the
arena floor. The bottom ends of the supports should extend about 1/16" beyond the bottom of the
lower ad panels so that the scoreboard’s weight is not resting on the ad panels.
1. Raise the frame and support it on blocks or stands.
2. Locate the four holes near each corner of the frame on the bottom side.
3. Insert the 3/8" bolts through the frame holes and secure the support brackets to the
bottom of the frame with washers and nuts.
4. Repeat for all four corners.
5. Attach the ad panels to the support brackets with3/8" bolts, washers, and nuts.

Mechanical 2-5
and Electrical Installation
4. Join the two sections at their common top corner using a top bracket with ‚lbolts,
washers and nuts as shown in Detail A on Drawing A-107887. Once the two sections
are joined, they will not require additional support during assembly.
5. Repeat for the third and the fourth sections, attaching each to the frame at the bottom and
to the other sections at the top corners.
Mounting an Optional Top Ad Panel or Message Center
Reference Drawing:
Top; 4-Side Ad Panel Mounting................................................Drawing A-107665
Drawing A-107665 illustrates the parts used in this procedure. The ad panels or the message
centers are attached to the top of the scoreboard with mounting strips and then joined at the top
with special brackets.
1. Attach the mounting strips to the top of the scoreboard. The mounting strips are fitted
with 1/4-20" threaded inserts.
Position a mounting strip inside the top channel of the scoreboard section, aligned with the
holes in the back.
Insert a tapered washer between the mounting strip and the scoreboard and attach with a bolt.
The tapered washers allow the ad panel or message center to be supported in a vertical
position while the scoreboard tilts out 10 degrees.
Leave the bolts a little loose until the ad panel or message center is in place. Each scoreboard
section and ad panel or message board requires two mounting strips.
1. Lift one ad panel or message board section into place atop the scoreboard section. Align
the holes along the back bottom of the display with the threaded inserts in the mounting
strips.
2. Install and tighten the 1/4" bolts. Support the ad panel or message center section to
prevent it from tipping while a second section is positioned and secured.
3. Join the tops of the two sections with a top bracket and 3/8" bolts, washers and nuts.
Once the two sections are joined at the top, they will not require additional support
during assembly.
4. Repeat for the third and the fourth sections, mounting the bottoms to the mounting strips
on the top of the scoreboard and joining the tops to the other sections with the top
brackets and 3/8" hardware.
Mounting Optional Ad Panel on the Message Center
Repeat the mounting procedures in preceding subsection. Tapered washers are not required. The
message centers and the ad panels are both vertical and do not require the alignment angle
change provided by tapered washers.
Connecting Power and Signal Between Sections
Reference Drawing:
Ad Panel, Message Cntr Hookup.............................................Drawing A-109746
Connect the power cords from one backlit ad panel or message board section to the next as
shown in Drawing A-109746. Ad panel and message center power and signal connectors are
located on the ends of the sections. Inputs are on the left end (as viewed from the front) and
outputs are on the right end. Scoreboard power and signal connectors are in the back of the
scoreboard sections.

2-6 Mechanical
and Electrical Installation
To connect the power and signal:
1. Connect the signal cables provided to the jacks in the back, matching the input and
output numbers as labeled. Message board signal connections use the six-position plugs
provided with the displays. Connect as shown in Drawing A-109746.
2. Connect the power cord from one section to the receptacle on the next. The first section
in each row is to be connected to a power outlet previously installed for this purpose, and
signal wire is to be routed to a box at the control location.
3. The last section in each row has nothing connected to its output jacks. Actual power and
signal connections will wait until the scoreboard assembly is suspended.
h
hh
hNote: If a hoist is used, power and signal cables must be long enough to allow the scoreboard
to be lowered. The optional sheet metal floor will contain the cables when the scoreboard is
raised. If the scoreboard is static-mounted, the cables need only to be long enough to provide
service. Excess lengths should be neatly tied out of the way.
Attaching Corner Shrouds
Corner shrouds are metal panels that cover the outside corners of the four-sided assembly.
Separate shrouds are provided for each tier of the assembly.
1. Position each corner shroud across the appropriate corner and mark the locations of the
holes on the scoreboard, ad panel or message center.
2. Drill 9/64l(3.5mm) holes as guide holes for the screws.
3. Secure the corner shrouds to the corners with the #8 tapping screws provided.
4. Leave one corner of the scoreboard open to allow access until the whole assembly is
ready to be suspended.
Attaching Suspension Cables
The roof of the facility and any structures fabricated for the purpose of suspending the
scoreboard, as well as the suspension cable slings, must be designed by or inspected and
approved by a qualified engineer.
If the scoreboard is to be static-hung (suspended from fixed cables without a hoist):
1. Attach the cables to the four 5/8" eyebolts at the corners of the frame. The cables may be
joined together to make two attachment points, or all four cables may attach directly to
the roof trusses or the mounting structure. Eyebolts must be aligned with cable to
prevent side pull.
2. Hang the top ends of the cables over the sides of the scoreboard to get them out of the
way and to make them accessible when hooking up.
3. Lift the scoreboard using an appropriate means, such as a chain hoist, to the correct
suspension height.
4. Attach the top ends of the cables to the previously prepared mounting points.
5. Remove the temporary lifting apparatus and level the scoreboard by adjusting the
turnbuckles built into the slings.

Mechanical 2-7
and Electrical Installation
If the scoreboard is to be suspended from a hoist:
1. Start by attaching the cable sling to the four eyebolts in the corners of the frame.
2. Lower the hoist cables and attach them to the cable slings.
3. Raise the scoreboard a foot or two from the floor and level the scoreboard by adjusting
the turnbuckles built into the slings.

1. Install a grounded receptacle near the display so that it is accessible to plug in the power
cord. Each scoreboard is equipped with a 120V AC, three-prong plug for power in and
power out.
2. Determine which section is the closest to the grounded 120V AC receptacle. Connect the
power cord that is on the right side (when viewed from the rear) of the section and plug it
into the left side of the next section.
3. Continue to connect each section to the next until all the sections are connected.
4. Connect the remaining power cord to the grounded 120V AC receptacle.
2.4 Grounding
The circuit outlets must contain connections to earth-ground. Proper grounding assures reliable and
safe equipment operation. Proper grounding will also protect the equipment from damaging electrical
disturbances and lightning. The grounding connection on the three-prong plug power cord connects
to the shell of the scoreboard.

diagrams for the scoreboard models covered in this manual.
hNote: Disconnect power before servicing the display! Disconnect the power, too, when the
display is not in use. Leaving the power on when the display is not in use decreases the life of some
electronic components.
3.6 Adjusting Horn Volume
Horn volume is set at its maximum level at the factory. If the horn is too loud, reduce its volume by
adjusting the setscrew mounted in the front of the horn. A plastic tip on the screw touches the horn's
diaphragm, reducing the volume. Turn the screw clockwise and test the volume by operating the horn
from the scoreboard control console. Continue adjusting and testing until the desired volume level is
obtained.
Four-sided scoreboards have a horn in each of the four sides (faces).
If the standard electronic horn is not loud enough for your facility, a trumpet horn can provide
significantly greater volume. On a four-sided scoreboard, a single trumpet horn may be mounted
behind one of the scoreboard faces, pointing down at the playing area. Contact Daktronics for more
information and pricing.
hCaution! The horn is a 120V AC device. Turn off the power to the scoreboard before adjusting the
horn!
3.7 Troubleshooting
Daktronics scoreboards are built for long life and require little maintenance. However, from time to
time, a display may malfunction, and certain components will require replacement. The replacement
parts list in Section 3.8 includes part numbers of components it may be necessary to reorder. Most
display components also have a white label that lists the part number. Finally, refer to the drawings in
this manual to obtain the correct replacement part number for any damaged component.
For assistance with troubleshooting and to order replacement components, first contact your service
provider. The service provider may have spare equipment on hand and, in the event of an emergency,
may offer same-day service. Call the Daktronics Help Desk – [phone] if directed by your
service technician or if no service provider is available.
For faster service, note the model of the scoreboard and any problem-area assembly numbers, as
shown on the scoreboard spec sheet. If replacement components will be required, have a purchase
order number or any other purchase information in hand when calling.

3.9 Warranty and Maintenance Program
Daktronics recommends that each customer keep an inventory of essential parts in case problems
arise. If equipment fails, the customer's local service technician can get the equipment operational
again with spare parts kept on hand. The failed components can then be shipped to Daktronics for
parts exchange.
To provide parts quickly, Daktronics introduced a parts exchange program more than 20 years ago.
The program offers a fast and economical way to replenish the customer's spare parts inventory if a
component fails; it saves money and reduces downtime. Under normal circumstances, Daktronics
sends a reconditioned replacement part within a 24-hour period. In urgent situations, Daktronics ships
using the fastest method available.
]Under the warranty and maintenance program, the customer must send all failed components within
15 days of receiving the exchange components from Daktronics. If the parts have not been received by
Daktronics within 30 days, the customer will be billed for the replacements at full price.
For assistance, contact the Daktronics Help Desk at [phone]. A Daktronics technician is on-
call from Friday evening until Monday morning. A special call-diverting system notifies the on-call
technician during the weekend. The call-diverting system asks the customer to leave a message and
telephone number, including area code, for the technician to call back. In emergency situations,
Daktronics makes every effort to ship replacement equipment immediately. Daktronics leads the
industry with this unique weekend service.
For specific information on your Daktronics scoreboard, refer to the warranty in the original purchase
packet shipped with the scoreboard. Unless specifically stated in the warranty agreement, the warranty
does not cover on-site labor.

3.10 Daktronics Exchange/Repair and Return Programs
To serve customers’ repair and maintenance needs, Daktronics offers both an exchange program and a
repair and return program.
Daktronics' unique exchange program is a quick, economical service for replacing key components in
need of repair. If a component fails, Daktronics sends the customer a replacement, and the customer,
in turn, sends the failed component to Daktronics. This not only saves money but decreases
scoreboard downtime. This service is provided to qualified customers who follow the program
guidelines explained below.
Daktronics provides this service to ensure users get the most from their Daktronics products. Please
call the Help Desk – [phone] – if you have questions regarding the exchange program or any
other Daktronics service.
When you call the Daktronics Help Desk, a trained service technician will work with you to solve the
equipment problem. You will work together to diagnose the problem and determine which exchange
replacement part to ship. If, after you make the exchange, the equipment still causes problems, please
contact our Help Desk immediately.
If the replacement part fixes the problem, package the defective part in the same box and wrapping in
which the replacement part arrived, fill out and attach the enclosed UPS shipping document, and
RETURN THE PART TO DAKTRONICS. In most circumstances, you will be invoiced for the
replacement part at the time it is shipped. This bill is due when you receive it.
Daktronics expects immediate return of an exchange part if it does not solve the problem. The
company also reserves the right to refuse equipment that has been damaged due to acts of nature or
causes other than normal wear and tear.
If the defective equipment is not shipped to Daktronics within 30 working days from the invoice date,
it is assumed you are purchasing the replacement part, and you will be invoiced for it. This second
invoice represents the difference between the exchange price and the full purchase price of the
equipment. The balance is due when you receive the second invoice. If you return the exchange
equipment after 30 working days from the invoice date, you will be credited for the amount on the
second invoice, minus a restocking fee.
]To avoid a restocking charge, please return the defective equipment within 30 days from the
invoice date.
Daktronics also offers a Repair and Return program for items not subject to exchange.
Return Materials Authorization: To return parts for service, contact your local representative prior
to shipment to acquire a Return Material Authorization (RMA) number. If you have no local
representative, call the Daktronics Help Desk for the RMA. This expedites repair of your component
when it arrives at Daktronics.
Packaging for Return: Package and pad the item well so that it will not be damaged in shipment.
Electronic components such as printed circuit boards should be installed in an enclosure or placed in
an antistatic bag before boxing. (Antistatic foam packaging and circuit-board shipping boxes are
available from Daktronics). Please enclose your name, address, phone number and a clear description
of symptoms.
