Daktronics Tuff Sport scoreboards are ETL-listed, tested to CSA standards and CE-labeled for
indoor use. Contact Daktronics with any questions regarding the testing procedures.

Note: The four-sided scoreboards detailed in this manual are designed to be suspended
above players or spectators, and that creates serious liability considerations. It is
imperative that the roof support system be able to bear the weight of the scoreboard and
all other attachments. Consequently, a licensed engineer must certify the roof support
system. 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 or installed
by others.

6 Specifications

Section 3: Mechanical Installation

Mechanical installation consists of lifting and permanently mounting the scoreboard and any optional
advertising panels or message centers. The mechanical specification drawings listed in Appendix A
show measurements, cable attachment points, and mounting weights for each scoreboard model.

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.

Below is a general overview of the entire installation process. Each step is detailed in the sections that
follow, and 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 (if the system is not controlled by radio).

5. Assemble the scoreboard frame.

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. Route and connect all power cords and signal cables around the top of the scoreboard.

9. Mount the upper ad panels or message centers, if required.

10. Mount ad panels atop the message center, if required.

11. Make power and signal connections between message center sections and/or power

connections for backlit ad panels, if required.

12. Attach the corner shrouds.

13. Lift the scoreboard assembly and static-mount, or lower the hoist and attach it to the

scoreboard assembly.

14. Make the final power and signal hookup to each tier of the display (scoreboard tier,

backlit ad panel tier, message center tier).

3.1 Lifting the Scoreboard

Daktronics Tuff Sport scoreboards are shipped equipped with a single eyebolt for lifting the
display into place. The eyebolt is located in the center of the top of the scoreboard cabinet.
Daktronics indoor scoreboards use 3/8" eyebolts. Use the single eyebolt at the top of the
scoreboard section only to lift the display into position for assembly.

Note: Eyebolts are intended for lifting only. Do not attempt to permanently support the
display by its eyebolt. Daktronics assumes no liability for damages resulting from
incorrect setup or lifting methods.

Mechanical Installation 7

3.2 Four-Sided Scoreboard Suspension 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 suspension publication, DD1627665, in Appendix F, and call Daktronics for help in
making the best choice for your installation.

Note: 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 at a "time and expenses" rate.)

Static Mounting

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 when the display is centered
between a pair of beams. Four cables are used to further distribute weight.

Note: For either method, the mounting cables must be symmetrically distributed to
maintain a level and a square configuration.

Cable assemblies must have a 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.

Note: Daktronics strongly recommends that only components from reputable domestic
suppliers be used to permanently suspend the scoreboard.

Remove immediately and do not use any assemblies that show evidence of excessive wear or
broken wires as defined by the component manufacturer.

Follow these procedures for installation:

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 assembly while it is on the arena floor.

3. Hang ends that attach to the ceiling over the sides of the scoreboards. If an end is too

short, attach a rope to the end temporarily so it can be returned from the top.

4. The scoreboard can be lifted into place in a number of different ways.

Note: It is the installer's responsibility to ensure that the installation is safe and that

the display meets OSHA or local regulations.

8 Mechanical Installation

Lifting Method Example: A common method of temporarily lifting the scoreboard is to use a
pair of chain-lift motors mounted on the ceiling. Secure prior approval 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 lift tubes.

Be sure the angle of the sling is greater than 45°.

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. Connect to power outlets (and signal junction boxes, if required) in the ceiling.

5. Level the scoreboard by adjusting the turnbuckle on the sling.

6. Lower the scoreboard weight onto the slings.

7. Remove the chain motors.

Electric Hoist System

Installing an electric hoist system is more complex and may expose the customer to greater
liability. Publication SL-03610 in Appendix F 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.

Note: Records of periodic inspections must be on file to be accessible for OSHA
(refer to Section 5.7).

 Electrical service and control wiring must be run to the hoist location.
 Additional structures in the ceiling are often required 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, refer to Section 3.10 for more information about attaching
the scoreboard to the hoist.

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 people are below the

scoreboard.

 When running 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.

Mechanical Installation 9

3.3 Assembly Overview

The assembly kit includes the following:

 Floor frame – 2 halves, 2 side splice plates, and 4 top & bottom splice plates
 Corner shrouds @ 4
 Shroud brackets @ 8
 Top corner brackets @ 4
 Assorted bolts, nuts, washers, and screws

In addition to the scoreboard pieces, an installation may also include:

 Upper and lower ad panels
 A message center at the top or bottom of the scoreboard

Each scoreboard face section is one piece and must be attached to the structural frame.
The frame is shipped in two parts and requires some assembly. Corner shrouds, which
provide cosmetic covering only, are attached to the display last.

Ad panels may simply be painted metal cabinets that do not need power, or they may be
backlit, requiring a 120 V circuit. An LED message center requires power as well as signal
wiring. The scoreboard itself requires power and signal wiring. The scoreboard tilts outward
at approximately 10°, while the ad panels or message centers are vertical (except for BB-2146
and BB-2147, where the opposite is true). Refer to Section A-A shown on the mechanical
specification drawings in Appendix A.

3.5 Optional Lower Ad Panel Attachment

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 to
be attached to the bottom. Refer to Drawing A-107664 in Appendix C.

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 while sitting on the arena floor.

Note: 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 assembled frame and support it on sturdy blocks or stands.

2. There are four holes in each corner of the frame on the bottom side. Secure a support

bracket in all four corners using 3/8" hardware.

3. Attach the rear flanges of the ad panels to the support brackets with

3

Each side of the frame has two mounting angles to which the bottom of each scoreboard
section will be attached. The tops of the scoreboard sections will be joined at their corners by
brackets. Refer to Drawing A-154598 in Appendix E for an illustration of the parts used in
this procedure.

1. Lift one scoreboard section into place on the frame, with the mounting angles inside

the bottom channel of the scoreboard section.

2. Align the holes along the bottom of the scoreboard's rear flange with the

threaded inserts on the mounting angles, and install the 1/4" bolts as shown in

Detail A of Drawing A-154598.

3. Ask for assistance as needed to support the scoreboard section and prevent it from

tipping as the second section is lifted into place adjacent to the first and secured to
the frame.

4. Join the two scoreboard sections at their common top corner using a top bracket and

3

/8" hardware as shown in Detail B of Drawing A-154598. Once the two sections are

joined, they will not require additional support during assembly.

5. Attach the third scoreboard section to the frame at the bottom and to the second

section at the top corners.

6. Attach the fourth scoreboard section to the frame at the bottom and to the third

section at the top corners.

3.7 Optional Top Ad Panel or Message Center Attachment

Reference Drawing:

Top 4-Side Ad Panel Mounting ............................................................... Drawing A-107665

Note: Make sure all power and signal wires are connected on top of the scoreboard
before mounting an ad panel/message center – it will be very difficult to make these
connections once upper display tiers have been added. Refer to Section 4.2.

Drawing A-107665 in Appendix E 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 brackets.

1. Attach the mounting strips to the top of the scoreboard. The mounting strips are

fitted with 1/4" threaded inserts. Two mounting strips are required for each ad
panel/message center.

a. Position a mounting strip inside the top channel of the scoreboard section,

aligned with the holes in the rear flange.

b. Use the

scoreboards. The tapered washers allow the ad panels/message centers to be
supported in a vertical position while the scoreboard remains tilted out 10°.

2. Lift one ad panel/message center into place atop the scoreboard section, and align

the holes along the bottom of the rear flange with the threaded inserts in the
mounting strips.

3. Insert and tighten

4. Ask for assistance as needed to support the ad panel/message center section and

prevent it from tipping as the second ad panel/message center is lifted into place
adjacent to the first and secured to the frame.

5. Join the two ad panel/message center sections at their common top corner using a

top bracket and 3/8" hardware. Once the two sections are joined at the top, they will
not require additional support during assembly.

6. Attach the third ad panel/message center section to the mounting strips on the top of

the scoreboard and to the second section at the top corners.

7. Attach the fourth ad panel/message center section to the mounting strips on the top

of the scoreboard and to the third section at the top corners.

3.9 Attaching Corner Shrouds

Reference Drawing:

4-Side Installation Details ....................................................................... Drawing A-154598

Note: Make sure all power and signal wires are connected on top of the scoreboard
before attaching the corner shrouds. Refer to Section 4.2.

The corner shrouds are metal panels that cover the outside corners of the four-sided assembly
and hide the wiring between sections. Separate shrouds are provided for each display tier.
Refer to Detail C of Drawing A-154598 in Appendix E for corner shroud installation details.

1. Position and attach angle brackets to the side channel of each scoreboard, ad panel, or

message center section with the #10 screws provided.

2. Position each corner shroud across the appropriate corner and mark the locations of

the holes on the angle brackets.

3. Drill

Sling Set: Standard 8' Square 4-Side Scoreboards ............................... Drawing A-181935

Sling Set: Standard 10' 4-Side Scoreboards .......................................... Drawing A-268195

The roof of the facility and any structures fabricated for suspending the scoreboard, as well as
the suspension cable slings, must be designed by or inspected and approved by a qualified
engineer. Drawing A-181903 and Drawing A-181935 in Appendix E show recommended
component specifications of cable slings (these are not typically provided by Daktronics).

Note: Refer to Drawing A-268195 for BB-2146 and BB-2147 models.

If the scoreboard is to be static mounted, that is, suspended from fixed cables without a hoist:

1. Attach the cables to the four lift tubes on the corner braces of the frame. The cables

may be connected together to make two attachment points, or all four cables may
attach to the roof trusses or the mounting structure.

2. Hang the top ends of the cables over the sides of the scoreboard to get them out of the

way yet keep 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 Installation 13

If the scoreboard is to be suspended from a hoist:

1. Attach the cable sling to the four lift tubes on the corner braces of the frame.

2. Lower the hoist cables and attach them to the master links.

3. Raise the scoreboard 1-2' (305-610 mm) from the floor, and level the scoreboard by

adjusting the turnbuckles built into the slings.

4. The hoist installer must set upper and lower primary limits and all safety limits.

Daktronics recommends maintaining a minimum of 2' (610 mm) between the
scoreboard and the nearest obstruction.

WARNING! Never raise or lower the scoreboard with personnel or equipment underneath!

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

Electrical installation for four-sided scoreboards involves routing power and control signal
wiring through separate conduit or wire ways to the scoreboard location, as well as routing
power and signal wiring from section to section.

The diagram shown in Figure 4 illustrates a typical wired setup between the first scoreboard
section and the control system. Daktronics part numbers are shown in parentheses.

Note: Control signal cable and some junction boxes are not provided as part of this
system and can be purchased locally or from Daktronics.

The diagram shown in Figure 5 illustrates a typical wireless setup between the first
scoreboard section and the control system. Refer to Section 6.2 for more information about
the wireless radio option.

4.2 Power/Signal Connections Between Sections

Reference Drawing:

Note: Be sure to make sectional power connections before connecting main power! It is also
recommended that these connections are made before the corner shrouds or optional top ad
panels/message centers are mounted into place.

Figure 6: Scoreboard Power & Signal Connection, Top View

 Scoreboard power and signal connectors are located on top of the scoreboard cabinet.

Input cables should be routed to the left, and output cables should be routed to the
right (as viewed from the front). The scoreboard section that will receive main
power/signal is designated “Face A”; all other sections are named in relation to it.

Power and signal flows to the right around the display from face output to face input.
Figure 7 shows the power and signal flow between sections. Main power and signal are
terminated last (refer to Sections 4.3 and 4.5, respectively).

 Backlit ad panel and message center connectors are located on the sides of the

cabinets. Inputs are on the left, and outputs are on the right (as viewed from the front).
Each message center requires its own power input, while backlit ad panels may be
daisy-chained together for power, like scoreboards. Message center signal connections
use 6-pin RJ45 quick connect cables; main signal may be wired or wireless.

Refer to Drawing A-154599 in Appendix E for connection details of power and signal
from one backlit ad panel or message display section to the next. Refer to Drawing
A-822860 for additional message center connection details.

Electrical Installation 17

Figure 7: Digit Segment POST

Note: Standard power cords and signal cables are about 10' (3 m) long. If a hoist is used
for this installation, all main power/signal cables must be long enough to allow the
display to be lowered. An optional sheet metal floor may contain the cables when the
scoreboard is raised. If the scoreboard is static-mounted, the cables only need to be long
enough to provide service. Neatly tie excess lengths out of the way.

4.3 Main Power Connection

Note: Be sure to make sectional power connections before connecting main power!

Each scoreboard section includes two 120 VAC power cords: one for Power In and one for
Power Out.

1. Install a grounded 120 VAC receptacle near the scoreboard/backlit ad panel location

(each message center will require its own power receptacle). Try to mount it so that
the power cord is easily accessible to plug in and hidden from view, such as centered
above the display.

2. Determine which scoreboard/backlit ad panel section is closest to the grounded

receptacle, and plug in its power cord.

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
universal power plugs.

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.

4.4 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 7 shows an
example of the LED bar test pattern that each digit performs.

18 Electrical Installation

Figure 8: Radio Settings in Clock Digits

Radio Settings

If a radio receiver is installed (see Section 6.2),
the radio broadcast settings (“b1”) and the
channel settings (“C1”) will be displayed in the
Home and Guest or clock digits (Figure 8)
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).

4.5 Main 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 E for signal wire connection.

Note: For message center signal installation, including for BB-2146 and BB-2147 models,
refer to the SS Series 20mm Indoor Scoreboard Message Centers Installation &
Operation Manual (DD1564453).

1. At a minimum, use a paired, 22 AWG shielded cable (Daktronics part # W-1077) and

connect the cable to a dual

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. Install a J-box near the scoreboard location. Try to mount it so that the signal cable is

easily accessible to plug in and hidden from view, such as centered above the display.

3. Route signal cable from the J-box on the control console end to the J-box at the

display end.

4. Install the

1

/4" phone plug (Daktronics part # 0L-40683) to the display end of the

cable. Be sure to connect the cable shielding only in the J-box on this end.

5. Insert the plug into the J31 - SIGNAL IN jack located on the top of the scoreboard

section closest to the J-box.

6. Connect a signal cable from the J-box on the control console end to the J1, J2, or J3

jack on the back of the All Sport 5000 console.

If using a Main Clock Start/Stop Switch (Daktronics part # 0A-1166-0003), connect it
to the J4 jack on the All Sport 5000 console.

refer to the SS Series 20mm Indoor Scoreboard Message Centers Installation & Operation
Manual (DD1564453).

5.2 Component Location & Access

All Tuff Sport indoor basketball 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.

Component location varies with each scoreboard model,
but drivers and power and signal components are
typically mounted inside the scoreboard behind a digit
panel. To locate the driver(s), look for a warning label
similar to that shown in Figure 9.

Refer to the electrical and signal specification drawings in
Appendix B for model-specific component layouts and
access locations.

Figure 13: Driver Enclosure Location & Components

5.4 LED Drivers

In each scoreboard, one or more LED drivers perform the task of switching LEDs on and off.
LED drivers are located inside of a driver enclosure. Refer to Figure 13 to view the location
and components of a Tuff Sport driver enclosure.

All scoreboards in this manual use 16-column drivers (Figure 13). Some scoreboard models
contain more than one driver to accommodate all of the digits and indicators. Refer to the
electrical and signal specifications in Appendix B to determine the type and number of
drivers for a particular scoreboard model.

Each driver has numerous connectors providing power and signal inputs and outputs to the
scoreboard digits and indicators. The table on the following page shows the function of these
connectors for a 16-column driver:

Replacing a Driver

If the driver status indicators do not appear to be working correctly, it may be necessary to
replace the driver.

1. Open the digit panel or scoreboard face panel as described in Section 5.2.

2. Disconnect all connectors from the driver by squeezing together the locking tabs and

pulling the connectors free.

Note: It may be helpful to label the cables to know which cable goes to which

connector when reattaching the driver.

3. Remove the wing nuts securing the driver to the driver tray.

4. Carefully lift the driver from the display and place it on a clean, flat surface.

5. Position a new driver over the screws and tighten the nuts.

6. Reconnect all power/signal connectors.

Note: The connectors are keyed and will attach in one way only. Do not attempt to
force the connections.

7. Ensure the driver is set to the correct address (refer to Setting the Driver Address).

8. Close and secure the access panel, then power up and test the scoreboard to see if

changing the driver has resolved the problem.

Setting the Driver Address

Since the same LED drivers can be used for many
scoreboard models, each driver must be set to receive
the correct signal input, or address, for the model
being used. This address is set with jumper wires in a
12-pin plug which mates with jack J19 on the driver
(Figure 15).

It may be possible to reuse the same address plug
from the driver that was replaced. If not, first refer to
the specifications table in Section 2 to find the correct
driver address(es) for a particular scoreboard model.
Then refer to Drawing A-115078 in Appendix E for a
listing of the wire/pin connections for driver
addresses 1 – 128.

Multiple Drivers

Scoreboards that require multiple drivers operate using a master/slave driver configuration.
Master and slave drivers function identically, but slave units lack the power/signal
termination blocks. The two drivers have been designed to simply plug into one another, and
this is done at the factory, so no additional on-site connection is necessary.

If it appears as though only a certain group of digits on the scoreboard is not functioning,
there may be a problem with the slave driver(s) or the power/signal connection from the
other driver(s).

5.5 Segmentation and Digit Designation

In each digit, certain LEDs always go on and off together. These groupings of LEDs are called
segments. Drawing A-38532 in Appendix E details which connector pin is wired to each digit
segment and the wiring color code used throughout the display.

The electrical and signal specification drawings in Appendix B specify the driver connectors
controlling the digits. Numbers shown in hexagons in the upper half of each digit indicate
which connector is wired to that digit.

5.6 Schematics

For advanced scoreboard troubleshooting and repair, it may be necessary to consult the
schematic drawings. Located in Appendix D, schematic drawings show detailed power and
signal wiring diagrams of internal display components such as drivers, horn interface cards,
and transformers as well as optional components like TNMCs and radio receivers.

5.7 Suspension System Periodic Inspections

Suspension systems need to be inspected periodically. Listed below are instructions and
information about such inspections.

Static System

A static-hung system should be inspected one year after initial installation and once every
five years thereafter.

 Inspect cable assemblies for broken wires, crushes, or kinks.
 Inspect components, per manufacturer's recommendations, for deformations.
 Inspect the four-sided scoreboard for any loose or missing bolts.
 Inspect the attachment bracket for loose bolts or cracks in members or welds.
 Check torque on all wire rope clips.

Hoist System

Hoist systems must be inspected annually per OSHA requirements. Some local governing
bodies require more frequent inspections. See the hoist manufacturer's manual for inspection
procedures.

 Inspect cable assemblies for broken wires, crushes, or kinks.
 Inspect connections for loose bolts or cracks in members or welds.

Be sure to document all inspections. Any irregularities must be addressed immediately.
For installation problems, call the original installer; for hoist problems, contact the hoist

Section 6: Scoreboard Options

6.1 Horns

Daktronics Tuff Sport scoreboards are equipped with a 120 VAC vibrating horn mounted
behind the scoreboard face. The horn sounds automatically when the period clock counts
down to zero, or when manually triggered by the operator using the control console.

Installation of an optional 12 VDC horn is detailed in Drawing A-148960 in Appendix C.
Louder trumpet horns are also available. Contact Daktronics for information and pricing.

Adjusting Horn Volume

CAUTION: The scoreboard horn is a 120 VAC device. Turn off the power to the scoreboard
before adjusting the horn.

The volume for the electronic, buzzer-type horn 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.

Note that with the noise of spectators, the horn will not seem as loud as when it is being
tested in an empty area, so be sure to set the volume according to the acoustics of the facility.

6.2 Radio Control

Radio control is an option for Daktronics Tuff Sport scoreboards. The system provides
scoreboard control via a 2.4 GHz, extra-high frequency FM signal.

The radio transmitter and receiver are not standard equipment. This setup requires a control
console equipped with a radio transmitter as well as a radio receiver plugged into the
driver/power enclosure and mounted internally to the front panel of the scoreboard.

For additional information about this option, contact a Daktronics representative; for
complete information on setting up radio communication control, refer to the Gen V Radio
Installation Manual (ED-13831) or the Gen VI Radio Installation Manual (DD2362277),
both available online at www.daktronics.com/manuals.

6.3 Visual Horn Indicator (VHI)

In addition to the horn, Daktronics offers both incandescent and LED visual horn indicators
that light up when the buzzer sounds. To install the VHI, users must tap into the existing
horn wiring to provide power and signal. For more information about installing the VHI
options, refer to the Visual Horn Indicator Installation Instructions (ED-13397) or the
BB-2133 LED Indicator Installation Instructions (ED-13806). Both manuals are available
online at www.daktronics.com/manuals.

Scoreboard Options 33

6.4 Changeable Captions

Team name and statistics caption kits contain hardware for one caption only and consist of an
upper caption retainer, a lower caption retainer, a changeable caption panel and screws.

The standard HOME and GUEST captions are applied directly to the face of the scoreboard.
Team name captions are on changeable panels that fit into retainers mounted above and
below the standard captions. If these retainers are not already present, attach the retainers
included with the caption kit.

Refer to Drawing A-150021 in Appendix C for changeable caption installation instructions.

6.5 Double Bonus Indicators

All of the clock/score basketball scoreboards in this manual have the option to include
double-bonus indicators, which are factory installed. This option is illustrated in the electrical
and signal specification drawings in Appendix B for each scoreboard model.

6.6 Time Outs Left (TOL) Digits

Certain scoreboards have the option to add a time outs left (TOL) digit for both the home and
guest teams. These digits are installed by simply unscrewing the blank face panel, connecting
and securing the digit, and manually applying the “T.O.L.” caption. Refer to Drawing A-
149030 in Appendix C for more information.

Section 7: TNMC Troubleshooting & Maintenance

IMPORTANT NOTES:

1. Always disconnect scoreboard power before doing any repair/maintenance work on the
message centers.

2. Permit only qualified service personnel to access internal display electronics.

3. Disconnect power when not using the scoreboard.

7.1 Display Overview

Team Name Message Centers (TNMCs) are programmable LED displays that allow users to
show custom Home and Guest names or messages of ~15 characters on the scoreboard in
place of static vinyl captions. TNMCs are typically ordered factory-installed, but they may
also be field-mounted after the scoreboard is in place. Characters are shown on one line using
single- or double-stroke fonts.

Primary matrix size is 8x48 with 0.75" pixel spacing. Figure 16 shows an example of TNMCs.

* Weight shown is for a pair of displays.

7.4 Power & Signal Summary

Reference Drawings:

Schematic: 3/4" and 1" DC TNMC’s ...................................................... Drawing B-146975

Refer to Drawing B-146975 in Appendix D for detailed schematics about display power and
signal routing.

Display signal routing can be summarized as follows:

1. Data from the All Sport

2. The signal then travels through the driver, typically re-driven from the driver TB-31

to the current loop interface (CLI) cards located on the right-hand module of each
display.

3. A ribbon cable harness carries the signal to the first LED module, and the signal

relays from module to module via ribbon cable in daisy-chain style until it reaches
the last module in the display.

Display power routing can be summarized as follows:

1. Incoming power from the power cord terminates at the main scoreboard LED driver tray.

2. Using interconnect harnesses, the power is passed from the driver tray to the Home

display power supply, and then to the Guest display power supply.

3. Power from the power supplies is relayed to all display modules.

4. The modules draw their power directly from the power supply assemblies; the

display driver receives power out from the first module via ribbon cable.

®

controller travels via signal cable (or radio) into the scoreboard.

7.5 Component Locations & Access

Reference Drawings:

Installation, 6" Amber 8x48 TNMC .......................................................... Drawing A-148701

To access the internal components of the display, simply remove the two screws on either
side of the face panel that secure it to the scoreboard. Carefully remove the face panel from
the scoreboard, as there will be several cables connected to it.

Drawing A-148701 in Appendix C provides a detailed view of each display component and
the connections between them.

7.6 Display Drivers

Reference Drawings:

A/S 5000 Capable TNMC Shift Card; Specifications .............................. Drawing A-123794

Display drivers, also known as controllers or shift cards, use a 12-pin plug that mates with
jack J4 to set the address. For TNMCs, the address plug is set to 1 (221). Pin 11 on the address
plug selects whether the display shows Guest (default) or Home data. Refer to Drawing
A-123794 in Appendix E for addressing information.
