Section 3: Mechanical Installation

Mechanical installation consists of lifting and permanently mounting the shot clocks. 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 Display

Small Daktronics scoreboards use two lifting straps that encircle the scoreboard. It is
recommended to use a spreader bar with the straps.

Note: Daktronics assumes no liability for damages resulting from incorrect setup or
lifting methods.

3.2 Shot Clock Mounting

BB-2140 and BB-2150 shot clocks are mounted behind and above the top center of the
backboard with included hardware. Due to game play, these shot clocks will be exposed to a
lot of movement and vibration. The brackets need to be designed to minimize vibration and
shot clock movement.

BB-2141 and BB-2151 shot clocks are mounted on the rear of the backstop, perpendicular to
the backboard with included hardware. Refer to Drawing A-184787 and Drawing A-1060357
in Appendix A for the approximate location to mount both shot clocks sizes on the backstop.

3.3 Control Enclosure Mounting

IMPORTANT: The control enclosure must be located within 30' (9.1 m) of the shot clock.

Mount on the base of the backstop with four #10 self-drilling screws. Power and signal from
the control console will be routed to the enclosure.

3.4 Remote Horn Enclosure Mounting

Use two #10 self-drilling screws to mount the remote horn enclosure in an open location so
that sound is able to radiate. A 20' (6.1 m) pre-attached cable is included, but this cable may
be extended to mount the horn enclosure further away from the control enclosure if needed.

3.5 Camera Mounting

If a camera is to be added (BB-2140 and BB-2150 only), camera mounts accepting two inch
pipe are available; only one may be used at a time. A cable tray can be used to route camera
wiring down either side of the shot clock. Refer to Drawing B-249064 in Appendix A.

Note: Total weight of the camera and mounting arm cannot exceed 50 lb (23 kg). Design
mounting brackets to accommodate both the shot clock and the camera.

Mechanical Installation 7

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 involves routing power and control signal wiring through separate
conduit or wire ways.

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

4.2 Power

Install a grounded receptacle near the equipment so that the power cord can easily reach it.

Each shot clock control enclosure comes with a 120 V AC or 230 V AC twist lock power plug.
The power plug will need to be attached to a 120 V AC or 230 V AC power cord (by the
customer) as follows:

 120 V AC wiring: Connect black wire to copper terminal, white wire to nickel

terminal, and green wire to green terminal.

 230 V AC wiring: Connect black wire to copper terminal, red wire to copper terminal,

and green wire to green terminal.

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.

Electrical Installation 9

Figure 4: Digit Segment POST

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

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 game 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 1.4).

4.4 Signal Connection

Signal installation requires routing cable from the control console to a signal junction box near
the display, routing cable from the junction box to the control enclosure, and routing the
appropriate cables from the system components to the control enclosure.

1. At a minimum, use a paired, 22 AWG shielded cable (Daktronics part number W-

1077) and connect the cable to a ¼" J-box at the control console end.

2. Route the cable from the J-box on the control console end to a J-box near the display.

3. Install the ¼ inch phone plug cable (Daktronics part number 0L-40683) to the

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

Note: DO NOT connect cable shielding at the J-box near the control console.

4. Insert the plug into the Signal In (J31) jack on the front of the control enclosure.

5. Connect the shot clock(s), remote horn enclosure, and any optional light strip kits to

the appropriate jacks on the control enclosure as shown in Drawing A-184789 and
Drawing A-1060264 in Appendix A.

6. Connect a signal cable from the J-box to the J1, J2, or J3 jack on the back of the All

Sport 5000 console. Also connect the Shot Clock Start/Stop Switch (Daktronics part
number 0A-1196-0031) to the J7 jack on the All Sport 5000.

14 Scoreboard Troubleshooting

Figure 7: Address Jack J1

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 control enclosure by removing the 6 screws and swinging the door open.

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 4 nuts securing the driver to the enclosure door.

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

5. Position a new driver over the standoffs 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 enclosure door, 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 J1 on the driver
(Figure 7).

After replacing the driver in the control enclosure, be
sure to use an Address 1 plug in jack J1. In most cases,
the same plug can be reused from the driver that was
replaced; otherwise, one may be ordered from
Daktronics (part number 0A-1150-0122).

Note: For BB-2150 and BB-2151 to display 1/10 of
a second, switch 8 of DIP switch S3 must be set to ON.
Refer to Drawing B-216653 in Appendix A for more information on DIP switch settings.

5.4 Schematics

DAKTRONICS

WARRANTY AND LIMITATION OF LIABILITY

This Warranty and Limitation of Liability (the “Warranty”) sets forth the warranty provided by Daktronics with respect to the Equipment. By
accepting delivery of the Equipment, Purchaser agrees to be bound by and accept these terms and conditions. All defined terms within
the Warranty shall have the same meaning and definition as provided elsewhere in the Agreement.

DAKTRONICS WILL ONLY BE OBLIGATED TO HONOR THE WARRANTY SET FORTH IN THESE TERMS AND CONDITIONS UPON RECEIPT OF FULL
PAYMENT FOR THE EQUIPMENT.

1. Warranty Coverage

2. Exclusion from Warranty Coverage

A. Daktronics warrants to the original end-user that the Equipment will be free from Defects (as defined below) in materials and
workmanship for a period of one (1) year (the “Warranty Period”). The warranty period shall commence on the earlier of: (i) four
weeks from the date that the equipment leaves Daktronics’ facility; or (ii) Substantial Completion as defined herein. The warranty
period shall expire on the first anniversary of the commencement date.

“Substantial Completion” means the operational availability of the Equipment to the Purchaser in accordance with the
Equipment’s specifications, without regard to punch-list items, or other non-substantial items which do not affect the operation of

the Equipment.

B. Daktronics’ obligation under this Warranty is limited to, at Daktronics’ option, replacing or repairing, any Equipment or part
thereof that is found by Daktronics not to conform to the Equipment’s specifications. Unless otherwise directed by Daktronics,

any defective part or component shall be returned to Daktronics for repair or replacement. Daktronics may, at its option,
provide on-site warranty service. Daktronics shall have a reasonable period of time to make such replacements or repairs and
all labor associated therewith shall be performed during regular working hours. Regular working hours are Monday through
Friday between 8:00 a.m. and 5:00 p.m. at the location where labor is performed, excluding any holidays observed by either
Purchaser or Daktronics.

C. Daktronics shall pay ground transportation charges for the return of any defective component of the Equipment. If returned
Equipment is repaired or replaced under the terms of this warranty, Daktronics will prepay ground transportation charges back to
Purchaser; otherwise, Purchaser shall pay transportation charges to return the Equipment back to the Purchaser. All returns must
be pre-approved by Daktronics before shipment. Daktronics shall not be obligated to pay freight for any unapproved return.
Purchaser shall pay any upgraded or expedited transportation charges.

D. Any replacement parts or Equipment will be new or serviceably used, comparable in function and performance to the
original part or Equipment, and warranted for the remainder of the Warranty Period. Purchasing additional parts or Equipment
from the Seller does not extend this Warranty Period.

E. Defects shall be defined as follows. With regard to the Equipment (excepting LEDs), a “Defect” shall refer to a material
variance from the design specifications that prohibit the Equipment from operating for its intended use. With respect to LEDs,
“Defects” are defined as LED pixels that cease to emit light. The limited warranty provided by Daktronics does not impose any
duty or liability upon Daktronics for partial LED pixel degradation. Nor does the limited warranty provide for the replacement or
installation of communication methods including but not limited to, wire, fiber optic cable, conduit, trenching, or for the purpose
of overcoming local site interference radio equipment substitutions.

THIS LIMITED WARRANTY IS THE ONLY WARRANTY APPLICABLE TO THE EQUIPMENT AND REPLACES ALL OTHER WARRANTIES OR
CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OR CONDITIONS OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. SPECIFICALLY, EXCEPT AS PROVIDED HEREIN, THE SELLER
UNDERTAKES NO RESPONSIBILITY FOR THE QUALITY OF THE EQUIPMENT OR THAT THE EQUIPMENT WILL BE FIT FOR ANY PARTICULAR
PURPOSE FOR WHICH PURCHASER MAY BE BUYING THE EQUIPMENT. ANY IMPLIED WARRANTY IS LIMITED IN DURATION TO THE
WARRANTY PERIOD. NO ORAL OR WRITTEN INFORMATION, OR ADVICE GIVEN BY THE COMPANY, ITS AGENTS OR EMPLOYEES,
SHALL CREATE A WARRANTY OR IN ANY WAY INCREASE THE SCOPE OF THIS LIMITED WARRANTY.

THIS LIMITED WARRANTY IS NOT TRANSFERABLE.

The limited warranty provided by Daktronics does not impose any duty or liability upon Daktronics for:

A Any damage occurring, at any time, during shipment of Equipment unless otherwise provided for in the Agreement. When
returning Equipment to Daktronics for repair or replacement, Purchaser assumes all risk of loss or damage, and agrees to use
any shipping containers that might be provided by Daktronics and to ship the Equipment in the manner prescribed by
Daktronics;

B. Any damage caused by the unauthorized adjustment, repair or service of the Equipment by anyone other than personnel of
Daktronics or its authorized repair agents;

C. Damage caused by the failure to provide a continuously suitable environment, including, but not limited to: (i) neglect or
misuse, (ii) a failure or sudden surge of electrical power, (iii) improper air conditioning or humidity control, or (iv) any other cause
other than ordinary use;

D. Damage caused by fire, flood, earthquake, water, wind, lightning or other natural disaster, strike, inability to obtain materials
or utilities, war, terrorism, civil disturbance or any other cause beyond Daktronics’ reasonable control;

E. Failure to adjust, repair or replace any item of Equipment if it would be impractical for Daktronics personnel to do so because
of connection of the Equipment by mechanical or electrical means to another device not supplied by Daktronics, or the
existence of general environmental conditions at the site that pose a danger to Daktronics personnel;

F. Any statements made about the product by salesmen, dealers, distributors or agents, unless such statements are in a written
document signed by an officer of Daktronics. Such statements as are not included in a signed writing do not constitute
warranties, shall not be relied upon by Purchaser and are not part of the contract of sale;

G. Any damage arising from the use of Daktronics products in any application other than the commercial and industrial
applications for which they are intended, unless, upon request, such use is specifically approved in writing by Daktronics; or

H. Any performance of preventive maintenance.

3. Limitation of Liability

4. Assignment of Rights

5. Dispute Resolution

6. Governing Law

7. Availability of Extended Service Agreement

Daktronics shall be under no obligation to furnish continued service under this Warranty if alterations are made to the Equipment
without the prior written approval of Daktronics.

It is specifically agreed that the price of the Equipment is based upon the following limitation of liability. In no event shal l
Daktronics (including its subsidiaries, affiliates, officers, directors, employees, or agents) be liable for any special, consequential,
incidental or exemplary damages arising out of or in any way connected with the Equipment or otherwise, including but not
limited to damages for lost profits, cost of substitute or replacement equipment, down time, lost data, injury to property or any
damages or sums paid by Purchaser to third parties, even if Daktronics has been advised of the possibility of such damages. The
foregoing limitation of liability shall apply whether any claim is based upon principles of contract, tort or statutory duty, principles
of indemnity or contribution, or otherwise.

In no event shall Daktronics be liable to Purchaser or any other party for loss, damage, or injury of any kind or nature arising out of
or in connection with this Warranty in excess of the purchase price of the Equipment actually delivered to and paid for by the
Purchaser. The Purchaser’s remedy in any dispute under this Warranty shall be ultimately limited to the Purchase Price of the
Equipment to the extent the Purchase Price has been paid.

The Warranty contained herein extends only to the original end-user (which may be the Purchaser) of the Equipment and no
attempt to extend the Warranty to any subsequent user-transferee of the Equipment shall be valid or enforceable without the
express written consent of Daktronics.

Any dispute between the parties will be resolved exclusively and finally by arbitration administered by the American Arbitration
Association (“AAA”) and conducted under its rules, except as otherwise provided below. The arbitration will be conducted
before a single arbitrator. The arbitration shall be held in Brookings, South Dakota. Any decision rendered in such arbitration
proceedings will be final and binding on each of the parties, and judgment may be entered thereon in any court of competent
jurisdiction. This arbitration agreement is made pursuant to a transaction involving interstate commerce, and shall be governed
by the Federal Arbitration Act.

The rights and obligations of the parties under this warranty shall not be governed by the provisions of the United Nations
Convention on Contracts for the International Sales of Goods of 1980. Both parties consent to the application of the laws of the
State of South Dakota to govern, interpret, and enforce all of Purchaser and Daktronics rights, duties, and obligations arising
from, or relating in any manner to, the subject matter of this Warranty, without regard to conflict of law principles.

For Purchaser’s protection, in addition to that afforded by the warranties set forth herein, Purchaser may purchase extended
warranty services to cover the Equipment. The Extended Service Agreement, available from Daktronics, provides for electronic
parts repair and/or on-site labor for an extended period from the date of expiration of this warranty. Alternatively, an Extended
Service Agreement may be purchased in conjunction with this warranty for extended additional services. For further information,
