Section 1: Introduction
This manual explains the installation of Daktronics Multi-Section Outdoor LED
Scoreboards and provides details for display maintenance. For other questions regarding the
safety, installation, operation or service of these systems, contact Daktronics Customer
Service at 1-877-605-1115. Customer Service information is listed in Section 8.9 of this
manual.
1.1 How to use this manual
Important Safeguards:
•Read and understand these instructions before installing the display.
•Do not drop the control console or allow it to get wet.
•Properly ground the scoreboard with a grounding electrode at the
scoreboard location.
•Disconnect power when the scoreboard is not in use.
•Disconnect power when servicing the scoreboard.
•Do not modify the scoreboard structure or attach any panels or
coverings to the scoreboard without the express written consent of
Daktronics, Inc.
Figure 1 illustrates the Daktronics drawing numbering system. Daktronics identifies
individual engineering drawings by their drawing number (7087-P08A-69945 in the
example), which is located in the lower right corner of the drawing. This manual
refers to drawings by their last set of numbers and the letter preceding them. The
example would be Drawing A-69945.
Figure 1: Daktronics Drawing Label
Reference drawings are grouped and inserted in alphanumeric order in Appendix A
and Appendix B.
Listed below are a number of drawing types commonly used by Daktronics, along
with the information that each is likely to provide.
System riser diagrams: overall system layout from control room to
display, power and phase requirements.
Introduction 1-1

Shop drawings: fan locations, transformer locations, mounting
information, power and signal entrance points and access method (front or
rear).
Schematics: power wiring, signal wiring, panelboard or power termination
panel assignments, signal termination panel assignments and transformer
assignments.
Final assembly: component locations, part numbers, display dimensions
and assembly/disassembly instructions.
All references to drawing numbers, appendices, figures, or other manuals are
presented in bold typeface, as in this example: “Refer to Drawing A-69945 for the
location of the driver enclosure.” Additionally, any drawings referenced within a
particular subsection are listed at the beginning of that subsection in the following
manner:

Daktronics identifies manuals by their engineering document (ED) number, which is
located on the cover page of the manual. For example, this manual would be referred
to as ED-16960.
The serial and model numbers of a Daktronics scoreboard can be found on the ID
label on the display. The label will be similar to the one shown in Figure 2. When
calling Daktronics Customer Service, please have this information available to
ensure that your request is serviced as quickly as possible. For future reference, note
your scoreboard model number, serial number and installation date on the second
page of this manual.

Daktronics displays are built for long life and require little maintenance. However,
from time to time, certain display components will have to be replaced. The
Replacement Parts List in Section 8.8 provides the names and part numbers of
components that may require replacement during the life of this display.
Following the Replacement Parts List is an explanation of Daktronics exchange and
replacement programs. Refer to these instructions if repaired or replacement parts are
needed.
1.2 Daktronics Nomenclature
To fully understand some Daktronics drawings, such as schematics, it is necessary to
know how various components are labeled in those drawings. This information is
useful when trying to communicate maintenance or troubleshooting efforts.
The label “A” on a drawing item typically denotes an assembly. An assembly can be
1-2 Introduction

Introduction 1-3
a single circuit board or a collection of components that function together, usually
mounted on a single plate or in a single enclosure.
In addition, the following labeling formats might be found on various Daktronics
drawings:
“TB _ _” denotes a termination block for power or signal cable.
“F _ _” denotes a fuse.
“E _ _” denotes a grounding point.
“J _ _” denotes a power or signal jack.
“P _ _” denotes a power or signal plug for the opposite jack.
Finally, Daktronics part numbers are commonly found on drawings. Those part
numbers can be used when requesting replacement parts from Daktronics Customer
Service. Take note of the following part number formats. (Not all possible formats
are listed here.)
“0P- _ _ _ _- _ _ _ _” denotes an individual circuit board, such as a driver
board.
“0A-_ _ _ _ - _ _ _ _” denotes an assembly, such as a circuit board and the
plate or bracket to which it is mounted. A collection of circuit boards
working as a single unit may also carry an assembly label.
“W- _ _ _ _ ” denotes a wire or cable. Cables may also carry the assembly
numbering format in certain circumstances. This is especially true for
ribbon cables.
“F- _ _ _ _ ” denotes a fuse.
“T- _ _ _ _ ” denotes a transformer.
“PR- _ _ _ _ _ - _” denotes a specially ordered part.
“M- _ _ _ ” denotes a metal part, and “0S-_ _ _ _ _ _” typically denotes a
fabricated metal assembly.
1.3 Product Overview
The Daktronics outdoor LED scoreboards are part of a family of scoring and timing
displays designed to offer easy installation, readability, and reliability.
Microprocessor control assures consistent operation and accuracy.
Featuring large, highly visible PanaView®digits 15, 18, 24, and 30" tall, the
scoreboards use light emitting diodes, or LEDs, to illuminate the display. LEDs are
tiny, solid-state components that use a semiconductor chip to transform electrical
current into light; they are high-intensity, low-energy lighting units. Scoreboards in
this series typically use red or amber LEDs for optimum outdoor readability.
Because of their LED technology, the scoreboards consume little power – barely
more than a single household lamp. Power usage for displays in this series ranges
from 300 W to a maximum of 1500 W.
Each of the sections in this manual contains model-specific information, including
physical dimensions, digit configuration, and power requirements. The scoreboard
engineering drawings, located in Appendix A, also list dimensions, weight and
mounting instructions for each display. Additionally, scoreboard model numbers and
electrical requirements can be found on a label on the scoreboard entrance panel.

1-4 Introduction
The outdoor LED displays are modular in construction, typically with a top and a
bottom section, but some are comprised of as many as four different sections. The
units are shipped separately and joined at installation. Unpowered sections,
connected to the internal power and signal enclosure with cabling, are referred to as
“slave” sections, while those housing the electronic control components are
“masters.”
Cabinets for the displays, available in more than 150 colors, are constructed of
heavy-gauge aluminum. Digit and indicator faceplates are black, and they are set
directly into the scoreboard surface. Permanent captions and optional striping are
white vinyl.
Note: Some drawings and text in this manual refer to team name message centers or
TNMCs.
Team name message centers are scoreboard-mounted, matrix LED units, which
electronically display home and guest team names. TNMCs are available as a
standard new scoreboard option with several of the models in this series, and the
message centers are also available for retrofit on existing scoreboards. Section 9 of
this manual offers step-by-step information on TNMC maintenance and
troubleshooting.
The outdoor LED scoreboards are designed for use with an All Sport®5000 Series
control console. The console uses All Sport keyboard overlays
(sport inserts) for game control, and the boards operate without modification on All
Sport 5000 signal protocol. Refer to the following controller manual for operating
instructions:
ED-11976: All Sport 5000 Series Control Console Operation Manual
1.4 Model Names
Daktronics scoreboards are differentiated by their model numbers: BA-1518, for
example, designates a specific baseball scoreboard. The two-letter prefixes for
scoreboards in this manual include the following: BA – baseball; CR – cricket; FB –
football; MS – multisport; and SO – soccer.
Most Daktronics scoreboards carry a two-number suffix that refers to indoor-outdoor
status and digit color: -11 are outdoor scoreboards, 120 V and they feature red digits;
-21 are outdoor scoreboards, 120 V and feature amber digits.
1.5 Product Safety Approval
Daktronics outdoor scoreboards are ETL listed and tested to CSA standards for
outdoor use. Contact Daktronics for information regarding testing procedures.
