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:
ƒ
“TB _ _” denotes a termination block for power or signal cable.
ƒ
“F _ _” denotes a fuse.
ƒ
“E _ _” denotes a grounding point.
ƒ
“J _ _” denotes a power or signal jack.
ƒ
“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.)
ƒ
“0P- _ _ _ _- _ _ _ _” denotes an individual circuit board, such as a driver
board.
ƒ
“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.
ƒ
“W- _ _ _ _ ” denotes a wire or cable. Cables may also carry the assembly
numbering format in certain circumstances. This is especially true for
ribbon cables.
ƒ
“F- _ _ _ _ ” denotes a fuse .
ƒ
“T- _ _ _ _ ” denotes a transformer.
ƒ
“PR- _ _ _ _ _ - _” denotes a specially ordered part.
ƒ
“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.
