How to Use This Manual

This manual explains the installation, maintenance, and troubleshooting of this video

display system. For additional information regarding the safety, installation, operation,

or service of this system, refer to the telephone numbers listed in Daktronics Exchange

and Repair & Return Programs (p.7). This manual contains only generic installation

topics and is not specic to a particular installation. Contract-specic information takes

precedence over any general information found in this manual.

Daktronics identies manuals by the DD number located on the cover page of each

manual. For example, this manual would be referred to as DD3699883.

Numbering Conventions

Drawing Numbers

Figure 1 illustrates a Daktronics drawing label.

This manual refers to drawings by listing the

last set of digits. In the example, the drawing

would be referred to as DWG-3331467.

All references to drawing numbers,

appendices, gures, or other manuals are

presented in bold typeface, as shown in the

example below:

Refer to DWG-3331467 in Section B: Reference Drawings (p.13) for the locations of

internal display components.

Part Numbers

Most display components within a display carry a white

label that lists the part number. The component part

number uses the following format: 0A-XXXX-XXXX

(multi-component assembly) or 0P-XXXX-XXXX (display

interface board). Daktronics Exchange and Repair

& Return Programs (p.7) contains the Daktronics

Exchange Policy as well as the Repair & Return Program.

Refer to these instructions if any display components need

replacing or repairing. If an interface board or assembly is not found in the replacement

parts list in Replacement Parts List (p.7), use the label to order a replacement. Figure 2

illustrates a typical label. The part number is in bold.

Daktronics numbers modules on a video display.

A 2 0 3

Used to differentiate display face if system has

more than one viewing face

“A” denotes the rst face, “B” the second, etc.

First number denotes module row number

Top row of modules is Row 1

Last two numbers denote position in row,

counting left to right

Model Numbers

Each video display system has a model

number that explains the display

specications.

Important Safeguards

• Read and understand the installation

instructions before beginning the

installation process.

• Do not drop the control equipment or

allow it to get wet.

• Do not disassemble the control equipment or electronic controls of the display; failure

to follow this safeguard will make the warranty null and void.

• Disconnect the display power when not in use or when servicing.

• Disconnect the display power before servicing the power supplies to avoid electrical

shock. The power supplies run on high voltage and may cause injury if touched while

powered.

Warnings/Disclaimers

Review the reference documents and drawings in Section A: Reference Documents

(p.11) and Section B: Reference Drawings (p.13) prior to installation as well as during

the installation process.

Display

Daktronics engineering staff must approve any changes that may affect the strength

or protective integrity of the display frame or enclosures. If any modications of this

nature are made, detailed drawings of the change(s) must be submitted to Daktronics

engineering staff for evaluation and approval, or the warranty will be null and void.

Displays must be lifted appropriately to ensure the display sections will not be damaged.

Introduction

Structure

It is the installer’s responsibility to ensure the mounting structure and hardware are built

per the stamped engineering drawings and are capable of supporting the display prior

to beginning the installation.

Display Installation

It is the installer’s responsibility to ensure the installation meets all local codes and

standards. All hardware processes used during display installation must meet the

approved, stamped drawings from a professional engineer.

This display is intended to be installed in accordance with the requirements of Article 600

of the National Electrical Code and/or other applicable local codes. This includes proper

grounding and bonding of the sign.

This display is suitable for wet locations. Daktronics engineering staff must approve any

changes that may affect the weather tightness of the display. If any modications are

made to the weather tightness of the display, detailed drawings of the changes must be

submitted to Daktronics engineering staff for evaluation and approval, or the warranty

will be null and void.

Only qualied individuals should access the electrical components of this display and its

associated equipment.

Glossary

2 Glossary

Lanyard attachment ring: a ring found on the back of each module. The lanyard

attaches to the ring to keep the module from falling to the ground.

Latch release: a device that holds the module rmly to the display frame. There are two

per module, one on the top and one on the bottom.

Light emitting diode (LED): a low energy, high intensity lighting unit.

Line lter: a device that removes electromagnetic noise from the power system to

avoid interference with local communications channels. Line lters sometimes mount on

brackets with power supplies. Other times they may mount alone on a bracket.

Louver: a plastic shade positioned horizontally above each pixel row. Louvers increase

the contrast level on the display face and direct LED light for easier viewing.

Module: a display board with LEDs, a driver board or logic card, a black plastic housing,

and a module latch assembly. Each module is individually removable from either the

front or the rear of the display.

Pixel: the smallest single point of light on a display that can be turned on and off. For

LED displays, a pixel is the smallest block of light emitting devices that can generate all

available colors.

Power supply: a device that converts AC line voltage from the termination panel to

low DC voltage for one or more module driver boards. One power supply may power

multiple modules.

ProLink Router (PLR): a display interface board that passes display data from the ProLink6

control system modules and other PLRs. The ratio of PLRs to modules varies with

display application.

Termination block: an electrical point usually used to connect internal power and signal

wires to wires of the same type coming into the display from an external source.

Video Image Processor (VIP): an interface that drives video to the display while also

dimming, providing gamma and color controls, and displaying test patterns.
