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.

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.

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.
