Introduction

1.2 Network Concepts

The concept of using LED displays as a cost effective, high impact method of
communication is rapidly growing throughout many industries and businesses. The
reasons for this growth are many, but the need for additional features and the
complexity of multiple display installations has emerged. Daktronics display systems
have been designed to meet those needs.

The common thread to most client requests is a means of programming and
controlling a group of displays from a central control point. Daktronics responded by
developing a powerful system of interconnecting and controlling displays. Great care
has been taken to design products that will satisfy a wide variety of installations.
Some of the design goals of these systems include the following:

• Easy transfer of messages

• The ability to tell a display or group of displays in the network which

message should run

• The ability to determine the status of any display on the network

• The ability to control multiple display technologies on the same network

performance, reliability, easy maintenance, and long life. A light sensor on the front
of the primary display is used for automatic dimming of the LEDs based on the
ambient light levels.

The Daktronics AF-3300 display contains two separate LED matrices. The pixels
have either a 12 mm or a 20 mm center-to-center spacing, and are lit using LEDs
(light emitting diodes). Although the matrices are different sizes and have different
color capacities, a single controller provides signal to the display.

through the displays.

1.4 Component Identification

The following illustrations depict some of the more commonly accessed Galaxy®
display components.

This is only a brief overview. Refer to Section 4 for additional information on
maintaining the various display components.

Controller: The display’s controller is the “brains” of the display (refer to
The controller receives, translates, and activates the signal information from the
computer to the appropriate pixels on the display.

Figure 2).

1-4

Figure 2: Version 3 Controller

Display Address: The display address is an identification number assigned to each
display of a network. Rotating the address switches on the controller sets the display
address. The control software uses the address to locate and communicate with each
display. Displays that are on the same network cannot have the same address.

Driver/Pixel Board: For the 20 mm pixel boards, the LEDs are mounted directly
onto the driver/pixel board. In the case of the 12 mm boards, there is a separate LED
board and a separate driver that attaches to it. The driver board, whet her separate or
built-in, is responsible for the switching and intensity levels of the LEDs.

Galaxy

matrix displays.

LED (light emitting diode): This is a low energy, high intensity lighting unit.

Introduction

Louver: Black plastic shade positioned horizontally above each pixel row. The
louvers increase the level of contrast on the display face and direct LED light.

Mirror: A mirror display is the second display in a Primary-Mirror or Double-Face
configuration. The mirror display does not have a controller. All signal information
to the mirror is received though a signal interconnect cable from the primary.

Module: There are two types of modules in the AF-3300, 12 mm RGB and 20 mm
monochrome red. Each is individually removable from the front of the display.

Module Latch Assembly: This is a device utilizing a sliding retainer bar to hold the
module firmly to the display frame. There are two latches on the 12 mm modules
(refer to

Figure 3) and four latches on the 20 mm modules (refer to Figure 4). A

Hex wrench is used to turn the different latches.

Network: A network consists of multiple displays connected to each other. Up to
240 primary displays can exist on one network.

Pixel: A pixel is a single LED or cluster of LEDs. The number and color of the
LEDs depends on display application.

Power Supply: Converts AC line voltage from the load center to low DC voltage for
one or more module driver boards.

Primary: A primary display is a signal-faced unit or the first display in a Primary­Mirror or Double-Face configuration. The communication and temperature sensor
input will be connected to this display. The light sensor is also internally mounted in
this display. An interconnect cable will transfer information from the primary to the
mirror display in the Double-Face configuration.

1.5 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
also useful when trying to communicate maintenance or troubleshooting efforts.

Figure 5: Module Numbering for Reference

A module is the building block of the Galaxy
24 pixels high by 16 pixels wide and the 20 mm modul es m easure 16 pixels high by
16 pixels wide. By placing modules side-by-side and on top of one another, a display
of any size can be designed and built. Individual modules can be easily removed

In addition, the following labeling formats might be
found on various Daktronics drawings:

• “TB_ _” signifies a termination block for

power or signal cable

• “F_ _” represents a fuse

• “E_ _” shows a grounding point

• “J_ _” denotes a power or signal jack

• “P_ _” stands for 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:

• “0P-_ _ _ _-_ _ _ _” indicates an individual

circuit board, such as the internal fiberboard

• “0A-_ _ _ _-_ _ _ _” stands for an assembly,

such as a circuit board and the plate or bracket
to which it is mounted

• “W-_ _ _ _” represents a wire or cable

Note: A collection of circuit boards working as a single unit may carry an assembly
label. Cables may also carry the assembly numbering format in certain
circumstances. This is especially true of ribbon cables.
