Page 7: Introduction
• Appendix C provided information on the optional temperature sensor. Daktronics identifies manuals by an ED number located on the cover page of each manual. For example, this manual would be referred to as ED-14212. Listed below are a number of drawing types commonly used by Daktronics, along with the information that each is likely to provide. -
Page 8: Safety Precautions
Figure 1 below illustrates the Daktronics drawing label. The drawing number is located in the lower-right corner of the drawing. Listing the last set of digits and the letter preceding them identifies drawings in the manual. In the example below, the drawing would be referred to as Drawing B-181287. -
Page 9: Network Concepts
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. -

Shop Drawing, AF-3112-2480-34-SF-*-P/M....Drawing A-193720 Shop Drawing, AF-3112-1680-34-SF-*-P/M....Drawing A-201993 ® Daktronics AF-3112 Galaxy displays are designed and manufactured for performance, reliability, easy maintenance, and long life. The pixels have a 34mm center-to-center spacing and are illuminated using LEDs (light-emitting diodes). A light sensor on the front of the display is used for automatic dimming of the LEDs based on the ambient light levels. -
Page 11: Component Identification
Component Identification ® The following illustrations depict some of the more commonly accessed Galaxy display components. Because Daktronics occasionally alters standard design to meet customer needs, the actual display design may vary slightly from the illustrations below. This is only a brief overview. Refer to Section 4 for additional information on maintaining the various display components. -
Page 12: Figure 3: 34Mm Module
Signal Converter: The signal converter, shown in Figure 4 on the right, is a Daktronics supplied unit that converts the data from RS232 to RS422 or RS232 to fiber optic signal. The signal converter is connected to the control PC via straight through serial cable. -
Page 13: Daktronics Nomenclature
Daktronics Nomenclature Figure 5: Numbering Example - 24x80 Front 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. - Page 14 • “W-_ _ _ _” represents a wire or cable. Cables may also carry the assembly numbering format in certain circumstances. This is especially true of ribbon cables. Most circuit boards and components within this display carry a label that lists the part number of the unit.

Page 15: Mechanical Installation
Section 2: Mechanical Installation Note: Daktronics does not guarantee the warranty in situations where the display is not constantly in a stable environment. Daktronics engineering staff must approve any changes that may affect the weather-tightness of the display. If any modifications are made, detailed drawings of the changes must be submitted to Daktronics for evaluation and approval, or the warranty may be void. -
Page 16: Ventilation Requirements
There are nutserts provided on the back of the display for mounting of the display to a structure. Use all the provided mounting nutserts when mounting the display. If a mounting kit was ordered with the display, mount the channel to the display using the nutserts on the back of the display. -
Page 17: Display Mounting
Refer to Drawing A-193720 or A-201993 for a suggested wall mount method. The number of attachment points needed and the wall structure must be reviewed by a qualified structural engineer and meet all national and local codes. Daktronics recommends attaching to all nutserts provided. - Page 19 Eyebolts Almost every display that leaves Daktronics is equipped with eyebolts for lifting the display. There are two standard sizes of eyebolts: ½″ and A″. Load Increase Factor: The load increases as the lift angle (θ) decreases. The allowable load on the eyebolts also decreases with the lift angle due the bending stress on the eyebolts.
- Page 20 F. Eyebolts should never be painted or otherwise coated when used for lifting. Such coatings may cover potential flaws in the eyebolt. G. To attain the safe working loads listed for regular eyebolts, 90% of the thread length must be engaged. Copyright 1996-2001 ED-7244 Daktronics, Inc. Rev. 4 – 14 March 2001...
