Page 9: Introduction
• Appendix B contains information on the signal converter. Daktronics identifies manuals by an ED number located on the cover page of each manual. For example, Daktronics refers to this manual as ED-13620. Daktronics, commonly uses a number of drawing types, along with the information that each provides. -
Page 10: Network Concepts
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. -

Page 13: Figure 2: Controller
® Galaxy : Daktronics trademarked name for LED monochrome or tri-colored matrix signs. Jumper: A jumper is a metal bridge that closes an electrical circuit. In most cases, it consists of a black plastic plug (with metal wires inside) that fits over a pair of protruding pins. -
Page 14: Figure 3: 68Mm Amber Galaxy Module
Modem: This is the general term given to both the sending and receiving device. The sending modem can be either internal or external to the computer. Another modem must be used at the display to receive the signal and transfer it to the display’s controller. -
Page 15: Daktronics Nomenclature
Daktronics numbers modules on a Galaxy sign. Figure 6 on the right breaks down the module numbering method. In addition, various Daktronics drawings may contain the following labeling formats: • “TB_ _” represents a termination block for power or signal cable •... -
Page 16: Figure 7: Typical Label
Finally, drawings commonly have Daktronics part numbers. You can use those part numbers when requesting replacement parts from Daktronics Customer Service. Take note of the following part number formats: • “0P-_ _ _ _-_ _ _ _” denotes an individual circuit board, such as a line receiver. -
Page 17: Mechanical Installation
Section 2: Mechanical Installation Note: Daktronics does not guarantee the warranty in situations where the sign is not constantly in a stable environment. Daktronics engineering staff must approve any changes that may affect the weather-tightness of the sign. If you make any modifications, you must submit detailed drawings of the changes to Daktronics for evaluation and approval, or you may void the warranty. -

Ventilation Requirements Reference Drawings: Shop Drawing; AF-3080-24x***-68B......Drawing B-163291 Shop Drawing; AF-3080-8/16x***-68B......Drawing B-163293 Fans, mounted in the back sheets toward the top of the display, allow for ventilation. Maintain a minimum distance of 3" (7.62 cm) below the sign to maintain proper airflow. -
Page 19: Sign Mounting
The customer must have a qualified structural engineer review the number of attachment points needed and the wall structure to ensure both meet all national and local codes. Daktronics recommends using all clip angles as attachment points. Carefully uncrate the sign. Look each side of the sign over for damage during shipping. -
Page 20: Optional Temperature Sensor Mounting
Optional Temperature Sensor Mounting The temperature sensor mounts separately and requires a location away from the influence of chimneys, air conditioners, vents, tar roofs, concrete, and parking lots, which can cause abnormal temperature fluctuations. Usually, a separation of at least 20-30 feet horizontally and 8 feet vertically is required to achieve this. -
Page 21: Figure 11: Temperature Board/Temperature Sensor Enclosure
Use a two pair, individually shielded cable (Belden 5594, Daktronics part number W-1234) to connect the sensor to the display controller. Maximum length is 1000 feet. Follow these steps to mount the temperature sensor: Run ½" conduit from the sensor location to the controller where the sensor cable is to be attached. - Page 23 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 24 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...

Page 25: Electrical Installation
Only a qualified individual should terminate power and signal cable within this Daktronics sign. The Daktronics engineering staff must approve any changes made to the sign. Before altering the sign, submit detailed drawings for the proposed modifications to the Daktronics engineering staff for evaluation and approval or you will render the warranty null and void. -
Page 26: Control Cable Requirements
RS232 This cable is a 2-conductor shielded cable used to transmit an RS232 signal (Daktronics part number W-1117). This shielded cable should not be subjected to mechanical flexing after installation. This cable is not for direct burial and should be routed in a dedicated, grounded metallic conduit at the base of the sign structure. -
Page 27: Modem
Fiber Optic This cable is a 4-fiber cable (Daktronics part number W-1376). Two fibers are used for display communications and the other two are saved for spares. The cable may be either direct burial or routed in conduit but should not be subjected to mechanical flexing. -

Refer to Shop Drawings for approximate locations of power and signal conduit. You must use separate conduit to route: • Power •... -
Page 29: Power
Refer to drawings for voltage and current requirements for your sign size. Each uses a 120/240VAC single-phase or 120/208 three-phase power source. Do not connect the signs to any voltage other than that listed on the Daktronics product label. Proper power installation is imperative for proper display operation. The following sub-sections give details of display power installation. -
Page 30: Figure 21: Grounding
Article 250 of the National Electric Code may be used. Daktronics recommends that the resistance to ground be 10 ohms or less. If the resistance to ground is higher than 10 ohms, it will be necessary to install additional grounding electrodes to reduce the resistance. -
Page 31: Power Installation
Power Installation There are two considerations for power installation: installation with ground and neutral conductors provided, and installation with only a neutral conductor provided. These two power installations differ slightly, as described in the following paragraphs: Ins allation w th Ground and Neutral Conductors Provided For this type of installation, the power cable must contain an isolated earth-ground conductor. -
Page 32: Main Disconnect
Ins allation w th Only a Neutral Conductor Provided Installations where no grounding conductor is provided must comply with article 250-32 of the National Electrical Code. If the installation in question meets all of the requirements of article 250-32, the following guidelines must be observed: •... -

One end of the signal cable should be terminated to the 6-position terminal block in the display labeled “RS422 IN” (TB2). The opposite end is terminated at the signal converter (Daktronics part number 0A-1127-0237) in the control room. Figure 25: RS422 Layout Note: RS422 cable must be installed so that it is separated from any source of electrical interface. -
Page 35: Modem
Fiber Optic When the fiber optic cables are used, signal from the converter enters the fiber board (J4/J5). An adapter module (Daktronics part number 0A-1146-0029) allows the use of a 6-conudctor-phone cord with RJ11 connectors (par number 0A-1137-0160) to relay the signal to J1 (RS232 IN) on the controller. -
