Page 7: Introduction
• Appendix B includes 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-15507. 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
Reference Drawing: Shop Dwg, AF-3300-48x34-12-RGB, 32x80-20-R ..Drawing B-222544 Daktronics displays are built for long life and require little maintenance. However, from time to time, certain display components will need replacing. The Replacement Parts List in Section 4.12 provides the names and numbers of components that may need to be ordered during the life of the display. -
Page 9: 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. -

LEDs. ® Galaxy : Daktronics trademarked name for LED monochrome, tri-colored, or RGB matrix displays. LED (light emitting diode): This is a low energy, high intensity lighting unit. Introduction... -
Page 11: Figure 3: 12 Mm 2-Point Latches
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. -
Page 12: Daktronics Nomenclature
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 ®... - Page 13 Most circuit boards and components within this display carry a label that lists the part number of the unit. If a circuit board or assembly is not listed in the Replacement Parts List in Section 4, use the label to order a replacement. A typical label is shown in .

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
Note: No clearance is required once the eyebolt is removed. Correct any deficiencies before installation. Ventilation Requirements Reference Drawing: Shop Dwg, AF-3300-48x48-12-RGB, 32x48-20-R ..Drawing B-241264 Shop Dwg, AF-3300-48x64-12-RGB, 32x80-20-R ..Drawing B-240560 Vents are provided in the face of the display for ventilation. Vents and fans draw air into the display at the bottom, and the warm air is expelled out at the top through vents in the front. -

Display Mounting Reference Drawing: Shop Dwg, AF-3300-48x48-12-RGB, 32x48-20-R ..Drawing B-241264 Shop Dwg, AF-3300-48x64-12-RGB, 32x80-20-R ..Drawing B-240560 The method used to mount displays can vary greatly from location to location. For this reason, only general mounting topics can be addressed in this manual. It is the responsibility of the installer to ensure the installation will adequately meet local codes and standards, as well as the mounting hardware and method. -
Page 19: Electrical Installation
The Daktronics engineering staff must approve any changes made to the display. Before altering the display, submit detailed drawings for the proposed modifications to the Daktronics engineering staff for evaluation and approval or the warranty will be rendered null and void. -
Page 20: Figure 11: Phoenix Connector
™ 3. Phoenix -Style Connectors: Phoenix-style connectors, which are usually green, are often used for signal termination on circuit boards. Refer to Figure . Strip one-quarter inch of insulation from the wire prior to termination. To remove a wire, turn the above screw counter- clockwise to loosen the connector's grip on the wire. -
Page 21: Conduit
Conduit Daktronics does not include the conduit. Separate conduit must be used to route: • Power • Signal IN wires to the signal termination enclosure, when applicable • Signal OUT wires (if not using the provided interconnect cable) The power J-box is provided with ¾” threaded holes for use with ¾” conduit. -
Page 22: 3.4 Power
Displays must be grounded according to the provisions outlined in Article 250 of the ® National Electrical Code . Daktronics requires a resistance to ground of 10 ohms or less. The display system must be connected to earth-ground. Proper grounding is necessary for reliable equipment operation. -
Page 23: Power Installation
Article 250 of the National Electric Code may be used. Daktronics requires 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 24: Main Disconnect
Note the following colors are used for the pre-terminated wires: • Line 1 – Black • Neutral - White • Grounding Conductor - (Green-Yellow) If these power terminations cannot be made at the enclosure, they can be made directly to the power termination panel in the display. The following steps need to be done to complete internal connections: Open the display as explained in Section 4.4 and locate the power termination panel for these displays. -
Page 25: Signal Termination From Computer To Display
The disconnecting means must be located in a direct line of sight from the display or outline lighting that it controls. This requirement provides protection by enabling a worker to keep the disconnecting means within view while working on the display. Exception: Disconnecting means that are capable of being locked in the open position may be located elsewhere. -
Page 26: Signal Termination Between Displays (Primary - Mirror)
Signal Termination Between Displays (Primary – Mirror) Most displays are shipped as either a single Primary display or two displays in a 2V, Primary-Mirror configuration. The Primary - Mirror (2V) quick connect cable is used to terminate signal between two displays. The six-foot cable goes from the Signal OUT (J34) on the primary display to Signal IN (J32) on the mirror display. -

Page 32: Controller
Controller Reference Drawings: CNTRLR II, Galaxy, 8 Conn, J1087 ......Drawing B-204771 The controller sends data to the modules. Refer to the signal summary in Section 4.2 for more information and for the possible location of the controller board. Figure 23 illustrates a typical controller. - Page 33 The rotary switches set the hardware address, which the software uses to identify that particular display. When replacing a controller board, be sure to set the rotary switches in the same address configuration as the defective controller. Each controller in a network needs a unique address. Note: Setting both rotary switches to address 0 (set the switches to 0 by rotating them counter clockwise until the arrow points to 0) can activate a test mode.
