Daktronics builds displays for long life and that require little maintenance. However, from time to time, certain sign components need replacing. The Replacement Parts List in Section 4.14 provides the names and numbers of components that you may need to order during the life of the sign. Most sign components have a white label that lists the part number. The component part number is in the following format: 0P-_ _ _ _-_ _ _ _ (component) 0A-_ _ _ _-_ _ _ _ (multi-component assembly).

Following the Replacement Parts List is the Daktronics Exchange and Repair and Return Programs in Section 4.15. Refer to these instructions if any sign component needs replacement or repair.

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 installatio ns 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 me ssages

• The ability to tell a display or group of displays in the net work 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

1-2

Introduction

Page 11

Tools required for mounting the display depend on the location and size of the display. For some installations, it may be possib le to use pre-terminated telephone cables with the displays.

There are five (5) network systems available: RS232, RS422, modem, fiber, and radio. Up to 240 displays can exist one network.

RS232 Network

RS232 (EIA/TIA-232-E) is a standard communication interface that employs a single-ended serial transmission scheme that uses a maximum cable length of 8 meters (25 Feet). This interface was designed for computer communication at short distances. Most computers have an RS232 communication port.

RS422 Network

RS422 (EIA/TIA-422-B) is a standard communication interface that utilizes a differential balanced transmission scheme that uses a typical maximum cable length of 1.2 km (approximately 4000 feet). The main advantage of RS422 over RS232 is the longer cable length that is possible. A signal converter is needed to convert the computer’s RS232 to RS422.

Modem Network

The modem is a standard communication interface that utilizes standard phone transmission lines. The phone company assigns each phone line a number that the modem uses to communicate between controller and display.

Fiber Optic Network

A fiber optic network is a standard communication method transmitting light (signal) through a glass fiber. Fiber optic cable has a maximum length of 2,000 feet. A signal converter is needed to convert the computer’s RS232 signal to fiber optic signal; a minimum of two fibers is required.

Radio Network

The Radio network is a standard communication method that uses radio waves at high frequencies to transmit signal. The Venus 1500 Radio network has a maximum length of 1500 feet. A nearly straight line-of-sight path must be maintained between the Server Radio connected to the computer and the Client Radio connected to the display. Refer to Section 3 and ED-13348 for additional information.

Daktronics designs and manufactures AF-3080 Galaxy signs for performance, reliability, easy maintenance, and long life. The pixels have a 68 mm center-to-center spacing and LEDs (light emitting diodes). Each sign section has minimum 18-inch character height. An optional remotely mounted light sensor can automatically dim the LEDs based on the ambient light levels. The configuration of pixels depends on the model of sign ordered.

Figure 5: Module Numbering Example – 24x80 Front

To fully understand some Daktronics drawings, such as schematics, it is necessary to know how those drawings label various components. This information is also useful when trying to communicate maintenance or troubleshooting efforts.

A module is the building block of the Galaxy sign. Each module measures 4 pixels high by 4 pixels wide. By placing modules side-by-side and on top of one another, Daktronics can design and build signs of any size. A person can easily remove individual modules

Figure 6: Module Numbering

from the sign if required. Figure 5 above illustrates how Daktronics numbers modules on a Galaxy sign. Figure 6 on the right breaks down the module numbering me t ho d.

In addition, various Daktronics drawings may contain the following labeling formats:

• “TB_ _” represents a termination block for power or signal cable

• “F_ _” denotes a fuse

• “E_ _” signifies a grounding point

• “J_ _” indicates a power or signal jack

• “P_ _” shows a power or signal plug for the opposite jack

Introduction

1-7

Page 16

Finally, drawings commonly have Daktr onics part numbers. You can use those p art 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.

• “0A-_ _ _ _-_ _ _ _” indicates an assembly, such as a circuit board and the

plate or bracket to which it mounts. A collection of circuit boards working as a single unit may also carry an assembly label.

• “W-_ _ _ _” represents a wire or cable. Cables may also carry the assembly

numbering format in certain circumstances. This is especially true of ribbon cables.

• “F-_ _ _ _"stands for a fuse.

Most circuit boards and components within this sign carry a label that lists the part number of the unit. If the Replacement Parts List in Section 4.12 does not list a circuit board or assembly, use the label to order a replacement. Figure 7 below illustrates a typical label. The part number is in bold.

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 a pprove 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 eval uation and approval, or you may void t he warranty.

Daktronics is not responsible for installations or the structural integrity of support structures done by others. The customer is responsible to ensure a qualified structural

engineer approves the structure and any additional hardware.

2.1 Mechanical Installation Overview

Because every installation site is unique, Daktronics has no single procedure for mounting Galaxy signs. This section c ontains gener al information only and may or may not be appropriate for your particular installation.

A qualified installer must make all decisions regarding the mounting of this sign.

Read both the mechanical and electrical installation sections of this manual before beginning any installation procedures.

2.2 Support Structure Design

Support structure design depends on the mounting methods, sign size, and weight. The structure design is critical; only a qualified individual should mount the sign. Sign height and wind loading are also critical factors. It is the customer’s responsibility to ensure that the structure and mounting hardware are adequate.

Daktronics is not responsible for the installations or the structural integrity of support structures done by others.

The installer is responsible to ensure the mounting structure and hardware are capable of supporting the sign and agrees w ith local codes.

Before beginning the installation process, verify the following:

• The mounting structure provides a straight and square frame for the sign.

• The mounting structure supports the sign without yielding at any

unsupported points after mounting.

• Clearance: 3 " of unobstructed space is available below the sign for

ventilation. 1¼" of unobstructed space is available above the top of the sign.

Correct any deficiencies before installation.

Mechanical Installation

2-1

Page 18

2.3 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. Refer to the appropriate Shop Drawing for additional information.

If the sign cabinet is completely enclosed:

• Provide 6 square inches of unobstructed opening per module to ensure

adequate cooling.

• Make allowances to compensate for the percentage of material covering the

openings in the structure.

• For adequate cooling, the cabinet may require forced ventilation. If the

enclosed cabinet must use forced ventilation, it must ventilate at a rate of 10 cubic feet per minute per module (10.64" x 10.64" active area).

Failure to comply with these requirements voids the Galaxy sign warranty.

2.4 Lifting the Sign

The top of the sign has eyebolts to lift the unit. Do not exceed the rated load of the eyebolts. Refer to the information at the end of this sectio n labeled Eyebolts to determine the allowable load of the eyebolts shipped with the sign.

Figure 8 on the right illustrates both the correct (left example) and the incorrect (right example) method of lifting a sign. Lift the sign as shown on the left, with the lifting bar. Use every lifting point provided.

Do not attempt to permanently support the sign by the eyebolts.

If you remove the eyebolts, adequately seal the holes using 13 bolts and sealing washers, ½ inch i n siz e. Be sure to silicone along the threads to ensure water does not enter the sign.

2.5 Sign Mounting

Reference Drawings:

Shop Drawing; AF-3080-24x***-68B............................Drawing B-163291

Shop Drawing; AF-3080-8/16x***-68B.........................Drawing B-163293

The method used to mount signs varies greatly fro m location to location. For this reason, the manual covers only general mounting topics.

The installer is responsible to ensure the installation will adequately meet local codes and standards. The installer is also responsible for the mounting method and hardware.

Before beginning the installation process, verify the following items:

• The mounting structure will provide a straight and square frame for the

sign. Height variation in any four-foot horizontal section may not exceed ¼inch.

• The mounting structure will not give way at any unsupported points after

the sign is mounted.

The back of the sign uses 2x2x1/4" steel clip angles at the locations shown in Drawing B-163291 and Drawing B-163293 These angles assist in mounting the sign. Remember to have all mounted signs inspected by a qualified structural engineer.

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.

1. Carefully uncrate the sign. Look each side of the sign over for damage

during shipping.

2. Following the guidelines described in Section 2.4 , lift the sign into p osition

on the support structure using all provided eyebolts.

3. Weld or use ½" Grade-5 bolts and hardware to secure the clip angles to the support structure as shown in Top View in Drawing B-163291 and

Drawing B-163293.

4. Refer to Section 3 for information on routing power and signal.

5. Upon completing the installation, carefully inspect the sign for any holes

that may allow water to seep into the sign. Seal any openings with silicone. If you remove the eyebolts on the top of the sign, plug the holes with bolts and the rubber sealing washers that you removed with the eyebolts. Silicone the threads on the bolts.

2.6 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. Locations where air movement is restricted are also unsatisfactory. Refer to Drawing A-79767.

The ideal sensor location is a north eaves or a northern exposure, above grass and away from direct sunlight. This location gives extra stability and accuracy to the sensor because of the added shading usually obtained on a northern exposure. See Figure 9 on the right for details.

The second choice for locating a temperature sensor is on the display itself, or somewhere on the display structure. A light-colored display is preferred in this application. Location of the sensor should be above, below, or on a northern edge of the display to keep the sensor shaded. If mounting above the display, a minimum height of 6 feet is required. If mounting below the display, a minimum of 8 feet above ground and a minimum of 1 foot between the sensor and the display are required, as seen in Figure 10 below.

Greater accuracy is obtained if grass is below the sign rather than concrete or some other material.

Figure 9: Temperature Sensor Eave/Wall Mount

Mechanical Installation

Page 21

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:

1. Run ½" conduit from the sensor location to the controller where the sensor cable is to be attached. The cable must be routed through ½" metal conduit, which should be earth grounded to protect the sensor and controller from lightning damage.

2. Power down the controller when the sensor cable is being attached.

3. Connect the cable to the temperature sensor terminal block as shown below. Refer to Drawing A-79410 for the location of the terminals.

Figure 11: Temperature Board/Temperature Sensor Enclosure

4. Install the mesh screen with the four screws enclosed.

5. Connect the cable to the display controller as described in the controller

installation manual. Start operation of the controller.

Eyebolts

Almost every display that leav es D ak tronics is equipped w ith ey ebolts 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. In sum, the smaller the angle between the cable and the top of the display, the lighter the sign must be to safely lift it. Do

NOT attempt to lift the display when the lift angle is less than 30 degrees.

A. Do not use eyebolts on angular lifts unless absolutely necessary. For angular lifts, the shoulder pattern

eyebolt is preferred.

B. Load should always be applied to eyebolts in the plane of the eye, not at some angle to this plane.

C. Shoulder eyebolts must be properly seated (should bear firmly against the mating part), otherwise the

working loads must be reduced to those indicated for regular eyebolts. A washer or spacer may be required to put the plane of the eye in the direction of the load when the shoulder is seated.

D. No load greater than the safe working load listed in the data table should be used.

E. To obtain the greatest strength from the eyebolt, it must fit reasonably tight in its mounting hole to prevent

accidental unscrewing due to twist of cable.

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.

Section 3: 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 alter i ng the sign, submit detailed drawings for the proposed modifications to the Daktronics engineeri ng staff for e valuation a nd approval or you will render the warr anty null and void.

3.1 Common Connectors in the Sign

The power and signal connections in the signs use many different types of connectors. Take special care when disengaging any connector so as not to damage the connector, the cable, or the circuit board.

When pulling a connector plug from a jack, do not pull on the wire or cable; pull on the jack itself. Pulling on the wires may damage the connector.

The following information presents some common connectors encountered during sign installation and maintenance:

1. Ribbon Cable Connectors: Figure 12 on the upper right illustrates a typical ribbon

connector. To disconnect the ribbon cable, push the metal clips on the sides to unlock and remove the jack.

Before replacing a ribbon cable connector, spray it with DeoxIT may cause signal problems. In addition, apply a generous amount of CaiLube

™

contact cleaner to remove any foreign matter that

™

protector paste in the plug before inserting it into the jack. This paste protects both the plug and the jack from corrosion.

2. Termination Blocks:

Termination blocks connect internal power and signal wires to wires of the same type coming into the sign from an external source. Most signal wires come with forked connectors crimped to the ends of the wire. Power wires need to have one-half inch of insulation stripped from the end of the wire prior to termination. Tighten all screws firmly to ensure a good electrical connection. Refer to the right for Figure 13.

3. Phoenix

-Style Connectors:

Phoenix-style connectors, usually green, allow for signal termination on circuit boards. Refer to Figure 14 on the right. 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 connectors grip on the wire. To insert a wire, push the bare wire into the connector and turn the above screw clockwise to lock the wire into place.

4. Mate-n-Lok

Connectors:

The white Mate-n-Lok connectors found in the signs come in a variety of sizes. Figure 15 on the right illustrates a five-pin Mate-n-Lok connector. To remove the plug from the jack, squeeze the plastic locking clasps on the side of the plug and pull it from the jack.

5. Fiber Optic Connectors:

A fiber optic cable has a “twist-on” connector at each end. To remove the fiber plug, push it toward the board and twist it counter-clockwise until you can pull the plug from the jack. Figure 16 on the right shows this connector.

6. Phone Jacks (RJ11 Connectors): RJ connectors, as seen on the lower right in Figure 17, are similar to the telephone connectors found in

homes. In order to remove this plug from the jack, depress the small clip on the underside of the plug.

Before replacing an RJ connector, spray it with DeoxIT contact cleaner to remove any foreign matter that may cause signal problems. In addition, apply a generous amount of CaiLube

™

protector paste in the plug before inserting it into the jack. This paste will protect both the plug and the jack from corrosion.

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. This cable has a maximum length of 25 feet.

RS422

This cable is a 6-conductor shielded cable used to transmit an RS422 signal (Daktronics part number W-1210). This shielded cable consists of unpaired wires. They should not be subjected to mechanical flexing after installation. This cable is not for direct burial and should have one of the following routings:

• In dedicated metallic conduit

• Inside buildings-if cable is not in conduit, keep away from interface signals

With interface signals, (such as power conductors, intercom, etc.) typically a twofoot separation is required. The maximum length of an RS422 signal cable is 4,000 feet (1.22 km).

Electrical Installation

Page 27

Modem

The modem option will use standard telephone cable routed through a conduit. The local telephone company will need to assist in this installation.

Ask the telephone company which colors are used by the TIP and the RING for signal hook up.

Note: The telephone lines must be dedicated lines and not run through a switchboard system.

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. The maximum length of a fiber optic cable is 2,000 feet (611.6 meters).

Radio

The Server radio connected to the computer requires a six-conductor 18 AWG cable to be wired from the J-box converter to the Outdoor Server. This wire needs to be in conduit when exposed to outdoor conditions. The maximum distance from the J-box to the Server radio is 1000 feet (611.6 meters).

The Client radio at the display comes with cable that is rated for outdoor use and does not need to be in conduit.

3.3 RJ Connector Cables

The connector used for RS232 input to the display is an industry standard, 6-pin RJ11. This connector can be found on many telephones and LANs.

The cable used in the network is a standard flat sixconductor telephone cable (standard flipped cable). Refer to Figure 18 on the right. This cable has one end that is the mirror image of the other end (i.e., the cable is flipped). Refer to Figure 19 below for a standard flipped cable.

Notice in Figure 19, at the bottom, that the color code on one connector must be made the opposite on the other connector. When installing a network, it is not easy to remember in which direction the previous end was oriented. One simple way to avoid confusion is to standardize the color code, having one color for the connector going into the output of a sign, and the opposite color for a connector going into the input of a sign. This will help ensure correct cabling since cables are always installed from the output jack of one sign to the input jack of the next sign.

Installing an RJ Connector

Installing an RJ connector on the end of the conductor cable is a simple task when the correct tools are used. The RJ crimping tool (Daktronics part number TH-1033) performs two separate steps.

First, use the crimping tool to strip the outer insulation from the inner wires. This does not result in bare wires since only the gray outer jacket is removed. After correct stripping, the wire will appear as shown in Figure 20 on the right.

The crimping tool is then used to crimp the RJ connector onto the cable. The RJ connector is locked into a special socket in the tool. The stripped wire is inserted into the RJ connector. Finally, the tool is squeezed like pliers to crimp the connector onto the wire. This completes the installation of an RJ connector onto the wire.

Daktronics does not incl ude the cond uit. Refer to Shop Drawings for approximate locations of power and signal conduit. Y ou must use separate cond uit to route:

• Power

• Signal IN wires

• Signal OUT wires (if another sign requires signal)

Locate the conduit holes at the bottom right (rear view) of the back of the sign (refer to the Shop Drawings).

Punch or drill out the desired conduit openings. Be careful not to damage any internal components. Attach the conduit, and route the power and signal cables. Refer to Drawing B-163291and Drawing B-163293 for a picture of the power and signal termination panels.

For signs with more than one face, signal and temperature sensor wiring between signs can rout e through the same conduit .

Refer to drawings for vo l tage 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. Electrical installations must be performed by qualified personnel. Unqualified personnel should not attempt to install the electrical equipment. Serious danger to equipment and personnel could occur if equipment is improperly installed.

Grounding

Displays must be grounded according to the provisions outlined in Article 250 of the National Electrical Code ohms or less. Verification of ground resistance can be performed by the electrical contractor who is performing the electrical installation. Daktronics Sales and Service personnel can also perform this service.

The display system must be connected to earth-ground. Proper grounding is necessary for reliable equipment operation. It also protects the equipment from damaging el ectrical disturbances and lightni ng. The display must be properly grounded or the warranty will be void.

Electrical Installation

. Daktronics recommends a resistance to ground of 10

3-5

Page 30

Figure 21: Grounding

A minimum of one grounding electrode must be installed for each display face. The grounding electrode is typically one grounding rod for each display face. Other grounding electrodes as described in 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. The grounding electrode should be installed within 25 feet of the base of the display. The grounding electrode must be connected to the ground terminal in the display panel board.

This grounding electrode must be installed in addition to the equipment-grounding conductor that should be part of the power installation. The material of an earthground electrode differs from region to region and from conditions present at the site. The support structure of the display cannot be used as an earth ground electrode. The support is generally embedded in concrete, and if in earth, the steel is either primed or it corrodes, making it a poor ground. The grounding system and grounding electrodes must be installed according to Article 250 of the National Electrical Code and any applicable local codes.

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 Providedt i

For this type of installation, the power cable must contain an isolated earth-ground conductor. Under this circumstance, do not connect neutral to ground at the disconnect or at the display. This would violate electrical codes and void the warranty. Use a disconnect so that all hot lines and neutral can be disconnected. Refer to Figure 22 below for installation details. The National Electrical Code requires the use of a lockable power disconnect within sight of or at the display.

Figure 22: Installation with Ground and Neutral Conductor Provided

Electrical Installation

3-7

Page 32

Ins allation w th Only a Neutral Conductor Provided t i

Installations where no grounding conductor is provided must comply with arti cle 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:

• Connect the grounding electrode cable at the local disconnect, never at the

display panel board.

• A disconnect that opens all of the ungrounded phase conductors should be

used.

• The neutral and the ground conductors should be bonded in the display

panel board.

Refer to Figure 23 below for installation details.

Figure 23: Installation with only Neutral Conductor Provided

3.7 Main Disconnect

The National Electrical Code requires the use of a lockable power disconnect near the sign. Provide a lockable disconnect switch (knife switch) at the sign location so that all power lines can be completely disconnected. Use a 3-conductor disconnect to disconnect both hot lines and the neutral. Mount the main disconnect at or near the point of power supply connection to the sign. Provide a main disconnect for each supply circuit to the sign.

You must locate the means of disconnection in a direct line of sight from the sign 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 sign.

Exception: You may locate the disconnecting means that are capable of being locked in the open position elsewhere.
