Introduction

1.3 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

ntrolling a group of displays from a central control point. Daktronics responded by

co 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 system

• 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

There are five (5) network systems available: RS232, RS422, modem, fiber, and

adio. Up to 240 displays can exist on 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 7.6 meters (approximately 25 feet). This interface was designed for computer communication at short distances. A computer with a serial, RS232 communication port is required. Refer to Section 3 for additional information.

s include the following:

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 4,000 feet). The main advantage to RS422 over RS232 is the longer cable length that is possible. A signal converter is needed to convert the computer’s RS232 serial signal to RS422. Refer to Section 3 for additional information.

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 at the computer uses to communicate to the modem in the display. Refer to Section 3 for additional information.

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 600 meters (approximately 2,000 feet). A signal converter is needed to convert the computer’s RS232 serial signal to fiber optic signal; a minimum of two fibers is required. Refer to Section 3 for additional information.

Introduction

1-3

Radio Network

The Radio network is a standard communication method that uses radio waves at high frequencies to transmit signal. The Venus distance of 450 meters (approximately 1,500 feet) outdoor and 150 meters (approximately 500 feet) indoor. A nearly straight line-of-sight path must be maintained between the Server Radio attached to the building and the Client Radio connected to the display. A computer with a serial, RS232 communication port is required. Refer to Section 3 and the Venus 1500 Gen 2 Radi o m a nual , ED13932, for additional information.

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.

3: Section Electrical Installation

Only a qualified individual should terminate power and signal cable within this Daktronics display.

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.

3.1 Common Connectors in the Display

The power and signal connections in the displays use many different types of connectors. Tak e special care when disengaging any connector to prevent damage to the connector, cable, or 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 display installation and maintenance.

1. Ribbon Cable Connectors:

Figure 9 on the right illustrates a typical ribbon connector. To

disconnect the ribbon cable, push the plastic clips on the sides out 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 to the plug before inserting it into the jack. This paste will protect both the plug and the jack from corrosion.

2. Termination Blocks:

Termination blocks are usually used to connect internal power and signal wires to wires of the same type coming into the display from an external source. 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

3. Phoenix

™

-Style Connectors:

Figure 10 on the right.

Phoenix-style connectors, which are usually green, are often used for signal termination on circuit boards . R e fer to

on the right. Strip one-quarter inch of insulation from the

Figure

wire prior to termination. To remove a wire, turn the above screw counter-clockwise to loosen the connector's 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 Mate-n-Lok connectors found in the displays are

white and come in a variety of sizes.

Figure 12 on the right

illustrates a four-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. Phone Jacks (RJ Connectors):

RJ11 or RJ45 connectors, as seen in

Figure 13 on the lower

right, are similar to those on telephone and LAN connectors found in homes and businesses. They can be used on the ends of either flat cable or CAT5. 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 that may cause signal problems. In addition, apply a generous amount of CaiLube

™

contact cleaner to remove any foreign matter

™

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

6. Quick Connect Jack:

The display uses quick connect jacks for the connection of such things as the temperature sensor, a client radio, and connection of the primary to the secondary or mirror display. The quick conne ct jacks are located on the back of the display and when not used the attached dust cover should be kept closed.

To attach the cable to a jack, make sure to line up the

plug to match the jack, push the plug in then turn the outer collar to lock in place. Figure 14 illustrates the 6pin quick connect jack.

3.2 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 from the j-box at the base of the sign structure to the display. This cable has a maximum length of 25 feet (7.6 meters).

3-2

Electrical Installation

RS422

This cable is a 4-conductor shielded cable used to transmit an RS422 signal (Daktronics part number W-1234). This shielded cable consists of paired 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 interference

signals

With interference 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).

Modem

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

Ask the telephone company which colors are used for the tip wire and which for the ring wire for signal connections. Note: The telephone line to the display must be a dedicated line and not run through a switch board/communications 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 it 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 through a J-box, requires an 18-gauge six-conductor cable (Daktronics part number W-1370). Four-conductors will be used for the signal and two for power. This cable from the J-box to the Server radio, needs to be in conduit when exposed to outdoor conditions. The maximum distance from the J-box to the Server radio is 1000 feet (305.8 meters).

The Client radio at the display comes with cable that is rated for outdoor use and does not need to be in conduit. The cable should be secured to the structure so it cannot pulled loose from the display by weather or vandalism.

3.3 RJ Connector Cables

The conductor connector used in the network is an industry standard, 6-pin RJ11or 8-pin RJ45. This connector can be found on many telephones and LANs.

The cable used in the network is a standard flat six-conductor telephone cable (standard flipped cable). Refer to

Figure 15 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 16 for a standard flipped cable.

Electrical Installation

Figure 15: 6-Conductor RJ11 Connector and Cable

3-3

Notice below in

Figure 16 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 simp le 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.

Figure 16: Flipped Cable with RJ Connectors

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

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 a pliers to crimp the connector onto the wire. This completes the installation of an RJ connector onto the wire.

3.4 Conduit

Reference Drawings:

Shop Drawing; AF-3150-**x**-20mm-R or A............... Drawing B-183660

Daktronics does not include the conduit. Refer to Drawing B-183660 for your display size and approximate locations for power and signal conduit. Separate conduit must be used to route:

• Power

• Signal IN wires

• Signal OUT wires (if signal is required for another display)

Knockout holes for ½" conduit are located at the bottom right (rear view) of th e back of the display (refer to Drawing B-183660).

For displays with more than one face, signal and temperature sensor wiring between displays is normally done using the quick co nnect i nt erconnect cable, which does not need to be in conduit. When not using the quick connect cable, the cables for signal and temperature can be routed through the same conduit.

3.5 Preparing for Power/Signal Connection

Reference Drawings:

Component Layout Drawings................................... Refer to Appendix A

1. Remove the two bottom left modules (AX01 and AX02) to expose the

power enclosure and controller. Use a access fasteners one-quarter turn. Turn the top latch clockwise and the bottom latch counterclockwise. Lift each module away from the display; reach behind it, and disconnect all power and signal connections.

2. Locate the controller and

power termination box for these displays in the

Component Layout Diagram located within Appendix A.

3. Punch or use 7/8" (0.875)

holes for the desired ½" conduits. Be careful that

none of the internal components are damaged.

Attach the conduit.

4. The controller receives the incoming signal and relays it to the individual

modules.

5. Rou te power to the display through a fused disconnect switch capable of

opening all ungrounded power con d uct or s. Inst all thi s di sconnect within the line-of-sight of any personnel performing maintenance on the display. If the disconnect is located out of sight of the display, it must be capable of being locked in the open position.

6. Power conductors from the disconnect to the display should be routed

through conduit in agreement with local code.

7. You may route the signal cable from the control computer to the display at

this time also. Unless you are using fiber, be sure to run the power and signal cables in a separate conduit.

Electrical Installation

3-5

Proper power installation is imperative for proper display operation. The following sub-sections give details of display power installation.

Grounding

This display is intended to be installed in accordance with the requirements of Article 600 of the National Electrical Code and/or other applicable local codes. This includes proper grounding and bonding of the display.

Displays must be grounded according to the provisions outl i ned in Article 250 of the National Electrical Code less.

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

. Daktronics requires a resistance to ground of 10 ohm s or

3-6

Figure 19: Display Grounding

The material of an earth-ground electrode differs from region to region, and from conditions present at the site. Consult the National Electrical Code and any local electrical codes that may apply. 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.

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 requires that the resistance to ground be 10 ohms or less. If the resistance to ground in 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.

Electrical 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:

rInstallation with Ground and Neutral Conducto s Provided

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 requires the use of a lockable power disconnect within sight of or at the sign.

Figure 20 below for installation details. The National Electrical Code

Figure 20: Installation with Ground and Neutral Conductor Provided

Installation with 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 followi n g guidelines must be observed:

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

sign 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 sign panel

board.

Refer to

Figure 21 below for installation details.

Power Connection

Reference Drawings:

Power Termination Box............................................... Drawing A-129227

Schematics...............................................................Refer to Appendix A

Incoming power is connected within the power termination enclosure. Complete the following steps to terminate the hot and neutral wires at the termination block within the enclosure. Refer to Drawing A-129227 and the Schematic listed within

Appendix A for your display size.

1. Access the enclosure by removing the left bottom two modules as described in Section 3.5.

2. Route the power cables through the power conduit in the rear of the sign

and to the enclosure.

3. Conn ect the white neutral wire to neutral bus.

4. If one power line is being terminated (120VAC), connect the black “hot”

wire to L1. Make sure the jumper from L1 to L2 is in place as shown on

Drawing A-129227.

5. If two power lines are being terminated (120/240VAC). Connect the second

“hot” wire to L2. Make sure to remove the jumper between L1 and L2.

6. Conn ect the green grounding wire to the grounding bus E41.

3-8

Main Disconnect

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

3.7 Signal Termination from Computer to Display

Figure 22: Signal Termination at Display (Front View)

Figure 22 gives the general location of various control components of the display.

The location of the display controller and power termination panel may vary slightly depending on the height of the display. Note: The AF-3150 is designed for quicker connection to other displays, and to addition components such as a temperature sensor or a client radio. Connection of the communication equipment to the primary display can be done using a cable with a quick connect or can be wired directly to the controller in that display. Depending on the number of displays and the communication type ordered, the following cables may be provided with the displays:

1. Interconnect cable from primary display to secondary display, length 4 feet.

2. Temperature sensor with quick connect cable, length 25 feet.

3. Client radio with qu ick connect cable, length 25 feet.
