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 need for additional features and the complexity of multiple display installatio ns has emerged. Daktronics display system s have been desi g ne d to m eet those n eeds.

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. Daktronics designs products with great care that satisfy a wide variety of installations. Some of the design goals of these systems include the following:

• 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 Optic,

Radio. Up to 240 displays can exist on one network.

and

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. All computers have an RS232 communications port. Refer to Section 3 for additional information.

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 1.2km (approximately 4,000 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. Refer to Section 3 for more 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 uses to communicate between controller and display. Each modem network needs to have a dedicated phone line assigned to it. 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 signal to fiber optic signal; a minimum of two fibers is required. Refer to Section 3 for additional information.

Introduction

1-3

Page 10

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 distance of 450 meters (approximately 1,500 feet) outdoor and 150 meters (approximately 500) indoor. 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 the Venus 1500 Radio manual, E D-13932, for additional information.

1.6 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.

A module is the building block of the

Galaxy

display. Each module measures 8 pixels high by 16 pixels wide. By placing modules side-by-side and on top of one another, a display of any size can be designed and built. Individual modules can be easily removed from the display if required. Daktronics numbers modules on a Galaxy display.

Figure 5 above illustrates how

Figure 6 on the right demonstrates

Figure 6: Module Numbering

the module numbering method.

In addition, the following labeling formats might be found on various Daktronics drawings:

• “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_ _” identifies a power or signal plug for the opposite jack.

Finally, Daktronics part numbers are commonly found on drawings. Those part numbers can be used when requesting replacement parts from Daktronics Customer Service. Take note of the following part number formats:

• “0P-_ _ _ _-_ _ _ _” shows an individual circuit

board, such as the internal fiberboard.

• “0A-_ _ _ _-_ _ _ _” indicates an assembly,

such as a circuit board and the plate or bracket to which it is mounted. A collection of circuit boards working as a single unit may also carry

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.

Only a qualified individual should terminate power within this Daktronics display or signal to the signal enclosure.

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. 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 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

Figure 10 on

the right.

3. Phoenix

™

-Style Connectors:

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

Figure 11 on the right. Strip one-quarter inch

of insulation from the wire prior to termination. To remove a wire, turn the above screw counterclockwise 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:

Figure 11: Phoenix Connector

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. RJ11/RS45 Connectors:

RJ connectors, as seen in

Figure 13 on the lower right, 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. RJ11 connectors use six-conductor cable and RJ45 connectors use eight-conductor cable.

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 to the plug before inserting it into the

™

Figure 12: Maten-Lok Connector

jack. This paste will protect both the plug and the jack from corrosion.

6. Six-Pin Insulation Displacement Connector:

The six-pin connectors found in the display are keyed connectors, meaning that they will only go together one way and should not be forced. To remove the connector, squeeze the plastic tab and gently pull the plug from the jack.

3.2 Control Cable Requirements

RS232

A quick connect cable for an RS232 display will connect from the communication enclosure to the display. The quick connect cable is provided by Daktronics.

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 d

• In

With interference signals, such as power c foot separation is required. The maximum length of an RS422 signal cable is 4,000 feet (1.22km) from the signal converter to the enclosure at the display.

Modem

The modem option will use a 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 the RING wire for signal connections to the modem enclosure at the display.

Note: T board/communications system.

edicated, metallic conduit

side buildings – if cable is not in conduit, keep away from interference

signals.

onductors, intercom, etc., typically a two-

he telephone lines must be dedicated lines, and not run through a switch

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 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) from the signal converter to the fiber enclosure at the display.

Radio

The Server radio connected to the computer requires an 18-gauge six-conductor cable (Daktronics part number W-1370). Four-conductors will be used for the signal and two for the power. These wires need to be in conduit when exposed to outdoor conditions to the Server radio. The maximum distance from the J-box by the computer and the Server radio is 1,000 feet (305.8 meters).

The Client radio at the display comes with cable that is rated for outdoor use and

s not need to be in conduit. The cable should be secured to the structure to

doe prevent it from being pulled loose from the display.

Display Enclosures

In each communication method, the final termination will be from a provided weather resistant enclosure to the display.

Note the following information when mounting the enclosure:

1. Be sure to mount the enclosure with the cable exiting from the bottom, to prevent water from entering into the enclosure.

2. Mount the enclosure securely and if possible at a height inaccessible to vandalism.

3. A quick connect cable will be connected to the enclosure and will terminate to the back of the Primary display. The length of the cable is either 25 or 30 feet depending on the communication method used.

4. The quick connect cable can be run from the enclosure though conduit or through the display pole to the sign, but is not required. The cable is weather and sunlight resistant.

5. Daktronics strongly recommends that the cable be secured to the display to prevent it from being pulled loose by weather or vandalism.

6. Ground those enclosures that use wire signal cable, which includes the RS422 and modem. The resistance to ground should be 10 ohms or less. A wire is attached to the enclosure to make the necessary ground connection.

3.3 RJ Connector Cables

The conductor connectors used in the network are an industry standard 6-pin RJ11or 8-pin RJ45. These connectors can be found on many networks and LANs.

The cables used in a network are a standard eightconductor Cat-5 cable. Refer to

Figure 14 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 cable.

Figure 15 below for a standard flipped

Figure 14: Eight-Conductor Cable

Notice below in

Figure 15 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.

Daktronics does not provide the conduit. Refer to Drawing A-193720 or A-201993 for your display size for 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 A-193720 or A-201993).

For displays with more than one face, signal and temperature sensor wiring between displays is done using a quick connect interconnect cable.

4. An enclosure receives the signal from the

control computer and transfers it to the display controller. The controller receives the incoming signal and relays it to the individual modules.

5. Route power to the display through a fused

disconnect switch capable of opening all ungrounded power conductors. Install this disconnect 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 also route the signal cable from the display enclosure to the display at this time.

8. Note: Always use water resistant boxes for signal/power termination enclosures to prevent corrosion or other physical damage to interior parts.

Power Requirements

Refer to Drawing A-200044 or A-200045 for voltage and current requirements for your display size. Each uses a 120VAC single-phase power source. Depending on the module color and display size the power supply may vary.

Do not connect the displays 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.

Grounding

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

The display system must be connected to earth-ground. Proper grounding is necessary for reliable equipment operation. It also protects the equipment from damaging electrical disturbances and lightning. It is recommended that an eight gauge copper wire be connected to the ground rod. The display must be properly grounded or the warranty will be void.

. Daktronics recommends a resistance to ground of 10

3-6

Electrical Installation

Page 27

Figure 19: Ground Conductor

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 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.

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

Power Installation

There are two considerations for power installation: installation with ground and neutral conductors provided, and installation with only a neutral conductor provided. For these displays, installation with ground and neutral conductors provided is used.

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 20 for installation details. The National Electrical Code requires the

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

Incoming power is connected to the power termination panel. Complete the following steps to terminate the hot and neutral wires at the termination block within the display. Refer to Drawing C-200002 for your display.

1. Access the panel by opening the display as described in Section 3.5.

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

and to the power term panel.

3. Connect the white neutral wire to termination block, TB41–2.

4. Connect the hot wire to termination block at TB41-1.

5. Connect the green grounding wire to the grounding bus, E41 . Refer to

Figure 20 on the previous page.

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 that all power lines can be completely disconnected. Use a 3-conductor disconnect so that 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.
