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 4.13 provides the names and numbers of components that may need
to be replaced 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-_ _ _ _-_ _ _ _ (circuit board) or 0A-_ _ _ _-_ _ _ _ (multi-component assembly).

Following the Replacement Parts List is the Exchange and Repair and Return
Programs in Section 4.14. Refer to these instructions if any sign component needs
replacement or repair.

1.2 Network Concepts

The concept of using LED displays as 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 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
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 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

Introduction

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

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

o. One network system can operate up to 240 display s .

radi

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
distance 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 ED13932 for the additional information.

Figure 4: Signal Converter

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.

Figure 5: Module Numbering Example – 24x64 Front

A module is the building block of the sign.
Each module measures 8 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 from the
sign if required. Figure 4 above illustrates how
Daktronics numbers modules on a Galaxy

®

sign. Figure 5 on the right breaks down the
module numbering method.

Figure 6: Module Numbering

Introduction

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

• “TB_ _” shows a termination bloc k f or pow er or si g nal cable.

• “F_ _” denotes a fuse.

• “E_ _” signifies a grounding point.

• “J_ _” stands for a power or signal jack.

• “P_ _” represents a power or signal pl u g fo r t he op po si t e ja ck.

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-_ _ _ _-_ _ _ _” gives the form of an individual circuit board, such as a

line receiver.

• “0A-_ _ _ _-_ _ _ _” represents 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-_ _ _ _” indicates a wire or cable. Cables may also carry the assembly

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

• “F-_ _ _ _” signifies 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 4.13 does not list a circuit
board or assembly, use the label to order a
replacement. Figure 6 on the right illustrates
a typical label. The part number is in bold.

Section 2: Mechanical Installation

Daktronics engineering staff must approve any changes that may affect the weather-tightness
of the display. 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.

Daktronics is not responsible for installations or the structural integrity of support

tures done by others. The customer is responsible to ensure a qualified structural

struc

engineer approves the structure and any additional hardware.

Because every installation site is unique, Daktronics has no single procedure for
mounting Galaxy
or may not be appropriate for your particular installation.

®

displays. This section contains general information only and may

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

Read both the mechanical and electrical installati
before beginning any installation procedure.

2.2 Support Structure Design

Support structure design depends on the mounting methods, sign size and weight.
Since the structure design is critical, only a qualified individual should mount the
display. Display 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 instal
support structures done by others.

The installer is responsible to ensure the mounting structure and hardware is
capable of supporting the display and agrees with local codes.

Before beginning the installation proces s, 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 behind the sign for

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

2.3 Ventilation Requirements

Reference Drawings:

Shop Drawings....................................................................... Appendix A

Fans mounted in the backsheets toward the top of the display allow for ventilation.
Maintain a minimum distance of 3" (7.62 cm) behind and below the display 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 un obstructed opening per module to ens ure

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 (20" x 20" active area).

Failure to comply with these requirements voids the Galaxy® display warranty.

2.4 Lifting the Sign

2-2

Figure 8: Lifting the Sign (left; correct) and (right; incorrect)

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

Figure 7 above 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 display by the eyebolts.

If you remove the eyebolts, adequately seal the holes using 13 bolts and sealing
washers, ½ inch in size. Silicone along the threads to ensure water does not enter the
display.

2.5 Sign Mounting

Reference Drawings:

Shop Drawings

The method used to mount displays varies greatly from location to location. For this
reason the manual covers only general mounting topics.

The installer is responsible to
codes and standards. The installer is also responsible for the mounting method
and hardware.

Before beginning the installation proces s, verify the following items:

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

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

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

the display is mounted.

The back of the display uses 3x2x3/8" steel clip angles at the locations shown in the
Shop Drawings. These angles assist in mounting the sign. Remember to have all
mounted signs inspected by a qualified structural engineer.

The customer must ha

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.

The ideal sensor location is a north eave
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 8 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 light­colored 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 below the
display, a minimum of 8 feet
above ground is required

Do not mount the sensor between the displays.

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

1. The temperature sensor will be connected to the display through a Quick

Connect input plug on the back of the first face. The sensor connects to the
display at J31. Remember to secure any excess cable to prevent vandalism.

2. The quick connect signal cable between displays connects both

communication and temperature signal, thus no additional wiring is
required from display to display for the temperature sensor.

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.

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 display. Before
altering the display, 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.

3.1 Common Connectors in the Sign

The power and signal connections in the signs use many different
types of connectors. Tak e special care when disengag ing 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 10 on the right illustrates a typical ribbon

connector. To disconnect the ribbon cable, push the plastic
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 CaiLub
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
Figure 11 on the right.

3. Phoenix™-Style Connectors:

Phoenix-style connectors, usually green, allow for signal
termination on circuit boards. Refer to Figure 12 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 13 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 bo ard
and twist it counter-clockwise until you can pull
the plug from the jack. Figure 14 on the right
shows this connector.

6. Phone Jacks (RJ1 1 Co nnect ors) :

RJ connectors, as seen in Figure 15, 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
that may cause signal problems. In addition, apply a
generous amount of CaiLube
plug before inserting it into the jack. This paste will
protect both the plug and the jack from corrosion.

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 at the base of the display structure.
This cable has a maximum length of 25 feet (8 meters).

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 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

3-2

Electrical Installation

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).

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 by the TIP and the RING for
signal hook-up.

Note: The telephone line must be a dedicated line 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 one six-conductor 18 AWG
cable (W-1370) for the signal and the power. This cable needs to be in conduit when
exposed to outdoor conditions. The maximum distance from the J-box to the Server
radio is 1000 feet (304.6 meters).

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

3.3 RJ Connector Cables

The connector used for RS/232 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 six-conductor
telephone cable (standard flipped
cable). Refer to Figure 16 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 17 below for a standard flipped cable.

Notice in Figure 18 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 display 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.

Electrical Installation

Figure 17: 6-Conductor RJ11 Connector and Cable

3-3

Figure 18: 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 Figure 19 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.

3.4 Conduit

Reference Drawings:

Shop Drawings....................................................................... Appendix A

Daktronics does not include the conduit. Refer to the Shop Draw i ng for approximate
locations of power and signal conduit. You must use separate conduit to route:

• Power

• Signal IN wires

• Signal OUT wires (if anot her si gn requires signal)

Locate the conduit holes at the bottom right (rear view) of the back of the sign.
Refer to Shop Drawings for appropriate locations.

Punch or drill out the desired conduit openings. Be careful not to damage any
internal components. Attach the conduit, and then route the power and signal cables.

For displays with more than one face, a quick connect cable is provided to connect
the output on the first display to the input on the second.

If the displays are not back-to-back or are too far apart for the quick connect cable,
other cables for signal and the temperature sensor wiring can be used. In that case,
the same conduit can be used between displays to route the signal cables.

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.

Electrical Installation

3-5

Figure 20: Display 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 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 power term panel.

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 because of 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:

3-6

Installation with Ground and Neutral Conductors 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 Figure 20 below for installation details. The National Electrical Code
requires the use of a lockable power disconnect within sight of or at the display.

Electrical Installation

Figure 21: 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
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 21 below for installation details.

Figure 22: Installation with only Neutral Conductor Provided

Electrical Installation

3-7

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.

3.8 Signal Termination from Computer to Sign

Figure 23: Signal Termination

Note: The AF-3180 is designed for quicker con necti o n t o ot her displays and other
additional equipment. Connection of the control computer to the first d isplay needs
to be wired to the surge suppressor, modem, or fiberboard in that display. The
following cables are provided with the displays:

1. Interconnect cable from Display 1 to Display 2, length 10 feet.

2. Temperature sens or wi t h Qui ck C onnect cable, length 10 feet.

3. Client radio with Quick Connect cable, length 25 feet.

A display that is controlled using RS232 requires the use of a J-box within 25 feet of
the display. From the J-box to the display, the signal may be connected using a quick
connect cable or directly wired to the controller inside the display. The cable from
the J-box to the display must be routed though conduit. Do not run signal and display
power through the same conduit.

Electrical Installation

1. If using a quick connect cable, connect from the J-box to J33 on the back of

the display.

2. When connecting directly to the display, terminate one end at the J-box and
the other end of the wire to the 6-position terminal block on the controller
labeled “RS232 IN” (A31-TB1). Drawing B-177662 shows the terminal
block wiring. Drawing B-177838 shows the controller.

A display that is controlled using a modem requires the use of an internal or external
modem at the computer. The local phone company must provide a dedicated phone
line to the display and identify the colors used for “Tip” and “Ring”. The telephone
cable is terminated to TB2 on the modem in the display or to a plug that is connected
to the Quick Connect at the display. The phone cable must be routed though conduit.

Do not run signal and display power through the same conduit. Refer to
Drawing A-174342 for system layout.

1. If using a quick connect cable, connect the phone line to J32 on the back of

the display. A 6-conductor phone cord wit h R J11 con nect o rs (Da kt r oni cs
part number 0A-1137-0160) relays the signal to the modem.

2. When connecting directly to the display, terminate the phone line to TB2 on

the display modem. If the phone company provided a phone termination
box in the display a straight phone cable can be connected from the box to
the J5 Phone IN on the modem board in the display. Drawing B-177662
shows the terminal block wiring.

3. A second phone cord (Daktronics part number 0A-1137-0160) transfers

data from J6 on the modem to J3 (RS232 IN) on the controller.

A display that is controlled using a radio requires a Server radio connected to the
control computer, and a Client radio at the display. The radios must be within line­of-sight of each other. The diagram below shows the connections through a signal
converter. The Client radio must be located within 25 feet of the display, therefore
25 feet of cable is supplied with the Client radio. One end of the cable is pre­terminated to TB1 inside the radio enclosure, and a quick connect plug is terminated
at the other end of the cable. If necessary the cable can be cut and terminated directly
to the controller board in the display. Refer to Drawing B-177662 for the correct

The Quick Connect cable is the most common method of terminating signal between
two displays. The ten-foot cable goes from the RS422 OUT on the first display to the
RS422 IN on the second display.

If the displays are not back-to-back, or
are too far apart for the quick connect
interconnect cable to reach, a 4­conductor shielded cable of the correct
length is used. One end will connect at
the “RS422 OUT” 6-position controller

4.3 Signal Summary

The signal routing for the display can be summarized as follows:

1. Data from the controller computer, which runs Venus

travels via RS232, RS422, modem, fiber optic cable, or Client radio into the
display.

2. For multiple face display or a display network, an RS422 Quick connect,

interconnect cable (most typical) or fiber cable relays signal between the
controller of the first display and the controller in the second display.

3. From the controller, the signal then travels over 20-conductor ribbon cables

from the controller (J11 through J16 provides signal out) to J2 on the driver
of the first row of modules in the display.

4. Data exists at J1 and is relayed to J2 of the next driver board and so on,

traveling down the entire row of modules. The drivers use this display data
to control the LEDs.

4.4 Power Summary

The following describes the internal display power routing for the display:

1. Incoming power terminates at the panel board.

2. +12.5VDC power supplies power the modules in a both the monochrome

red and amber displays.

Reference Drawings:

Controller, Galaxy, 8 conn., J1087...............................Drawing B-177838

The controller sends data to the modules. Refer to the signal summary in Section 4.3
for more information and to the component location drawings for the position of the
controller board. Figure 36 below illustrates a typical controller.

Figure 39:Controller

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 the 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. The display's
power must be turned off and then turned back on to run the test mode.

Maintenance and Troubleshooting

Fiber Board

The fiber module has three LEDs.
The power LED (DS1) should
remain lit while power is applied to
the module. The receive LED (DS2)
will light when the display fiber
board is accepting signal from the
computer fiber board. The transmit
LED (DS3) will light when the
display fiber board is sending to the
computer fiber board. In addition,
the fiber module has two input fiber
connectors, which the computer or
the previous display connects to,
and two output fiber connectors that
connect to the next display. The
fiber board connects to the
controller board with a straight
through RJ11 cable.

To replace a fiber optic board:

1. Disconnect the power and

signal connections (refer to
Figure 39 above for
disconnection of power).

2. The fiber optic board is held in place with four screws. Carefully remove

them.

3. Install the new fiber optic board, replace the screws and reconnect power

and signal cables.

RS422 Surge Suppressor

The surge suppressor is an inline device that is used to filter the RS422 data line. It

suppresses surges down to a low voltage in order to protect the display controller's
RS422 input. The surge suppressor must be firmly connected to the displays chassis
in order to be effective. The mounting hardware used to secure the surge suppressor
is sufficient if it is fastened properly.

1. Open the display as

described in Section 4.5.

2. Disconnect the signal

connections (refer to
Figure 40 on the right).

3. The surge suppressor is

held in place with four

Location of CAN termination jumper

Temperature and light sensors are controlled as part of a CAN network. For the CAN
network to work correctly, the network must be terminated at both ends of the
network. This is true for a single display, or multiple displays. The correct
terminations are completed during the building process. However, if the order or
number of displays is changed on-site, the terminating jumper may need to be
relocated.

Figure 44: Displays with No External Temperature Sensor

In the case of those displays that utilize a temperature sensor, the sensor is internally
terminated. Therefore, only one other termination needs to be made at the output of
the last sign in the network. The most common input location for the temperature
sensor is to the first display in the network.

Figure 45: Displays with External Temperature Sensor

The terminating jumper is located on the quick connect board on the inside of the
display. Most displays have both an input and an output quick connect board. When
no output board is available, the terminating jumper will be placed on the input board
of the last display. Therefore, both boards are shown on the previous page in Figure
41 and Figure 42.
