(multi-component assembly).

Following the Replacement Parts List is an explanation of Daktronics Exchange
and Repair and Return Programs. Refer to these instructions if any display
component needs replacement or repair.

1-2 Introduction

1.1 Safety Precautions

Important Safeguards:

1. Read and understand these instructions before installing your
display.

2. Do not drop the controller or allow it to get wet.

3. Properly ground the display with a ground rod at the sign
location.

4. Disconnect power when the display is not in use.

5. Disconnect power when servicing the display.

6. Do not modify the display structure or attach any panels or

coverings without the express written consent of Daktronics,
Inc.

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
common thread of most requests is a means of programming and controlling the
displays in a variety of ways.

There are three communication methods available: Current Loop, Radio, and
Modem.

Current Loop

The DataMaster controller connects to the Gas Price Display either from a j-box
located outside near the display or from an indoor location. The communication
method is current-loop to the host display, and from the host to the client. Current­loop is a standard communication method that uses a maximum cable length of 600
meters (approximately 2000 feet). Refer to Section 3 for additional information and
connections.

Radio

The radio network is a standard communication method that uses radio waves at
high frequencies to transmit signal. The radio network has a maximum distance of
450 meters (approximately 1,500 feet). A nearly straight line-of-sight path must be
maintained between the Server Radio connected to the DataMaster controller,
through a signal converter, and the Client Radio connected to the display. Refer to
Section 3 (Electrical Installation) and the Section 5 (Gas Price Display Operation)
for additional information.

Introduction 1-3

Modem

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 the DataMaster and display. Each modem
network needs to have a dedicated phone line assigned to it. Refer to Section 3
(Electrical Installation) and the Section 5 (Gas Price Display Operation) for
additional information.

1.3 Product Overview

1.4 Component Identification

The following list includes some of the more commonly used terms when
referring to these displays. Because Daktronics occasionally alters standard design
to meet customer needs, the actual display design may vary slightly from the
illustrations below.

This is only a brief overview. Refer to Section 4 for additional information on
maintaining the various display components.

Client: The client display contains a client driver that receives signal from the
“host” driver on the Signal IN terminals. These drivers can re-drive signal to other
client drivers.

DataMaster Controller (DM100): The handheld keyboard-like device used to set
the time, date, hold times, dimming etc. on the Gas Price display. See Section 5 for
more information on the DataMaster controller.

Display Address: The display address is an identification number assigned to each
driver in a network. The address is set using an 8-position binary switch on the
driver board. For single-line signs such as a Time & Temp display, the address will
typically be “1”. For Gas Price displays, the top display is often set to address “1 ”
and the others are set to “2”, “3” etc. The address will be displayed each time the
display powers up.

Digit Circuit Board: The LEDs are mounted to a circuit board, which mounts to the
back of a digit panel. Problems with individual digits, segments or LEDs may
require accessing or replacing this board.

Host/Primary: The host display contains the host driver which relays signal directly
from the DataMaster controller on its Signal IN terminals. It is the only driver
connected to the temperature/light sensor. The Signal OUT terminals are used to
connect to the client driver. The host driver is selected by inserting the protocol 4­plug into the protocol jack.

LED (light emitting diode): LEDs are high-intensity, low-energy lighting units.

Introduction 1-5

Mirror/slave: receives power and a digit harness from the master but does not have
a driver.

Power Supply: Converts AC line voltage from the load center to low DC voltage
for one or more digit circuit boards.

Protocol plug: The protocol 4-plug is inserted in the 5-pin protocol jack to select the
host driver for a set of host-client displays.

1.5 Daktronics Nomenclature

To fully understand some Daktronics drawings, such as schematics, it is necessary to
know how various components are labeled in those drawings. You will find this
information useful when trying to communicate maintenance or troubleshooting
efforts.

The following labeling formats might be found on various Daktronics drawings:

• “TB _ _” denotes a termination block for power or signal cable.

• “E _ _” denotes a grounding point.

• “J _ _” denotes a power or signal jack.

• “P _ _” denotes 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. (Not all possible formats
are listed here.)

• “0P- _ _ _ _- _ _ _ _” denotes an individual circuit board, such as a driver
board.

• “0A-_ _ _ _ - _ _ _ _” denotes 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 an assembly label.

• “W- _ _ _ _ ” denotes a wire or cable. Cables may also carry the assembly
numbering format in certain circumstances. This is especially true for
ribbon cables.

Most circuit boards and components within this display carry a label that lists the
part number of the unit. If a circuit board or assembly is not listed in the
Replacement Parts List in Section 4.6, use the label to order a replacement. A
typical label is shown in

Figure 3. The part number is in bold.

2.2 Lifting the Display

Model DF- displays are shipped equipped with 3/8" eyebolts that are used for
lifting and positioning the modules. Eyebolts are located along the top outer
edges of the cabinet.

Daktronics strongly recommends using a spreader bar, or lifting bar, to lift the
display. Using a spreader bar ensures that the force on the eyebolts is straight up,
minimizing lifting stress.
incorrect (right example) method for lifting a display. Lift the display as shown on
the left, with a lifting bar. Be sure to use every lifting point provided.

Figure 4 illustrates both the correct (left example) and the

Figure 4: Lifting the Display

Note: Daktronics assumes no liability for display damage or injury resulting
from incorrect setup or incorrect lifting methods.

Eyebolts are intended for lifting during installation only. Do not attempt to
permanently support the display by the eyebolts.

In installations where an ad panels or some other display section may be added to the
base display, the lower section is installed first and secured to the support beams,
and then the upper section is placed atop or above the lower sign section and
attached to the beams. There may be cables extending from the top of the lower
section. Guide these cables into the hole in the bottom of the upper section for later
connection.

Installers may remove the lift eyebolts once the display is in place. When removing
the eyebolts, adequately seal the holes using bolts and sealing washers. Smaller
displays use

3

/8"-16 bolts, larger displays use 1/2"-13 bolts into the holes. In addition,
inspect the top and sides of the display for any holes or openings that may allow
moisture to enter the display, and plug and seal those opening s with silicone.

Electrical Installation 2-3

Section 3: Electrical Installation

Daktronics outdoor displays are UL listed and tested to CSA standards for outdoor use.

Grounding

Reference Drawings:

Enclosed Driver, 4 Column Reference ........................Drawing A-184918

Displays MUST be grounded according to the provisions outlined in Article 250 of
the National Electrical Code and according to the specifications in this manual.
Daktronics requires a resistance-to-ground of 10 ohms or less.

The contractor performing the electrical installation can verify ground resistance.
Technicians from Daktronics Sales and Service offices can also provide this service.

The display system must be connected to an earth electrode installed at the display.
Proper grounding is necessary for reliable equipment operation. It also protects the
equipment from damaging electrical disturbances and lightning. The display must
be properly grounded, or the warranty will be void. Refer to Drawing A-184918, for
information on where to connect the grounding wire. Connection at the driver
enclosure terminal block is illustrated at the bottom of the drawing.

The material for an earth-ground electrode differs from region to region and may
vary according to 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 it is in earth, the steel is usually primed or it corrodes, making it a
poor ground in either case.

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:

Installation with Ground and Neutral Conductors Provided
For this type of installation, the power circuit 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 lines can be disconnected.
The National Electrical Code requires the use of a lockable power disconnect within
sight of or at the display.

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 following guidelines must be observed:

• Connect the grounding electrode cable at the local disconnect, never at the
display driver/power enclosure.

• Use a disconnect that opens all of the ungrounded phase conductors.

Electrical Installation 3-3

3.3 Lightning Protection

The use of a disconnect near the display to completely cut all current-carrying lines
significantly protects the circuits against lightning damage. The National Electrical
Code also requires it. In order for this device to provide protection, the power must
be disconnected when the display is not in use. The control console should also be
disconnected from power and from the signal j-box when the system is not being
used. The same surges that may damage the display's driver can also damage the
driver console's circuit.

3-10 Electrical Installation

Host/Client Definitions

One driver at each sign installation is designated as the “host driver.” This driver

receives its signal directly from the controller on the “Signal IN” terminals, and it is

the only driver that is connected to the light sensor. The “Signal OUT” terminals are

used to connect to “client drivers.” Refer to Drawing A-168376 and

Figure 13 for an

illustration of the host/client display connection.

Figure 13: Host, Signal Out to Client, Signal In

Select the host driver by inserting the Protocol 4 plug into the 5-pin protocol jack

(J20.) For protocol jack location, refer to Drawings A-166216, A-167237 or A-

184475 on your specific display driver.

The 12 V DC terminals connected to the host driver (see “Signal Connections” in

Figure 5) run to the controller junction box. This output is used to power the

DataMaster 100 controller.

All other drivers in the display system are client drivers. These drivers receive signal

from the host driver on the Signal IN terminals and can re-drive this signal to other

“client drivers” on the Signal OUT terminals.

Some multiple-module signs use “mirror displays.” These displays do not contain a

driver and may use either the client or host digit outputs. Refer to Drawing A-

168376 for an illustration of the host/client driver and primary/mirror display setups.

Some displays only use one driver for multiple product lines in one common cabinet.

In this case, the signal to each line is already connected.

Address Settings

The address of each driver is set using an 8-position DIP-switch (S1), and the

address is based on that driver’s position in the sign or display system. If a single-

line sign is used, the address will typically be Address “01.” Th is means that switch

1 is turned “ON” and the remaining 7 switches are in the “OFF” position. This is the

default address set when each display is shipped. In multiple-product displays, the

address determines which line of information is shown on the driver’s digits. The

switch is set using a binary address. Use the table and the examples for setting the

address. Drawing A-227502 shows how to set the address on the drivers used in

DataTime and DataMaster products.

component access are detailed in each model's Mechanical Specifications Drawing.

4.2 Component Location and Access

Reference Drawings:

Electrical Specification Drawings.............................Refer to Appendix A

Mechanical Specification Drawings.........................Refer to Appendix A

Displays in the DataMaster Gas Price series are made up of two main components:
the circuit boards that make up the digits and the driver enclosure.

Display Digits:

• A single circuit board makes up the digits for the 10”, 13” and 18” digits

• The digits for 24”, 36”, 48” and 60” are made up of LED segments

Each host or primary display (the mirror does not contain a driver enclosure)
contains an enclosure that includes the following devices:

• Display Driver

• 24V DC power supply

• 10V AC transformer

• Signal/Power Input Terminal Jack

• Signal Board (Surge board on direct displays or a modem)

• Light (photo) sensor

Maintenance and 4-1
Troubleshooting

For the front-access modules in this series, all internal electronic components and
digits can be reached by opening either the left hinged access door on the front of the
display or removing digits.

For the 10”, 13”, 18”, and 24” displays the hinged door swings outward when the two
screws on the display face panel are removed, as shown in
displays, the enclosure is reached by removing one of the digits from the face of the
display. Since component placement varies slightly with each DataMaster model
consult your model's Electrical and Mechanical Specifications Drawings.

Note: Disconnect power before servicing the display! Disconnect power, too,
when the display is not in use. Prolonged power-on may shorten the life of some
electronic components.

4.3 Service and Diagnostics

Replacing a Digit

The digit circuit board, the platform for the LEDs, is mounted to the back of the digit
panel. Do not attempt to remove individual LEDs. In the case of a malfunctioning
board, replace the entire digit panel (10”, 13” and 18” displays). Refer to Figure 16
for the digit assembly.

To remove a display digit, follow these steps:

1. Open the digit panel as described in the preceding section.

2. Disconnect the power/signal connector from the back of the digit. Release

the connector by squeezing together the locking tabs as you pull the
connector free.

When a digit segment malfunctions, in most cases it is necessary to replace just that
segment board. The larger digits, 24", 36", 48" and 60” as shown in Figure 17
made up of LED segments. As with smaller digits, the digit segment circuit boards
are mounted to the back of the digit panel. Do not attempt to remove individual
LEDs.

To remove a digit segment, follow these steps:

1. Open the digit panel as described
above.

2. Disconnect the 2-pin
power/signal connector from the
back of the individual segment.
Release the connector by
squeezing together the locking

Segmentation and Digit Designation

Reference Drawing:

Segmentation, 7 Segment Bar Digit.............................. Drawing A-38532

Electrical Specification Drawings .............................Refer to Appendix A

In each digit, certain LEDs always
go on and off together. No matter if
they are made up of one circuit
board, or separate boards, these
groupings of LEDs are referred to
as “segments”. Drawing A-38532
illustrates digit segmentation. It
also details which connector pin is
wired to each digit segment and the
wiring color code used throughout
the display.

The Electrical Specification
Drawings specify the driver
connectors controlling the digits.

Figure 18: Digit Designation

Numbers displayed in hexagons in
the upper half of each digit, as shown in Figure

18, indicate which connector or

connectors are wired to that digit. Larger digits, like the 36" digits shown in

Figure 19: 4-column Digit Driver

DataMaster Gas Price displays may use 4-, 8-, or 16-column drivers, depending on
the model and size of digits. Each 16-column driver is so named because it has 16
outputs to digits as compared to the 8- and 4-column drivers.

Figure 19 identifies the

major functions for a 4-column driver. (Major functions are the same on 8- and 16­column drivers.)

In the display, the LED drivers perform the task of switching digits on and off. Refer

Maintenance and 4-9
Troubleshooting

Some DataMaster displays have their own built-in troubleshooting mechanism.
Failures that may occur in the display driver are described using codes. In the event
a sign malfunctions, a failure code registers by displaying an “E(x)” value on the
first two digits of the display. “E” simply indicates an error, and the letter “x”
represents the actual code number. Refer to the following table for a description of
each failure code and for possible solutions.

Note: The LCD screen on the DataMaster 100 controller will not show the failure
codes described in the table below. Failure codes will only be displayed on the
DataMaster sign.

Failure Code Description Possible Solution

E1 Protocol Setting Error: There is an

unsupported driver protocol
setting.

E2 Time Error: There is no valid time

stored in the driver; it may be a
failure of the real-time clock on
board or other timekeeping
device.

E3 Temp Error: There is no response

from the temp sensor or light
sensor, or general temp sensor
failure.

E4 No Message Error: This code is

shown when there are no
messages downloaded to the
display

E5 No Line Number Selected Error:

The driver for this line has a
Protocol 4 plug installed in J20,
but all address switches are
“OFF”. (Note: In some older
drivers this happens when no
address plug installed is in J19.)

Check the value set in the protocol
plug of the driver (J20).

Set the time in the display using the
Set Time menu option on the
DataMaster 100 controller.
(DataMaster Time & Temp displays
only)

Check the temp sensor location and
verify all connections. Refer to the
instruction sheet for the CAN
Temperature/Light Sensor
mounting, ED13364.

Note: The temp sensor takes
approximately 10 seconds to
initialize on power-up. The sign will
display this error until initialization is
complete.

Download a new message to the
display using the <DISPLAY
SEQUENCE> key on the
DataMaster 100 controller.

Set the line number by setting the
binary address on S1 (or installing
the correct plug in J19). The
Protocol 4 plug designates this
driver as the “host.” If this is not the
host, remove the Protocol 4 plug
from J20.

4-10 Maintenance and

Troubleshooting

Power On Self-Test:

A useful troubleshooting tool is the power on self-test the host driver performs every
time it powers up:

• If the signal wiring between each controller is correct, the first two digits of
each driver will display “Ad” momentarily, and the first digit will then flash
three numbers indicating the decimal address that is set with the address
plug in J19. (If a client driver displays “A <number>,” followed by “P
<number>,” it is not receiving “signal in,” and is performing its own self­test.)

• Next, the first two digits of each line will display “Lx”, where “x” is the
line number that the driver is set to control (set with address plug).

• Finally, each line will display “1234…” according to the column number of
each of its digits. Every line should show “1” on the left-most digit, and all
digits should be numbered consecutively from left to right. If this is not the
case, either the wrong address plug is installed, or the driver or digit harness
is connected incorrectly.If there is no address set (or address plug installed)
in the host driver, the host driver will display “E5,” and all client drivers
will continually cycle through the power on self-test.
