Daktronics displays are built for long life and require little maintenance. However, from time
to time, certain display components may need replacing. The Replacement Parts List in
Section 4 provides the names and numbers of components that may need to be ordered during
the life of the display. Most display components have a white label that lists the part number.
The component part number is in the following format: 0P-____-____ (component) or 0A­____-____ (multi-component assembly).

Following the Replacement Parts List is an explanation of Daktronics Exchange and
Repair and Return Programs in Section 4.7. Refer to these instructions if any display
component needs replacement of repair.

1-2 Introduction

1.1 Safety Precautions

Important Safeguards:

1. Read an d understand these instructions before installing your
display.

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

3. Prop erly 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.

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

Current Loop

The DataMaster controller connects to the Rate 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. Current-loop 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 d isplay. Refer to
Section 3 (Electrical Installation) and the Section 5 (Rate Display Operation) for
additional information.

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 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 (Rate Display Operation) for additional
information.

1.4 Component Identification

The following terms include 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 Secti

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.

In addition, 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 drive r
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.

2.3 Lifting the Display

Model DF-1030/DF-1040 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 in which an ad panel 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. If removing the
eyebolts, adequately seal the holes using bolts and sealing washers. 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 openings with silicone.

Daktronics requires a resistance-to-ground of 10 ohms or less.

The contractor performing the electrical installation can verify ground resistance.
Tech

cians from Daktronics Sales and Service offices can also provide this service.

ni

The display system must be

c

onnected 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 earth-ground electrode. Connection at the driver
enclosure terminal block is illustrated at the bottom of the drawing.

The material for an earth-ground electrode diffe

from region to region and may

rs
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 installatio

n

: 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
in

stallatio

n, 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 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. Installatio

s where no

n
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 enclosur e.

• 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.

Host/Client Definitions................................................. Drawing A-185236

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 photo/light sensor. The “Signal OUT”
terminals are used to connect to “client drivers.” Refer to Drawing A-185236 for an
illustration of the client/host driver display setups.

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 for 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/slave displays.” The term s “m aster/slave”
or “primary/mirror” should not be confused with “host/client. ” Mirror/slave displays
do not contain a driver and may use either the client or host digit outputs.

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.” This 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 in

Figure 13 for setting the

address.
