The DataMaster Lottery models detailed in this manual are part of a family of
outdoor displays designed to offer simple installation, easy readability, and
reliability. Solid-state components and microprocessor control assure consistent
operation and accuracy. The three-digit Lottery sign is illustrated in Figure 2 below.

Figure 2: DF-1060-60

Intended for use in highway and city signs and billboards, the Lottery displays
include several models: DF-1060-60, DF-106 0-48, DF-1060-36 and DF-1060-24. All
have the same layout: three LED digits separated by LED decimals. They are
distinguished from one another by their overall size and by the height of their digits.

Introduction 1-3

The displays use red or amber LEDs – light emitting diodes – to illuminate the digits.

Ds are tiny, solid-state components that use a semiconductor chip to transform

(LE
electrical current into light. They are high-intensity, low-energy lighting units.)
Because of their LED technology, the Lottery displays consume little power – barely
more than a household lamp. Maximum power usage for all three models in this
series is 300 W.

Cabinets for the displays are constructed of heavy-gauge aluminum. Cabinets are
typically black to m
Digit faceplates are black, and they are set directly into the cabinet surface.

Section 2: Mechanical and Electrical

Installation

Mechanical installation typically consists of installing concrete footings and steel beams and
mounting the display and any accompanying panels to the beams.

Electrical installation consists of the following processes:

 Providing power and ground to a disconnect near the display.
 Routing power and ground from the main disconnect to the display driver/power

enclosure.

 Connecting the display ground to a grounding electrode at the sign location.
 Routing the control signal cable from the control location to the sign location.

Lifting the Display

DataMaster Lottery displays are shipped equipped with 1/2" 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

Figure 3, below, illustrates two lifting methods. The illustration shows both the
preferred method (left example) and an alternative method (right example) for lifting
a display. Be sure to use every lifting point provided.

Figure 3: Lifting the Display

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

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

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. 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 or another waterproofing
sealant.

2.2 Electrical installation

Electrical installation consists of the following processes:

 Providing power and ground to a disconnect near the display.
 Routing power and ground from the main disconnect to the display

driver/power enclosure.

 Connecting the display ground to a grounding electrode at the sign location.
 Routing the control signal cable from the control location to the sign

location.

Note: Only qualified individuals should perform power routing and termination to

the display. It is the responsibility of the electrical contractor to ensure that all
electrical work meets or exceeds local and national codes.

Reference Drawing:

Schematic; 16 Col Multipurpose LED Drvr..................Dra

Daktronics DataMaster displays have been designed for easy access to components,
and the power and control signal hookup has been simplified. Front panels are
hinged to allow access to the digits, cabling, and other electronic components.

Correct power installation is imperative fo

r proper display operation. The
subsections that follow give details of display power installation. Only qualified
individuals should attempt to complete the electrical installation; untrained personnel
should not attempt to install these displays or any of the electrical components.
Improper installation could result in serious damage to the equipment and could be
hazardous to personnel.

DataMaster outdoor displays require a dedicated, 120 V circuit for incoming power.
Th

e display itself has no breakers or fuses.

WARNING: It is critical th

at the display circuit be fused at 15 A, and that all
conductors used must be designed to pass a 15 A current in normal operation. Failure
to meet wiring and overcurrent protection device requirements is a violation of the

Mechanical and Electrical 2-3
Specifications

The material for an earth-ground electrode diffe

rs 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 structural 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

stallation, the power circuit must contain an isolated earth-ground cond uctor. In
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

ns 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 enclosur e.

• Use a

disconnect that opens all of the ungrounded phase conductors.

Host/Client Definitions and Address Settings

Reference Drawings:

Host/Client Definitions
16 Col. MASC Driver Spec

In sign systems with multiple displays, 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/temp 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
(J2

0.) Refer to Drawing A-184475.

The 12 V DC terminals connected to the host driver (see
Figure 4) 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.
from the host driver on the Signal In terminals and can re-drive this signal to other
“client drivers” on the Signal Out terminals.

The address of each driver is set using t
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 “1.” This is the default address plug that is
shipped with each display. In a multiple-sign display, the address plug determines
which line of information is shown on the drivers' digits. The address plug for each
line is included in the address plug kit, if applicable.

Displays in the DataMaster series use a photosensor to regulate sign dimming
functions. (Dimming involves decreasing overall display intensity, both for better
display viewing and to prolong LED life. The brightness level should be highest
during the day to compete with daylight, and lower at night.)

The light sensor is typically installed at the factory. However, if field installation is
necessary, use Drawing A-183775 and the following instructions to mount the photo
sensor in your DataMaster Rate display. If the sign or sign system has more than one
display, install the light sensor in the host display only.

1. Unfasten the latch screws on

the middle digit and open the
hinged access door. The light
sensor will be mounted to the
panel between the first and
second digits. The exact
location will be shown on each
