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.

1.5 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.

Grounding
Reference Drawings:
Schematic; Multipurpose 4 Col. LED Drvr...................Draw
Schematic; 16 Col Multipurpose LED Drvr..................Draw
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.
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.

To gain access to the driver enclosure, open the access door and remove the cover
from the enclosure. Refer to the Electrical Specifications Drawings for the access
location for your sign. For 13", 18" and 24" displays, access to the interior
components is gained by removing the screws from the hinged door. In the 36" and
48" displays, there are door latches, providing for access to the interior components
by removing the digits.
A direct controlled display uses a current loop connection from the j-box at the base
of the display to the driver enclosure in the sign. All the power and signal wiring
terminates at the driver enclosure. The DataMaster hand-held controller receives its
power from the display. The display layout is shown in Drawing A-177150.
Note: The cable from the j-box to the display needs to be routed through conduit or
the display pole to protect it from weather and vandalism.
1. Mountthe j-box near the display.
2. Rou te a 6-conductor, 22 AWG, shielded cable through conduit from the j-
box to the driver enclosure in the host display. (Distance limit from the jbox to the display is 50 ft.)
3. Connect the signal/power cable from the j-box to the driver enclosure as
shown in
A-184918 for additional information.
4. Using a DB9M to DB9F serial cable, plug theDataMaster controller into the j-box, connected to the host display driver enclosure.

3. For ad ditional operation and connection information see ED-13953:
DataMaster Modem Installation Manual.
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.

In each digit, certain LEDs always
go on and off together. 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 throughou t
the display.
The Electrical Specification Drawings specify the driver
connectors controlling the digits.
Numbers displayed in hexagons in
the upper half of each digit, as
shown in
Figure 17, indicate which
Figure 17: Digit Designation
connector or connectors are wired to that digit. Larger digits, like the 36" digits
shown in Figure 17, are each wired to two connectors. (Digits for a 48” display use
four connectors for each digit.)

6. Carefully lift the driver from the display and place it on a clean, flat surface.
7. Follow the steps in reverse order to attach a new driver.
DataMaster Rate displays may use 4-, 8-, or 16 -column drivers, depending on the
model and size of digits. Each 16-column is so named because it has 16 outputs as
compared to 8- and 4-column drivers.
Figure 18 identifies the major functions for a 4-column driver. (Major functions are
the same on the 8- and 16-column drivers.)

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
• self-test.)
• 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) on the host driver, the host driver
will display “E5,” and all client drivers will continually cycle through the power on
self-test.

Section 5: Rate Display Operation
This section describes the DataMaster 100 controller, and how it is used to set the information
on the Rate Display.
5.1 DataMaster 100 Overview
The DataMaster 100 Series controller, shown in
Figure 22, is a hand-held controller designed to
operate Daktronics LED DataMaster
console’s liquid crystal display (LCD) guides the
user through the operation of the system.
The DataMaster 100, identified by the series
number DM-100, can be configured to display
motel rates, gasoline price, and time and
temperature data. The displays in the LED
DataMaster Series will use a junction box at the
base of the sign, an indoor wire system, modem or
radio. Refer to Section 3 for information on
possible connection procedures.
For details on configuring the DataMaster to
operate a display, refer to Section 5.3: Rate Display Operation.

Dimming
The dimming level of the Rate display can be adjusted in two ways. A
temperature/light sensor, mounted near the display, can detect the level of ambient
light at the display location and dim the sign's LEDs accordingly. This function is
known as automatic dimming. When the manual dimming function is selected, the
LEDs remain at the same level of brightness regardless of the level of light detected
at the display.

The following frequently asked questions (FAQ) list was designed to provide DataTime or
DataMaster display owners with answers to common questions as well as additional
troubleshooting information. Reviewing this FAQ list before calling the Daktronics Custom er
Service Help Desk will result in a better, more complete information exchange.
Note: This FAQ refers to specific sections in following installation and operation man uals.
Q. How do I know which driver is the “host” (that is, which driver connects to the
DataMaster
A. All driver boards are identical until you install the Protocol 4 plug. The driver
containing the Protocol 4 plug becomes the host. (Refer to the section titled Power
and Signal Connection of the manual.)
Q. Which driver do I connect the temperature and light sensor to?
A. Connect the sensor to the host driver only (the driver that is connected to the
DataMaster 100 controller).
Q
. I have a price display with multiple lines. Which line do I put the host driver
on?
A. You can designate any driver as the host driver by installing the protocol plug in jack
J20. Be sure to set the line number of each driver by installing the correct address
plug. Use the Signal Out terminals of this display to go to the driver on the next line.
Connect signal to all other displays using the Signal Out terminals of the previous
line. (Refer to the section titled Power and Signal Connection of the manual.)
Q. I powered up the display for the first time, and nothing happened; no digits lit
up or anything. What’s wrong?
A. First, open the display containing the host driver (the driver connected to the
DataMaster 100 controller). Is the green LED labeled POWER illuminated? If not,
the driver is either not getting 24 V DC, or there is a problem with the power supply
circuit on the driver board. If there is 24 V DC on J17, and J17 is secure, the driver is
defective. If the POWER LED is illuminated, check the protocol and address
settings.
Check to make sure that the protocol plug is loaded in J20 of the host driver. The
protocol plug should be installed only on the host driver (the driver connected to the
DataMaster 100 controller.)
If the host driver has power and the proper protocol and address settings, it will
always display something on power-up (it may be just an error code). If this does not
resolve the problem, the driver is probably defective. You can try swapping the host
driver with one from a different display. Make sure that the host driver always has a
protocol plug installed on J20.
Q. My sign is displaying “Ex” (x is a number). What’s wrong?
A. The driver displays error codes for common problems; refer to the Troubleshooting
section of the manual to resolve the problem.
Q. My sign is displaying garbage. What’s wrong?
A. Most likely the protocol and/or address plug settings are incorrect. The protocol plug
should be installed in jack J20 only on the host driver (the driver conn ected to the
DataMaster 100 controller). (Refer to the Power and Signal Connection section of
the manual.)
Q. I don’t want to show __ (°C/°F/time) on my Time & Temp display. How do I
remove this?
A. Use the DataMaster 100 controller to set the hold time for this item to 0.0.
Q. When I try to set the hold times on my Time & Temp display to less than 1.1
seconds, it doesn’t work. Why?
A. DataTime displays with driver software versions earlier than 2.0 did not support hold
times of less than 1.1 seconds. Versions 2.0 and newer do not have this issue.
Q: I just connected my DataTime display, and instead of showing temp, it shows an
error message. What's wrong?
A: Refer to Drawing A-166883 for temp sensor jumper settings and LED indicator
information. Refer to Drawing A- 16 6 21 6 for the 4-column MASC LED driver (or
appropriate 8- or 16-column driver specifications) for troubleshooting information.
The CAN RX and CAN TX LEDs should blink once every few seconds. If both
LEDs are on constantly, suspect the wiring between the MASC LED driver and the
temp/light sensor.
Q: I have a multiple line display and all lines of the display show the information
set on the first line. How do I get the correct information on each line of the
display?
A: The line number for the display is set using address plug J19. All displays ship with
an address plug that defaults to Line 1. The install kit includes a set of 12-pin Mate-
™
N-Lok
they should be installed. If a driver is located inside a display on a line other than
Line 1, remove the Address plug and install the corresponding plug to the line of
price data you would like to show.
plugs that are labeled with the line number of the display driver to which
The following table lists problems that have been found with older versions of the
display driver software. If you see this problem, look at the version label on the
MASC driver. If the version is earlier than the one listed in the fix column, this
driver needs to be sent back for reprogramming. Contact Daktronics Customer
