Installation, Temp Sensor, G3 .................................................................Drawing A-184840
Shop Drawings .....................................................................................Refer to Appendix A
All displays in the DataTime® series use a light sensor to regulate dimming functions and a temperature
sensor to collect and display temperature information. Both temperature and light-monitoring electronics are
located in the sensor housing, shown in Figure 2.
The Daktronics Controller Area
Network (CAN) Temperature/Light
Sensor is pre-installed in a protective
housing. The assembly includes the
sensor, mounting bracket, and cabling
with a quick-connect plug. Instructions
that follow describe the placement
and connection of the device. Review
the wiring diagram and connection
illustration in Drawing A-184840 before
beginning.
Dimming involves decreasing overall
display intensity, both for better display
viewing and to prolong LED life. Set the
brightness level highest during the day
to compete with daylight, and lower at night.

Recommendations and Requirements:
• First choice for the sensor location is a north eave or northern exposure, away from direct sunlight
and above grass. This location gives extra stability and accuracy to the sensor because of the
additional shade usually provided by a northern exposure.

Mounted Under North Eave
• Second choice for locating the sensor is on the display itself, or somewhere on the display structure.
(This works best with light-colored displays.) Locate the sensor above, below, or on the northern edge
of the display to keep the sensor shaded as much as possible. Sensor readings are more accurate if
there is grass below the sign, rather than concrete or asphalt.
Things to Avoid:
• The sensor requires a location away from chimneys, air conditioners, vents, tar roofs, concrete, and
parking lots, all of which can cause abnormal temperature fluctuations and incorrect sensor readings.
For accurate readings under these conditions, keep a separation of at least 20-30 feet horizontally and
8 feet vertically between the sensor and the influential element.
• Locations that restrict air movement are also unsatisfactory.
• When a display has two faces, do not mount the sensor between the faces.
Connecting the Temperature Sensor
After properly locating the sensing device, follow these steps to connect it with the display:
1. The temperature sensor is equipped with outdoor-rated cable that has a four-pin quick-connect plug
on the end. Route the cable from the sensor to the back of display.
2. A four-pin quick-connect jack located on the back panel of the display connects the sensor cable to
the display. Refer to the Shop Drawing for the exact location of the jack on a particular model. Simply
plug in the sensor cable and tighten the connector collar to the display. A factory-installed internal
cable, runs from the sensor jack to the TB1 connector on the driver inside the housing.
Mechanical Installation 5
3. Secure any additional cable to prevent the quick-connect plug from being pulled out of the display
and to protect it from weather or vandalism.
Note: The temperature sensor is equipped with 25 feet (7.6 m) of cable. If necessary, the cable can be cut to
shorten and then be re-terminated. In addition, the cable can be extended by using a four-conductor shielded
cable to a distance of 750 feet (230 m). When not using the provided weather-resistant cable, the cable from
the sensor to the display needs to be in conduit.
Connection to the Sensor
If it is necessary to reconnect the wires to
the temperature sensor terminal block,
refer to Figure 6 and the table for the
correct connections.
Note: Make sure the power is off before
making any connections.
Connection from Sensor to the
Display Driver
If the distance from the temperature
sensor to the display is greater than the
provided 25 foot (7.6 m) cable, connect a 4-conductor shielded
cable from the sensor to TB1 on the display driver board.
1. The display’s power must be OFF when attaching the
internal sensor cable to the host driver.
2. Connect the temperature sensor to the terminal
block (TB1) on the host driver. Refer to Figure 7
and the table for the correct
connections.

Section 3: Electrical Installation
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. Improper installation
could result in serious damage to the equipment and be hazardous to personnel.
3.1 Preparing for Power/Signal Connection
Reference Drawing:
Time & Temp Power/Signal Hookup ....................................................... Drawing A-938369
Electrical installation consists of the following process:
• 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 display location.
• Routing the control signal cable from the control location to the display location.
Drawing A-938369 provides detailed instructions for power and signal connections for time and temperature
displays, including connection of the temperature sensor and connections between host and client displays.
Refer to this drawing before completing any part of the electrical installation.
3.2 Power Connections
Daktronics DataTime® displays have removable or hinged front panels that allow access to the digits, cabling,
and other electronic components.
DataTime® outdoor displays require a dedicated, 120 V circuit (or 230 V for international use) for incoming
power. The display itself has no breakers or fuses.
WARNING: The display circuit must be fused at 15 A, and all conductors must be designed to pass a 15 A
current in normal operation. Failure to meet wiring and over current protection device requirements is a
violation of the National Electrical Code and will void the display’s warranty.
3.3 Grounding Connections
Reference Drawing:
Enclosed Driver, 4 Column Reference ....................................................Drawing A-938300
Displays MUST be grounded according to Article 250 of the National Electrical Code and according to
Daktronics specifications or the warranty will be void. Daktronics requires a resistance-to-ground of 10 ohms
or less.
The contractor performing the electrical installation must verify ground resistance. Technicians from
Daktronics Sales and Service offices can also provide this service.
Proper grounding is necessary for reliable equipment operation. It also protects the equipment from
damaging electrical disturbances and lightning. Drawing A-938300 illustrates where to connect the ground
wire at the driver enclosure.
Electrical Installation 7
Important points about grounding:
• Follow local and national codes: The material of an earth-ground electrode differs from region to
region and from conditions present at site. Consult any electrical codes that apply.
• Support structure cannot be used as an earth-ground electrode: Daktronics does not recommend
using the support structure as an earth-ground electrode; concrete, primer, corrosion, and other
factors make the support structure a poor ground.
• Note: The support structure may be used as an earth-ground electrode only if designed to do so. A
qualified inspector must approve the support structure and grounding methods.
• One grounding electrode for each display face
3.4 Power Installation
There are two types of 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. In this
circumstance, do not connect neutral to ground at the disconnect or at the display as this would violate
electrical codes and void the warranty.
Use a disconnect so that all ungrounded lines can be disconnect. The National Electrical Cod 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, observe the
following guidelines:
• 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.
3.5 Lightning Protection
Using a disconnect near the display to completely cut all current-carrying lines significantly protects the
circuits against lightning damage. For this system to provide protection, disconnect power when the display
is not in use.
Disconnect the DM-100 control console 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 DM-100 console’s circuitry.

Reference Drawings:
Multipurpose 4 Column LED Driver II Specications ..............................Drawing A-166216
Host/Client Denitions ............................................................................. Drawing A-185236
One driver at each display installation is designated
as the host driver, and all other displays are clients.
The Signal OUT terminals on the host are used to
connect to the client drivers. Refer to Figure 12 and
Drawing A-185236 for an illustration of the client/
host display connection.
12 Electrical Installation
Client drivers receive signal from the host driver on
Figure 12: Host, Signal Out to Client, Signal In
the Signal IN terminals and can re-drive this signal to other client drivers on the Signal OUT terminals.
The maximum wire distance between the host driver and client driver is 2,000 feet.
Some multiple-module DataTime® displays use host/client displays, which do not contain a driver and may
use either client or host digit outputs. The DF-1012 model uses the host/client configuration.
Address Settings
The address of each driver is set using an eight-position DIP-switch
(S1), and the address is based on that driver’s position in the display
system. If a single-line display 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.
Note: Some older drivers set the address of each driver using an
address plug (Daktronics part # 0A-1150-0122) in J19. The address,
either using a switch or a plug, needs to be set for each driver.

• Incorrect connection from driver to digits.
16 Maintenance and Troubleshooting
Error Codes
Some DataTime® displays have their own built-in troubleshooting mechanism. Failures that occur in the
display driver use codes. If a display malfunctions, a failure code registers by showing an Ex value on the first
two digits of the display. E indicates an error, and x represents the code number. Refer to the following table
for a description of each failure code and for possible solutions.
Note: The LCD screen on the DM-100 controller will not show the following failure codes. Failure codes are
only shown on the DataTime® display.
Failure Code Description Possible Solution
E1
E2
Protocol Setting Error: There is an unsupported
driver protocol setting.
Time Error: No valid time is stored in the driver; it
may be a failure of the real-time clock on board or
other timekeeping device.
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 DM-100 controller.
Check the temperature sensor location and verify
all connections. Refer to Section 2 for wiring
information.
E3
E4
E5
Temperature Error: No response coming from
the temperature sensor, or general temperature
sensor failure.
No Message Error: This code is shown when no
messages are downloaded to the display
No Line Number Selected Error: The driver for
this line has a Protocol-4 plug installed in J20, but
the address is not set on the address switch.
Note: The temperature sensor takes about 10
seconds to initialize on power up. The display
shows this error until initialization is complete
If a temperature sensor is not used, set the hold
time to zero.
Download a new message to the display using
the DISPLAY SEQUENCE key on the DM-100
controller.
Set the line number by setting the address
using the address switch. The Protocol-4 plug
designates this driver as the “host.” If this is not
the host, remove the Protocol-4 plug from J20.
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 display
Ad momentarily, and the first digit flashes three
numbers indicating the decimal address set with
the address switch. (If a client driver display’s
A <number>, followed by P <number>, it is not
receiving signal in, and is performing its own self-test.)
Driver Firmware Version
Address
Line number
Columns
(r:XX)
(Ad:XX)
(L:X)
(1234)
• The first two digits of each line display Lx, where x is the line number that the driver is set to control
using the address switch (set with address plug on older drivers).
• Each line displays 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 is set, or the driver or digit harness is connected
incorrectly.
If no address is set on the host driver, it will display E5, and all client drivers will continually cycle through
the power on self-test.

Section 7: DM-100 Controller
These sections describe the DM-100 controller including the insert and the operation to set the time and date on the
display.
7.1 DM-100 Overview
Reference Drawing:
System Riser Diagram, Control Combinations .......................................Drawing A-164988
The DM-100 Series controller, shown in Figure 19, is a handheld controller
designed to operate Daktronics LED DataTime® and DataMaster
displays. See Section 2.1 for the list of displays the DM-100 can control.
The console’s liquid crystal display (LCD) guides the user through the
operation of the system.
Time and temperature displays use a junction box at the base of the
display or an indoor wire system. Refer to Section 3 for information and
possible connection types.
Note: You must be connected to the display in order to modify the time,
temperature, hold time, etc. The following sections will explain this
process in greater detail.
7.2 DataMaster Insert
Reference Drawing:
Insert, LL-2551 Price/T&T Display ..........................................................Drawing A-164998
The DM-100 controller uses a keypad insert to program time and temperature information for the displays.
To see more detail on the DM-100 insert, refer to drawing, A-164998. If an insert is lost or damaged, a copy of
the insert drawing can be used until a replacement is ordered.
To start the controller and use the insert, read the section carefully to fully understand the operating
instructions.
Note: Depending on the version of the DM-100 controller and the revision on the display, some of the
following items may not be used on the display, or will not be shown on the DM-100 controller.
7.3 Time & Temperature Display Operation
The DM-100 controller can be configured to program time and temperature information displayed on the
LED DataTime® Time & Temp display. The instructions provided in this section discuss the functions the
operator uses to control the display. In the unlikely event that the Time & Temp display malfunctions, refer to
Section 4.2 for troubleshooting actions that may be taken.
Figure 19: DM-100 Console
Connect to the display through either the indoor or outdoor J box, set the time and date and send changes to
the display.
Note: You will need to do this infrequently, since the display will automatically keep track of time. The time
on the display should be accurate (even through a loss of power for several days). Use this function when a s
DM-100 Controller 27
has just been installed or to correct time due to long power outages.
There is more than one way to get to certain LCD screens on the DM-100. One way is by using the menu and
then using the arrows to reach the desired location, and the other is to set the time, date, and then continuing
to enter through to the additional screens.

Glossary:
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. This is only a brief overview. Refer to Section 4 for additional information on maintaining the
various display components.
Client: Receives signal from the host driver on the Signal IN terminals. These drivers can re-drive signal to other
client drivers.
DataMaster Controller (DM-100): The handheld keypad device used to set the time, date, hold times, dimming etc.
on the DataTime® display. Refer to Section 6 for more information on the DataMaster controller.
Display Address: An identification number assigned to each driver in a network. The address is set using an
8-position binary switch. For single-line signs such as a Time & Temp display, the address will typically be “1.” The
address will be displayed each time the display powers up.
Digit Circuit Board: The board mounted to the back of a digit panel and containing the LEDs. It can be made up of an
entire digit or as individual segments of a digit.
Host: Contains the driver which relays signal directly from the DataMaster controller on its Signal IN terminals. It is
the only driver connected to the temperature/photo sensor. The Signal OUT terminals are used to connect to client
driver. The host driver is selected by inserting the Protocol 4 plug into the protocol jack.
Light emitting diode (LED): High-intensity, low-energy lighting units.
Power Supply: Converts AC line voltage from the load center to low DC voltage for one or more digit circuit boards.
Protocol plug: A plug inserted in the 5-pin protocol jack to select the host driver for a set of host-client displays.
