Daktronics signs are built for long life and require little maintenance. However, from
time to time, certain sign components will need replacing. The Replacement Parts
List in Section 7 provides the names and numbers of components that may need to
be ordered during the life of the sign. Most sign components have a white label that
lists the part number. The component part number is in the following format: 0P-_ _
_ _-_ _ _ _ (circuit board) or 0A-_ _ _ _-_ _ _ _ (multi-component assembly).
Following the Replacement Parts List is the Daktronics Exchange and Repair
and Return Programs. Refer to these instructions if any sign component needs
replacement or repair.
1.1 Safety Precautions
1. Read and understand these instructions before installing.
2.
Be sure that the display is properly grounded.
3.
Disconnect power before working on the display.
4.
Do not modify the displays or attach any panels or coverings to the display
without the express written consent of Daktronics, Inc.
5.
Most products are equipped with a 3-wire grounding-type plug, a plug
having a third (grounding) pin. This plug will only fit into a grounding-type
power outlet. This is a safety feature. If you are unable to insert the plug
into the outlet, contact a qualified electrician to replace your obsolete outlet.
Do not defeat the purpose of the grounding-type plug.
1.2 Display Overview
The Daktronics DataTrac CE-1010 Indoor LED displays have been designed and
manufactured for performance, reliability, easy maintenance, and long life. The
displays consist of an array of LED pixels. The configuration of the LED pixels is
dependent on the family of LED displays. The standard character is seven pixels
high by five pixels wide.
The DataTrac CE-1010 system is available with DataView or Venus 1500 protocol
for message control. The PC controls one or more DataTrac sectional displays. The
displays are offered as single-face sectional displays, which are single-sided standalone units. They can be mounted side-by-side and stacked on top of each other to
create a larger display.

Introduction
DataTrac displays are character-based indoor LED displays, which are available in
ri-color (red, green and amber) characters. This display family is for 5x7 single-
t
stroke fonts. Daktronics offers the DataTrac displays with a 1.2", 2.1", 3.2", or 4.2"
character height in various lengths. The DataTrac model numbers are described as

1.3 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
reasons for this growth are many, but the need for additional features and complexity
of multiple sign installations has emerged, and the Daktronics display systems have
been designed to meet those needs. The common thread to most clients’ requests is a
means of programming and controlling a group of signs from a central control point.
Daktronics responded by developing a powerful system of interconnecting and
controlling signs. Great care has been taken to design products that will satisfy a
wide variety of installations. Some of the design goals of these systems include the
following:
• Easy transfer of messages
• The ability to tell a sign in the network which message it should run
• The ability to determine the status of any sign on the network
• The ability to control multiple sign technologies on the same network
All of the programming features would seem insignificant if the installation of the
system
s could not be accomplished with basic tools and without technical difficulty.
Daktronics decided to use the very popular and readily available RJ11 connector.
This connector is also used on modern home and office telephone equipment.
All that is required for signal installation is standard six (6) conductor modular
t
elephone wire. For some installations, it may be possible to buy pre-terminated
telephone cables for use with the displays.
The DataTrac CE-1010 display uses a RS422 networking system. RS422 (EIA/TIA422-B) is a standard com
transmission scheme, which uses a typical maximum cable length of 1.2 km
(approximately 4000 feet). The main advantage of RS422 over RS232 is the longer
cable length that is possible. A signal converter is needed to convert the computer’s
RS232 to RS422.

1.5 Daktronics Nomenclature
The X-coordinate refers to the LED block placement within a row of characters. To
count the placement of the X-coordinate, begin with the left-most LED block as X=1
and continue counting across through the entire display to the right-most LED block.
The Y-coordinate refers to the LED block placement within a column of characters.
To count the placement of the Y-coordinate, begin with the upper-most LED block
as Y=1 and continue counting down through the entire display to the bottom-most
LED block. The software on the control PC uses these coordinates to determine the
placement of data within the larger display.
The X,Y coordinates at the upper left character of each section need to be configured
for proper display orientation.
In addition, various Daktronics drawings may contain the following labeling
formats:
Finally, drawings commonly have Daktronics part numbers. You can use those part
numbers when requesting replacement parts from Daktronics Customer Service.
Take note of the following part number formats:

2.1 Support Structure Design
The wall, framing members, or structure that will support the Daktronics supplied Zbrackets and display sections are to be designed to support the weight of the
completed system. Review all drawings to determine special requirements and the
total system weight. It is the customer’s responsibility to ensure that the installation
will meet local codes and or standards. Daktronics is not responsible for the
installations or the structural integrity of support structures done by others.
Mechanical Installation
2-1
2.2 Z-Bracket Installation for Sectional Display Mounting
Review all drawings to determine special requirements. Display sections are to be
mounted to a wall or structural frame using Z-shaped aluminum brackets provided
by Daktronics in an installation kit. The Z-brackets allow for one (1) inch of air
space behind the displays for power and signal terminations, and for the
corresponding customer supplied junction boxes. Installation drawings will provide
the necessary dimensions for the mounting of the display, Z-brackets, and power
termination junction boxes.
It is the customer’s responsibility to attach the Z-brackets with the correct am
and type of hardware to support the weight of all display sections mounted to those
Z-brackets as well as the support structure mentioned in Section 2.1. It is the
customer’s responsibility to ensure that the installation will meet local codes and or
standards. Daktronics is not responsible for the installations or the structural
integrity of support structures done by others.
When mounting a display system containing one or multiple rows of display
sectio
ns, the bottom row of displays will require two rows of Z-brackets attached to
the support structure. Upper rows of displays will require only one row of Z-brackets
per row of displays. This is due to the fact that each display section has alignment
pins located on the top of the section that interlo c k into the bottom of the display
section stacked on top of it. It is important to check these pins for tightness before
hanging a display section.
ount
2.3 Electrical Junction Box Installation
Review all drawings to determine special requirements. Installation drawings will
provide the necessary dimensions for the power termination junction boxes. The
contract specific riser diagram will identify power specifications for the display
system. Also read Section 3 for any other pertinent information that may be needed
during the mechanical installation process.
2.4 Hanging Display Sections
Each DataTrac CE-1010 section has threaded insert nut holes on the rear side for the
attachment of mounting brackets. These are required for the hanging of the
individual sections. The mounting brackets come in the installation kit along with
the required ¼-20x3/4 hex head bolts. A drawing or drawings showing the correct
mounting bracket attachment will be included in the installation kit. Drawing A-
155773 illustrates the attachment of mounting brackets.
Hang the section that receives the incoming signal to the bottom
mounted Z-brackets. Subsequent sections are to be mounted to the Z-brackets, as
they are daisy-chained together with signal interconnects per the contract specific
riser diagram and Section 3 for electrical and signal information.

2.5 Display Ventilation Requirements
Fresh air inlets and exhaust vents should not be obstructed in any way. Using the
Daktronics suggested mounting methods will ensure proper ventilation. If using a
different mounting method, consult a Daktronics sales representative for clearance
requirements regarding the particular display. If ventilation requirements are not
met, the display warranty will be void.

Section 3: Electrical Installation
3.1 Signal
Cables
The conductor connector used in the
network is an industry standard 6-pin
RJ11 or an 8-pin RJ45. This
connector can be found on many
telephones and LANs.
The cable used in the network is a
standard flat six-conductor telephone
cable (standard flipped cable). Refer
to Figure 4. This cable has one end
that is the mirror image of the other end (i.e. the cable is flipped). Refer to Figure 5
for a standard flipped cable.
Notice in Figure 5 that the color code on one connector must be made the opposite
on the other connector. When installing a network, it is not easy to remember in
which direction the previous end was oriented. One simple way to avoid confusion
is to standardize the color code, having one color for the connector going into the
output of a sign, and the opposite color for a connector going into the input of a
sign. This will help ensure correct cabling since cables are always installed from the
output jack of one sign to the input jack of the next sign.
Figure 4: Six conductor RJ11 Connector and
Cable
Figure 5: Flipped Cable with RJ Connectors
Installing an RJ11 Connector
Installing an RJ11 connector on the end of the sixconductor cable is a simple task when the correct tools are
used. The RJ11 crimping tool (Daktronics part number TH-
1033) performs two separate steps.
First, use the crimping tool to strip the outer insulation from the inner wires. This
does not result in bare wires since only the gray outer jacket is removed. After
correct stripping, the wire will appear as shown in Figure 6.
Electrical Installation
Figure 6: Wire with Outer
Jacket Stripped
3-1
The crimping tool is then used to crimp the RJ11 connector onto the cable. The RJ11
connector is locked into a special socket in the tool. The stripped wire is inserted
into the RJ11 connector. Finally, the tool is squeezed like a pliers to crimp the
connector onto the wire. This completes the installation of an RJ11 connector onto
the wire.
3.2 Power
Reference Drawing:
Generic; System Riser Diagram..................................Drawing A-113523
Power Requirements
Each display system comes with a contract specific riser diagram similar to the
drawing referenced above.
Refer to the specifications sheet for voltage and current requirements. The displays
accept a universal input voltage of 85-265 VAC at 50 or 60 Hz.
Do not connect the display to any voltage other than that listed on the Daktronics
product label attached to the back of the display.
Grounding
Proper grounding is necessary for reliable equipment operation, and provides some
protection to the equipment from damaging electrical disturbances. All of the
displays are supplied with a power cord that contains an earth ground conductor.
Make sure to plug this cord into a grounded outlet. If the proper grounding methods
are not followed, the warranty will be void.
Note: Displays must be earth grounded according to national and local electrical
codes.
3-2
Power Connection – Pluggable Cord Connected Displays
The DataTrac CE-1010 displays are
supplied with an eight (8) foot power cord.
The socket-outlet should be installed near
the equipment and be easily accessible.
Plug the power cord into the socket as
shown in Figure 7.
It is important to check this connector to
make sure it is fully secured before
hanging a display section.
Figure 7: Power Cord Connection
Electrical Installation
3.3 RS422 System
A RS422 system requires a signal converter to connect the first sign to the computer.
1. Plug the serial cable’s 25-pin connector into the signal converter.
2. Plug either the 9-pin or the 25-pin connector (depending on your PC) into
the RS232 COM port to be used.
3. Plug the signal converter’s power cord into a 120 VAC grounded outlet.
4. Plug a flipped phone cable into the “RS422 OUT” of the signal converter
and the opposite end into the “RS422 IN” of the first display.
The “RS422 IN” jack’s pin out is as
follows:
Pin Function

2 D1OUT-P
3 D1OUT-N
4 D1IN-P
5 D1IN-N
6 N.C.
Figure 8: Output Signal Cable Connection
3.4 Sign to Sign/Section to Section Connections
When wiring the sign to sign network, the cable and connectors discussed earlier in
this section are used. Pay special attention to the information regarding flipped
cables to help ensure a successful installation. The best method of wiring the signs
together is to start at the first sign, as it is designated to begin the n etwork.
1. Plug the cable into the “SIGNAL OUT” output jack of the first sign (refer
to Figure 8) and the other end of the cable into the input jack of the next
sign.
2. Continue this procedure throughout the network. When the wiring is
complete, the last sign will have nothing in the output jack.
3. Before hanging the displays, review Section 2.4.

Maintenance and Troubleshooting
4-1
4.1 Accessing the Interior of the Display
Depending on the overall size of a
display system, sectional displays may
have two sizes of front access
removable panels. Finding the
Daktronics labels on the front of the
display will help in locating the lower
right corner of a display section.
For 1.2" and 2.1" display types, the
module in this corner may either be a
4x6 or 4x12 panel. For 3.2" and 4.2"
displays, the modules are all 2x6
panels. Panels are removed by
accessing ¼-turn fasteners in the
corners of a module panel.
Note: Not every hole has a ¼-turn
fastener. Only the four corner holes of
the module panel do. Refer to Figure
9.
The screwdriver must pass through the
face panel. The ¼-turn screws are
located behind the face panel.
Using a #1 Philips screwdriver, turn
the 4 ¼-turn screws securing the LED
module panel to the cabinet of the
display one-quarter turn counterclockwise. Refer to Figure 9 and
Figure 10. The screws are designed to
remain in the LED module flanges,
but release from the cabinet.
Gently pull the LED module panel
from the body of the display. It will

4.2 Display Interior
Once the LED module panel is removed, the display interior is visible. Various
internal components, including the display controller and the power supplies, are
now accessible for repair or replacement.
LED Module Replacement
If any LED modules fail, the recommended
procedure is to replace the failed module,
send it to Daktronics, or send it to a certified
dealer for repair. Refer to Section 4.6 for
information on packaging components for
shipment.
To remove an LED module:
1. Remove the appropriate LED
module panel as described in
Section 4.1.
2. Disconnect the remaining 40-
pin ribbon cable from the failed
module.
3. Removing the wire cloth retainer frame requires the following: For 1.2"
displays, remove the four nuts located along the rear edge of the LED
circuit board. For the 2.1" displays, remove the four perimeter nuts and
one in the center of the circuit board. For the 3.2" and 4.2" displays,
remove the six perimeter nuts and two in the center. Refer to Figure
13.
4. Flip the module panel over and remove the wire cloth filter from the
front of the failed module.

Power Supply Replacement
1.2" and 2.1" Power to the LED modules is
provided by small 5V power supplies. Each
power supply can support two 4x6 modules.
The controller board also requires a 5V power
supply. The power supplies are mounted to the
back sheet within the display cabinet.
3.2" and 4.2" Power to the LED modules is
provided by 6.5V power supplies. Each power
supply can support two 2x6 modules. The
controller board also requires a 5V power
supply.
Figure 15: Power Supply
To remove a power supply that has failed, first
remove the LED module in front of the failed
power supply as described in Section 4.1.
Each power supply is attached to a power
supply plate by two metric screws. The plate is
secured to the back sheet by two (2) #6 hex
head screws. Refer to Figure 15. Use a
3
/16-nut
driver to remove the #6 hex head screws.
Lift the power supply and plate back. The
metric screws securing the power supply to the
Figure 16: Power Supply Cable Connections
plate are now accessible. Use a #1 Philips head screwdriver to remove the screws and
free the power supply.
Disconnect the power cables as shown in Figure 16. The power supply is now fully
released and ready for replacement. Follow the previous steps in reverse order to reattach
the new power supply. Refer to the display’s schematic for the proper wiring

Maintenance and Troubleshooting
Display Controller
The display controller is mounted to the inside rear of the display cabinet. Refer to
Figure 17 for an illustration of the controller and the appropriate schematic for its
location in the display. The controller receives information from the computer, interprets
it, and activates the appropriate LEDs on the display. The display controller also has a set
of eight switches by which an address can be set using standard binary code (refer to
Section 4.3).
Figure 17: MDC Controller
Under normal operation, the normal state of the controller’s status indicator LEDs is as
follows:

To replace a failed controller:
1. Remove the module panels as described in Section 4.1. Each display section has
one controller mounted inside it. Refer to the appropriate schematic for the
controller location.
2. Disconnect the power cable and signal ribbon cables. Release the power cable
by squeezing the tabs on each side of the connector. Release the signal ribbon
cables by spreading the clasps on the jack and gently pulling up on the ribbon
cable. Take note of the signal cables and their appropriate jacks.
3. Remove all #6 connecting screws and the controller will be free. If the address
switches are used, take note of the switch configuration and set the same address
on the new controller.
4. To install a new controller, reverse the previous procedure.

4.3 Controller Address and Test Mode
The controller has a set of “DIP” switches on
the side of the controller as shown in Figure
18. These DIP switches set the hardware
address. When replacing a controller board,
be sure to set the DIP switches in the same
address configuration as the defective
controller. Turn power off and then back on to
recognize the new address.
Note: Setting the DIP switches to address 0
(turn all the switches to OFF by flipping them
toward the printed switch numbers) can
activate a test mode. The display’s power
must be downed and then reconnected to run
the test mode.

to conduct the test.
The Network cable tester is used to test for two things:
1. A flipped RJ11 cable used instead of a straight through cable.
2. A good connection from a computer or signal converter to a through the connecting
cable.
The use of a flipped (reversed) or straight cable can be determined visually. Use the figures
below as a guide, or use the Network Cable Tester box for assistance.
Figure 7) is provided

Conducting the Venus 1500 Software Test
1. Open Venus 1500 Administrator.
2. Click Network Configuration and open the direct network by clicking on the [+] in
front of Direct Network.
3. Right click the network you want to test.
6/30/2004
ED-14413
Page 6
4. Click [TEST].
5. If the Transmit LED on the signal converter flickers, the signal is getting to the
signal converter. That means that the right Com port is being used. However, if it
does not flicker, the computer has either a software or hardware problem.
6. If you get the same message in the “Received” box as in the “Sent” box, the loop-
back test was successful, implying that the cable has continuity to the point of the
connection.
Note: Flipped and straight cables will provide the same results. Check for correct
order of the wires.
7. If “No Response” appears in the “Received” box, the test failed due to one of the
following problems:
a. The correct computer COM port is not being used, or USB port is not
configured as a “serial” port. (If the Transmit LED flickered, this was not
the problem.)
b. A communication problem exists:
• The fiber or the ends on the fiber are bad.
• (or) The wire or the terminations are bad.
c. There was a problem conducting the test:
• The serial cable to the signal converter is bad or not plugged in.
• The signal converter is not plugged in.
8. If the words “It appears as if this port has a modem attached” appear, the modem will
need to be moved, or you need to use a different COM port.
After the test is complete:
1. Remove the wire jumpers and make sure terminations are correct.
2. (or) Remove the fiber splice, and reconnect fiber to fiberboard.
3. Run the test again without the jumpers, splice, or loop-back box. The test should
fail.
4. Use Venus 1500 Display Manager to receive the status to ensure communication
now works correctly.
