time to time, certain sign components will need replacing. The Replacement Parts List
in Section 4.7 provides the names and part 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-_ _ _ _-_ _ _ _
(component) or 0A-_ _ _ _-_ _ _ _ (multi-component assembly).
Following the Replacement Parts List is the Daktronics Exchange and Return and Repair Programs in Section 4.8. Refer to these instructions if any sign component
needs replacement or repair.
1.1 Safety Precautions
Important Safeguards:
1. Read and understand these instructions before installing.
2. Be sure the sign is properly grounded.
3. Disconnect power when servicing the sign.
4. Do not modify the sign structure or attach any panels or coverings to the
sign without the written consent of Daktronics, Inc.
5. Mostproducts are equipped with a 3-wire grounding-type plug having a
third (grounding) pin. This plug will only fit into a grounding-type outlet.
This is a safety feature. Do not defeat the purpose of the grounding-type
plug.

Introduction
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. The
reasons for this growth are many, but the need for additional features and the
complexity of multiple sign installations has emerged. Daktronics display systems
are designed to meet those needs. The common thread to most client requests is a
means of programming and controlling a group of signs from a central control point.
Daktronics responded by developing a power 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 or group of signs in the network which message
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
In order to avoid technical difficulties, Daktronics uses the popular and readily
available RJ11 connector. This connector is also used on modern home and office
telephone equipment, allowing for easily understood installation procedures.
All that is required for signal installation is standard six (6)-conductor modular
telephone wire and a tool to install the connector. Tools required for mounting the
display depend on the location and size of the display. For some installations, it may
be possible to purchase pre-terminated telephone cables for use with the displays.
There are four (4) network systems available: RS232, RS422, modem and TCP/IP
(Ethernet).
RS232 Network
RS232 (EIA/TIA-232-E) is a standard communication interface that employs a
single-ended serial transmission scheme. The RS232 uses a maximum cable length
of 7.6 meters (approximately 25 feet). This interface was designed for computer
communication at short distances. The computer used will require an RS232 serial
communications port. Refer to Section 3 for additional information.
RS422 Network
RS422 (EIA/TIA-422-B) is a standard communication interface that utilizes a
differential balanced transmission scheme, which uses a typical maximum cable
length of 1.2 km (approximately 4,000 feet). The main advantage of RS422 over
RS232 is the longer cable length. A signal converter is needed to convert the
computer’s RS232 to RS422. Refer to Section 3 for additional information.
Modem Network
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 the control computer and display. Refer to
Section 3 for additional information.
Introduction
1-3
TCP/IP Network
The TCP/IP protocol is an interface allowing the Ethernet network card (installed in
the operator’s computer) to communicate with the display via a Local Area Network
(LAN). Refer to Section 3 and Appendix D for additional information.
1.3 Display Overview
The Daktronics 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 LED pixels is dependent on the family of
LED displays.
A typical display system consists of a Windows
running Venus
single-face units, which are single-sided stand-alone displays.

1.4 Component Identification
The following illustrations depict some of the more commonly accessed Galaxy sign
components. Because Daktronics occasionally alters standard design to meet
customer needs, the actual sign design may vary slightly from the illustrations listed.
This is only a brief overview. Refer to Section 4 for more detailed information on
maintaining and troubleshooting various sign components.
Controller: The display’s controller is the “brains” of the display. The controller
receives, translates, and activates the signal information from the control computer
to the appropriate pixels on the sign accordingly.

Introduction
Figure 2: MDC Controller
LED (light emitting diode): Low energy, high intensity lighting units.
Pixel: Each circle on an LED block represents one pixel. Each pixel is made up of a
red and green LED which when both lit creates the amber color. For monochrome
displays, only a red LED is used in each pixel.
Display/Driver Module: The module shown in
Figure 3 is 16 pixels high by 32
pixels wide. Each is individually removable from the front of the sign. The LED
pixel blocks are mounted directly onto the module board. The driver is responsible
for the switching and intensity levels of the LEDs.

signs.
Network: Consists of multiple signs connected to each other. Up to 240 Venus 1500
controlled displays can exist on one network.
RS232: Standard PC communication type with a maximum cable length of 25 feet
(7.62 meters).
RS422: Standard differential communication type with a maximum cable length of
4,000 feet (1.2 kilometers). A signal converter is required to convert the comuter’s
RS232 signal to RS422.
Introduction
1-5
Serial Port: An actual serial port is required for direct connections from the
computer or those through a signal converter. Certain USB adapters create an
“actual” serial port and others create “virtual” ports. The Venus 1500 software will
not recognize a virtual port; therefore use of a USB adapter is not supported by
Daktronics.
Serial Server: Device used to obtain information from a
LAN and convert it to a serial signal. The communication
protocol used is called TCP/IP.
Sign Address: Identification number assigned to each sign
of a network. Flipping DIP switches on the controller sets the
sign address. The control software uses the address to locate
and communicate with each sign, but signs on the same
network cannot have the same address.
Signal Cable Tester: Used to test the cable connections and
data communications through an RJ11 jack.
Signal Converter: Daktronics supplied unit that converts the
data from RS232 to RS422, or RS232 to fiber optic signal.
The signal converter is connected to the control PC via a
straight though serial cable. The RS232 to RS422 signal
converter is shown in
Figure 4.

Introduction
The label “A” on a drawing typically denotes an assembly. An assembly can be a
single circuit board or a collection of components that function together, usually
mounted on a single plate or in a single enclosure. Assemblies are divided into two
types: those that route signal and those that route power.
In addition, the following labeling formats might be found on various Daktronics
drawings:
• “TB_ _” represents a termination block for power or signal cable.
• “F_ _” stands for a fuse.
• “E_ _” indicates a grounding point.
• “J_ _” symbolizes a power or signal jack.
• “P_ _” identifies 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:
• “0P-_ _ _ _-_ _ _ _” denotes an individual circuit board, such as a driver
board.
• “0A-_ _ _ _-_ _ _ _” represents 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-_ _ _ _” shows a wire or cable. Cables may also carry the assembly
numbering format in certain circumstances. This is especially true of ribbon
cables.
• “F-_ _ _ _” indicates a fuse.
Most circuit boards and components within this sign
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 4.7, use the label
to order a replacement. A typical label is shown in
Figure 7. The part number is in bold.

Section 2: Mechanical Installation
Note: Daktronics does not guarantee the warranty in situations where the sign is not
constantly in a stable environment.
Daktronics engineering staff must approve any changes made to the display. If any
modifications are made, detailed drawings of the changes must be submitted to Daktronics
for evaluation and approval, or the warranty may be void.
Daktronics is not responsible for installation or the structural integrity of support
structures done by others. It is the customer’s responsibility to make sure that a qualified
structural engineer has ensured the structure and any additional hardware.
2.1 Mechanical Installation Overview
Because every installation site is unique, there is no single Daktronics-approved
procedure for mounting the Galaxy signs. The information contained in this section
is general information only and may or may not be appropriate for your particular
installation.
A qualified individual must make all decisions regarding the mounting of this
sign.
Read both the mechanical and electrical installation sections of this manual
before beginning any installation procedures.
2.2 Support Structure Design
Daktronics recommends either a wall mount or a hanging mount method.
Remember to have all mounted displays inspected by a qualified structural engineer.
Daktronics is not responsible for the installation or the structural integrity of
support structures done by others.
2.3 Display Ventilation Requirements
Fresh air inlets and exhaust vents should not be obstructed in any way. To ensure
proper ventilation, use the Daktronics suggested mounting methods. Consult a
Daktronics sales representative for clearance requirements regarding your particular
display if you are using a different mounting method. If ventilation requirements are
not met, the display warranty will be void.
The Galaxy Series Display has two pre-drilled holes in the top of the display for use
in the hanging mount method. Refer to Drawing A-107655 and the directions below
to hang the display.
1. Remove the two retaining screws from the
top of the display using a Philips
screwdriver.
2. Slide the provided sealing washer over the
threads of each eyebolt.
3. Insert the eyebolts in to the pre-drilled
holes on the display (refer to
4. Hand-tighten the eyebolts.
Note: Hanging the display without using the
supplied eyebolts will negate the warranty.
Attaching or hanging anything from the display will
render the warranty null and void.
The Galaxy has holes on the back of the display for the attachment of the wall
mounting clips. Using the #8-32 screws provided with the display, attach the
mounting clips to the rear of the display as shown (refer to both

Section 3: Electrical Installation
Only a qualified individual should terminate power and signal cable within this
Daktronics sign.
The Daktronics engineering staff must approve any changes made to the sign. Before altering
the sign, submit detailed drawings for the proposed modifications to the Daktronics
engineering staff for evaluation and approval, or the warranty will be rend ered null and void.
3.1 Common Connectors in the Sign
The power and signal connections in the signs use several different types of
connectors. Take special care when disengaging any connector so as not to damage
the connector, the cable or the circuit board.
When pulling a connector plug from a jack, do not pull on the wire or cable; pull on
the jack itself. Pulling on the wires may damage the cable and connector.
The following information presents some common connectors encountered during
sign installation and maintenance:
1. Ribbon Cable Connectors:
Figure 11 illustrates a typical ribbon cable connector. To
disconnect the ribbon cable, push the plastic clips on the
sides of the jack inward.
Before replacing a ribbon cable connector, spray it with
DeoxIT
may cause signal problems. In addition, apply a generous
amount of CalLube
inserting it into the jack. This paste will protect both the
plug and the jack from corrosion.
2. Termination Blocks:
Termination blocks are usually used to connect internal
power and signal wires to wires of the same type coming
into the sign from an external source. Power wires need to
have one-half inch of insulation stripped from the end of
the wire prior to termination. Tighten all screws firmly to
ensure a good electrical connection. Refer to

3. Phoenix™-Style Connectors:
Phoenix-style connectors, which are usually green, are used
for the external temperature sensor termination to the
display. Refer to
Figure 13. Strip one-quarter inch of
insulation from the wire prior to termination. To remove a
wire, turn the above screw counter-clockwise to loosen the
connector's grip on the wire. To insert a wire, push the bare
wire into the connector, and turn the above screw clockwise
to lock the wire into place.
4.Mate-n-Lok™ Connectors:
The Mate-n-Lok connectors found in the signs are white and
come in a variety of sizes.
Figure 14 illustrates a four-pin
Mate-n-Lok connector. To remove the plug from the jack,
squeeze the plastic locking clasps on the side of the plug and
pull it from the jack.
5. Phone Jacks (RJ11/RJ45 Connectors):
RJ11 and RJ45 connectors are similar to the telephone and
network connectors found in homes and businesses cables.
In order to remove this plug from the jack, depress the small
clip on the underside of the plug. Before replacing an RJ
connector, spray it with DeoxIT
any foreign matter that may cause signal problems. In
addition, apply a generous amount of CalLube
paste to the plug before inserting it into the jack. This paste
will protect both the plug and the jack from corrosion.

Cable Types
The conductor connector used in the network is an industry standard, 6-pin RJ11.
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

s
Notice in
Figure 16 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 16: Flipped Cable with RJ Connector
Installing an RJ11 Connector
Installing an RJ11 connector on the end of the six-conductor 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
Refer to the Shop Drawings listed in this section for voltage and current
requirements. A 120VAC single-phase outlet powers the displays.
Do not connect the display to any voltage other than that listed on the Daktronics
product label attached to the back of the display.
The display system must be connected to earth-ground. Proper grounding is
necessary for reliable equipment operation. It also protects the equipment from
damaging electrical disturbances and lightning.
Electrical Installation 3-3
3.4 Grounding
Proper grounding is necessary for reliable equipment operation and provides some
protection to the equipment from damaging electrical disturbances. The displays are
supplied with a power cord that contains an earth ground conductor. Make sure to
plug this cord into a grounded outlet. The display must be properly grounded or
the warranty will be void.
Note: Displays must be earth grounded according to local electrical code.
The Galaxy 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 back of the display as shown in
Figure 18.

via RS232, RS422, modem, or Ethernet signal to the first display.
2. The input signal to the display is connected to the display controller. From
the controller, the signal then travels over one or more 40-conductor ribbon
cables (J1 through J3 provide signal out) to J2 on the driver of the first row
of modules in the display.
3. Data exits at J1 and is relayed to J2 of the next module and so on, traveling
down the entire row of modules. The modules use this display data to
control the LEDs.
4. For multiple displays or a display network, an RS422 RJ11 cable relays
signal between the first display and the second display.
The power routing for the display can be summarized as follows:
1. Power terminates to the display using a 120 VAC power cord that plugs
into the recessed panel on the back of the display.
2. Incoming power goes through an electrical line filter and a fuse. It is then
distributed to the transformer and the power supplies mounted to the back
sheet of the display.
3. The controller board receives about 10 VAC from the transformer.
4. The power supplies are set to 5.3 VDC. For assistance with the wiring to
the power supplies see the Schematics. Power supplies are preset. Contact
Daktronics Customer Service for the proper settings.

Accessing and Replacing the Controller Board
The display controller is mounted to the back sheet of the cabinet in the lower left corner.
The controller receives, interprets, and activates the information from the computer to the
appropriate LEDs on the display.
The controller board includes three LEDs:
1. DS1 should be on whenever power is applied to the board.
2. DS2 should have a steady flash to indicate that the controller is running properly.
The normal rate is about once per second. The run LED will flash faster when the
controller is in test mode.
3. DS3should flash when receiving information from the light sensor.
4. See
Figure 34 below for LED and connector locations.

To replace a failed controller:
1. Disconnect power to the display.
2. Open the display and lift the LED module panel to access the interior
components.
3. Label all the signal cables before removing them from the controller
4. Remove all power and signal connections from the board. Pressing outward
on the tabs, and carefully pulling them from the jack releases the “Locked”
connectors.
5. Remove the #6 mounting screws. Five of the five screws are hex head,
while one is a Philips head. Remove the mounting six screws using a 3/16"
nutdriver.
6. Take note of the switch configuration and set the same address on the new
controller.
7. Carefully remove the controller board from the display.
8. Attached the new controller using the #6 screws. Be sure to replace the
Philips head screw in the location where it was removed.
9. Reconnect the power and signal cables.
Display Addressing
Before a display can be run in a sign network, it must have an
address. The display address can be set using “DIP” switches
located on a PC board known as the MDC. The MDC is the circuit
card mounted on the left end of the controller board.
Locate the DIP switches on the MDC. They should be on the
bottom end of the card. Refer to
switches.
When replacing a controller board, be sure to set the DIP switches
to the same address configuration as the defective controller. The
DIP switches follow standard binary code.
Note: By setting the DIP switches to address 0 (flip all the switches
up or toward the numbers on the circuit board), a test mode can be
activated. The display’s power must be turn off and then back on to
recognize test mode, or any address change.

1.2 RS422 Loop-Back Test (Indoor/Outdoor Displays)
All indoor displays and some outdoor displays (AE-3010, AF-3010, AF-3020, and
X-1000) use RJ11 plugs or connectors. In those cases, a “Network Cable Tester”
Figure 7) is provided to conduct the test.
(
The Network cable tester is used to test for two things:
1. That a flipped RJ11 cable is beingused.
2. That there is good connection from a computer or signal converter.
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 5: Flipped Cable (Reversed)
Figure 6: Straight Cable
1. Plug one end of the flipped cable into the output from the computer or
signal converter.
2. Plug one end of the
flipped cable into J2
(Loopback
Connector) on the
Network cable tester
box.
3. When both ends are
connected, perform
the loop-back test
using the Venus 1500 software as described in Section 1.4..

5. When the fibers are connected, perform
the loop-back test using the Venus 1500
software as described in Section 1.4.
6. For AF-3010 and X-1000 displays only,
the cable that connects the fiberboard to the controller board input uses a
RJ11 jack at the controller and can be connected to a loop-back box at J2 to
run the test as usual.

3. Right click the network you want to test.
Signal Converters and Loop-Back
Testing for Direct Connections
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 retrieve the status to ensure
communication now works correctly.

Appendix C: Optional Temperature
Sensor
The optional temperature sensor can be
mounted outside, but it requires a location
away from the influence of chimneys, air
conditioners, vents, tar roofs, concrete, and
parking lots that can cause abnormal
temperature fluctuations. Usually, a separation
of at least 20 to 30 feet horizontally and eight
feet vertically is required to achieve this.
Locations where air movement is restricted are
also unsatisfactory.
The recommended location for the temperature
sensor 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 added shading,
usually obtained on a northern exposure. There
should be at least one foot between the bottom
of the eave and the top of the temperature
sensor housing for accurate readings, as seen in
Figure 36 .
Due to the nature of the signal cable used to send th e temperature information, the maximum
distance between the temperature sensor and the display is 1,000 feet (304.8 meters).
A 4-conductor cable with
shield is used to connect
the temperature sensor to
the display. The cable is
terminated in the green
Phoenix plug in recessed
signal termination jack on
the back of the display.
