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 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. Most products 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.

Power Supply: Converts AC line voltage from the load center to low DC voltage
for one or more module driver boards.
Galaxy: Daktronics trademarked name for LED monochrome or tri-colored matrix
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.

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.

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

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.

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.

A RS232 system connects the first sign directly to the computer via an adapter. The
adapter has either a DB9 (0A-1115-0042) or a DB25 (0A-1115-0044) connector on
one side, and an RJ11 jack on the other. One end of the RJ11 cable plugs into this
adaptor and the other end to the display. Refer to
for system layout.
