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 complexity
of multiple display installations has emerged, and Daktronics display systems have
been designed to meet those needs.
The common thread to most client requests is a means of programming and
co
ntrolling a group of displays from a central control point. Daktronics responded by
developing a powerful system of interconnecting and controlling displays. 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 display or group of displays in the network which
message should run
• The ability to determine the status of any display on the network
• The ability to control multiple display technologies on the same network
There are five (5) network systems available: RS232, RS422, modem, fiber, and
r
adio. Up to 240 displays can exist on one network.
RS232 Network
RS232 (EIA/TIA-232-E) is a standard communication interface that employs a
single-ended serial transmission scheme that uses a maximum cable length of 7.6
meters (approximately 25 feet). This interface was designed for computer
communication at short distances. All computers have an RS232 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 that uses a typical maximum cable length
of 1.2 km (approximately 4000 feet). The main advantage to RS422 over RS232 is
the longer cable length that is possible. 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 controller and display. Each modem network
needs to have a dedicated phone line assigned to it. Refer to Section 3 for additional
information.
Introduction
1-3
Fiber Optic Network
A fiber optic network is a standard communication method transmitting light (signal)
through a glass fiber. Fiber optic cable has a maximum length of 600 meters
(approximately 2,000 feet). A signal converter is needed to convert the computers
RS232 signal to fiber optic signal; a minimum of two fibers is required. Refer to
Section 3 to additional information.
Radio Network
The Radio network is a standard communication method that uses radio waves at
high frequencies to transmit signal. The Venus
distance of 450 meters (approximately 1500 feet) outdoor and 150 meters
(approximately 500 feet) indoor. A nearly straight line-of-sight path must be
maintained between the Server Radio connected to the computer and the Client
Radio connected to the display. Refer to Section 3 and the Venus 1500 Radio
manual, ED-13932, for the additional information.

1.4 Component Identification
The following illustrations depict some of the more commonly accessed Galaxy®
display components. Because Daktronics occasionally alters standard design to meet
customer needs, the actual display design may vary slightly from the illustrations
below.
This is only a brief overview. Refer to Section 4 for additional information on
maintaining the various display components.
Com Port: A COM port is a connector on the back of the control computer. The
COM port is used to control the display network through either a 9- or a 25-pin serial
connector.
Controller: The display’s controller is the “brains” of the display (refer to Figure 2
below). The controller receives signal information from the control computer,
translates it, and activates the appropriate pixels on the display accordingly.

The method used to mount displays can vary greatly from location to location. For
this reason, only general mounting topics can be addressed in this manual.
It is the responsibility of the installer to ensure the installation will adequately
meet local codes and standards. The mounting hardware and method is also the
responsibility of the installer.
Before beginning the installation proces s, verify the following items:
• The mounting structure will provide a straight and square-mounting frame
for the display. Height variation in any fou r -f oo t hori z ontal section may
not exceed ¼-inch.
• The mounting structure will not give way at any unsupported points after
the display is mounted.
The back of the display is equipped with 2 x 2 x ¼" steel clip angles at the locations
shown in Drawings B-172745 and B-172746. These angles may be used for
mounting purposes. Remember to have all mounted displays inspected by a qualified
structural engineer. It is the customer’s responsibility to determine the proper wall
mounting method and location.
Refer to Drawings B-172745 and B-172746 for a suggested wall mount method. The
number of attachment points needed and the wall structure must be reviewed by a

Mechanical Installation
Eyebolts
Almost every display that leav es D ak tronics is equipped w ith ey ebolts for lifting the display . There are
two standard sizes of eyebolts: ½″ and A″.
Load Increase Factor: The load increases as the lift angle (θ) decreases. The allowable load on the
eyebolts also decreases with the lift angle due the bending stress on the eyebolts. In sum, the smaller
the angle between the cable and the top of the display, the lighter the sign must be to safely lift it. Do
NOT attempt to lift the display when the lift angle is less than 30 degrees.

A. Do not use eyebolts on angular lifts unless absolutely necessary. For angular lifts, the shoulder pattern
eyebolt is preferred.
B. Load should always be applied to eyebolts in the plane of the eye, not at some angle to this plane.
C. Shoulder eyebolts must be properly seated (should bear firmly against the mating part), otherwise the
working loads must be reduced to those indicated for regular eyebolts. A washer or spacer may be
required to put the plane of the eye in the direction of the load when the shoulder is seated.
D. No load greater than the safe working load listed in the data table should be used.
E. To obtain the greatest strength from the eyebolt, it must fit reasonably tight in its mounting hole to prevent
accidental unscrewing due to twist of cable.
F. Eyebolts should never be painted or otherwise coated when used for lifting. Such coatings may cover
potential flaws in the eyebolt.
G. To attain the safe working loads listed for regular eyebolts, 90% of the thread length must be engaged.

3: Section Electrical Installation
Only a qualified individual should terminate power and signal cable within this
Daktronics display.
The Daktronics engineering staff must approve any changes made to the display. Before
altering the display, submit detailed drawings for the proposed modifications to the
Daktronics engineering staff for evaluation and approval or the warranty will be rendered null
and void.
3.1 Common Connectors in the Display
The power and signal connections in the displays use many 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 connector.
The following information presents some common connectors
encountered during display installation and maintenance.
1. Ribbon Cable Connectors:
Figure 9 illustrates a typical ribbon connector. To disconnect the
ribbon cable, push the plastic clips on the sides of the jack to
unlock and remove the cable.
Before replacing a ribbon cable connector, spray it with DeoxIT
contact cleaner to remove any foreign matter that may cause
signal problems. In addition, apply a generous amount of
CaiLube
™
protector paste to the plug before 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
display from an external source. Power wires need to have onehalf 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
Figure 10.

3. Phoenix
™
-Style Connectors:
Phoenix-style connectors, which are usually green, are often used for
signal termination on circuit boards. Refer to
Figure 11. Strip one-
quarter inch of insulation from the wire prior to termination. To
remove a wire, turn the above screw counter-clockwise to loose the
connectors 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 displays are white and come
in a variety of sizes.
Figure 12 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):
RJ connectors, as seen in
Figure 13, are similar to the telephone connectors
found in homes and are used on the ends of flat RJ11 cable. 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
™
contact cleaner to
remove any foreign matter that may cause signal problems. In addition,
apply a generous amount of CaiLube
™
protector paste to the plug before
inserting it into the jack. This paste will protect both the plug and the jack
from corrosion.
6. Six-Pin Insulation Displacement Connector
The six-pin connectors found in the display are keyed connectors, meaning
that they will only go together one way and should not be forced. To
remove the connector squeeze the plastic tab and gently pull the plug from
the jack.

3.2 Control Cable Requirements
RS232
This cable is a 2-conductor shielded cable used to transmit an RS232 signal
(Daktronics part number W-1117). This shielded cable should not be subjected
to mechanical flexing after installation. This cable is not for direct burial and
should be routed in a dedicated, grounded metallic conduit from the base of the
sign structure. Power and signal cable cannot be run in the same conduit. This
cable has a maximum length of 25 feet (7.6 meters).

Connector
Electrical Installation
RS422
This cable is a 4-conductor shielded cable used to transmit an RS422 signal
(Daktronics part number W-1234). This shielded cable consists of paired wires. They
should not be subjected to mechanical flexing after installation. This cable is not for
direct burial and should have one of the following routings:
• Dedicated metallic conduit – power and signal cable cannot be run in the
same conduit
• Inside buildings − if cable is not in conduit, keep away from interference
signals
With interference signals (such as power conductors, intercom, etc.) typically a twofo
ot separation is required. The maximum length of an RS422 signal cable is 4,000
feet (1.22 km).
Modem
The modem option will use standard telephone cable routed through conduit. Power
and phone cable cannot be run in the same conduit. The local telephone company
will need to assist in this installation. Ask the telephone company which color is used
for the TIP wire and which color for the RING wire for signal hook up.
Note: T
board/communications system.
he telephone lines must be dedicated lines and not run through a switch
Fiber Optic
This cable is a 4-fiber cable (Daktronics part number W-1376). Two fibers are used
for display communications and the other two are saved for spares. The cable may be
either direct burial or routed in conduit but it should not be subjected to mechanical
flexing. The fiber can be routed in the same conduit as the power. The maximum
length of a fiber optic cable is 2,000 feet (611.6 meters).
Radio
The Server radio connected to the computer requires an 18-gauge six-conductor
cable (Daktronics part number W-1370). Four conductors will be used for the signal
and a two for the power. These wires need to be in co nduit when exposed to outdoor
conditions to the Server radio. The maximum distance from the J-box to the Server
radio is 1000 feet (305.8 meters).
The Client radio at the display comes with cable that is rated for outdoor use and
doe
s not need to be in conduit. Note: Secure excess cable to prevent it from being
pulled loose by weather or vandalism.

3.3 RJ Connector Cables
Two types of RJ connectors are used in
the display. There is the 6-pin RJ11 and
the 8-pin RJ45.
typical RJ11 connector. These
connectors can be found on many
telephones and LANs.
The cable used in the display are straight
through cables meaning that the wire to
pin one at one end is the same as pin one
at the other end, and so forth. When
installing a network, and on cables
exterior to the display, flipped cables are
often used. This cable has one end that is
the mirror image of the other end (i.e. the
cable is flipped). Refer to
standard flipped cable.
Notice in
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 14 illustrates a

Electrical Installation
Installing an RJ Connector
Installing an RJ connector on the end of the conductor cable is a
simple task when the correct tools are used. The RJ 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 16.
The crimping tool is then used to crimp the RJ connector onto the cable. The RJ
connector is locked into a special socket in the tool. The stripped wire is inserted into
the RJ connector. Finally, the tool is squeezed like pliers to crimp the connector onto
the wire. This completes the installation of an RJ connector onto the wire.

Daktronics does not include the conduit. Refer to Drawings B-172745 and B172746 for your display size for approximate locations for pow er and signal conduit.
Separate conduit must be used to route:
• Power
• Signal IN wires, including phone line
• Signal OUT wires (if signal is required for another display)
Knockout holes for ½" conduit are located at the bottom right (rear view) of th e back
of the display (refer to Drawings B-172745 and B-172746).
For displays with more than one face, signal and temperature sensor wiring between
displays is normally completed using the quick connect interconnect cable. If not
using the interconnect cable, the separate signal and temperature sensor cables can be
routed through the same conduit.

2. Remove the bottom left two modules (AX01
and AX02) to expose the power enclosure
and signal panel. To do this, use a
wrench to turn the latch access fasteners onequarter turn. Turn the top latch clockwise and
the bottom latch counter-clockwise. Lift each
module away from the display; reach behind
it and disconnect all power and signal
connections. Refer to Figure 17
3. Locate the controller and power termination
box for these displays in the Component
Layout Diagram for your sign
4. The controller receives the incoming signal
and relays it to the individual modules
5. Route power to the display through a fused
disconnect switch capable of opening all ungr o un ded power conductors.
Install this disconnect within the line of sight of any personnel performing
maintenance on the display. If the disconnect is located out of sight of the
display, it must be capable of being locked in the open position
6. Power conductors from the disconnect to the display should be routed
through conduit in agreement with local code
7. You may route the signal cable from the control computer to the display at
this time – Be sure to run the power and signal cables in separate
conduit

Figure 18: Grounding
A minimum of one grounding electrode must be installed for each display face. The
grounding electrode is typically one grounding rod for each display face. Other
grounding electrodes as described in Article 250 of the National Electric Code may
be used. Daktronics requires that the resistance to ground be 10 ohms or less. If the
resistance to ground in higher than 10 ohms it will be necessary to install additional
grounding electrodes to reduce the resistance. The grounding electrode should be
installed within 25 feet of the base of the display. The grounding electrode must be
connected to the ground terminal in the display panel board.
Power Installation
There are two considerations for 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:
3-8
Electrical Installation
Installation with Ground and Neutral Conductors Provided
For this type of installation, the power cable 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 opened. Refer to
Figure 19 for installation details. The National Electrical Code requires the use of a
lockable power disconnect within sight of or at the sign.
Figure 19: Installation with Ground and Neutral Conductors Provided
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, the followi n g guidelines must be observed:
• Connect the grounding electrode cable at the local disconnect, never at the
sign panel board.
• A disconnect that opens all of the ungrounded phase conductors should be
used.
• The neutral and the ground conductors should be bonded in the sign panel
board.

Main Disconnect
The National Electrical Code requires the use of a lockable power disconnect near
the display. Provide a lockable disconnect switch (knife switch) at the display
location so that all power lines can be completely disconnected. Use a 3-conductor
disconnect so that both hot lines and the neutral can all be disconnected. The main
disconnect should be mounted at or near the point of power supply connection to the
display. A main disconnect is to be provided for each supply circuit to the display.
The disconnecting means must be located in a di
outline lighting that it controls. This requirement provides protection by enabling a
worker to keep the disconnecting means within view while working on the display.
Exception:
Disconnecting means that are capable of being locked in the open
position may be located elsewhere.
