Daktronics displays are built for long life, and require little maintenance. However,
from time to time, certain display components will need replacing. The
Replacement Parts List in Section 4.11 provides the names and part number of
components that may need to be ordered during the life of the display. Most display
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 in Section 4.12. Refer to these instructions if any display
component needs replacement or repair.
1.1 Safety Precautions
Important Safeguards:
1. Read an d understand these instructions before installing.
2. Be sure the display and enclosures are properly grounded
with an earth ground electrode at the display.
3. Disconn ect power when servicing the display.
4. Do not modify the display structure or attach any panels or
coverings to the display without the written consent of
Daktronics.
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. Daktronics display systems have been
designed to meet those needs.

Introduction
The common thread to most client requests is a means of programming and
ntrolling a group of displays from a central control point. Daktronics responded by
co
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
adio. Up to 240 displays can exist on one network.
r
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. Most 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 at the computer uses to communicate to the modem in the display. Each
modem network needs to have a dedicated phone line assigned to it. Refer to Section
3 for additional information.
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 computer’s
RS232 signal to fiber optic signal; a minimum of two fibers are required.
Radio Network
The Radio network is a standard communication method that uses radio waves at
high frequencies to transmit signal. The Venus 1500 Radio network has a maximum
distance of 450 meter (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 M anual ,
ED13932, for additional information.

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 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

6. Quick Connect Jack:
The display uses quick connect jacks for the
connection of the temperature sensor, the client radio,
and connection of the primary to the secondary or
mirror display. The quick connect jacks are located
on the back of the display and when not used the
attached cover should be kept closed.

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 at the base of the sign structure.
This cable has a maximum length of 25 feet (7.6 meters).
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:
• In 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 two-
ot separation is required. The maximum length of an RS422 signal cable is 4,000
fo
feet (1.22 km).
Modem
The modem option will use standard telephone cable routed in conduit. Do not run
power and phone cable 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 maximum length of a fiber optic cable is 2,000 feet (611.6 meters).
Radio
The Server radio, connected to the computer through a J-box, requires an 18-gauge
six-conductor cable (Daktronics part number W-1370). Four conductors will be used
for the signal and two for power. This wire needs to be in conduit when exposed to
outdoor conditions out 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
s not need to be in conduit. Note: Secure excess cable to the structure to prevent
doe
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 8pin RJ45.
a typical RJ11 connector. These connectors
can be found on many telephones and
LANs.
The cables used in the display are straight
through cables, meaning that the wire to
pin one on one end is the same as pin one
on 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
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 15 on the right illustrates
Figure 16 below that the color code on one connector must be made the
Figure 15: 6-Conductor RJ11 Connector and Cable

Figure 16: Flipped Cable with RJ Connectors
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 17
on the right.
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 a 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 Drawing B-178625 and Drawing
B-178626 for your display size located in Appendix A for approximate locations for
power 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 Drawing B-178625 or B-178626 for your display.
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 quick connect interconnect cable, the separate signal and temperature
sensor wires can be routed through the same conduit.
3.5 Preparing for Power/Signal Connection
Reference Drawings:
Component Layout Diagrams..................................Refer to Appendix A
1. Punch or use ½ " (0.875) conduit holes for the desired conduit openings. Be
careful that none of the internal components are damaged. Attach the
conduit.
2. Remove the bottom left two
modules (AX01 and AX02) to
expose the power enclosure and
signal panel. Use a
wrench to turn the latch access
fasteners one-quarter 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.
3. Locate th e controller and power
termination box for these
displays in the Component
Layout Diagram.
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 ungrounded 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.

Electrical Installation
Figure 19: Display Grounding
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:
rInstallation with Ground and Neutral Conducto s Provided
For this type of installation, refer to Figure 20. 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
disconnected. The National Electrical Code requires the use of a lockable power
disconnect within sight of or at the sign.
Figure 20: Installation with Ground and Neutral Conductor 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.
Refer to

3. Conn ect the white neutral wire to neutral bus.
4. If one power line is being terminated (120VAC), connect the black “hot”
wire to L1. Install jumper per Drawi ng A-127361.
5. If two power lines are being terminated (120/240VAC). Connect the second
“hot” wire to L2 and remove the jumper.
6. Connect the green grounding wire to the grounding bus E41. Refer to

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 direct line of sight from the display or
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.
3.7 Signal Termination from Computer to Display
Figure 22: Signal Termination at Display (Front View)
The AF-3160 is designed for quicker connection to other displays and other
additional equipment. Connection of the first display to the control equipmen t needs
to be wired to the controller, modem, fiberboard, or surge suppression card in that
display. Depending on the display type ordered the following cables may be
provided with the display:
1. Interconnect cable from Primary to Secondary, length 4 feet
2. Interconnect cable from Primary to Mirror, length 6 feet.
3. Temperature sensor with quick connect cable, length 25 feet
4. Client radio with quick connect cable, length 25 feet
