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.

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 trans
e ability to tell a display or group of displays in the network which

• Th

message should run

e ability to determine the status of any display on the network

• Th
e ability to control multiple display technologies on the same network

• Th

Tools required for mounting the display depend on the location and size of the
display. For some installations, it may be possible to use pre-terminated telephone
cables for use with the displays.

There are six network systems available: RS232, RS422, modem, fiber, radio and

hernet. They differ in the type of physical connections needed, the distance

Et
allowed, and the equipment used. A separate manual is provided for the type of
communication method ordered with your display. See Section 3.7 for the
communication manual ED numbers.

Up to 240 displays can exist on one network.

Introduction

Figure 4: Module Numbering Example – 24x64 Front

A module is the building block of the
display. Each module measures 8 pixels
high by 8 pixels wide. By placing modules
side-by-side and on top of one another,
Daktronics can design and build displays
of any size. A person can easily remove
individual modules from the displays if
required.

Figure 4 illustrates how

Daktronics numbers modules on a Galaxy
display.

Figure 5 breaks down the module

numbering method.

In addition, various Daktronics drawings
may contain the following labeling formats:

• “TB_ _” shows a termination block for power or signal cable.

• “F_ _” denotes a fuse.

• “E_ _” signifies a grounding point.

• “J_ _” stands for a power or signal jack.

• “P_ _” represents a power or signal plug for the opposi t e jack.

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:

®

Figure 5: Module Numbering

• “0P-_ _ _ _-_ _ _ _” gives the form of an individual circuit board, such as a

fiber optic board.

• “0A-_ _ _ _-_ _ _ _” represents an assembly, such as a circuit board and the

plate or bracket to which it mounts. A collection of circuit boards working
as a single unit may also carry an assembly label.

• “W-_ _ _ _” indicates a wire or cable. Cables may also carry the assembly

numbering format in certain circumstances. This is especially true of ribbon
cables.

• “F-_ _ _ _” signifies a fuse.

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 8 illustrates a typical ribbon connector. To

disconnect the ribbon cable, push the plastic clips on the
sides to unlock and remove the jack.

Before replacing a ribbon cable connector, spray it with
DeoxIT
may cause signal problems. In addition, apply a generous
amount of CaiLube

™

contact cleaner to remove any foreign matter that

™

protector paste to the plug before
inserting it into the jack. This paste protects both the plug
and the jack from corrosion.

2. Termination Blocks:

Termination blocks connect internal power and signal
wires to wires of the same type coming into the display
from an external source. Most signal wires come with
forked connectors crimped to the ends of the wire. 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 Figure 9.

3. Phoenix™-Style Connectors:

Phoenix-style connectors, usually green, allow for signal
termination on circuit boards. Refer to Figure 10. Strip
one-quarter inch of insulation from the wire prior to
termination. To remove a wire, turn the above

screw counterclockwise to loosen 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. Phone Jacks (RJ11/RJ45 Connectors):

RJ connectors, as shown in Figure 11, are similar to the
telephone connectors found in homes. 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

Figure 11: RJ45
Connector

™

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.

5. Mate-n-Lok

™

Connectors:

The white Mate-n-Lok connectors found in the displays
come in a variety of sizes. Figure 12 illustrates a five-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.

6. Quick Connect Jack:

The display uses quick connect jacks for the connection of

Figure 12: Mate­n-Loc Connector

the signal termination enclosure and the temperature
sensor. There is one quick connect input board with
three input jacks. The board is located on the back of
the display, and when the jacks are not used, the
attached dust cover should be kept closed.

To attach the cable to a jack, make sure to line up the
plug to match the jack, push the plug in, and then turn
the outer collar to lock in place. Figure 13

disconnect is located out of sight of the display, it must be capable of being
locked in the open position.

3. Power conductors from the disconnect to the display should be routed
through conduit in agreement with local code. Run the power and signal

cables in a separate conduit.

4. Display power will terminate to the display at the power termination box

located behind the second module from the left when viewed from the front.

5. Conn ect the grounding electrode conductor to the display at the ground lug.

6. An enclosure is provided with the display for termination of signal. (If the
installation of the display does not allow for the use of the enclosure, the
manual for the communication type shows the alternate termination method
for the signal.)

Refer to Drawings A-192935 and A-192937 for voltage and current requirements for
the display size. The display will use either a 120/240VAC single-phase power or
120/208 three-phase power source.

Do not connect the display to any voltage other than that listed on the
Daktronics product label.

Proper power installation is imperative for proper display operation. The following
sub-sections give details of display power installation.

Grounding

This sign is intended to be installed in accordance with the requirements of
Article 600 of the National Electrical Code and/or other applicable local codes.
This includes proper grounding and bonding of the sign.

Displays must be grounded according to the provisions outlined in Article 250 of the
National Electrical Code
less. Verification of ground resistance can be performed by the electrical contractor
who is performing the electrical installation. Daktronics Sales and Service personnel
can also perform this service.

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. The display must be properly

grounded or the warranty will be void.

A grounding lug is included on the back of the display for easier connection of the
grounding electrode.

®

. Daktronics requires a resistance to ground of 10 ohm s or

Figure 15: Display Grounding

Electrical Installation

3-5

A minimum of one grounding electrode must be installed for each display face. The
grounding elec

trode 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 is 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 on the back of the display.

This grounding electrode must be installed in addition to the equipment-grounding

nductor that should be part of the power installation. The material of an earth-

co
ground electrode differs from region to region because of conditions present at the
site.

The support structure of the display cannot be use

d as an earth ground electrode. The
support is generally embedded in concrete, and if in earth, the steel is either primed
or it corrodes, making it a poor ground. The grounding system and grounding
electrodes must be installed according to Article 250 of the National Electrical Code
and any applicable local codes.

Power Installation

There are two considerations for power installation: installation with ground and
neutral conductors provided and installation with on ly a neutral conductor provided.
For these displays, installation with ground and neutral conductors provided is used.

Electrical installations must be performed by qualified personnel. Unqualified

ersonnel should not attempt to install the electrical equipment. Serious danger to

p
equipment and personnel could occur if equipment is improperly installed.

3-6

Installation with Ground and Neutral Conductors Provided

For this type of installation, the power cable must con

tain 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 display.

Power Connection

Display power is connected to the power termination panel in the display. Complete
the following steps to terminate the hot, neutral, and ground wires to the termination
panel. Refer to Drawing A-192369 for assistance.

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 all power lines can be completely disconnected. Use a disconnect to
disconnect the hot lines and the neutral. Mount the main disconnect at or near the
point of power supply connection to the display. Provide a main disconnect for each
supply circuit to the display.

You must locate the means of disconnection 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 d isplay.

Exception: You may locate the disconnecting means that are capable of being
locked in the open position elsewhere.

3.6 Signal Termination from Computer to Display

The 64mm, AF-3400 Mono display is designed for quicker signal and power
connection to the display and between displays.

• Signal will terminate to a watertight enclosure, which connects to the
primary display using a quick connect cable.

• Mounting the temperature sensor to the display structure and at least one
foot away from the display is preferred – terminate it to the primary display
with a quick connect cable (DO NOT mount the temperature sensor
between displays, or anywhere the airflow is restricted).

• If two primary displays are being used, signal and temperature sensor wires
will be connected between the controllers on each display.

A separate manual is provided for explaining the connection to the signal termination
enclosure. There are seven different methods of communication; your manual will
be one of these types:

4.2 Signal Summary

The signal routing for the display can be summarized as follows:

1. Data from the controller computer, which runs Venus

travels via RS232, RS422, modem, fiber optic cable, radio signal or
Ethernet to the signal termination enclosure at the primary display.

2. From the signal enclosure, signal is sent to the primary display via a quick
connect cable.

Maintenance and Troubleshooting

®

1500 software,

4-1

3. From the quick connect input bo ard, the signal is transferred to the display’s
controller via a 20-conductor ribbon cable.

4. From the controller, the signal then travels over 20-conductor ribbon cables
from the controller (J11 through J18 provides signal out) to J2 on the driver
of the first row of modules in the display.

5. The data ex ists at J1 and is then relayed to J2 of the next driver board and so
on, traveling down the entire row of modules. The drivers use this display
data to control the LEDs.

6. From the first display controller, signal can also be transferred to another
display controller in a second display.

7. Refer to Figure 18

for the signal summary in a primary display.

4.13 Daktronics Exchange and Repair and Return
Programs

To serve customers' repair and maintenance needs, Daktronics offers both an
Exchange Program and a Repair and Return Program.

Daktronics' unique Exchange Program is a quick, economical service for replacing

components in need of repair. If a component fails, Daktronics sends the

key
customer a replacement, and the customer, in turn, sends the failed component to
Daktronics. This not only saves money but also decreases display downtime.

Daktronics provides these plans to ensure users get the most from their Daktronics

roducts, and it offers the service to qualified customers who follow the program

p
guidelines explained below. Please call the Help Desk – 877-605-1113 – if you have
questions regarding the Exchange Program or any other Daktronics service.

When you call the Help Desk, a trained service technician will work with you to

lve the equipment problem. You will work together to diagnose the problem and

so
determine which replacement part to ship. If, after you make the exchange, the
equipment still causes problems, please contact our Help Desk immediately.

If the replacement part fixes the problem, package
and wrapping in which the replacement part arrived, fill out and attach the enclosed
UPS shipping document, and return the part to Daktronics. In most circumstances,
you will be invoiced for the replacement part at the time it is shipped. This bill,
which represents the exchange price, is due when you receive it.

Daktronics expects immediate return of an exchange part if it does not solve the
problem
damaged due to acts of nature or causes other than normal wear and tear.

If you do not ship the defective equipment Daktronics within 30 working days from
the invoice
outright (with no exchange), and you will be invoiced for it. This second invoice
represents the difference between the exchange price and the full purchase price of
the equipment. The balance is due when you receive the second invoice.

. The company also reserves the right to refuse equipment that has been

1.1 Temperature Sensor Overview

The temperature sensor enclosure is made up of eight plastic
disks, a metal mounting bracket, and a 25-foot weather resistant
cable. Refer to Figure 1.

In most cases, the enclosure will be mounted using two screws.
The cable will be plugged into the back of the display.

In certain cases, it may be necessary to disassemble the enclosure
or rewire the temperature sensor board. Instructions are
provided for those situations. If replacement or additional parts
are needed, refer to the following chart for part numbers.

1.2 Mounting Locations

For greater accuracy of temperature, follow these mounting recommendations:

• An ideal location is under a north eave or on a northern exposure away from direct

sunlight (Figure 4).

• Mount the sensor above grass or vegetation rather than concrete or other paving.

• Mount at least 20 feet away from chimneys, vents, air conditioners, or other items that

would influence correct temperature readings.

• Do not mount between displays or in any location that restricts air movement.

• Mount the sensor so that the cable can be protected from weather and vandalism.

The most common locations for the temperature sensor are on the display cabinet (Figure 2),
or on the display structure (Figure 3). A light-colored display is preferred in this location.
Location of the sensor should be below or on a northern edge of the display to keep the
sensor shaded.

When exposed to outdoor conditions, it is necessary to route cable through conduit. In cases
such as this, the quick-connect cable must be extended or replaced with four-conductor, 22­AWG, shielded cable. The maximum length of the cable should be no more than 500 feet.

Mounting to a sheet metal surface

Follow these instructions when mounting the sensor to a sheet metal surface:

1. Drill two pilot holes using a 5/32” drill bit. Horizontally space the holes 1.5” apart.

2. Insert two self-drilling screws through the holes of the mounting bracket, and screw

into the pilot holes.

3. Route cable up to the quick-connect jack on the back of the display and plug into J31.

Refer to Section 1.3 for an example of connection.

1.3 Temperature Signal Connection

Three options for signal connection are explained in this section:

• Using the 25-foot quick-connect cable.

• Using the quick-connect cable but less than 25 feet.

• Using more than 25-feet including extension cables or 22 AWG shielded cable.

Using the provided 25-foot quick-connect cable

1. The temperature sensor is provided with a 25-foot weather-

resistant cable. This cable does not need to be in conduit. The
sensor connects to the display at J31. Refer to Figure 5 for the
location of the quick-connect plug.

2. Secure any excess cable to discourage vandalism.

3. Between displays, the quick-connect signal cable connects

both communication and temperature signal, thus no
additional wiring is required from display to display for the
temperature sensor.

Figure 5: Quick-connect Cable

p. 2 ED-14377-Rev4

p. 3 of 6 Optional Temperature Sensor Mounting

Using the quick-connect cable and less than the 25-foot cable

1. Open the temperature sensor housing by removing the four nuts from the bottom

and then removing the five bottom disks. Refer to Drawing A-198371 for details on
sensor housing disassembly.

2. Disconnect the quick-connect CAN temperature sensor cable from the temperature

terminal block in the CAN temperature sensor housing.

3. Cut the cable to the desired length and reattach to the temperature sensor terminal

block in the CAN temperature sensor housing. Refer to the table and Figure 6 for the
temperature sensor wiring.

4. Make sure to route cable around the sensor board as shown in Figure 7 and Drawing

A-197884.

5. Reconnect the cable and reassemble the sensor.

Using more than 25-feet of cable

To meet customer needs, Daktronics has designed extension cables that allow extra length
from the sensor to the display without separate rewiring. These cables contain the correct
circular ends to be used with the quick-connect cable and quick-connect input. Refer to the
parts list in Section 1.1 for the cable options available.

If 22 AWG shielded cable is used instead of the cable extensions, follow these steps:

1. Run 1/2” conduit from the temperature sensor to a knockout on the back of the

primary display. The cable must be routed through 1/2” metal conduit that should
be earth-grounded to protect the sensor and controller from lightning damage.

2. Use a 2-pair 22 AWG individually shielded cable to connect the sensor to the 8-

position terminal block in the display labeled “CAN US/DS” (A31/TB4). Connect to
the controller as shown in Figure 8.

3. Open the temperature sensor housing by removing the four nuts from the bottom

and then removing the five bottom disks. Refer to Drawing A-198371 for details on
sensor housing disassembly.

4. Disconnect the quick-connect temperature sensor cable from the terminal block in the

temperature sensor housing.

5. Connect the cable coming from the display’s terminal block to the temperature

sensor board in the temperature sensor housing. Refer to Figure 8 and table below
for wiring locations at the sensor and to the controller.

6. Make sure to route cable around the sensor board as shown in Drawing A-197884.

Connect the cable and reassemble the sensor. Refer to Figure 8 and to the table below
for the temperature sensor wiring.

Note: The cable length from the sensor to the display should not exceed 500 feet.

1.4 Temperature Interconnection Between Displays

If the display uses the quick-connect interconnect cable, this connection is already complete.

If the interconnect cable was not used, a 4-conductor shielded cable is needed to terminate
the temperature sensor from side one to side two. One end terminates at the “CAN US/DS”
8-position terminal block (A31-TB4) on the Primary display. The other end terminates at the
“CAN US/DS” 8-position terminal block (A31-TB4) at the second Primary display. Refer to
Figure 9 and the table for correct interconnect locations.
