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 sign installations has emerged, and the
Daktronics display systems have been designed to meet those needs. The common thread to most
clients= requests is a means of programming and controlling a group of signs from a central control
point. Daktronics responded by developing a powerful 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 in the network which message it 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

All of the programming features would seem insignificant if the installation of the systems could not be
accomplished with basic tools and without technical difficulty. Daktronics decided to use the very
popular and readily available RJ-11 connector. This connector is also used on modern home and office
telephone equipment.

All that is required for signal insta llation is standard six (6) conductor modular telephone wire. Tools
required for mounting the display depend on the location and size of the display. For some installations,
it may be possible to buy pre-terminated telephone cables for use with the displays.

There are four (4) network systems available: RS232, RS422, modem and TCP/IP.

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 7.62 meters (25 feet). This interface

1-4

Introduction

was designed for computer communication at short distances. All computers have an RS232
communications port. Refer to Drawing A-91388.

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 compute r’s RS232 to RS422. Refer to Drawing A-91387.

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. Refer to Drawing A-91386.

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 serial server via a Local Area Network (LAN). Information
for the individual displays is distributed from the serial server’s RS232 and output. Refer to
Drawing A-93904.

1.4 Display Overview

The Daktronics Indoor LED displays have been designed and manufactured for performance,
reliability, easy maintenance and lo ng life. The displays consist of an array of LED pixels. The
configuration of the LED pixels is dependent on the family of LED displays. The standard character is
seven pixels high by five pixels wide.

A typical system consists of a Windows-based personal computer (PC) running Venus 1500
software and one or more displays. The PC controls one ore more DataTrac displays. The displays are
offered as single-face displays, which are single-sided stand-alone units. They can become double­faced by mounting the m back-to-back with a second unit.

The Venus 1500 is a software package that runs under Windows 3.1x or Windows 95 operating
systems on an IBM-compatible computer. Refer to the Venus 1500 controller manual, ED-12717, for
installation and maintenance of the Venus 1500 editing station.

DataTrac displays are character-based indoor LED displays that are available in monochrome red or
tri -color (red, green and amber) characters. This display family is for 5x7 single -stroke fonts and
graphic fonts. Daktronics offers the DataTrac displays with a 0.7@, 1.2@ or 2.1@ character in various
lengths. The DataTrac model numbers are described as follows: S-X00-LLL-CCC-DD

S

= 100 = Indoor Monochrome Red

200 = Indoor Tri-Color (Red, Green, Amber)
= Number of Lines Tall (4, 8 and 12 are available)
= Number of Characters per Line (18, 24, 30, 36, 42 or 48)

= Character Height (0.7”, 1.2” or 2.1”)

1.6 Daktronics Nomenclature

To fully understand some Daktronics drawings, such as schematics, it is necessary to know how
various components are labeled in those drawings. You will find this information useful when trying to
communicate maintenance or troubleshooting efforts.

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??” denotes a termination block for power or signal cable.

• “F??” denotes a fuse.

• “E??” denotes a grounding point.

• “J??” denotes a power or signal jack.

• “P??” denotes 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. (Not all possible formats are listed here.)

• “0P-????-????” denotes an individual circuit board.

• “0A-????-????” denotes an assembly, such as a circuit board and the plate or bracket to

which it is mounted. A collection of circuit boards wor king as a single unit may also carry an
assembly label.

• “W-????” denotes a wire or cable. Cables may also carry the assembly numbering format in

certain circumstances. This is especially true of ribbon cables.

• “F-????” denotes a fuse.

• “T-????” denotes a transformer

• “PR-?????-?” denotes a specially ordered part.

It is the customer’s responsibility to ensure that the installation will meet local standards. The mounting
hardware must be capable of supporting all components to be mounted. Daktronics is not
responsible for the installations or the structural integrity of support structures done by others.

Daktronics recommends either a wall mount or a hanging mount method. A removable wall mounting
bracket and eyebolts for hanging are included with each display. Have all mounte d displays inspected
by a qualified structural engineer.

Hanging Mount

The DataTrac has two pre-drilled holes in the top of the
display for use in the hanging mounting method. To
hang a display refer to Drawing A-92315 and the
following instructions:

1. Remove the two retaining screws from the top

of the display using a 5/32" Allen wrench (refer
to Figure 3).

Figure 3: Removing Retaining Screws

2. Slide a washer over the threads of each eyebolt.

3. Insert the eyebolts into the pre-drilled holes on the display
(refer to Figure 4).

4. Hand-tighten the eyebolts.

Note: Hanging the display without using th e supplied eyebolts
will negate the warranty. Attaching or hanging anything from the
display will render the warranty null and void.

Wall Mount

The DataTrac has eight (8) or twelve (12) holes on the back of the
display for the attachment of the wall mounting clips. Refer to

Section 3: Electrical Installation

3.1 Common Connectors

This display uses many different types of connectors for power and signal termination. 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 that may be encountered during display
maintenance. Not all of these connectors are found in every display.

1. Phone Jacks (RJ11/RJ45 Connectors):

RJ connectors, as seen in Figure 9, are similar to the telephone connectors found in
homes and are used on the ends of RJ45 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.

2. Mate -n-LokJ Connectors:
The Mate -n-Lok connectors found in this display are white and
come in a variety of sizes. Circuit boards often used 9-pin Mate -n-Lok
connectors while four -pin connectors and two-pin connectors are often used for
power connection. Figure 10 shows a four -pin Mate-n-Lok connector. To
remove the plug form the jack, squeeze the plastics locking clasps of the side of
the plug and pull it from the jack.

3. Ribbon Cable Connectors:
Daktronics uses a variety of ribbon cables and ribbon cable connectors. Figure

Figure 10: Mate-n­Lok Connector

12 and Figure 11 illustrate two of the most commonly used ribbon cable

connectors. To disconnect ribbon cable connector #1,
squeeze the metal locking clips inward and pull the plug
out of the jack. To disconnect ribbon cable connector #2,
pull each of the plastic locking arms outward and remove
the plug.

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.

3.2 Signal

Cables

The conductor connector used in the
network is an industry standard, 6-pin
RJ-11 or an 8-pin RJ-45. 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 Figure 13. This cable has one end that is the mirror image of the other end (i.e. the cable is
flipped). Refer to Figure 14 for a standard flipped cable.

Notice in Figure 14 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 in put 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 13: 6-Conductor RJ-11 Connector, 8-Conductor RJ-45
Connector and Cable

Figure 14: 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

Figure 15: Wire with
Outer Jacket Stripped

15.

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.

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. If the
proper grounding methods are not followed, the warranty will be void. KNote : Displays must be
earth grounded according to local electrical code.

Power Connection B Pluggable Cord Connected Displays

The DataTrac displays are supplied with a eight (8) foot power cor d. The socket-outlet should be
installed near the equipment and be easily accessible. Plug the power cord into the socket as
shown in Figure 16.

The sign-to-sign connections are the same for the
RS232 system, RS422 system, modem system and
TCP/IP. Refer to the riser diagrams listed above.

When wiring a sign to sign network, the cable and
connectors discussed earlier in this section are
used. Pay special attention to the information
regarding flipped cables to help ensure a successful
installation. The best method of wiring the signs
together is to start at the first sign, as it is
designated to begin the network.

Figure 18: Output Signal Cable Connection

1. Plug the cable into the “SIGNAL OUT” output jack of the first sign (refer to Figure 18) and

the other end of the cable into the input jack of the next sign.

2. Continue this procedure throughout the network. When the wiring is complete, the last sign will

have nothing in the output jack.

bottom of the cabinet of the 8 and 12 line displays (the
4 line displays do not contain fans). The fan filters
should be removed and rinsed with water periodically
to clean any dust or debris that may accumulate during
use. If a fan fails, it must be removed and replaced
with a new fan.

To remove a filter for cleaning, first disconnect the
fan’s power supply. The filter lies between the fan and
the finger guard.

Gently remove the finger guard (refer to Figure 38).
The filter will now be easily accessible. Rinse the filter

Figure 38: Removing Fan Finger Guard

with warm water and allow it to dry before replacing it on the fan.

It is not recommended to operate the fan without
the filter or finger guard in place.

The fan can be removed by first taking off the finger
guard and filter. Each fan is held in place with four (4)
#6-32 by 1-1/2" long screws. Use a flat-head
screwdriver to remove the screws and release the fan
from the back sheet. Use the same screws to attach
the new fan. Replace the filter and finger guard.

Light Detector

A light detector is located near the top of the display in the right support flange for 0.7" displays,
and in the bottom left flange for 1.2" and 2.1" displays. The light detector is used to measure light
levels outside the display and, when enabled through the Venus 1500 software, adjusts the
brightness level of the LEDs appropriately.

The light detector is mounted on a support
flange. To replace the light detector, first
remove the #6 screws from the support flange
(refer to Figure 40).

Disconnect the light detector’s wire to the
display controller. The light detector is attached
to the support flange with #4 screws, standoffs
and nuts. Remove the failed light detector from
the support flange.

Fuse

The MDL-7 fuse is located in the left end of the cabinet, near the display
controller (refer to Figure 41).

To replace the fuse, push and turn the fuse cap, insert the new fuse into the
cap and reattach.

4.4 Controller Address and Test Mode

The controller has a set of “DIP” switches on the side of the controller as shown in Figure 35. These
switches set the hardware address. When replacing a controller board, be sure to set the DIP switches
in the same address configuration as the defective controller.

Note: A test mode can be activated by setting the DIP switches to address 0 (turn all the switches to
OFF by flipping them toward the printed switch numbers). The display’s power must be downed, and
then reconnected to run the test mode.

4.7 Daktronics Exchange/Repair & Return Programs

To serve customers’ repair and maintenance needs, Daktronics offers both an exchange and a repair
and return program. The exchange program reduces down time by providing timely replacement of key
components. This service is provided to qualified customers who follow the program guidelines
explained below. It is our pleasure to provide this service to ensure you get the most from your
Daktronics products. Please call our Help Desk (1-877 / 605-1113) if you have any questions regarding
the exchange program or any other Daktronics service.

When you call the Daktronics Help Desk, a trained service technician will work with you to solve the
equipment problem. You will work together to diagnose the problem and determine which exchange
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 the defective part in the same packaging the
replacement part arrived in, fill out and attach the enclosed UPS shipping document and RETURN
THE PART TO DAKTRONICS. (You may use the same box and packing the exchange part was
sent in.) This will speed up the transaction and alleviate confusion when the failed component arrives at
Daktronics. (Daktronics expects immediate return of the exchange part if it does not solve the
problem.) For most equipment, you will be invoiced for the replacement part at the time it is shipped.
This invoice is due when you receive it.

Daktronics reserves the right to refuse equipment that has been damaged due to acts of nature or
causes other than normal wear and tear.

If the defective equipment is not shipped to Daktronics within 30 working days from the invoice
date, it is assumed you are purchasing the replacement part and you will be invoiced for it. This

second invoice represents the difference between the exchange pr ice and the purchase price of the
equipment. This amount is due when you receive the second invoice. If you return the exchange
equipment after 30 working days from invoice date, you will be credited for the amount on the second
invoice minus a restocking fee.

@To avoid a restocking charge, please return the defective equipment within 30 days from
the invoice date.

Daktronics also offers a Repair and Return program for items not subject to exchange.

Where to Send: To return parts for service, contact your local representative prior to shipment to
acquire a Return Material Authorization Number (RMA#). If you have no local representative, call the

Maintenance &
Troubleshooting

4-11

Daktronics Help Desk for the RMA#. This will expedite the receiving process.

Packaging for Return: Package and pad the item well so that it will not be damaged in shipment.
Electronic components such as printed circuit boards should either be installed in an enclosure or should
be put in an anti-static bag before boxing. Please enclose your name, address, phone number and a
clear description of symptoms.
