Introduction

1.3 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
have been 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

All the programming features would seem insignificant if the systems could not be
accomplished with basic tools and without technical difficulty. Daktronics decided to
use the very popular and readily available RJ11 connector. This connector is also
used on modern home and office telephone equipment.

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 fiber
optic.

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 8
meters (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, 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 that is possible. A signal converter is needed to
convert the computer’s RS232 to RS422. Refer to Section 3 for additional
information.

Introduction

1-3

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.

Fiber Optic Network

A fiber optic network is a standard communication method transmitting light (signal)
through a glass fibe r. Fiber optic cable has a maximum length of 2 ,000 feet. A signal
conductor is needed to convert the computer’s RS232 to fiber optic signal. Refer to
Section 3 for additional information.

Radio Network

The radio network is a standar d communication method tha t uses radio waves at high
frequencies to transmit signal. The Venus 1500 Radio network has a maximum
distance of 1,500 feet outdoor and 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 radio manual
(ED-13932) for additional information.

1.4 Display Overview

Reference Drawing:

Shop Drawing...........................................................Refer to Appendix C

The Daktronics outdoor 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. They can become
double-faced by mounting them back-to-back with a second unit.

1.5 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 below.

This is only a brief overview. Refer to Section 4 for more detailed information on
maintaining and troubleshooting various sign components.

Com Port: Connector on the back of the control computer. The COM port is used to
control the sign network through either a 9- or a 25-p i n serial connector. The
computer requires a serial port to work with this display.

Controller: “Brains” of the sign. The controller receives, translates, and activates the
signal information from the control computer to the appropriate pixels on the sign
accordingly.

Figure 2: MDC Controller

Driver/Pixel Board: Responsible for the switching and intensity levels of the LEDs.
The LED pixels are mounted directly onto the pixel board. The driver is located on
the back of the display board.

Network: Consists of multiple signs connected to each other. Up to 240 Venus 1500
controlled displays can exist on one network.

Pixel: Cluster of four LEDs. The number and color of the LEDs depends on sign
application.

Power Supply: Converts AC line voltage from the load center to low DC voltage for
one or more module driver boards.

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).

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

Introduction

address to locate and communicate with each sign, but signs on the same network
cannot have the same address.

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 straight though serial cable.

1.6 Daktronics Nomenclature

Figure 6: Module Numbering Example – 24x160 Front

To fully understa nd some Daktronics drawings, such
as schematics, it is necessary to know how various
components are labeled in those drawings. This
information is also useful when trying to
communicate maintenance or troubleshooting
efforts.

A module is the building block of the Galaxy sign.
Each module measures 8 pixels high by 16 pixels
wide. By placing modules side-by-side and on top of
one another, a sign of any size can be designed and
built. Individual modules can be easily removed

Figure 7: Module Numbering

from the sign if required. Figure 6 above illustrates
how Daktronics numbers modules on a Galaxy sign.
Figure 7 on the right breaks down the module
numbering method.

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.

Introduction

1-7

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 a re commonly found on dr awings. Those part
numbers can be used when requesting replacement parts from Daktronics Customer
Service. T ake 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 4.13, use the label to order a replacement.
A typical label is shown in Figure 8 on the right. The part
number is in bold.

Introduction

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.

Section 2: Mechanical Installation

Note: Daktronics does not guarantee the warranty in situations where the sign is not consta ntly
in a stable environment.

Daktronics engi neering staff must approve any changes that may affect the weather-tightness
of the sign. If any 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 installations 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

Support structure design depends on the mounting methods, sign size, and weight.
The structure design is critical and should be done only by a qualified individual.
Sign height and wind loading are also critical factors. It is the customer’s
responsibility to ensure that the structure and mounting hardware are adequate.

Daktronics is not responsible for the installations or the structural integrity of
support structures done by others.

It is the installer’s responsibility to ensure the mounting structure and
hardware are capable of supporting the sign, and will agree with local codes.

Before beginning the installation process, verify the following.

· The mounting structure will provide a straight and square-mounting frame

for the sign.

· The mounting structure is capable of supporting the sign and will not yield

at any unsupported points after mounting.

Correct any deficiencies before installation.

Mechanical Installation 2-1

2.3 Display Ventilation Requirements

Reference Drawing:

Shop Drawing...........................................................Refer to Appendix C

Fans are mounted inside the back of the display for cooling. Fresh air inlets and
exhaust vents should not be obstructed in any way (refer to shop drawings located in
Appendix C). Using the Daktronics suggested mounting methods will ensure proper
ventilation. Fans turn ON when the interior display temperature reaches 140º F.

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.

2.4 Mounting Kit

A mounting kit is available when ordering a display. The mounting kit includes the
hardware to either mount the display on a pole or on a wall. When using a Daktronics
mounting kit, refer to the instructions in Section 2.5.

2.5 Display Lifting

Reference Drawing:

Shop Drawing...........................................................Refer to Appendix C

Eyebolts are provided on the top of each display for lifting purposes. Refer to
ED-7244 at the end of this section for the proper lifting procedure. A spreader bar
should be used to maintain a vertical force on each eyebolt. Using cables or chains to
attach the eyebolts directly to the central lifting point can apply dangerous lateral
force to the eyebolts. Do not use the eyebolts for permanent installation. Refer to
shop drawings for the dimensions of the eyebolts from each end of the display.

Once the display is permanently mounted, replace the eyebolts with the hex-head
bolts (supplied by Daktronics) and sealing washers used with the eyebolts. Use water
proofing compound, such as silicon, along with bolts and sealing washers, to ensure a
waterproof seal.

Section 3: Electrical Installation

Only a qualified individual should terminate power and signa l 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 rendered null and void.

3.1 Common Connectors in the Sign

The power and signal connections i n the signs 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 cable and connector.

The following information presents some common connectors encountered during
sign installation and maintenance:

1. Ribbon Cable Connectors:
Figure 10 on the right 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
may cause signal problems. In addition, apply a generous
amount of CaiLube
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 Figure 11 on
the right.

Electrical Installation 3-1

3. Phoenixä-Style Connectors:

Phoenix-style connectors, which are usually green, are often
used for signal termination on circuit boards. Refer to Figure
12 on the right. 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-Lokä Connectors:

The Mate-n-Lok connectors found in the signs are white and
come in a variety of sizes. Figure 13 on the right illustrates a
four-pin Mat e-n-Lok connector. To remove the plug fo rm the
jack, squeeze the plastic locking clasps on the side of the
plug and pull it from the jack.

Figure 12: Phoenix-

Connector

Style

5. Phone Jacks (RJ11/RJ45 Connectors):

RJ connectors are similar to the telephone connectors found
in homes and are used on the ends of RJ11 or 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
any foreign matter that may cause signal problems. In
addition, apply a generous amount of CaiLube

™

contact cleaner to remove

™

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 Control Cable Categories

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 Figure 14 on the right. This
cable has one end that is the mirror image of the
other end (i.e. the cable is flipped). Refer to
Figure 15 on the following page for a standard
flipped cable.

Figure 13: Mate-n­Lok Connector

Figure 14: 6-Conductor RJ11 Connector and
Cable

3-2

Electrical Installation

Notice below in Figure 15 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.

Daktronics does not include the conduit. Knockouts will be provided for power and
signal. Separat e conduit must be used t o route:

· Power

· Signal IN wires

· Signal OUT wires (if signal is required for another display)

The conduit holes are located at the bottom right (rear view) of the back of the
display (refer to shop drawings located within Appendix C).

To access the knockouts, release the face panel latches using an 8mm Allen wrench
(provided by Daktronics). Open the face panel. Caution: The door will swing up.
Remove the bottom left module (front view) to reach the knockouts (refer to Section

4.3 to remove a module).

Punch or drill out the desired knockouts. Be careful that none of the internal
components are damaged. Attach the conduit and route the power and signal cables.
Refer to Drawing A-88427 for a picture of the power and signal termination panels.

For displays with more than one face, signal and temperature sensor wiring between
displays can be r outed through the same conduit.

Electrical Installation 3-3

3.4 Grounding

Displays must be grounded according to the provisions outlined in Article 250 of the
National Electrical Code

®

. Daktronics recommends a resistance to ground of 10
ohms or less. The electrical contractor who is performing the electrical installation
can perform verification of ground resistance. Daktronics Sales and Service
personnel can also perform this service.

The display system must be connected to e arth-ground. Proper grounding is
necessary for reliable equipment operation. It also protects the equipment from
damaging electri cal disturba nces and lightning. The display must be properly
grounded or the warranty will be void.

The material of an earth-ground electrode differs from region to region and from
conditions present at the site. Consult the National Electrical Code and any local
electrical codes that may apply. The support structure of the display cannot be used
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.

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:

Ins allation w th Ground and Neutral Conductors P ovided t i r

For this type of installation, the power cable must contain an isolated earth-ground
conductor. Under this circumstance, do not connect neut ral 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.
Refer to Figure 16 below for installation details. The National Electrical Code
requires the use of a lockable power disconnect within sight of or at the display.

3-4

Figure 16: Installation with Ground and Neutral Conductors Provided

Electrical Installation

Ins allation w th Only a Neutral Conductor Providedt i

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 following guidelines must be observed:

· Connect the grounding electrode cable at the local disconnect, never at the
display power termination panel.

· A disconnect tha t opens all of the ungrounded phase conductors should be
used.

· The neutral and the ground conductors should be bonded in the display
power termination panel.

Refer to Figure 17 below for installation details.

Figure 17: Installation with Only Neutral Conductor Provided

3.5 Control Cable Requirements

RS232

This cable is a 2-conductor shielded cable used to transmit an RS232 signal
(Daktronics part number W-1117). This unshielded 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 display structure.
This cable has a maximum length of 25 feet.

Electrical Installation 3-5

RS422

This cable is a 6-conductor shielded cable used to transmit an RS422 signal
(Daktronics part number W-1210). This unshielded cable consists of un-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

· Inside buildings - if cable is not in conduit, keep away from interference

signals

With interference signals, such as power conductors, intercom, etc., typically a two­foot separation is required.

Modem

The modem option will use a standard tele phone cable routed through a conduit. The
local telephone company will need to assist in this installation.

Ask the telephone company which colors the TIP uses, and the RING for signal hook
up.

Note: The telephone lines must be dedicated lines and not run through a switch
board/communications system.

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.

3-6

Radio

The Server radio connected to the computer requires an 18-gauge six-c onductor
cable (Daktronics part number W-1370). Four-conductors will be used for the signal
and two for power. These wires need to be in conduit when exposed to outdoor
conditions to the Server radio. The maximum distance from the J-box to the Server
radio is 1,000 feet (305.8 meters).

The Client radio at the display comes with cable that is rated for outdoor use and
does not need to be in conduit. The cable should be secured to the structure so it does
not come loose from the display.

LEDs and Jumpers

The modem module has two (2) LEDs. The Power LED should remain lit while
power is applied to the modem. The Active LED will light when the modem is in the
process of communicating.

A modem system requires jumpers to be set on the controller board. Refer to Section

4.6 for these jumper settings.

Fiber Board

The fiberboard has three LEDs. The power LED
(DS1) should remain lit while power is applied to
the module. The receive LED (DS2) will light
when the display fiberboard is accepting signal
from the fiber signal converter. The transmit LED
(DS3) will light when the display fiberboard is
sending to the fiber signal converter. In addition,
the fiberboard has two input fiber connectors that
the signal converter or the previous display
connects to, and two output fiber connectors that
connect to the next display. The fiberboard
connects to the controller board with a small DB9
to RJ11 adaptor and a straight RJ11 cable.

To replace a fiber optic board: Tools required:

8mm Allen wrench, 5/16" nutdriver, and 3/16"
nutdriver

1. Open the display and remove the module

in front of the fiber board in the lower left corner.

2. Disconnect the power and signal connections (refer to Figure 32 above for

disconnection of power).

3. The fiber optic board is held in place with four 3/16" screws. Carefully

remove them.

4. Install the new fiber board, replace the screws, and reconnect power and

signal cables.

4.10 Structural Inspection

Visual inspectio n should be done annually to check paint a nd look for possible
corrosion, especially at footings, structural tie points, and ground rods. Fasteners
should be checked, tightened, or replaced as required.

At least once a year, check the inside of the display for signs of water intrusion, i.e. ­water stain marks. Water can enter a display where weather stripping has come loose
or deteriorated, where fasteners have come loose allowing gaps in the panels, or
where moisture may be entering around hardware. Check the electronic components
for signs of corrosion.

Check/clean the filters for proper air flow.

4.14 Daktronics Exchange and Repair and Retur n
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 price 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 resto cking 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 Daktronics Help Desk for the RMA#. This will
expedite the receiving process.

4-12

Maintenance and Troubleshooting

Packaging for Return: Package and pad the item well to prevent damage during
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.

Appendix A: Optional Temperature

Sensor

The optional temperature sensor is
mounted separately and requires a location
away from the influence of chimneys, air
conditioners, vents, tar roofs, concrete, and
parking lots that can cause abnormal
temperature fluctuations. Usually, a
separation of at least 20 to 30 feet
horizontally and eight feet vertically is
required to achieve this. Locations where
air movement is restricted are also
unsatisfactory.

The recommended location for the
temperature sensor is a north eave or
northern exposure away from direct
sunlight and above grass. This location
gives extra stability and accuracy to the
sensor because of the added shading,
usually obtained on a northern e xposure.
There should be at least one foot between
the bottom of the eave and the top of the
temperature sensor housing for accurate
readings, as seen in Figure 34 on the right.

Due to the nature of the signal cable used
to send the temperature information, the
maximum distance between the
temperature sensor and the display is 1,000

feet (304.8 meters).

Another recommended location for a
temperature sensor is on the display
itself, or somewhere on the display
structure. A light-colored display is
preferred in this application. Location of
the sensor should be above, below, or on
a northern edge to try to keep the sensor
shaded. If mounting above the display, a
minimum height of six feet is requi red. If
mounting below the display, a minimum
of eight feet above ground and a
minimum of one foot between the sensor
and display are required, as seen Figure
35 on the right. Greater accuracy is
obtained if there is grass below the
display, rather than concrete or some
other material.

Refer to Figure 35 above for wiring instructions.
