Mechanical installation consists of lifting and permanently mounting the scoreboard. The mechanical
specifications Drawing A-133616 in Appendix A shows the recommended number and spacing of
wall anchors for specific scoreboard models.
Be sure that the installation complies with local building codes.
Note: Daktronics does not assume any liability for any installation derived from the information
provided in this manual or installations designed and installed by others.
Daktronics LED squash scoreboards are shipped equipped with ¼" eyebolts along the top of
the cabinet for lifting the displays, as well as pre-drilled holes along the cabinet frame for
wall attachment.
Daktronics strongly recommends using a spreader bar, or lifting bar, to lift the display.
Spreader bars ensure the force on the eyebolts remains straight up, minimizing lifting stress.
Figure 4 illustrates the preferred scoreboard lifting method on the left and an acceptable
alternative lifting method on the right. When lifting the display:
Use a spreader bar if possible.
Use every lifting point provided.
Cables and chains attached to the eyebolts and directly to a center lifting point, as shown in
the right-hand example in Figure 4, can create a dangerous lateral force on the eyebolts and
may cause the eyebolts to fail. The smaller the angle between the cable and the top of the
display, the lighter the sign must be to safely lift it. If this method must be used, ensure a
minimum angle between the chain and scoreboard of at least 45 degrees.
Do NOT attempt to lift the display if the angle is less than 45 degrees.
Figure 4: Lifting Methods

Exceeding load angles or weight limits could cause the
bolts in the scoreboard cabinet to buckle, resulting in
serious damage to the scoreboard or injury to personnel.
Also, loads should be applied directly in the plane of the
eyebolt as shown in Figure 5.
Note: Daktronics assumes no liability for damages
resulting from incorrect setup or lifting methods.
Eyebolts are used to suspend the scoreboard while it
is being installed and may be used, with additional
hardware in a permanent, suspended installation.
1. Use the eyebolts at the top of the scoreboard frame to lift the display into position for
mounting.
2. Secure the display to the wall by attaching mounting hardware through all holes on the
side rear flanges of the display to a pre-drilled hole in the wall (Figure 6).
Due to the variety of wall materials used in sports facilities, Daktronics cannot anticipate a
user‟s individual installation needs or provide mounting hardware suitable for every
installation. Choose a method of installation that will safely support the weight of the display.
Daktronics makes optional protective devices, including screens and netting, to help prevent
damage to the scoreboard due to normal ball impacts.
Note: Some users install devices to protect the scoreboard from projectiles. Scoreboard
protection devices not provided by Daktronics must be approved by Daktronics prior to
installation. Failure to follow this approval procedure will void the scoreboard warranty.

Figure 6: Wall Mounting

CAUTION: Only qualified individuals should terminate power and signal cable and access the
electrical components of the display and its associated equipment. It is the responsibility of the
electrical contractor to ensure that all electrical work meets or exceeds local and national codes.
Daktronics engineering staff must approve all changes or the warranty will be void.
Each scoreboard features a 120 V AC power cord with a three-prong plug. Install a grounded
receptacle near the equipment so that the power cord can easily reach it. The control console
requires a 120 V AC receptacle and uses less than 1 A of power.
Displays operating on 230 V AC are also available, and they are shipped equipped with a
universal power plug.
Connect the scoreboard to earth ground. Proper grounding assures reliable equipment
operation and protects the equipment against damaging electrical disturbances and lightning.
Daktronics recommends a resistance-to-ground of 10 ohms or less. The electrical contractor
performing the electrical installation can verify ground resistance. Daktronics Sales and
Service personnel can also provide this service. The grounding connection on the power
cord‟s three-prong plug connects to the shell of the scoreboard.
Note: The customer must properly ground the outlet according to local and national
codes. Failure to ground the outlet voids the warranty for the scoreboard.
The scoreboard performs a self-test each time that power is turned on and the control console
is powered off or not attached to the scoreboard. If the control console is attached and
powered on, the self-test does not run, and data from the control console is displayed on the
scoreboard after a brief period of time. Each scoreboard self-test pattern will vary depending
on the scoreboard model, the number of drivers and types of digits.
If a radio receiver is installed, the radio broadcast settings (“b1”) and the channel settings
(“c1”) will be displayed in the Home and Guest digits during the POST. These values must
match the settings in the All Sport control console (refer to the appropriate control console
manual listed in Section 1.4).

Electrical Installation
Signal installation requires routing control cable from the scoreboard control console to a
signal junction box (J-box) near the display. Refer to Drawing A-133369 in Appendix A for
more information about signal wire connections.
1. At a minimum, use a paired, 22 AWG shielded cable (Daktronics part number W-
1077) and connect the cable to a J-box at the control console end.
2. Route the cable from the J-box on the control console end to a J-box near the display.
3. Install the ¼ inch phone plug (Daktronics part number 0L-40683) to the scoreboard
end of the cable. Be sure to connect the cable shielding only in the J-box on this end.
4. Insert the plug into the Signal In (J31) jack located on the side of the scoreboard.
5. Connect a signal cable from the J-box to the J1 or J2 jack on the All Sport 1600 console.
6. Plug in and power on the control console and enter the appropriate sport code to test
the scoreboard.

IMPORTANT NOTES:
1. Always disconnect power before doing any repair work on the scoreboard.
2. Permit only qualified service personnel to access internal display electronics.
3. Disconnect power when not using the scoreboard.

All Daktronics LED squash scoreboards are front-access scoreboards, meaning that internal
electronic components and digits are reached by opening a face panel on the front of the
display.
To remove a face panel, simply unfasten the screws holding it in place and carefully lift it
from the cabinet. The power/signal plugs can then be removed from the connectors on the
back of the digits to completely free the digits and access internal components.
Refer to the electrical and signal specifications Drawing A-133613 in Appendix A for exact
component layouts and access locations.
LEDs are embedded in a circuit board that is mounted to the back of the face panel. Do not
attempt to remove individual LEDs. In the case of a malfunctioning LED or digit segment,
replace the entire digit circuit board.
To replace a digit circuit board (Figure 7):
1. Open the face panel as described in Section 5.2.
2. Disconnect the power/signal connector from the back of the digit by squeezing
together the locking tabs and pulling the connector free.
3. Use a 9/32" nut driver to remove the nuts securing the digits to the inside of the panel,
and then lift the digit off the stud inserts.
4. Position a new digit over the studs (making sure the small plastic spacers are still in
place) and tighten the nuts.
5. Reconnect the power/signal connector.
Note: This is a keyed connector and it will attach in one way only. Do not attempt to
force the connection.

Scoreboard Troubleshooting
6. Secure the face panel to the display with the screws, then power up and test the
display to see if changing the digit has resolved the problem.
In each scoreboard, one or more LED drivers perform the task of switching LEDs on and off.
LED drivers are located inside of a driver enclosure. Refer to Figure 8 to view the
components of a driver enclosure.
Figure 7: PanaView Digit Assembly
Figure 8: Driver Enclosure Components

The scoreboards in this manual use 16-column drivers. Each driver has numerous connectors
providing power and signal inputs and outputs to the scoreboard digits and indicators.
The table below shows the function of these connectors for a 16-column driver:

Figure 9: Driver Status Indicators

Scoreboard Troubleshooting
If the driver status indicators do not appear to be working correctly, it may be necessary to
replace the driver.
1. Open the face panel as described in Section 5.2.
2. Disconnect all connectors from the driver by squeezing together the locking tabs and
pulling the connectors free.
Note: It may be helpful to label the cables to know which cable goes to which
connector when reattaching the driver.
3. Remove the wing nuts securing the driver to the driver tray.
4. Carefully lift the driver from the display and place it on a clean, flat surface.
5. Position a new driver over the screws and tighten the nuts.
6. Reconnect all power/signal connectors.
Note: The connectors are keyed and will attach in one way only. Do not attempt to
force the connections.
7. Ensure the driver is set to the correct address (refer to Setting the Driver Address).
8. Close and secure the face panel, then power up and test the scoreboard to see if
changing the driver has resolved the problem.
Since the same LED drivers can be used for many
scoreboard models, each driver must be set to
receive the correct signal input, or address, for the
model being used. This address is set with jumper
wires in a 12-pin plug which mates with jack J19 on
the driver (Figure 10).
When setting the driver address, first refer to the
specifications table in Section 2 to find the correct
driver address(es) for a particular scoreboard
model. Then refer to Drawing A-115078 in
Appendix Afor a listing of the wire/pin connections
for driver addresses 1 –128.
In each digit, certain LEDs always go on and off together. These groupings of LEDs are called
segments. Drawing A-38532 in Appendix A details which connector pin is wired to each
digit segment and the wiring color code used throughout the display.
The component location drawings in Appendix A also specify the driver connectors
controlling the digits. Numbers shown in hexagons in the upper half of each digit indicate
which connector is wired to that digit.
