Mechanical installation involves assembly of the cart. The
scoreboard itself requires no assembly or permanent installation.
Some assembly is required, however, for certain scoreboard
options. Scan the QR code at right to view a quick cart
assembly video.
Cart Assembly
ReferenceDrawings:
Mechanical Specications, MS-2113 ............................................................. DWG-3270213
Cart Assembly, Portable Display..................................................................... DWG-3274045
The display cart (Figure4) comes standard with four wheels. Cart assembly requires the
following pieces of hardware:
• T-stands @ 2
• Axle tubes @ 4
• 10" wheels @ 4
• 5/8"-11 x 3" bolts @ 4
• 5/8"-11 nuts @ 4
• 5/16" diameter pins with clips @ 6
A 15/16" wrench is needed to attach the
wheels.
Refer to DWG-3274045 in AppendixA and
the following instructions to assemble the
cart:
1� Insert the axle tubes into the T-stands,
and secure them using pins with
retaining clips.
2� Mount the scoreboard by inserting the two T-stands into the larger tube attachments
on the sides of the scoreboard, and secure the stands using pins with retaining clips.
(The tubes mounted on either side of the scoreboard are permanent attachments;
do not remove them during cart disassembly.)
3� Slide a 5/8"-11 x 3" bolt through a wheel, and then screw a 5/8"-11 nut onto the bolt.
Attach the bolt/wheel/nut assembly to an axle tube. Tighten the bolt with a 15/16"
wrench. Repeat this process for the other wheels. The wheels should be snug in place
but still able to freely rotate.
Adjusting the Cart
Caution!Do not raise the display in high winds or transport the display in the raised
position. These actions increase the likelihood of tipping over and causing injury or
damage to the display.
DWG-3270213 in AppendixA shows the two axle positions that may be used with
the cart. The extended axle position provides maximum stability and should be used
whenever the display is raised. Use the narrow axle position (and lowest height) to move
the display through doorways and for storage. The drawing also illustrates front proles of
the display in transport position and at maximum viewing height.

Schematic: MS-2113......................................................................................... DWG-4107359
Power for the display is provided in two ways: via standard 120 VAC line, or by means of
two sealed lead-acid DC batteries. Daktronics supplies two 12 V batteries, rated at 28
ampere hours (A/H), as original equipment. Refer to Section5:BatteryCare&Charging
(p.9) for information on battery care and use of the on-board battery charger.
The provided 8' (2.4 m) 120 VAC power cord plugs directly into the three-prong POWER
IN120VAC receptacle, located on the back panel of the display (Figure5). Any time
120 VAC power is connected, the internal charger operates; however, the system will not
overcharge the batteries. When the power cord is not connected, the display runs on
battery power.
The MS-2113 is shipped ready for use. The battery charger is factory-mounted in the
display, and all internal wiring is in place and connected to the driver and batteries.
The ON/OFF control switch (Figure5) activates power to the internal display components,
as well as to the radio receiver or control console.
• Flip the switch to ON for display operation.
• At all other times, keep the switch in the OFF position.

ElectricalOperation

Whether or not the display is operational, its batteries will continue to discharge any
time the switch is in the ON position. LeavingtheswitchONwhenthedisplayisnotinuse
couldcompletelydischargeanddamagethebatteries.
Refer to DWG-3275249 in AppendixA for component locations and illustrations of internal
and external wiring. DWG-4107359 provides a detailed wiring schematic for advanced
troubleshooting.
Keep the display plugged in to a 120 VAC power source during storage. Battery life
is enhanced by keeping the batteries fully charged. Typically, batteries will be fully
charged in about 12 hours and will give about 14 hours performance on a full charge.
Signal
ReferenceDrawing:
System Riser Diagrams- MS-2113 ..................................................................... DWG-3274967
The MS-2113 can receive control signal four different ways as described below. Refer also
to DWG-3274967 in AppendixA for diagrams of each of these control setups.
• Setup 1: A wireless RC-100/200 handheld controller communicates with a radio base
station installed inside the scoreboard.
• Setup 2: A 4-pin cable connects the scoreboard directly to the All Sport. The cable
transmits signal to the scoreboard and power to the controller.
• Setup 3: A control console equipped with radio transmitter and its own battery pack
or a separate power cord communicates with a radio receiver installed inside the
scoreboard.
• Setup 4: CUSTOMER-SUPPLIED mobile device or tablet with DAK Score app installed
communicates via Bluetooth®wireless technology to the MX-1 Interface Box, which
connects to the scoreboard with a 4-pin cable.
ConnectingSignalCable
If the display was ordered with a wired control console, simply plug the 4-pin signal cable
into the jack labeled CONTROLCONSOLECONNECT (Figure5). Attach the mating plug to
the modied power cord from the All Sport controller. Extension cables are also available

5 BatteryCare&Charging
This section describes care and operation of the on-board battery charging system.
On-Board Charger
ReferenceDrawing:
Electrical Specications- MS-2113 .................................................................. DWG-3275249
On a full charge, the two internal batteries provide enough power for approximately 14
hours of normal operation. Keeping the batteries charged will help extend their life. Be
sure that the batteries are fully charged before storing the display during the off-season;
storing the display with a discharged battery can contribute to early battery failure. Keep
the display plugged in to a 120 VAC receptacle during storage.
The Marinco ChargePro model 28210 on-board battery charger is designed both to
recharge the batteries of the displays and to extend battery life in applications where
display and batteries are stored for long periods of time. The charger is located in the
cabinet interior, attached to the right wall (as viewed with the rear access panel open).
The charger is connected to the transformer, next to the driver enclosure, and to the
batteries. Refer to DWG-3275249 in AppendixA.
ChargerPowerSpecications
Outputs: two individual isolated outputs with a combined rating as follows:
• When bulk charging: 8–10.5 A at 14.3 VDC
• When absorption charging: 3–10 A at 14.3 VDC
• When oat charging: 0–3 A at 13.3 VDC
Maximum recommended battery size:
• For recharging: Up to 120 A/H
Input:
• Rated AC voltage: 100–240 VAC, 50–60 Hz
• Current draw: 2.5 A at full output
The ChargePro 28210 charger (Figure6), is a 2 bank, 10
A, 12/24 VDC output charger with a wide input range
of 100-240 VAC. It is microprocessor controlled and
has a maintenance mode that will keep the batteries
fully charged. The charger is fully automatic and can
be connected to the twin 12 V lead-acid batteries
indenitely without risk of overcharging. The 28 A/H
batteries provided with the display will typically be fully
recharged after about 12 hours.
The ChargePro 28210 charger is a four-stage, “smart”
charger with “Sense Send” technology that senses
the power needs of each battery and sends the
correct charge regardless of Serial or Parallel output
connections. If the batteries have discharged
unequally, the charger will send more power to the
battery that needs it, resulting in faster charging.
Figure 6: ChargePro Charger

BatteryCare&Charging

The charge cycle is as follows:
1� SoftStart – Charger veries connections are good and the battery is capable of
accepting a charge. Batteries with very low voltage (near dead) will be slowly
charged to not harm the battery. When the battery voltage reaches 10 V for 30
seconds, the charger switches to the next stage.
2� BulkStage – the charger uses constant current and charges the battery to 14.3 V.
When the battery holds the voltage of 14.3 V for 30 seconds, the charger switches to
the next stage.
3� AbsorptionStage – the charger uses constant voltage to charge the battery until the
charge current drops just below the rated current for 30 seconds. At this point the
charger will go to the next stage.
4� FloatStage – the charger nishes the charge cycle by keeping the battery at 13.3 V
for a period of time and determines the battery is charged and shuts down.
5� Maintenance – the charger will monitor the battery and if the battery voltage drops
below 12.8 V or if 14 days have passed since the last charge the charge cycle will
start automatically.
Unlike most automotive "trickle" chargers, the unit will not boil off the electrolyte in a lead-
acid battery when left unattended.
To operate the charger, simply plug the display's power cord into a standard 120 VAC,
60 Hz outlet. Red and green LED indicators on the charger, visible through holes on the
left side of the display cabinet, indicate the recharging status. A label on the rear of the
cabinet also describes charging levels.
Note:When the batteries are connected, they will continuously supply power, even
if the digits are blank. Make sure that the display is powered ON only during an
event or when testing. At all other times, the display should be powered OFF.
The table below describes how the charger indicators operate:
LEDIndicators OperatingCondition
SoftStart/BulkCharge
Red ON
Green OFF
Charger is in the “Soft Start” or “Bulk Stage” and the battery is
being charged. If the red LED stays on for more than 24 hours,
refer to the ChargerTroubleshootingTable(p.11).
AbsorptionCharge
Red ON
Green ON
Charger is in the “Absorption Stage” and delivering constant
voltage to the battery. If both LEDs stay on longer than 24 hours,
refer to the ChargerTroubleshootingTable(p.11).
FloatCharge
Red OFF
Green ON
The charger has moved to the “Float Stage” and is topping off
the charge to the battery and keeping the battery ready to
use. The green light indicates your battery is ready to use. If the
green LED stays on and the battery is known to be low, refer to
the ChargerTroubleshootingTable(p.11).
Maintenance
The charger will monitor the battery, and if the battery voltage
drops below 12.8 V for 30 seconds or if 14 days have passed
since the last charge, the charge cycle will start automatically
and will switch back to “Bulk Stage”.

BatteryCare&Charging
11
Operation
If the ChargePro encounters a DC overload (excessive demand), it will reduce its output
voltage to a safe level to prevent damage. If the positive and negative connectors are
touched together, creating a short, the charger will instantly reduce its output voltage
to nearly 0 V. When the overload is removed, the charger automatically resumes normal
operation.
If the in-line 10 A, 32 VDC fuse in either cable blows due to improper connection to a
battery, replace the fuse with an identical 10 A fuse only (Daktronics part # F-1006).
Never replace a blown fuse with a higher-value fuse.
The charger is waterproof, but the AC plug and DC bolt-type connectors should be
kept dry. It is normal for the charger to become warm during operation; consequently, it
should not contact any surface other than the display cabinet.

RadioInterference
The on-board battery charger generates and can radiate radio frequency energy. The
equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to FCC rules, Part 15.
With proper installation, there should be no interference with any radio communications,
either with the display's own receiver or other radio-controlled devices in the
immediate area. However, if it is determined that this device may be the cause of radio
interference, try to correct the interference with one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment to an AC outlet on a circuit different from the receiver.
Battery & Charging Safety
Note:The following lists are general safety instructions when working with lead-acid
batteries. Some of the safety considerations are not applicable to the sealed
batteries provided with the display as those batteries are self-contained and
cannot be opened, and they are safer than automotive batteries that require
servicing. Exercise caution, however, when working with any lead-acid battery.
PersonalSafetyPrecautions
• Someone should be within range of your voice or close enough to come to your aid
when you work near a lead-acid battery.
• Have plenty of fresh water and soap nearby in case battery acid contacts your skin,
clothing, or eyes.
• Wear complete eye protection and clothing protection. Avoid touching your eyes
while working near the battery.
• If battery acid does contact skin or clothing, wash immediately with soap and water.
If you get acid in your eye, immediately ood the eye with running cold water for at
least 10 minutes, and get medical attention immediately.
• NEVER smoke or allow a spark or ame near the battery.

BatteryCare&Charging

• Be extra cautious while servicing the display to reduce the risk of dropping a tool onto
the battery. It might spark or short-circuit the battery or another electrical part, which
could cause an explosion.
• Remove all personal metal items such as rings, watches, and other jewelry when
working with a lead-acid battery. A lead-acid battery can produce a short-circuit
current high enough to weld a ring or similar item to metal, causing severe burns.
• Use the charger for charging LEAD-ACID batteries only. It is not intended to recharge
common dry cell batteries, which may burst and cause injury to people and damage
to property.
• NEVER charge a frozen battery.
DCConnectionPrecautions
1� Check the polarity markings on the battery.
2� Attach the positive ring terminals (red or white wires with fuse) from each cable on
the charger to the positive (+) terminals of the batteries.
3� Attach the negative ring terminals (black wires) from each cable on the charger to
the negative (–) terminals of the batteries.
4� When disconnecting the charger, rst disconnect (unplug) the AC power cord,
then remove the negative ring terminal from the battery's negative (–) terminal, and
remove the positive (+) ring terminals last.

Component Locations & Access
ReferenceDrawing:
Electrical Specications- MS-2113 .................................................................. DWG-3275249
In the MS-2113, the entire back panel is hinged on the right side (as viewed from the
rear). The left-rear side of the display has 3 slotted latches securing the access panel.
To access the internal scoreboard components, use a athead screwdriver to turn all 3
latches 1/2 twist counterclockwise and swing the access panel open. DWG-3275249 in
AppendixA illustrates the back panel open and all of the internal components exposed.
Note:Disconnect power before servicing the display! Also turn power OFF when the
display is not in use. In addition to discharging the batteries, prolonged power-on
may shorten the life of some electronic components.
Replacing Digits
LEDs are embedded in a circuit board that
is mounted to a black polycarbonate tray
and encased in protective gel. This weather-
sealed digit tray is mounted to the back of a
digit panel as shown in Figure7. Multiple digits
may be secured to a single face panel. Do
not attempt to remove individual LEDs; in the
case of a malfunctioning LED or digit segment,
replace the entire digit. To replace a digit:
1� Open the back panel as described in
ComponentLocations&Access(p.16).
2� Disconnect the 9-pin plug from the back
of the digit by squeezing the locking tabs
together while pulling the connector free.
3� Use a 9/32" nut driver to remove the
nuts securing the digit to the inside of
the panel, and then lift the digit off the
standoff studs.
4� Position a new digit over the studs, and tighten the nuts.
5� Reconnect the 9-pin plug. This is a keyed connector and it will attach in one way
only. Do not force the connection.
6� Close and secure the back panel, then power up and test the display to verify the
issue has been resolved.
