Mechanical Installation 5
Section 3: Mechanical Installation
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.
3.1 Cart Assembly
Reference Drawings:
Mechanical Specifications, MS-2013.................................................................... A-159886
Cart Assembly....................................................................................................... A-159889
The display cart (Figure 4) comes standard with two
wheels, but may use four if ordered. Cart assembly
requires the following pieces of hardware:
T-stands @ 2
Axle tubes @ 4
10" wheels @ 2 (or 4)
5/8"-11 x 4" bolts @ 2 (or 4)
5/8" flat washers @ 8 (or 16)
5/16" diameter pins with clips @ 6
A 15/16" wrench is needed to attach the wheels.
Refer to Drawing A-159889 in Appendix A and the
following instructions to assemble the cart:
1. Insert the axle tubes into the T-stands, and secure them with pins and 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 with pins and retaining clips.
(The tubes mounted on either side of the scoreboard are permanent attachments; do
not remove them during cart disassembly.)
3. Mount the first wheel to one end of the T-stand, using washers as spacers, and secure
the wheel with an axle bolt. Add flat washers as needed until the wheel is snug but
still rolls freely. Repeat the process for the second wheel; tighten the bolts with a
15/16" wrench.
Note: Two more optional wheels may be installed on the opposite T-stand.
3.2 Adjusting the Cart
Drawing A-159886 in Appendix A shows the two axle positions that may be used with the
cart. The extended axle position provides maximum stability and is recommended for any
situation in which the scoreboard is raised. Use the narrow axle position (and lowest height)
to move the scoreboard through doorways and for storage. The drawing also illustrates front
profiles of the scoreboard in transport position and at maximum viewing height.
There are three height-adjustment holes in the support tubes on the sides of the scoreboard.
Raise the scoreboard for viewing by removing the pins and retaining clips, sliding the
scoreboard upward on the T-stands and reinserting the pins in the appropriate holes.
Figure 4: Cart Assembly, Side View

6 Mechanical Installation
Lower the scoreboard for storage or transportation. It may be helpful to have one person lift
the scoreboard while another person adjusts the locking pins.
Caution! Do not raise the scoreboard in high winds or transport the scoreboard in the raised
position. These actions increase the likelihood of tipping over and damaging the scoreboard.
3.3 Optional Equipment Installation
Reference Drawings:

Ad Panel Installation, MS-2013..............................................................................A-160057
Cover Installation- MS-2013..................................................................................A-160060
Caption Kits
The MS-2013 is shipped as a generic multisport scoreboard with a standard clock/score
caption arrangement. The face of the scoreboard displays game time, home and guest scoring,
and period. Four optional caption kits give the scoreboard added versatility:
Custom Team Names
Baseball/Softball Mode
Segment Timing Mode
Volleyball Mode
The aluminum caption panels are applied to the scoreboard face with hook-and-loop fastener
strips. They can be easily removed and replaced for various events, leaving the hook strips
attached to the face of the scoreboard. Refer to Drawing A-159890 in Appendix A for an
illustration of the various caption configurations.
Ad Panel
A custom advertising/school logo panel may be added to the MS-2013. Threaded inserts in
the top of the scoreboard cabinet allow attachment using only three screws. The 12" H x 52"
W (305 mm, 1.32 m) aluminum panel runs the full width of the scoreboard. Drawing A-
160057 in Appendix A illustrates the ad panel installation.
Scoreboard Cover
The aluminum cover protects the MS-2013 during transportation and storage. Flanges on the
cover fit into slots on either side of the scoreboards, and the cover simply slides into place
using handles on the front. Drawing A-160060 in Appendix A illustrates the cover installation.
Note: If a radio antenna is installed on the face of the scoreboard it is highly recommended
to remove the antenna before installing or removing the cover. Refer to Section 4.3 for
more information about radio installations.

Electrical Operation 7
Section 4: Electrical Operation
The MS-2013 can be powered by two different electrical systems: a standard 120 VAC power source
and/or enclosed lead-acid batteries.
4.1 Power & Signal Access
Power and control connections for the MS-2013 are located in a
compartment on the rear of the scoreboard (Figure 5).
To open the rear compartment, turn the adjustable latch a quarter-
turn to the left. To close, shut the access door and turn the latch to
the right. If the latch will not engage because it is too tight, make
several turns to the left, and then turn back to the right to latch
and tighten.
The compartment is also designed for storage of the control
equipment. The compartment door can be closed with the power
and signal cords extending through the slot below the door.
Note: If the scoreboard came with a 100' (30.5 m) signal cable,
there will be two hooks on the rear of the scoreboard which
the cable may be wrapped around for storage.
4.2 Power
Reference Drawings:
Schematic: MS-2013-11........................................................................................ A-158030
Electrical Specifications, MS-2013........................................................................ A-159887
Battery Service, MS-2013 ..................................................................................... A-159891
Power for the scoreboard 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 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 POWER IN 120V AC
receptacle, located in the rear compartment on the back panel of the scoreboard (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 system runs on
battery power.
The MS-2013 is shipped ready for use. The battery charger is factory-mounted in the
scoreboard, and all internal wiring is in place and connected to the driver and batteries.
Figure 5: Control Panel

8 Electrical Operation
The ON/OFF control switch (Figure 5) activates power to the internal scoreboard
components, as well as to the radio receiver or control console.
Turn the switch to ON for scoreboard operation.
At all other times, keep the switch in the OFF position.
Whether or not the scoreboard is operational, its batteries will continue to discharge any time
the switch is in the ON position. Leaving the switch ON when the unit is not in use could
completely discharge and damage the batteries.
Refer to Drawing A-159887 in Appendix A for component locations and illustrations of
internal and external wiring. Drawing B-158030 provides a detailed wiring schematic of
internal scoreboard components for advanced troubleshooting.
Daktronics recommends that the scoreboard remains 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.
4.3 Signal
Reference Drawings:
System Riser Diagrams- MS-2013-11...................................................................A-160237
The MS-2013 can receive control signal three different ways, described below. Refer also to
Drawing A-160237 in Appendix A for diagrams of each of these control setups.
Setup 1 (Standard): A wireless RC-100 handheld controller communicates with a
radio base station installed inside the scoreboard.
Setup 2 (Optional): A 4-pin cable connects the scoreboard directly to the All Sport.
The cable transmits signal output to the scoreboard and power input to the controller.
Setup 3 (Optional): 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.
Connecting Signal Cable
If the scoreboard was ordered with a wired control console, simply plug the signal cable into
the jack labeled CONTROL CONSOLE CONNECT (Figure 5) Attach the mating plug to the
modified power cord from the All Sport controller. Extension cables are also available from
Daktronics if more than the 100' (30.5 m) of control cable provided is needed.

System Riser Diagram: RC-100- MS-2013........................................................... A-244926
Installation Drawing; Outdoor Scbd Gen VI Radio Receiver............................... A-1109181
The RC-100 base station and All Sport radio receiver are typically held in place with
adhesive-backed, hook-and-loop fastener strips, and when ordered as original equipment
may already be installed. The only installation required is attachment of the radio antenna,
which may have been shipped separately to prevent damage.
If the base station or receiver is not already installed:
1. Access the inside of the scoreboard by removing the three (3) screws securing the rear
access panel and swinging it open.
2. Position the unit inside the scoreboard so the antenna connector can extend through
the hole in the upper-right corner on the front of the scoreboard.
3. Remove the backing from the fastener strips on the unit.
4. Insert the antenna jack through the hole, and then firmly press the unit against the
interior front panel, sticking the fastener's adhesive to the sheet metal.
5. Route and connect the cable protruding from the bottom of the unit to the mating 6-
pin jack directly on the LED driver.
Note: For models built prior to April 2015, the radio cable will connect to the 5-pin
jack labeled “J45”coming from the LED driver.
6. Close and secure the rear access panel.
7. From the front face of the scoreboard, note that the antenna connector now protrudes
through the panel.
a. Install and tighten the lock washer and nut on the antenna connector.
b. Mount the external antenna on the connector, turning the nut on the antenna
until it is snug.
c. Rotate the antenna so that it is pointing straight upward (it should look like a
capital “L” when viewed from the side).
Setting the Base Station Function
The base station is preset to Function 2 or 5, Channel 1. If the default settings do not appear to
work, refer to Drawings A-236394 and A-244926 for instruction on changing these settings.
For more information, refer to the RC-100 manual listed in Section 1.1.
Setting the Radio Receiver Channel
The radio receiver is preset to Channel 1. If there are other scoreboards in the facility
operating with radio signal, each scoreboard receiver must be set to a different channel
number (typically starting with 1 and numbering consecutively). Refer to Drawing A-1109181.
Refer to the Gen VI Radio Installation Manual (DD2362277) for more information.
This manual is available online at www.daktronics.com/manuals.

10 Electrical Operation
4.4 Power-On Self-Test (POST)
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. Figure 6shows an
example of the LED bar test pattern that each digit performs.
Radio Settings
With an RC-100 base station installed, the channel settings (“C 01”) will be displayed in the
clock digits (Figure 7) during the POST. If an All Sport radio receiver is installed, both the
broadcast setting (“b1”) and the channel setting (“C1”) will be displayed. These values must
match the settings in the controller (refer to appropriate manual in Section 1.1).

Battery Care & Charging 11
Section 5: Battery Care & Charging
This section describes care and operation of the MS-2013 on-board battery charging system.
5.1 On-Board Charger
Reference Drawing:
Electrical Specifications. MS-2013........................................................................ A-159887
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 scoreboard during the off-season; storing the
scoreboard with a discharged battery can contribute to early battery failure. Daktronics
recommends keeping the scoreboard 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 scoreboards and to extend battery life in applications where scoreboard
and batteries are stored for long periods of time. The charger is located in the cabinet interior,
attached to the left side of the scoreboard back sheet (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 Drawing A-159887 in Appendix A.
Note: Displays built before August 2015 were shipped with the ChargePro model 2607,
which varies from the details provided below. For more information, visit
www.marinco.com/en/2607a.

12 Battery Care & Charging
The ChargePro 28210 charger, shown in Figure 8, is a 2 bank,
10 A, 12/24 VDC output charger with an input of 120 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 indefinitely 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.
The charge cycle is as follows:
A) Soft Start –Charger verifies 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.
B) 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.
C) 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 switch to the next stage.
D) Float Stage –the charger finishes 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.
E) 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 scoreboard's power cord into a standard 120 VAC,
60 Hz outlet. Red and green LED indicators on the charger, visible through holes on the
exterior back panel, indicate the recharging status. A label at this location also describes
charging levels.
Note: When the batteries are connected, they will continuously supply power to the
driver, even if the digits are blank. Make sure that the unit is switched ON only during
an event or when testing. At all other times, the switch should be in the OFF position.
Figure 8: ChargePro Charger

Battery Care & Charging 13
The table below describes how the charger indicators operate:
Scoreboard
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.
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.
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.
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”.
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 scoreboard cabinet.
