Refer to Drawing A-32236 for general system configuration.

1. Provide grounded 120 VAC circuits to display and control locations.

2. Route control signal cable in conduit from the control location to the display location. Two

pairs of conductors (22 AWG min.) are required for each display. One-half-inch conduit is
adequate for these wires.

3. If existing cable in good condition is available, four conductors from it may be used. Cable

should run less than 1000 feet from the control location to the display. For greater lengths,
contract Daktronics.

4. Mount the display sections as described below and Drawing A-26861.

5. For dot-digit models, H-2013S and H-2813S, connect display sections together as shown in
Drawing B-28822. These connections are not applicable for dot-digit model H-813S or any

bar-digit model.

6. Make electrical connections as described in Drawing A-31808 and Section 2.2.

2.1 Mounting

Holes for lifting the display and for attaching the display to the wall are provided in the frame
of the display, as shown in Drawing A-26861.

Due to the variety of wall materials used in sports facilities, we can not anticipate your needs
and provide a mounting bolt or anchor suited to your installation. Suitable mounting
hardware may be purchased at your local hardware store. Bolts with expansion or toggle
anchors are available for a variety of wall materials. Be sure that the method you choose is
adequate to safely support the weight of the display.

Use the holes in the end of the frame to lift the display. Secure the display to the wall with the
holes in the back, as shown in Drawing A-26861. Two holes at the bottom of the display are
provided to secure the bottom of the display to the wall in a similar manner.

2.2 Electrical Installation

Electrical installation involves routing of power and control signal wiring through separate
conduit or wire ways. Control signal cable is not provided as part of this system and can be
purchased locally.

Installation 2-1

2.2.1 Power

2.2.2 Signal

Each display is equipped with a 120 VAC, 3-prong plug. Provide two grounded
receptacles and plug it in. Actual maximum display power consumption is as follows:

Model No. Max. Power

------------- --------------­H-813S 300 watts
H-813B 400 watts
H-2013S 700 watts
H-2013B 950 watts
H-2813S 950 watts
H-2813B 1300 watts

The control console requires a grounded 120 VAC receptacle for power. Power
requirement is less than one amp.

Route conduit and cable between display location(s) and the control location. Use
paired cable, minimum 22 AWG, connecting the cable to the junction box at the
control end. Connect the phone plugs provided to the display end of the cable. Insert
plugs into the jacks on the top of the display. Make connections according to the
drawing on the next page, and chart below.

3.1 Lamp Service

The primary service required by Daktronics Hockey Scoring Systems is to replace lamps
periodically. The replacement lamp is type no. 656, 28V, 60 ma, wedge base and the
Daktronics part number is DS-1115. Do not use a higher powered lamp or a lamp rated for
different voltage or damage may result.

Lamp replacement procedure is illustrated in Drawings A-26872 and A-38533.

3.2 Lamp Driver

In each display the task of switching lamps on and off is performed by the Lamp Driver
(Drawing A-37073). Each Lamp Driver has 20 connectors providing power and signal inputs
and outputs to digits and indicators. The function of each of these connectors is as follows:

Connector Function

1 thru 16 Outputs to digits and indicators
17 Control signal input
18 Power for connectors 1 thru 8
19 Power (120V) for driver logic
20 Power for connectors 9 thru 16

Output connectors 1 through 16 each have 9 pins. Pin 7 provides power to the digit or
indicators wired to that connector. The other 8 pins provide switching connections. Drawings
A-28860 and A-39711 show which connector number or connector and pin number, operates
each digit or indicator in each display model.

Maintenance & 3-3
Troubleshooting

3.3 Segmentation

In each digit, certain lamps always go on and off together. These groupings of lamps are
referred to as "segments". Drawings A-26762 and A-38532 show which connector pin
number is wired to each digit segment, and the wiring color code used throughout the display.

3.4 Fuses

The lamp driver in the scoreboard has 17 fuses. There is one fuse to protect each digit circuit.
These fuses are type AGC-10 (refer to Drawing A-37073) and are located next to each digit
output under a single metal cover.

The other fuse, F17, is type AGC-1/2. It is located near the left end of the driver, under the
same cover as F1 through F16. This fuse protects the driver logic circuit and the fan.

Additionally, each display section has one fuse, F401, located behind the access door, to
protect 120 VAC wiring circuits.

Replace fuses only with fuses of the same type and rating.

3.5 Component Location and Access

Drawing A-28823 shows front views of the three dot-digit display models covered here, and
the locations of the various components. Drawing A-39710 shows the same thing for the
three bar-digit display models covered here. The component numbers correspond to the
schematic, Drawing A-28380 (at the end of Appendix A).

Refer to Drawing A-26762 for locations of lamp drivers and other components.

The lamp driver is located behind the indicator panel. Remove the screws securing the bottom
of the panel to gain access.

3.8 Daktronics Exchange/Repair & Return Programs

To serve customer’s repair and maintenance needs, Daktronics offers both an exchange and a
repair and return program. The exchange program reduces down time by providing timely
replacements parts for 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 (1-800 /
843-9879) 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 20 percent restocking fee.

≅To avoid a 20 percent restocking charge, please return the defective equipment within
30 days from the invoice date.

For items that are not part of our exchange program, Daktronics offers a repair and return
program.

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.

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 the symptoms.
