Mech/Elec Specs-Light Strip Controller.......................................................... DWG-4662522

DWG-4662008 provides a general overview of what the nal product will look like

attached to a backboard.

Daktronics provides mounting brackets that can adjust to t different sizes and

manufacturers of backboards. DWG-4662021 shows the various mounting bracket

orientations and how to assemble the light strip frame; select the best mounting bracket

orientation for the backboards in use.

DWG-4662022 shows how to install the light strip frame assembly to the backboard.

Note: If there is a 48" amber light strip, refer to DWG-4638145 for installation instructions.

If using a controller box to run the backboard light strips, attach mounting brackets to the

controller box and attach it to the backstop. Refer to DWG-4662522 for mounting details.

Electrical Overview

Reference Drawings:

Electrical Install Details, LED Light Strips............................................................ DWG-191771

Connection Details: LED Light Strip Controller................................................. DWG-191995

Connection Detail, LED Light Strip Controller ................................................ DWG-3285852

Mech/Elec Specs-Light Strip Controller.......................................................... DWG-4662522

The LED backboard lighting typically receives power/signal from one of three places:

• A shot clock equipped with an LED lighting XLR jack

• An LED light strip controller box

• A transparent shot clock controller box with an LED lighting XLR jack

DWG-191771 explains how to connect the light strips together. Use the 30' (9.1 m) jumper

cable provided with the kit to connect the XLR plug protruding from the bottom of the

LED light strip to one of the above sources. If the jumper cable is too long, cut it and

reattach the XLR plug to the end per the instructions in “Detail B” on DWG-3285852.

DWG-191995 illustrates a typical setup using both controller and shot clocks for light strip

power. The mating XLR jacks on the light strip controller are shown in the rear view on

DWG-4662522. For shot clock XLR jack locations, refer to the specic component location

drawings included in the shot clock’s manual.

Backboard Lighting Kit

Installation Overview

1� Unpack the light strip kit, and inspect all equipment for damage. Immediately report

any problems to Daktronics.

2� Assemble the light strip frame on the ground, face side down. The vertical side light

strips will typically have the top and bottom light strips above and below them;

however, the side light strips may be moved outward to straddle the top and bottom

light strips where vertical space is limited. Refer to DWG-4662021.

Note: Do not make the electrical connections between light strips at this time.

3� Loosely attach four mounting brackets to the light strip frame using two screws per

bracket. As illustrated on DWG-4662021, the mounting brackets have four different

orientations that may be used to t the various styles of backboard perimeters.

4� Lift the light strip assembly up against the rear of the backboard. Slide the mounting

brackets out to make contact with the frame of the backboard.

Note: This step can be performed by one person but is made easier with assistance.

5� The steps to secure the frame to the backboard differ depending on the style of

backboard perimeter:

• For Tube perimeter: secure with self-tapping screws.

• For Angle perimeter: mark the holes for drilling, temporarily remove the light strip

frame assembly, and drill 0.203" holes. Lift the light strip frame assembly back

against the rear of the backboard, align the mounting brackets with the holes,

and secure with #10 screws and nuts.

• For Gared backboard: secure using existing holes and hardware.

6� Make the electrical connections between each light strip segment, and secure the

extra wiring out of the way using black zip ties.

7� Make the electrical connection to either a shot clock or a standalone control

enclosure. If there is a separate control enclosure, install it onto the backboard

structure, and then run wiring to the light strip.

• Be sure to mount the driver enclosure in a location that is appropriate for when

the hoop is in either its game or storage position.

• Be sure to leave enough slack in the wiring to allow the hoop to move between

game and storage positions.

8� Test the light strips. By default, the light strips will illuminate when the game time

equals zero.

Visual Horn Indicator Light Strip Kit (High School Only)

Reference Drawings:

Riser Diagram: HS Light Strip Cntlr Installation.................................................. DWG-304654

Daktronics offers a kit (part # 0A-1230-0188) that allows the light strips to run directly from

the scoreboard. This is typically only for high school facilities where there are no shot

clocks and the light strips only need to function as a visual horn indicator (VHI). Refer to

DWG-304654 for installation instructions.

Note: The light strips will only activate when the scoreboard horn sounds. To change

when the light strips activate, a separate control box or shot clock is required.

Maintenance & Troubleshooting

3 Maintenance & Troubleshooting

Disconnect power before doing any repair or maintenance work on the display�

Permit only qualied service personnel to access internal display electronics.

Disconnect power when not using the display�

Troubleshooting Table

The table below lists potential problems with the lighting systems and indicates possible

causes and corrective actions. This list does not include every symptom that may be

encountered, but it does present several of the most common situations that may occur.

If a problem occurs that is not listed or that cannot be resolved using the solutions in

the following table, contact Daktronics using the information provided in Section 4:

Daktronics Exchange and Repair & Return Programs (p�8).

For additional troubleshooting of a shot clock, scoreboard controller, or other system

component, refer to the product manuals located online at www.daktronics.com/

manuals.

Problem Solution/Items to Check

Display does not light at all.

Check all cable connections:

• Power to the light strip controller (or shot clock/scoreboard)

• Signal to the light strip controller (or shot clock/scoreboard)

from the control console

• Signal from the light strip controller (or shot clock/

scoreboard) to the light strip itself

When using an All Sport 5000 or 5500 series controller, ensure

there is an address plug on the light strip control driver. Refer to

LED Driver (p�6).

Replace controller driver. Refer to LED Driver (p�6).

Light strip comes on at wrong

time.

Make sure gray wire from J6 is connected to appropriate

position on terminal block inside controller. Refer to DWG-

4662522.

Individual LED, or section of

LEDs, is not working.

Swap section of light strip with one known to work correctly to

verify it is defective.

Replace defective portion of light strip.

Component Locations & Access

LED end-of-period lighting system components should be located at each backboard.

Light strips are mounted directly to each backboard with #10 hardware and mounting

brackets. The individual parts of the light strips are directly accessible.

The light strip controller will typically be located on the backboard back stop but may

be mounted elsewhere. Power and signal connections are external, and if necessary,

internal components can be accessed by removing the device’s cover.

Maintenance & Troubleshooting

LED Driver

Reference Drawings:

4 Column LED Driver II Specications ............................................................... DWG-123783

Mech/Elec Specs-Light Strip Controller.......................................................... DWG-4662522

Daktronics LED light strip controllers use 4-column LED drivers to switch LEDs on and off.

Refer to DWG-123783 for detailed driver pin out/switch specications.

Replacing a Driver

1� Open the LED light strip controller enclosure by removing the two screws on the

bottom and lifting off the top. Refer to DWG-4662522.

2� Disconnect all connectors from the driver by squeezing together the locking tabs and

pulling the connectors free. It may be helpful to label the cables or take a picture to

know which cable goes to which connector when reattaching the driver.

3� Remove the four #6 screws securing the driver to the inside of the controller

enclosure.

4� Carefully lift the driver from the controller enclosure and place it on a clean, at

surface.

5� Position a new driver inside the controller enclosure and tighten the screws.

6� Reconnect all plugs to their mating jacks on the new driver. The connectors are

keyed and will attach in one way only. Do not force the connections.

7� Ensure the new driver is set to the correct address. This will be the same address of the

old driver being replaced. Refer to Setting the Driver Address (p�6).

8� Close and secure the controller enclosure, then power up and test the light strips to

verify the issue has been resolved.

Setting the Driver Address

Since the same LED drivers can be used for many display

models, each driver must be set to receive the correct signal

input, or address, for the model in which they are used. This

address is set with jumper wires in a 12-pin plug which mates

with jack J19 on the driver (Figure 4).

It may be possible to reuse the same address plug from the

driver that was replaced. If not, contact Daktronics to order

an Address 1 plug (part # 0A-1150-0122) for All Sport 5000

controlled light strips. For All Sport 5500 controlled light strips

(ColorSmart scoreboards), use a fully-loaded address plug

(part # 0A-1150-0064) set to Address 2, meaning all wires

except red should be cut.
