Component Location & Access
To access the driver, digits, or other internal components, remove the screws securing the
face panel(s) to the scoreboard. Some panels are hinged at the bottom and will swing
downward.
Replacing Digits
LEDs are embedded in a printed circuit board (PCB) 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:
1. Open the face panel as described in Component Location & Access (p.7).
2. Disconnect the plug 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 spacers and standoff studs.
4. Position a new digit over the studs. Make sure the small plastic spacers are still in
place, and then tighten the nuts.
5. Reconnect the plug to the back of the digit. This is a keyed connector and will attach
in one way only. Do not force the connection.
6. Close and secure the face panel, then power up and test the display to verify the
issue has been resolved.
LED Drivers
The LED driver performs the task of switching digits on and off within the display. Refer to
the electrical and signal specications drawings in Appendix A to determine the location
of the driver in a particular scoreboard model.
When troubleshooting driver problems, several LEDs shown in Figure 4 provide diagnostic
information. The number of LEDs and their function depends on the driver type.
Note: While it is necessary to have the display powered on to check the LED status
indicators, always disconnect power before servicing.

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 it is being
used. The way the address is set depends on the driver
type:
• For 16-column “Gyrus” drivers, addresses are set
through the S2 (L) and S3 (H) rotary switches on the
driver (Figure 5) using a small athead screwdriver.
Model Driver #

WR-2101
WR-2102
WR-2103
Driver located in WR-2101,
WR-2102, or WR-2103
• For older 16-column drivers, addresses are set with jumper
wires in a 12-pin plug which mates with jack J19 on the
driver (Figure 6).
Note: If an older 16-column driver needs replacement, it will be replaced by a new
16-column “Gyrus” driver. It may be possible to simply reuse the same address
plug from the driver that was replaced. If not, refer to the table above to
determine the correct rotary switch address settings for the new driver.
Segmentation & Digit Designation
Reference Drawings:
Segmentation, 7 Segment Bar Digit ................................................................... DWG-38532
In each digit, certain LEDs always go on and off together. These groupings of LEDs are
referred to as segments. DWG-38532 in Appendix A details which connector pin is wired
to each digit segment and the wiring color code used throughout the display.
The electrical and signal specication 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.

Horns
Matside Jr. scoreboards are equipped with a 120 VAC vibrating horn mounted behind
the lower-front panel. The horn sounds automatically when the period clock counts
down to zero, or when manually triggered by the operator using the control console.
Adjusting Horn Volume
CAUTION: The horn is a 120 VAC device. Turn off the power before adjusting the horn.
The volume for the electronic, buzzer-type horn is set at its maximum level at the factory.
If the horn is too loud, reduce its volume by adjusting the setscrew mounted in the front of
the horn. A plastic tip on the screw touches the horn’s diaphragm, reducing the volume.
Turn the screw clockwise and test the volume by operating the horn from the scoreboard
control console. Continue adjusting and testing until the desired volume level is obtained.
Note that with spectator noise, the horn will not seem as loud as when it is being tested in
an empty area, so be sure to set the volume according to the acoustics of the facility.
