Component Locations & Access
All internal electronic components and digits are reached by opening a digit panel on
the front of the display.
Digit panels are typically held in place on the
display face by screws. To remove a digit,
simply unfasten the screws and carefully lift it
from the cabinet. The power/signal plug can
then be removed from the connector on the
back of the digit to completely free the digit
and access internal components.
Component location varies with each model, but drivers and power and signal
components are typically mounted inside the cabinet behind a digit panel. To locate
the driver(s), look for a warning label similar to that shown in Figure 4.
Replacing Digits
LEDs are embedded in a circuit board that is
mounted to the back of the digit panel. Do not
attempt to remove individual LEDs. In the case of
a malfunctioning LED or digit segment, replace the
entire digit circuit board. The process of replacing
digits varies by whether it is a PanaView digit or
UniView digit (Figure 5).

Replacing a Driver
1� Open the digit panel nearest the driver as described in Component Locations &
Access (p� 5).
2� Disconnect all plugs from the driver by squeezing the locking tabs together and
pulling the connectors free. It may be helpful to label the cables or take a picture to
know which plug goes to which jack when connecting the replacement driver.
3� Remove the nuts securing the driver to the driver tray.
4� Carefully lift the driver from the display and place it on a clean, at surface.
5� Position a new driver over the screws and tighten the nuts.
6� Reconnect all plugs to their mating jacks on the 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� 9).
8� Close and secure the access panel, and then power up and test the display to verify
the issue has been resolved.

Setting the Driver Address
Reference Drawings:
Address Table, 1 Through 128............................................................................ DWG-115078
Address Table; Rotary Switches H and L ........................................................ DWG-1198765
Power and Address Details; Indoor Tennis Scoreboards.............................. DWG-3019367
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 10) using a small athead screwdriver.
Refer to the tables below or an older driver being
replaced to determine the correct address setting.
Then see DWG-1198765 in Appendix C for addressing
information of driver addresses 1 – 255.
• For older 16-column and 4-column drivers, addresses are
set with jumper wires in a 12-pin plug which mates with
jack J19 on the driver (Figure 11). It may be possible to
reuse the same address plug from the driver that was
replaced. If not, rst refer to the tables below or an older
driver being replaced to determine the correct address
setting. Then see DWG-115078 in Appendix C for a listing of
the wire/pin connections for driver addresses 1 – 128.
Note: If an older 16-column driver needs replacement, it will
be replaced by a new 16-column “Gyrus” driver. If it’s
not possible to reuse the same address plug, refer to
the tables below to determine the correct address
setting. Then see DWG-1198765 in Appendix C for
addressing information of driver addresses 1 – 255.

Multiple Drivers
Displays that require multiple drivers operate using a primary/secondary driver
conguration. The two drivers have been designed to simply plug into one another, and
this is done at the factory, so no additional on-site connection is necessary.
If it appears as though only a certain group of digits on the scoreboard is not functioning,
there may be a problem with the secondary driver(s) or the power/signal connection
from the other driver(s).
Note: The BB-2117 and BB-2119 require an interconnect cable connected to the driver
in the BB-2116. Refer to appropriate schematics listed in Appendix B.

Radio Connections
To determine the radio connection settings between the display and control console,
rst power off any radio-equipped consoles in the area, then cycle power to the display,
and watch for the radio settings. These settings appear in different locations based on
the scoreboard layout:
• When using an All Sport console, the RC-200
hand-held controller, or the DAK Score mobile
app, the display will show “bX CY” where X
is the Broadcast group number and Y is the
Channel number. The default is b1C1.
• If there is a clock, the settings appear in the
rst four clock digits (Figure 12).
• If there is no clock, the settings should
appear in the Home and Guest score digits,
but this may vary by scoreboard model.
• When using the RC-100 hand-held controller,
the display will show “CXX”, where the XX is a
channel from 01-15 (Figure 12). The default is
channel 01.
If these settings do not appear, the radio receiver
may need to be repaired/replaced.
To make sure the console radio settings match the receiver in the display, refer to the
appropriate control console manual..
Radio Interference
If it has been determined that a nearby display’s radio signal is interfering, the settings of
the radio receiver or wireless base station inside the display(s) must be changed.
1� To locate the radio receiver or base station, simply look for the black antenna sticking
out the front of the display. Component Location drawings also show the exact
position where the radio receiver will be mounted.
2� Open the access panel to which the receiver is attached as described in
Component Locations & Access (p� 5).
The channel selection process varies depending on whether the display is equipped with
or a radio receiver (All Sport 5000) or a wireless base station (RC-100/RC-200).

Display Overview
Team Name Message Centers (TNMCs) are programmable LED displays that can show
custom Home and Guest names or messages of about 15 characters in place of static
vinyl captions. TNMCs are typically factory-installed, but they can also be added later,
after the scoreboard has been mounted. Characters are shown on one line using single-
or double-stroke fonts 6" (152 mm) or 8" (203 mm) high.
Electronic captions, on the other hand, are pre-programmed to only show specic labels
to match the captions for a particular sport mode, making it much simpler to switch
between sports. Characters are shown on one line using single-stroke fonts.
TNMCs and electronic captions (Figure 16) are both available with red, amber, or white
LEDs. Refer to the table below for additional message center specications.

Initialization Information at Startup
Each time the display is powered up and there is no All Sport signal present, the display
runs through an initialization process during which it tests all LEDs and addresses. The
message center rst displays the proper address number.
If the entire display fails at startup, power may not be properly connected or the address
setting may not be correct on the display driver. Check both in the event of a failure.
