Scoreboard Troubleshooting 27
Setting the Driver Address
Since the same LED drivers can be used for many
scoreboard models, each driver must be set to
receive the correct signal input, or address, for the
model being used. This address is set with jumper
wires in a 12-pin plug which mates with jack J19 on
the driver (Figure 19).
It may be possible to reuse the same address plug
from the driver that was replaced. If not, first refer
to the specifications table in Section 2 to find the
correct driver address(es) for a particular
scoreboard model. Then refer to Drawing A-
115078 in Appendix E for a listing of the wire/pin
connections for driver addresses 1 – 128 or refer to
Drawing A-115078 for 4-column LED drivers.
Multiple Drivers
Scoreboards that require multiple drivers operate using a master/slave driver configuration.
Master and slave drivers function identically, but slave units lack the power/signal
termination blocks. 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 slave driver(s) or the power/signal connection from the
other driver(s).
5.5 Segmentation and Digit Designation
In each digit, certain LEDs always go on and off together. These groupings of LEDs are called
segments. Drawing A-38532 in Appendix E details which connector pin is wired to each digit
segment and the wiring color code used throughout the display.
The electrical and signal specification drawings in Appendix B 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.
5.6 Schematics
For advanced scoreboard troubleshooting and repair, it may be necessary to consult the
schematic drawings. Located in Appendix D, schematic drawings show detailed power and
signal wiring diagrams of internal display components such as drivers, horn interface cards,
and transformers as well as optional components like TNMCs, radio receivers, and end of
period (EOP) lighting.
