24 Scoreboard Troubleshooting
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. Addresses are set
through the S1 DIP switch on the driver (
Figure 17 ) using a pen or small, pointed object.
When setting the driver address, 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-284772 in Appendix E for
addressing information for driver addresses 1 – 128.
ColorSmart and 4-column LED drivers also have the
option of setting the address using jumper wires in a
12- or 16 pin plug which mates with jack J19 on the
driver (
Figure 18 ). 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-284771 in
Appendix E for a listing of the wire/pin connections
for driver addresses 1 – 128 for ColorSmart drivers, or
refer to
Drawing A-115078 for 4-column LED drivers.
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 and Drawing A-308053 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. These drawings, located in
Appendix D , 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.
