5.10 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 A details which connector pin is wired to each
digit segment and the wiring color code used throughout the display.
The component location 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.
5.11 Schematics
For advanced scoreboard troubleshooting and repair, it may be necessary to consult the
schematic drawings. These drawings, located in
Appendix A , show detailed power and
signal wiring diagrams of internal display components such as drivers and transformers as
well as optional components like TNMCs and radio receivers. Use the following table to
determine the driver schematics for a particular model:
