Scoreboard Troubleshooting 11

Note: All scoreboards in this manual should be set to address “97”.

Segmentation and Digit Designation

In each digit, certain LEDs always go on and off together. These groupings of LEDs are called

segments. Drawing A-038532 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 specification drawings in Appendix A 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.

Schematics

For advanced display troubleshooting and repair, it may be necessary to consult the

schematic drawings. Located in Appendix A, schematic drawings show detailed power and

signal wiring diagrams of internal display components.
