Daktronics BA-1518 Multi-Section Outdoor LED Scoreboard - Manual (Page 40)

34 Scoreboard Troubleshooting
5.10 Trumpet Horns
For scoreboards that include clocks and have trumpet horns installed, refer to the Trumpet
Horn Installation Manual ED-10006, available online at
www.daktronics.com/manuals.
5.11 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.
5.12 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/electronic captions, radio receivers, and trumpet
horns. Use the following tables to determine the driver schematics for a particular model:
