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.
