Segmentation and Digit Designation
Reference Drawing:
Segmentation, 7 Segment Bar Digit ........................................................ Drawing A-38532
Shop Drawings ................................................................................... Refer to Appendix A
In each digit, certain LEDs always go on and off together. These groupings of LEDs are
referred to as “segments.” Drawing A-38532 illustrates digit segmentation. It also details
which connector pin is wired to each digit segment and the wiring color code used
throughout the display.
The Shop Drawings identify the driver connectors controlling the digits. The number
displayed in the hexagons in the upper half of each digit, indicate which connector is wired
to that digit.
