5.5 Segmentation and Digit Designation
Reference Drawing:
Segmentation, 7 Segment Bar Digit .............................. Drawing A-38532
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.
Scoreboard Maintenance 5-5
and Troubleshooting
The component locations drawings in
Section 5.2
specify the driver connectors
controlling the digits. Numbers
displayed in hexagons in the upper half
of each digit, as shown in Figure 9 ,
indicate which connector is wired to that
digit. (The lower number in the square indicates nominal digit size.)

5.6 Lightning Protection
The use of a disconnect near the scoreboard to completely cut all current-carrying
lines significantly protects the circuits against lightning damage. The National
Electrical Code also requires the disconnect. In order for this system to provide
protection, the power
must
be disconnected when the scoreboard is not in use.
The control console should also be disconnected from power and from the signal
junction box when the system is not in use. The same surges that may damage the
scoreboard’s driver can also damage the console’s circuit.
