2.6 LED Drivers
The LED drivers perform the task of switching digits on and off within the scoreboard.
LED drivers are located inside of a driver enclosure. Refer to Figure 10 to view the location
and components of a driver enclosure.
Most scoreboard models use 16-column drivers (Figure 11), while smaller models use 8-
column drivers. Several scoreboard models also contain more than one driver to accommodate
all of the digits and indicators. Refer to the component location drawings in Appendix A to
determine the type and number of drivers for a particular scoreboard model. Also refer to
Appendix B to locate the appropriate schematic drawings.
