Light Strip Driver Tray Components
The light strip output terminal block determines when the light strips will illuminate. By
default, end-of-period light strips are triggered when the game clock equals 0, and clock
stopped light strips are triggered when the clock equals stopped. Either type of light
strip may instead be set to illuminate when the shot clock horn or the game clock horn
sounds. Move the gray wire to the appropriate terminal for the desired function.
When troubleshooting 4-column driver problems, two diagnostic LED indicators labeled
DS1
and
DS2
provide the following driver status information:
