4.6 Shot Clock Signal Connection
For permanent shot/game clock installations ( Figure 12 ), signal wiring may be routed from a
J-box at the control console end and terminated at another J-box by the display, similar to the
method used for scoreboards and stat displays. See also
Drawings A-124688 and A-125415 in
Appendix E .

5. Insert the plug into the Signal In (J31) jack located on the side of the shot clock.
6. Repeat steps 1-5 for the other shot clock.

If using an optional Shot Clock Start/Stop Switch (Daktronics part # 0A-1196-0031),
