The light detector is internally mounted and wired at Daktronics. It is located in the
bottom left corner on the front of the display as shown in
Figure 37 (identified as
assembly 0A-1241-4013 (LT) in the Component Layout Diagram). A 4-conductor
cable is terminated at the terminal block on the light sensor and attached to a jack
that plugs into the controller. The cable connects the light detector to the controller at
J9 (refer to Drawing B-177662). When the displays are mounted back-to-back, only
the primary side has a light sensor.
