The light sensor is internally mounted and wired at Daktronics. It is located in the
bottom left corner on the front of the primary display as shown in
Figure 38
. In the
Component Layout Diagram the sensor is identified as assembly 0A-1241-4013
(LT). The light and temperature sensors are part of the same CAN network and are
addressed accordingly. The light sensor is address 2.
A 4-conductor cable connects the light sensor to the controller. The cable is
terminated at the terminal block on the light sensor and to a jack that plugs into the
controller. When the displays are mounted back-to-back, only the primary side has a
light sensor
