All displays in the DataTime series use a light
sensor to regulate dimming functions, but time and
temperature models employ a remotely located
sensor to collect and display temperature
information as well. Both temperature and light-
monitoring electronics are located in the sensor
housing.
(Dimming involves decreasing overall display
intensity, both for better display viewing and to
prolong LED life. The brightness level should be
highest during the day to compete with daylight,
and lower at night.)
The Daktronics Controller Area Network (CAN)
Temperature/Light Sensor is pre-installed in a
protective housing, as shown in Figure 4. The
assembly includes the sensor, mounting bracket,
and cabling with a quick-connect plug. Instructions
in the following subsections describe the placement and connection of the device. Review the
wiring diagram and connection illustration in Drawing A-184840 before beginning.
