VIP-4060 Configuration Tabs
Under normal conditions, ERTD dimming takes precedence over all other dimming functions including
V-Max
™
signal. However, when activated, the thermal dimming function overrides all dimming modes
including ERTD and V-Max
™
signal.
Thermal dimming is triggered automatically during temperature
extremes to preserve the life of a display’s electrical components.
When thermal dimming is active, a visual temperature gauge is
visible to the right of Dimming mode drop-down tool. Refer
to
Figure 59
.
Auto
Auto
uses light sensor information to automatically adjust dimming values according to ambient conditions.
Values vary to reflect the information received from the light sensor.
Dimming is 100 percent of the maximum during the day or in bright areas. At night or in dim areas, the
dimming value is a much lower percentage.
Manual
Manual
allows the user to enter a dimming value with the slider bar. This
value becomes the current setting for the display and the display remains at
the selected brightness level until it is adjusted. The range is from 1 to 100
percent. Refer to
Figure 60
.
Moving the slider bar to the right adjusts the maximum light out of the display
and adjusts all color levels equally by the percentage indicated. For example,
100 percent means a full white image shows at the maximum light output
of the display. A level of 50 percent means a white image shows at 50 percent of the maximum light output
capacity of the display.
GPS
GPS
uses the display’s location to calculate
dimming. Calculations can be based on either
GPS Configuration
values entered under the
Configuration
Tab or GPS sensor information.
• GPS Configuration:
If no GPS sensor is
available, dimming calculations are based
on the information entered under the
GPS
sub-tab of the
Configuration
tab. Refer
to
Figure 61
.
• GPS Sensor:
When the
GPS
option is
chosen, the system first checks for a GPS
sensor on the sign. If a GPS sensor is
available, dimming calculations are based
on information gathered from the sensor.
ERTD
Enhanced Real-Time Data (ERTD) is a communication protocol which uses scripts to define how the
VIP-4060 system controls display dimming.
Ertd
overrules all other dimming modes except when thermal
dimming is active. Refer to
Section 5
for additional information.
