PHOTO TRANS % - (Photocell Transition Percentage)
When a lighting bus is used to control the lighting of the display
(see Figure 5-9), this parameter sets the point on the lighting bus
control below which the display brightness tracks the 500W
Series unit’s photocell. This field has a range of 0 (zero) to 99,
and is set to 25 at the factory.
PHOTO SLP/OFFST - (Photocell Slope/Offset)
These fields are equivalent to the SLOPE/OFFSET fields
described above, with the exception that they only control the
display lighting characteristics when the lighting bus control is
below the level specified in the PHOTO TRANS % field. Both
fields have a range of 0 (zero) to 99, and are set to 50 at the
factory.
