400W Series Installation Manual Page 5-11190-00356-02 Rev. ESLOPESets the sensitivity of the display brightness in proportion to changes in the input level. The higher thenumber, the brighter the display is for a given increase in the input level. This field has a range of 0(zero) to 99, and is set to 50 at the factory.OFFSETAdjusts the lighting level up or down for any given input level. This field has a range of 0 (zero) to 99,and is set to 50 at the factory. This may also be used to match lighting curves with other equipment inthe panel.NOTEIf a lighting bus (any selection other than PHOTO) is selected, and the lighting buscontrol is turned to its minimum (daytime) setting, the display brightness tracks the400W Series unit’s photocell using additional parameters (PHOTO TRANS % andPHOTO SLP/OFFST) described below.PHOTO TRANS % - (Photocell Transition Percentage) When a lighting bus is used to control thelighting of the display (see Figure 5-10), this parameter sets the point on the lighting bus control belowwhich the display brightness tracks the 400W Series unit’s photocell. This field has a range of 0 (zero) to99, 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 theyonly control the display lighting characteristics when the lighting bus control is below the level specifiedin the PHOTO TRANS % field. Both fields have a range of 0 (zero) to 99, and are set to 50 at thefactory.5.3.8 GPS DATE/TIME SETUP PageThis page displays the GPS date and time. (see Figure5-11).Figure 5-10.
