When setting the dimming curve with the dimming control set to external input (EXT 

5V/EXT 14V/ EXT 28V), the X-axis of the dimming graph will read VOLTAGE and will 

range from 0 to (5, 14 or 28). This represents the voltage input of the lighting bus and 
shows the current input with the vertical blue line. The Y-axis represents brightness of 

the display. It will track the dimming curve with the horizontal blue line as the input 

voltage increases or decreases. With a lighting bus input, the dimming curve adds a ‘low-

level output’ feature. This allows the unit to be set to a high-brightness level to maintain 

daylight visibility when the lighting bus is turned down very low or off, as it may be 

during daylight hours. The best method for setting the dimming curve is to simulate the 
range of lighting inputs or conditions to match other instruments. This is best done after 

installation, in the actual aircraft instrument panel, but can be simulated in various 

environments. See Figure 4.10. 

 

1)

 

Change the lighting bus input until the vertical blue line matches (or nearly 

matches) the yellow highlighted point on the graph. 

2)

 

Adjust the control knob to increase or decrease the brightness of the display 

to the desired level at that lighting bus position (the point will move up or 

down, respectively). 

3)

 

When satisfied, press the control knob. 

4)

 

The next point will be highlighted.  

5)

 

Repeat Steps 1-4 for each point on the sloped line of the graph. 

6)

 

The next highlighted point will be on the vertical zero line. As the lighting 

bus is turned down or off, there may be a point where it should default to a 

set level (typically for daylight visibility). Adjust this dot horizontally with the 

control knob to set the low-input level of the lighting bus where the default 

brightness takes effect. You can verify where this occurs by adjusting the 

lighting bus input. Press the control knob to accept the position chosen. If 
this point is not set, the display will follow the dimming curve previously 

programmed and will be respond to the position of the first point when the 

lighting bus is turned off.  

7)

 

The next highlighted point will set the default low-input brightness. With the 

lighting bus input to the left of the previous set point, adjust the brightness 
up or down to the desired level. Press the control knob to accept the position 

chosen.

CONFIGURE AIRCRAFT 

 

The CONFIGURE AIRCRAFT menu option opens the sub-menu shown below in Figure 4.11. Note the 

sub-menu title at the top of the screen and indication (>) that there is a parent menu associated with 

it. The CONFIGURE AIRCRAFT will return the user back to the CONFIGURE MENU.
