Front Panel Display

LCD
The primary local interface for the Millennium II is an eight-line LCD assembly mounted to the front of
the primary GPS cabinet door. This user interface is a panel that includes a backlit LCD module, two
sections of status LEDs, system voltage test jacks, and an array of simple push-button controls. This
controller supports multiple LCD display assemblies. It is backwards compatible to both existing
Millennium LCD assemblies L51 and L50 shown in Figure 10-5. It is also compatible with the enhanced
L52 LCD display assembly (see figure 4-6) specifically developed for the Millennium II. This new display
assembly is compatible to existing GPS cabinet doors and is functionally backwards compatible to the
Millennium. It looks very similar to the L51 option. LCD assembly, but the L52 also provides a built-in
audible alarm and digital contrast adjust that are only available when used with the Millennium II
controller.
