5.4.1 Configure the number of display groups
This procedure configures the number of display groups for the LCD.
A display group defines a group of variables. The RMC displays them on its LCD so they are viewable
without using PCCU.
The RMC ships with a standard or a custom configuration. Either configuration might include a factory
default display group for basic station parameters display. Figure 5-5
shows an RMC with a single
display group configured. In this example, the default display group is named Factory Default (other
configurations use Station as the group’s name). This group shows 7 display items with specific
assignments. The LCD displays the values of these parameters. Three Spare items are unassigned,
but configurable. The LCD only displays a value for these items when they are defined.
