Display Setup
The meter’s front panel display is controlled by three types of ION modules: the
Display Options module, the Scroll module, and Display modules.
Display Options Module Settings
The Display Options module contains setup registers that hold data display
settings such as contrast level, backlight timeout, daylight savings time, and
update time. Settings in the Display Options modules are global, and affect the
entire set of front panel display screens.
Scroll Module Settings
The Scroll module determines the sequence and rate of scrolling for multiple front
panel display screens.
The Trigger outputs of Scroll module are linked to the inputs of Display modules.
When a pulse is sent from the Trigger output of a Scroll module to a linked Display
module, the Display module shows its information on the front panel.
