DOT-MATRIX DISPLAY
Additional signal and status monitoring is provided via the four-digit dot-matrix display located at the card-
edge. The card-edge pushbutton and toggle-switch are used to navigate through the display menu. Figure
4-2 provides a quick reference to the display menu structure.
Pressing the pushbutton advances the display to the next menu level. The toggle-switch may then be used
to move up or down through selections of that menu level. Select BACK to return to the top menu level.
CTRL menu items have user-adjustable configuration values associated with them. STAT menu items
display operating conditions or configuration values, but do not allow adjustment.
If a specific menu selection has a configuration value associated with it, then this may be changed using
the toggle switch. Pressing the pushbutton will apply the displayed value and return you to the previous
menu level.
The most recent user selection will be maintained in non-volatile memory in the event of power loss to the
module.
