THE ROLLCALL MENU SYSTEM
(See `ARC130S Menu System' drawing on
previous page)
All operational parameters and selections are
made using a system of menus displayed in two
LCD windows.
Menus are selected by push buttons and further
menu selections made by rotating a spinwheel and
pressing a push button.
The spinwheel also allows continuously variable
parameters, e.g. Gain, to be adjusted and the
setting to be seen in the LCD window.
Various specific operations may be achieved by
operating dedicated push buttons.
The system may be considered structured as a set
of menus and sub-menus that are displayed in the
central LCD window. The left hand LCD window
will display the current input/output standard
selections of the unit and information messages.
The DISPLAY buttons allows the information
displayed to toggle between the modules current
setup and more detailed data including software
version etc.
The highest level menu is called the Main Menu
and contains the names of the lower-level menus
that may be scrolled through using the spinwheel.
The sub-menu may be then be selected by
pressing the push button adjacent to the
arrowhead in the text line of the menu name.
This sub-menu will then be displayed in the window
and will have the option of selecting another sub-
menu in the same manner, or allow the adjustment
of a particular parameter. Parameters enabled will
appear as highlighted reverse text (white text on a
black background)
Note that the spinwheel will be operative when the
LED labelled SCROLL is illuminated, indicating that
a menu with more than four text lines is being
displayed. Operating the spinwheel then allows the
other text lines to be displayed.
