Menu Navigation
The digital operator keys operate on three
levels, the menu level, the sub-menu level and
the entry level. At the menu level, they function
to navigate between menus or sub-menus. At
the sub-menu level, they navigate between sub-
menus or menu items. At the entry level, they
are used to adjust values or select options. Six
(6) keys are used for this navigation, they are:
1) The up arrow key.
2) The down arrow key.
3) The left arrow key.
4) The right arrow key.
5) The “ENTER” key.
6) The “ESCAPE” key.
Digital Operator Keys
How these keys operate is dependent on the
“level” (i.e. menu, sub-menu or entry level.) In
general, the “ENTER” and “ESCAPE” keys
control the level. That is the ENTER key used to
move to a lower level and the ESCAPE key is
used to move to a higher level. The arrow keys
control movement. With the up and down arrow
keys controlling vertical position. And the left
and right arrow keys controlling horizontal
position.
Navigation at the Menu Level
At the menu level, the up and down arrow keys
cause the display to show the sub-menus. The
side arrow keys cause the display to select
which menu is active. When the end is reached
(either up, down, left or right), pressing the same
key will cause a wrap around.
Each menu will remember the last accessed
sub-menu. The left and right arrow keys will
navigate between these last active sub-menus.
This remembrance of last active sub-menu is
volatile and will be lost at power down.
When any sub-menu is displayed, pressing the
“ENTER” key will place the operator in the sub-
menu level.
Navigation at the Sub-menu Level
When in the sub-menu level, the SUB-MENU
LED on the digital operator is lit. At the sub-
menu level, the positioning keys work slightly
different than they did at the menu level. The up
and down arrow keys now select separate items
in the sub-menu.
At any time pressing the “ESCAPE” key will
return to the menu level. Upon exiting a sub-
menu via the “ESCAPE” key, the last item
number is “remembered”. The next time this
sub-menu is entered, it is entered at the
“remembered” item number.
This feature can be used to obtain quick access
to two monitor values. Two menus one labeled
Display 1 D0 and one labeled Display 2 D0 have
the same display items. One item can be
selected one under the Display 1 menu and
another under the Display 2 menu. The left and
right arrow keys can then be used to move back
and forth between these two display items.
Remember, that the “remembering” of sub-
menus and sub-menu items is volatile and is lost
at power-down.
