Alpha-Numeric Keypad - HORNER APG XL10 PRIME OCS User Manual

MAN1029-10-EN_EXL10_XL10P_UM
On objects that represent non-discrete information, more action may be required beyond that of simply
touching the object. For example, the slider object requires the operator to touch and slide the control in
the direction desired. Alternately, alpha-numeric entry objects invoke a pop-up alpha-numeric keypad for
additional user input. The alpha-numeric keypad is discussed below.
NOTE: If the numeric entry object displays >>>>>>>, the value is too big to display in the field or is above the
maximum for an editable field. Likewise, if the numeric entry object displays <<<<<<< in a numeric field, the
value is too small to display or is below the minimum for an editable field.

14.3 Alpha-Numeric Keypad

To allow entry of a specific number or text, several of the input objects invoke a pop-up alpha-numeric
keypad when the object is touched. An example of the alpha-numeric keypad invoked from a numeric input
object is shown in Figure 14.2. Once invoked, the operator may touch the appropriate keys to enter a
specific value. When entering a value, the alpha-numeric keypad is in one of two modes [new-value or edit-
value].
New-Value Mode
Generally, when the alpha-numeric keypad is first invoked, it is placed in new-value mode. Initially, the
alpha-numeric keypad displays the current value with all the digits being highlighted. Once the first digit is
entered, the current value is erased from the display and the new digit is placed in the first location.
Thereafter, no digits are highlighted, and new digits are added to the rightmost position while the other
digits are shifted left.
Edit-Value Mode
Edit-value mode may be entered from the initial new-value mode by pressing either the left or right arrow
key before any digit key is pressed. The result will be a single character highlighted. The user may then
either touch a key to change the digit at the selected position or the up and down arrows may be used to
add or subtract (respectively) from the selected digit. The user may then use the left or right arrow keys to
select a new position.
