............................................................................................................................................................ DATA ENTRY
All data is entered on the systems keypad. This keypad consists of 16 data entry keys, a DATA LOCK key, a DIVERT
LOCK key and a hidden error alarm. Both full travel and smooth face membrane keypads are available.
Two slightly different key entry formats are utilized. Continuation Options are selected by striking a single key while data
entry requires the operator to select the data entry location, key in the data and finally strike the ENTER key to terminate
the entry process.
Data Entry Format
The data displayed on any screen can be changed by the operator if one of the Continuation Options is EDIT. This option
is selected by keying in the access code sequence .00 Access to the data can not be obtained if the DATA KEY is in the
DATA LOCKED position. This data lock provides some security against unauthorized data access. Upon access to a data
display, a flashing cursor will be displayed on the screen at the location where the user may enter data. This cursor is a
flashing square box the size of a single character and is located at the right edge of the current data entry location. For
displays with more than one data entry location this cursor can be moved to other data locations, without chanqinq any of
the data on the screen, by using the left (<-) and right (->) arrow keys. The left arrow key moves the cursor back (or left or
up) through the data list whereas the right arrow moves the cursor forward (or right or down) through the data list.
The ENTER and ESCape keys have special significance during data entry. When the user strikes the ENTER key he
instructs the computer to use the data value exactly as shown on the display. If a new data value has been keyed in, the
new data value will be used. If the originally displayed data has not been changed ENTER will not change the data.
WYSIWYG -what you see is what you get-.
The ESCape key allows the user to escape directly and immediately from this display to the previous display. Any new
data value in the process of being keyed but not ENTERed will NOT be used; the previous data value will be retained.
As a new data value is being keyed character by character, the left arrow (<-) can be used to delete the previous character
entry. The left arrow can be thought of as a correction arrow.
The right arrow (->) will function exactly as the ENTER key.
The minus sign will not be recognized unless it is the first character entry.
Only one decimal point will be allowed per entry.
The user should not be intimidated by the keypad. The operation of this keypad, the ENTER, ESCape and arrow keys is
highly intuitive. The computer will not allow the entry of unrecognizable key sequences. The operator is encouraged to
experiment with all the keys until he is familiar with their functions and comfortable with their use.
