Data Handling
Barcode Scans
When you successfully scan a barcode label, the barcode is both
transmitted from the unit and stored into memory, a unique
characteristic that allows the unit to function as a normal fixed barcode
reader when connected to the Homebase.
Transmitted data is terminated as instructed by
Function 03
. Stored data
is terminated by an end-of-data marker in memory, then terminated as
instructed by
Function 03
when it is output.
Keyboard Entries
When you press the
ENTER
key after a keyboard entry, the entered data
is stored in memory, but is not normally transmitted to the PC. This
can be changed by turning on the Keypress Echo option in
Function 03
.
Use of the Comma Key
The comma key can be used to delimit data fields. Normally, scanning
a barcode representing
A1000
followed by typing
10 ENTER
on the
keyboard would produce this in memory:
A1000
10
However, if you scanned the
A1000,
then typed a comma before entered
the
10
and
ENTER
, memory would contain this:
A1000,10
When downloading data to your computer, having related data on the
one line separated by a comma may make software programming
easier.
Editing Data
Because editing data on a two-line display would be impractical, the
Z4 DataTraq does not provide editing facilities for data stored in
memory.
If an entry is are made on the keypad but
ENTER
has not been pressed,
characters on the display may be deleted by using the backspace
«
key.
Once
ENTER
has been pressed, though, the line just typed cannot be
edited.
