ASP Portable Barcode Reader
Use of the Comma Key
The comma key can be used to delimit data fields. In the normal course,
scanning a barcode representing A1000 followed by typing 10 ENTER on the
keyboard would produce in memory:
A1000
10
However, by scanning A1000 then typing , 10 ENTER, memory would
contain:
A1000,10
When downloading to your computer, having related data on the one line
separated by a comma may make software programming easier.
Editing Data
Because barcodes themselves usually contain error checking, no facilities are
provided to alter barcode scans in memory.
If entries are made on the keypad but ENTER has not been pressed, characters
may be deleted by using the backspace « key. Once ENTER has been pressed,
the line just typed cannot be edited.
Editing data on a two-line display is impractical. Accordingly, we suggest you
adopt a method of identifying incorrect data, downloaded from the BCR, in the
programs used in the host computer system. Probably the most common
problem will be encountered during an inventory, where an identifying barcode
may have been scanned, but the quantity typed in is too high or too low. One
answer might be to re-scan the barcode and type in the correct quantity. When
the data is downloaded to the host computer, the receiving program could be
designed in such a way that when it finds a barcode scanned more than once, it
accepts as valid only the last read (with its associated quantity).
Your dealer will be happy to assist with suggestions to suit your application.
