KDC200 Programming Manual
How many barcodes can we store?
The number of barcodes that can be stored in these bytes depends upon the size of the barcodes
Example: If only UPCA barcodes are scanned and the check digit is not transmitted, then each barcode takes up
11 (barcode data) + 2 (length and type) + 4 (time stamp) = 17 bytes. The maximum number of UPCA barcodes
that can be saved is 204,800/17 =12,047. However, the maximum number of barcodes can be stored is 10,240.
Therefore, KDC200 can store 10,240 UPCA barcodes.
If different length barcodes are mixed, user cannot compute a priori what the maximum number of barcodes is.
What happens when this buffer is full?
When the internal flash memory is full, KDC200 displays buffer full message and ignores the command to scan
barcodes.
