9.3.4 Equation to Determining Potential Number of Stored
Barcodes
The number of barcodes that can be stored in the KDC memory depends on 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 (added bytes) + 2 (length and type) +
4 (time stamp) = 19 bytes. The maximum number of UPCA barcodes that can be saved is
204,800/19 =10,778. However, KDC has limited the maximum number of barcode as
10,240 and users can't store more than 10,240 barcodes in 2.85/86 version. 3.0x version
allows user to store maximum 204,800 barcodes.
9.3.5 Data Buffer Full
When the data buffer is full, the KDC displays a message, Buffer Full, ignoring any
command to scan barcodes. You must reset the data buffer to continue data collection.
