Maximum Fragment Data Buffer Size
The Maximum Fragment Data Buffer Size is the length of the fragment buffer. This value must
be less than or equal to the Maximum Item Data Buffer Size. The valid range is 1 – 450. The
default size is 450 (no fragmentation is used).

Expected Number Of Barcodes Per Item
The DS6x00 supports Item Data packets with multiple barcodes. The Expected Number of
Barcodes Per Item is the number of barcodes embedded in the Item Data. The default size is one
barcode.
Item Status
The Item Status Code is the status of the current Item Data packet and is returned with every
Item Data transfer. The table below shows the status codes and their meanings.

Item Data Size
The Item Data Size is the total size of the Item Data. If the Item Data Size is greater than the
Maximum Fragment Data Buffer Size, fragmentation is used (see the fragmentation example at
the end of this section).
Item Sequence Number
The Item Sequence Number is incremented by one on every new Item Data production. The
Item Sequence Number is set to zero at power up. Once an Item Data packet is ready to
transmit, the Item Sequence Number is set to one. The Item Sequence Number reloads to one
since zero is an invalid number.
Fragment Sequence Number
The Fragment Sequence Number is set to one on the first fragment of the Item Data production.
The Fragment Sequence Number is incremented by one on every new fragment. If
fragmentation isn’t used, this value is fixed at one.
