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 scanner 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.
Last Item Sequence Number Received
The Last Item Sequence Number Received is written with the Item Sequence Number by the
EtherNet/IP client to acknowledge the receipt of the Item Data. If fragmentation is used, this value
isn’t written until the complete message is received.
