W1Z Micro Pdf417 Barcode With Byte Count Specifier - Honeywell E-Class Series User Manual

W1Z Micro PDF417 Barcode with Byte Count Specifier

Label format barcode ID (W1Z) to print a MicroPDF417 barcode.
MicroPDF417 is a 2 dimensional barcode capable of holding large amounts of data in
a small area. It provides a high level of redundancy and error checking. The Byte
Count specifier allows for data values 0x00 through 0xFF to be included within the
data strings without conflicting with the DPL format record terminators.

Parameters
See Behavior section below,
Behavior
Specified Length – The upper case Z identifies a Micro PDF417 barcode with a 4-digit
string length specifier. This allows values 0x00 through 0xFF to be included within the
data strings without conflicting with the DPL format record terminators. The four-digit
decimal data byte count immediately follows the four-digit column position field. This
value includes all of the data following the byte count field, but does not include itself.

Result
From the example, the barcode's data stream,
1W1Z0000000150100001214000PDF<0x0D>417, includes a Byte Count Specifier
(the portion in bold), where 0012 equals the four-digit decimal data byte count and
includes all bytes that follow until the end of the barcode data. Field termination is set
by the byte count. <STX>, <CR>, and <0x0D> all represent single byte values of
