Macro PDF417
Macro PDF417 is an optional feature for PDF417 that allows the data from
multiple symbols to be combined into a single message. Enabling this feature
causes the reader to buffer Macro PDF417 symbols and to assemble them in the
correct order, regardless of the order in which the symbols are scanned. When
this feature is disabled, the reader transmits the data from each symbol
independently, in the order it is scanned.
Default = Buffer.
Show Macro Control Blocks
Turning on this feature causes the Macro PDF Control Block to be transmitted at
the end of the encoded data, except when the reader has successfully buffered
and assembled each symbol into a single message. The Control Block is
transmitted as defined in
AIM Uniform Symbology Specification PDF417 using
an escape sequence. The Control Block begins with the escape character ’\’
(ASCII 5C hex), and any natural occurrence of the ’\’ in data is replaced by ’\\’.
This mode is recommended when the host system is capable of interpreting the
Control Block. When this feature is disabled, the Control Block is not transmitted.
Default = Don’t Show Control Blocks.
