Macro PDF Features
Macro PDF is a special feature for concatenating multiple PDF symbols into one file.
The decoder can decode symbols that are encoded with this feature, and can store
more than 64 Kb of decoded data stored in up to 50 MacroPDF symbols.
CAUTION: When printing, keep each Macro PDF sequence separate, as each sequence has unique identifiers.
Do not mix bar codes from several Macro PDF sequences, even if they encode the same data. When scanning
Macro PDF sequences, scan the entire sequence without interruption. When scanning a mixed sequence, two
long low beeps (Low/Low) indicates an inconsistent file ID or inconsistent symbology error.

1. The beep only sounds if the *BEEPER_ON signal is connected.
2. The column marked T indicates whether the symbol is transmitted to the host.
N = No transmission.
Macro PDF Transmit / Decode Mode Symbols
Select one of the options below for handling Macro PDF decoding. In Buffer All
Symbols the decoder can handle sets of up to 50 maximum-sized Macro PDF
symbols. In all other modes there is no limit to the size of the MacroPDF set.
Buffer All Symbols / Transmit Macro PDF When Complete: This transmits all
decode data from an entire Macro PDF sequence only when the entire
sequence is scanned and decoded. Use the beeper and LED signals provided
with the MS842 when using this mode to ensure proper user feedback. If the
decode data exceeds the limit of 50 symbols, there is no transmission because
the entire sequence was not scanned. Use the parameter Flush Macro Buffer to
purge the buffer.
Transmit Any Symbol in Set / No Particular Order: This transmits data from
each Macro PDF symbol as decoded, regardless of the sequence (although
some error handling is performed). When selecting this mode, enable Transmit
Macro PDF Control Header. Also use the beeper and LED signals provided with
the MS842 to ensure proper user feedback.
