Macro PDF Transmit / Decode Mode Symbols
Select one of the options below for handling Macro PDF decoding. In
Bu
ff
er 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 Macro PDF set.
Bu
ff
er 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 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 Bu

er
to purge the

er.
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

r. Also
use the beeper and LED signals provided to ensure proper user feedback.
Pass through All Symbols
- This transmits and decodes all Macro PDF symbols and
performs no processing. In this mode the host is responsible for detecting and parsing the
Macro PDF sequences.
Use this mode when the decoder’s B
EEPER_ON
signal is not used to drive a beeper. In the
other modes, some Macro PDF scanning sequences provide audible feedback only, so if
BEEPER_ON
is not used no user feedback is provided. All actions marked
No Transmission
provide no feedback unless the
BEEPER_ON
signal is used. By using
Pass through All
Symbols
mode every user decode is transmitted to the host where the host software can
provide the appropriate feedback.
