Macro PDF Transmit / Decode Mode Symbols
Parameter # BCh
Select one of the options below for handling Macro PDF decoding. In Buffer All Symbols the scanner 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 scanner 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 on page 5-91 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; see Table 5-6).
When selecting this mode, enable Transmit Macro PDF Control Header on page 5-90. Also use the
beeper and LED signals provided with the scanner to ensure proper user feedback.
•
Passthrough 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 scanner’s BEEPER_ON signal is not used to drive a beeper (see Table 2-3 on
page 2-10 and Table 3-3 on page 3-10). 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. In Table 5-6,
all actions marked No Transmission provide no feedback unless the BEEPER_ON signal is used. By
using Passthrough All Symbols mode every user decode is transmitted to the host where the host
software can provide the appropriate feedback.
