Macro PDF Transmit / Decode Mode Symbols

Parameter # BCh

Select one of the options below for handling Macro PDF decoding. In Buffer All Symbols the imager 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.
•
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 captured and decoded. Use the beeper and LED
signals provided with the Symbol MS440X 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
decoded. Use the parameter Flush Macro Buffer on page 11-80 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 Tabl e 11 -6). When
selecting this mode, enable Transmit Macro PDF Control Header on page 11-79. Also use the beeper and
LED signals provided with the Symbol MS440X 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 imager’s BEEPER_ON signal is not used to drive a beeper. In the other modes,
some Macro PDF imaging sequences provide audible feedback only, so if BEEPER_ON is not used no user
feedback is provided. In Table 11-6, 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.
