Notes:
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.
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 decoder’s BEEPER_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 Tranmission
provide no feedback unless the BEEPER_ON
signal is used.
