z Passthrough All Symbols: This transmits and decodes all Macro PDF symbolsand performs no processing. In this mode the host is responsible for detectingand parsing the Macro PDF sequences.Use this mode when the decoder’s BEEPER_ON signal is not used to drive abeeper. In the other modes, some Macro PDF scanning sequences provide audiblefeedback only, so if BEEPER_ON is not used, no user feedback is provided. Allactions marked No Tranmission provide no feedback unless the BEEPER_ONsignal is used.By using Passthrough All Symbols mode every user decode is transmitted to thehost where the host software can provide the appropriate feedback.Transmit Macro PDF Control HeaderWhen enabled, this activates transmission of the control header, which contains thesegment index and the file ID, in Macro PDF symbols. For example, the field maybe: \92800000\725\120\343. The five digits after the \928 are the segment index (orblock index), and \725\120\343 is the file ID.Enable this when selecting Transmit Any Symbol in Set / No Particular Order for theMacro PDF Transmit /Decode Mode Symbols, and disable this when selectingBuffer All Symbols / Transmit Macro PDF When Complete. This parameter has noeffect when Passthrough All Symbols is selected.71Copyright 2013 Unitech Electronics Co., Ltd. All rights reserved.
