SOFTWARE CONFIGURATION11977.5.5 Extending DOF Using Standard Acquisition Group (Cycle All InSame Phase)Multiple Image Acquisition Settings assigned to the same Acquisition Group (Standard), canbe configured and enabled to extend the reader's depth of field. During each reading phase,decoding will be attempted by applying each enabled Image Acquisition Setting (cyclically).Example:Read a 15 mil Data Matrix ECC 200 code covering a range from 140 to 320 mm (see 15 milreading diagram). The reading distance range is too long to be covered by a singleacquisition setting, so two acquisition settings could be used in which the first has a ReadingDistance of 195 mm and the second has a Reading Distance of 300 mm. When both areenabled, the reader cycles through the two settings effectively producing the extended DOF.NOTE: Cycling through Image Acquisition Settings that require changing theReading Distance parameter (for liquid lens models), drastically reduces theframe rate due to the liquid lens refocusing delay as well as by the number ofsettings simultaneously enabled. Therefore this may not be the best solutionfor high speed applications. For high speed applications it is best to use theAlternative Acquisition Groups (Input Select) feature described in par. 7.5.6.Otherwise use multiple readers set to different reading distances.Since many factors and parameters contribute to maximizing the reading process, it issuggested to use the VisiSet™ Standard Setup Wizard to set the different acquisitionssettings.NOTE: By default the Alternative Acquisition Group Select parameter isdisabled.Multi Image Acquisition Settings Procedure using Standard Setup Wizard:1. Using the Standard Setup Wizard set the first acquisition setting (default) for the 195 mmReading Distance. Save the setting to Permanent Memory.2. Through the Calibration Tool (Interactive Mode):a. Set Calibration>Image Acquisition Setting 1 - Status to Disabledb. Set Calibration>Image Acquisition Setting 2 - Status to Enabledc. Set LEDs And Keypad>Autolearning Setup>Image Acquisition Setting to 2d. Close the Calibration Tool3. Using the Standard Setup Wizard set the second acquisition setting for the 300 mmReading Distance. Save the setting to Permanent Memory.4. Through the Calibration Tool (Interactive Mode):a. Set Calibration>Image Acquisition Setting 1 and 2 - Status to Enabledb. Verify that the reader decodes at both distances then Close the Calibration Toolc. Send Configuration to Permanent Memory
