5Integrated designAll components for lighting, optics, image acquisition(camera) and signal processing (CPU) are combinedin one unit and are mutually optimized to ensure thatreading codes is performed quickly, reliably and withvirtually no maintenance.Reliable code reading for DPMVarious original pre-processing algorithms are applied to allowdecoding even 2D codes that are difficult to read.Real time image transfer and storageImages with read errors (or all images) can be stored in themain unit. In addition, using the free utility tool - PDTOOL–images can be transferred to a PC and stored in specifiedorders in real time.2D code readers PD60/65Common features14 types of pre-processing are available. Settings are made bysimply selecting from a pull-down menu.We have significantly improved the accuracyof reading direct marking on metal (which ishighly problematic for automatic reading) andimage detection abilities by using our newpre-processing functions and library.Symbol reading errorWith weak stamping pressure With a coating of detergentRead OKSymbol reading errorRead OKDetergent is caught in thecode, making donuts shapes.The stamp is restoredby correcting the image.Pre-processingRead ErrorRead OKDetection Error 1 Read Error Read OKRead OKBlacken cellsEqualizeMake black points largerEqualizePre-processing Pre-processingImprovement ofread accuracy dueto pre-processing.No detergentWith detergentCompact and place-saving solutionCode reading even under difficult conditionsTraceability made easyImagestorage USBPDTOOL411/2007
