Chapter 3 Quick Start Your Wasp WLP 4170 CCD Scanner is ready to go. The default settings of the Wasp WLP 4170 CCD Scanner have been pre-programmed for the most common bar code configurations. Use the "Setup & Configuration" sections only to customize the Wasp settings. Tip: Use the pre-printed "Bar Code Test Symbols" in Appendix A on page 30 as a test chart to begin practicing scanning.
Chapter 4 Bar Code Symbologies Bar codes are symbols consisting of a series of bars and spaces which can be applied to packages, cartons, bottles, and other commercial products. The bars and spaces in each symbol are grouped in such a way to represent a specific ASCII character or function. The interpretation of these groups is based on a particular set of rules called symbologies. Various symbologies have been developed for particular applications.
