OPERATIONAL DESCRIPTION
2.1 Chapter Objectives
This chapter describes:
•
Overview of how the SCANTEAM 6180 works, including scanning
aperture, depth of field and scanning velocity.
•
Reading and decoding a bar code symbol. Description of print
contrast, high and low density bar code symbols.
•
Discussion of RS–232 interface and external power options.
2.2 Main Elements of the 6180 Bar Code System
The major operational elements of the SCANTEAM 6180 include the
scanner optics, the digitizing electronics and the decoding circuitry.
The key components of the scanner optical system are the illumination
source (LED) and the illumination sensor (photodiode). Both the LED and
photodiode are positioned directly behind a specially designed lens in the
scanner body.
Cable connections are made directly to the board and exit the scanner body
through a flexible strain relief at the end of the wand handle. The integral
cable shield affords EMI and associated drain protection to output signals.
