READING STATION OVERVIEW
The AV7000 camera reading system consists of two pieces:
1. A barcode reader/camera for acquiring images and locating and reading the codes
on a target.
2. A lighting system for illuminating the target codes to be acquired.
Most reading system applications use a network of multiple cameras.
All linear cameras need to know the moving speed of the targets to be acquired, so the
c
onveyor speed must be constantly measured. There are several ways to accomplish
this.
•
Optical Encoder Wheel (Tachometer): Used underneath a conventional conveyor.
The encoder generates a pulse per specified distance (mm [in]) of conveyor travel.
• I
nternal Tach: This is a software-generated pulse mimicking an encoder/tachome-
ter.
•
PGD100 Speed Detector: Used with tilt-tray or cross-belt sorters. This detector
uses a series of photoelectric sensors to determine the conveyor speed.
The position sensor (DM3610, RangeFinder, ligh
t curtain (DS2), or S85 Position Sensor)
can be used as a trigger source. When the height or left/right focus data measured by
