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
conveyor 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.
• Internal 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, light curtain (DS2), or S80 Position Sensor)
can be used as a trigger source. When the height or left/right focus data measured by
