Single or Multi-Unit Tunnels and Arrays
Many AV500/AV900 reading system applications will read over a moving conveyor and
use a network of multiple devices.
• Optical Encoder Wheel (Tachometer): Used und
erneath a conventional conveyor.
The encoder generates a pulse per specified distance (mm [in]) of conveyor travel.
• Internal Tach: This is a softw
are-generated pulse mimicking an encoder/tachome-
ter.
A position sensor (DM3610, light curtain or S85 Position Sensor) is oft
en used as a trig-
ger source. When the height or left/right focus data measured by the sensor goes over a
certain
threshold, a package is entering the image valid start, and when it goes under
the threshold, the package is providing the image valid stop. Sometimes this sensor is
not sufficiently precise and an additional Presence Sensor input is used. When the
codes are located on more than one face of the parcel, more than one reader is neces-
sary (multi-camera reading station). In this case, one of the bar code readers (the Con-
troller) collects the information from all the sensors and
distributes it to the other
readers using a dedicated Ethernet connection. A CBX connection box is used to simplify
the connection of the camera to the other system components.
Airport Baggage Handling
Baggage handling system airport arrays use multiple scanners and controllers as neces-
sary to properly cover conveyors carrying passenger luggage through an airport baggage
handling sy
stem. Several cameras, a CBX and an SC5000 Controller are required. Some-
times a Redundant System is required to provide duplicate controller and scanner sta-
tions for improved reliability and performance.
Automated Parcel Sorting
Easy installation, maintenance, superior performance, and longer life-cycle make
AV500/AV900 a compelling solution for over-the-belt reading.
5.0/9.0 megapixel image captures where each single shot frames the entire area. One-
read
er-one-shot obtains maximum reading throughput. Image capture is associated
with the data of each sorted item and for any reporting or analysis purposes. Additional
devices can be used for scanning applications of large conveyors or multi-sided reading,
through Ethernet clustering, multiple readers can be effectively combined to extend the
scanning area.
