If the contents are incomplete, call your local Allen-Bradley representative for assistance.
2. Design the scanner system.
Each application must be evaluated carefully. Successful bar code scanning begins with quality bar
code symbols and the correct number, type, and location of readers, decoders, and package sensors.
Refer to the following when designing your scanner system.
•
Before setting up the system, calculate the expected number of scans per symbol. Make sure
the reader can view the number of scans it needs. If necessary, adjust the symbol speed and/or
the distance between bar-coded packages.
•
Position the reader at a distance from the symbol that is within the range specified. A read rate
test should be made to verify the range, and also to ensure optimum scanning and decoding.
•
Avoid aiming the reader perpendicular to the symbol, to avoid directly reflected laser light.
•
If a package sensor is used, position it so it can sense the package before the symbol reaches
the scan area.
Note: Make sure that the scan beam does not hit the sensor's reflector; the resulting glare can blind
the reader temporarily.
