Perform testing with the actual ABR using application-specific codes to evaluate whether maximizing application
performance requires adjustments to the hardware/software configuration with respect to the Reference Conditions
given under each diagram
•
The ratio of the Vertical FOV width with respect to the Horizontal FOV width in the diagrams depends on the model
For WVGA models, it is about equal to 0.64; specifically 480/752 (that is, FOV
◦
For 1.2 MP models, is about equal to 0.75; specifically 960/1280 (that is, FOV
◦
•
The reading distance ranges are measured from the reading window surface
•
The max theoretical Line Speed values for each diagram can be calculated using the formula in
Speed and Exposure Calculations
•
Common software parameter settings:
For all ABR 3000 models (except where specified differently) reading all 1D code symbologies - Processing
◦
Mode = Standard
For all ABR 3000 models (except where specified differently) reading 2D code symbologies - Processing
◦
Mode = Standard; Code Contrast = Low; Decoding Complexity = Medium
•
When defining a hardware/software configuration for the ABR for conditions different from those of the reference
diagrams, keep in mind the following rules:
◦
Changes in Exposure Time act directly proportional to the luminosity of the image and inversely proportional
to the maximum code reading movement speed. Consequently, reducing the Exposure Time by half,
reduces the luminosity of the image by half but doubles the theoretical code reading movement speed
Changes in Gain act directly proportional to the luminosity of the image. Increasing the Gain value however,
◦
can reduce the quality of the acquired image
