Configuring Predefined Imager Modes
When using a 2D model (SG20THP or SG20THC), you can optimize
the reading performance of the scanner by adjusting certain
parameters. Since there are many parameters that can be adjusted, we
recommend using the pre-defined imager settings to quickly set up
your imager for optimized reading. The pre-defined imager settings
take in to account the type of bar code, environment and reading
surface.
There are 4 pre-defined imager settings:
• 1-Dimensional bar codes only
• Standard 1-dimensional and 2-dimensional bar codes
• 1-Dimensional and 2-dimensional bar codes in a bright
environment
• 1-Dimensional and 2-dimensional bar codes with reflective
surface (shiny labels)
Select the pre-defined imager setting that best suits your needs:
1D bar codes only
Standard 1D and 2D bar codes (*)
Standard 1D and 2D bar codes, bright environment
Standard 1D and 2D bar codes, reflective surface
