Configure Performance Settings
The Performance step allows you to optimize the scanner for Direct Part Mark (DPM)
decoding. A DPM is a permanent mark created by laser etch, chemical etch, or other
method, directly on a substrate. DPMs are often harder to read than other symbols, and
may require a few attempts before finding optimal settings. The Decoder Effort slider has
four settings: Level 1, corresponding to Min on the slider; Level 2; Level 3; and Level 4,
corresponding to Max on the slider. As Decoder Effort is moved toward Max, the decoder
spends an increasing amount of time trying to decode the symbol.
In Level 4, you can also enable the Enhance option, which improves readability by adding
an image pre-processing operation (Shrink Dark or Grow Dark) to improve decode performance
on marks whose cells are not properly formed. You can also select the size (Small,
Medium, or Large) of the area or "pixel neighborhood" in which the pre-processing operation
is performed. Small = 3 x 3 pixels, Medium = 5 x 5 pixels, and Large = 7 x 7 pixels.
The Illumination Control options are:
• Direct: White LED illumination only. Recommended for use with dot-peened symbols.
Tilt the part 30° to avoid specular reflection when using Direct illumination.
• Indirect: Red LED illumination only. Recommended for use with laser-etched symbols
on curved, rough, grainy, highly-reflective, or visibly-machined surfaces or cylinders.
• Cycle: Alternates between Direct and Indirect illumination, starting with the type of
illumination used during the last successful decode.
Examples of Performance Configurations
• Level 4 (Maximum) Decoder Effort;
• Enhance – Shrink Dark pre-processing operation enabled;
• Medium-sized pre-processing area;
• Illumination Control set to Cycle.
