Symbol MS3204 Scan Patterns
The Symbol MS3204 generates four scan patterns based on the software command received at the interface.
These patterns are Smart Raster, Semi-omnidirectional, Omnidirectional, and High Density Single Scan Line. The
raster pattern can be used to read 1D bar codes and PDF417 symbols. The omnidirectional pattern reads 1D bar
codes in an omnidirectional manner.
Smart Raster Scan Pattern
The Symbol MS3204 can create a single line which opens vertically to read PDF417 symbols using the Smart
Raster feature. This feature autodetects the type of bar code being scanned and adjusts its pattern accordingly,
providing optimal performance on 1D, PDF417, GS1 DataBar, and Composite codes.
Figure 3-4 Raster Scan Pattern
Semi-omnidirectional Scan Pattern
The semi-omnidirectional pattern is an alternative to the full omnidirectional pattern that scans highly truncated 1D
and GS1 DataBar bar codes. Present bar codes horizontally with no more than a 20
o
tilt.
