Trigger Optimization
Optimization Parameters (cont.)
High Density Symbols
Near Field
C1: Reads high density symbols
only at high resolution in near
field only; spends 375 mS
attempting to decode the symbol;
large region of interest that
extends beyond the symbol.
C2: Reads high density symbols
only at medium-low resolution in
near field only; spends 375 mS
attempting to decode the symbol;
region of interest that extends
somewhat beyond the symbol.
C3: Reads high density symbols
only, at low resolution in near
field only; spends 250 mS
attempting to decode the symbol;
small region of interest limited to
the symbol and its quiet zone.
(Rev 5 hardware and earlier only.)
Note: See the Optimization Guide
7-14
Low Density Symbols
Far Field
D1: Reads low density symbols
only at high resolution in far field
only; spends 375 mS attempting
to decode the symbol; large
region of interest that extends
beyond the symbol.
D2: Reads low density symbols
only at medium resolution in far
field only; spends 375 mS
attempting to decode the symbol;
region of interest that extends
somewhat beyond the symbol.
D3: Reads low density symbols
only at low resolution in far field
only; spends 250 mS attempting
to decode the symbol; small
region of interest limited to the
symbol and its quiet zone. (Rev 5
hardware and earlier only.)

Use C1 if you are
reading small or
medium high density
symbols and you need
reliable and moderately
fast decodes.
Use C2 if you are reading
small or medium high
density symbols and you
are more concerned with
decode speed than
decode reliability.
Use C3 if you are
reading small or
medium high density
symbols and you are
most concerned with
obtaining fast decodes.
Use D1 if you are
reading medium or
large low density
symbols and you want
reliable and moderately
fast decodes.
Use D2 if you are reading
medium or large low
density symbols and you
want a balance of decode
reliability and speed.
Use D3 if you are reading
medium or large low
density symbols and you
are more concerned with
fast decodes than reliability.
