Autodiscriminate
Although
Autodiscriminate is not a configuration command, but it is included here as
a convenient tool for enabling most symbol types.
Note: If using an I 2/5 symbol, verify that the number of characters in the symbol
being scanned matches the symbol length enabled for the I 2/5 symbol type (default is
10 and 6).
Usage:
If the background is darker than the symbol, then enable black back-
ground.
Typically the background is white; but on PCBs for example, they can be
black.
Definition:
Allows the user to choose which symbol background (spaces and sur-
rounding medium) the reader can read.

symbology.

Length, etc. These need to be setup individually.

PDF417, Micro PDF417, and RSS. The user may also individually disable/
enable each symbology type.
