Example 2:
The following sample illustrates the serial command sequence for configuring the engine for the factory
default settings, disabling Code 128 scanning, and adding a “G” as a configurable prefix.
Commands for features that require sequences of multiple bar codes for activation (i.e. prefixes, suffixes,
and timeout features) should be sent in the same order that they are normally scanned.
