Overview
This appendix contains reference data pertaining to enab-
ling bar code algorithms and interpreting bar code data.
Collecting and decoding bar code data are built-in features
of wireless stations. The wireless station is programmed to
support a variety of bar code scanning devices and decode
all major bar code types.
Specific bar code algorithms are enabled either by scanner
orders from the host computer, or by the terminal operator
using the wireless station’s firmware menus. Once a wire-
less station correctly decodes a bar code, the data is encoded
with descriptive data about the decoded symbol.
The wireless station employs unique ASCII command codes
to enable certain types of bar code algorithms and to format
bar code data for return to the host computer. You can im-
prove response time for your network by knowing the bar
codes you use and limiting the wireless station to only those
codes.
