2.1.2 How to scan
AR-3100/3200 emits a light bar when it is scanning.
This bar needs to cross the bar code horizontally to
decode it.
2.1.3 Work with the ASCII table
Sometimes, you might need to send some control
characters that can’t be typed or enter characters
without a keyboard. You can do it by using ASCII
codes.
In
Appendix B
, you'll find the ASCII table. Both
column and row numbers are hexadecimal. The ASCII
code of a character is the combination of a column
and a row number, where the column comes first.
For example, the ASCII code of BEL is "07" and the
number sign (#) is "23." You can use the bar codes in
Appendix D
to scan ASCII codes.
