Noread Message
Default: NOREAD
Options: Up to seven ASCII characters (except a NUL).
Allows you to define any combination of ASCII characters (except a NUL)
up to seven characters as the noread message.
The noread message, if enabled and if no bar code label has been decoded,
will be transmitted to the host at a timeout or the end of a read cycle.
Noread Message (enable/disable)
Default: Enabled
Options: Enabled, Disabled
Note: If Noread Output is enabled, the noread message will only output if Bar
Code Output is also enabled.
Allows you to enable or disable the noread message.
Bar Code Output
Default: Enabled
Options: Enabled, Disabled
Allows you to choose whether or not to send label data (or noreads) to the
host. When disabled, a label is decoded and the read cycle transpires as
usual, but neither label data nor the noread message is transmitted to the
host. All decoder counters are updated, and the number of good reads or
noreads can be obtained via operational commands.
