5.1. Read mode options
The following read modes are available:
Single read:
When a bar code has been decoded, the
reader will be turned OFF. The reader must be
triggered again to read another label. This
option and 'Disable trigger' can not be
programmed at the same time.
Multiple read:
When a bar code has been decoded, the
reader will stay ON for a time as set by 'Read
time options' or indefinitely if the trigger switch
has been disabled. The same label can only be
decoded again after the label has not been
detected for a number of scans.
Continuous read:
The reader will produce as much data as it can
decode regardless whether it is the same or
not. This mode is mainly used for
demonstration and diagnosis.
Disable trigger:
This is applicable to readers which have a
trigger switch. When this option is selected, the
reader will stay ON all the time.
Note: Selecting this option for a laser reader
means that the laser diode is ON continuously,
which may reduce the lifetime of this
component. Also local legislation may require
that the trigger switch is always enabled.
Therefore it is recommended not to disable the
trigger switch for laser readers.
Add-on wait mode:
Used if UPC/EAN with add-on is enabled. The
reader searches within the selected time for a
valid add-on code. If a valid add-on code is
found, the reader transmits the data
immediately. If nothing is found behind the
code, the reader will transmit the data without
add-on. If something is found behind the code,
the reader ignored the code in case it is not a
valid add-on.
Trigger repeat:
This option makes it more easy to select a
single bar code from a sheet filled with bar
codes. If the trigger switch is pressed once, the
laser beam is on during the configured read
time. The laser beam can now be moved to the
required bar code. If the trigger switch is
pressed again, the bar code is decoded and
transmitted. If the read time expires, the laser
switches off and the trigger sequence should
be repeated. If the read time is set to 0, then if
the trigger switch is pressed, the laser is on, but
does not accept bar codes. As soon the trigger
switch is released, the barcode is decoded and
transmitted. Support for this option is reader
dependent.
Structured append time out:
When a bar code consists of multiple physical
bar codes, this time out value is used. The next
bar code must be read before this time out is
expired. The time out value is between 1 and
255 seconds. This value can be configured by
reading 1 up to 3 direct input numeric
characters from chapter: String options.
Default the structured append time out is set to
30 seconds.
