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.
