PC Control / Touch Control
3.10.15 Barcode reader
A barcode reader can be connected to the Titrando system to read in
sample data or other texts. When a barcode reader is connected to a
Titrando system with Touch Control then it is automatically entered into
the device list with default parameters. Barcode reader models which
can currently be connected can be found on the Internet under
www.titrando.com.
Select the Barcode input target for the barcode character string.
For PC Control Active input field means that the contents of
the barcode will be written into the input field in which the cursor is
currently located. With Touch Control Active input field means
that the barcode string will be written into the Input field of an
opened text or numerical input dialog. For the input targets Method,
Identification 1, Identification 2 and Sample size (value
only) the location can be anywhere in the dialog, the read-in string
will be written automatically into the selected input field. Only
numerical entries will be accepted for the sample size. Strings
which contain characters other than numbers and decimal
separators will be ignored.
With Touch Control you can also select the country-specific key
occupancy for the emulation of the PC keyboard under Keyboard
layout. This setting must be identical to that on the barcode reader
(see barcode reader documentation).
When the barcode reader is connected to a Titrando system with Touch
Control then the unambiguous identification of the manufacturer
(Vendor ID) and the USB address will be shown automatically.
When a string has been transmitted by the barcode reader and
accepted then this will be confirmed by an acoustic signal. If a Touch
Control is used for operating the Titrando system then data should only
be read in when the system is in the normal operating status (Ready),
i.e. when no determination is running.
