3 Customizing your OPN2002 and OPN2003
In the following section a brief overview is given on how to configure your OPN2002/3 for
your desired application.
3.1 Selecting the USB interface (VCP or MSD)
This batch demo application supports 3 methods of retrieving your barcode data file from
the OPN2002/3:
USB Mass Storage Device (MSD)
USB Virtual Com Port (USB-VCP) using NetO32 to retrieve the file
CRD2000 multicradle using NetO32 to retrieve the file (OPN2002 only)
After loading this software on the OPN2002/3 for the first time, the application will
automatically be reset to USB-VCP default.
If you would like to use your OPN2002/3 use USB Mass Storage Device, read the label
below.
(The labels below can be read without reading any SET/END labels)
More information on how to use your OPN2002/3 as USB Mass Storage Device will be
given in chapter 8.
To switch back to USB-VCP default (i.e. to load software) read the label below.
More information on how to use your OPN2002/3 as USB-VCP will be given in Chapter 7.
Independent of whether you configured your OPN2002 as Mass Storage Device (MSD) or
as USB-VCP, it’s allows possible to transmit your barcodes using the CRD2000 multicradle
in combination with the NetO32-file transfer application.
