7 Installing drivers
7.1 USB-VCP drivers
To be able to communicate with the barcode readers using USB-VCP, you will need to have Opticon’s USB driver
installed on your PC. This driver can be found on our website on the 'Service and Support' page.
www.opticon.com/SERVICE-AND-SUPPORT.aspx
The driver can be found in the section called 'Software' and then selecting the OPN2004, OPN2005 or PX20 on the
following page.
USB Drivers Installers.exe
USB-VCP driver for Windows 2000 , Windows XP (32bit) & Windows Vista/7 (32bit)
USB-VCP driver for Windows XP (64bit) & Windows Vista/7 (64bit)
After installing the USB driver, you can connect your barcode reader to USB using the mini-USB cable. Windows will
then automatically install a virtual COM port on your PC, which can be selected in various applications, like Appload,
Hyperterminal, OseComm32 and NetO32.
8 Using the Mass Storage Device (MSD) interface
When the USB-MSD interface has been selected (see chapter 3.1) the barcode readers will behave like USB thumb
drives when connected to USB.
Any scanned barcodes will be stored in a comma separated value file called ‘SCANNED.TXT’, which can be
copied/moved from the barcode reader using a file browser.
Due to the limited amount of flash memory inside the barcode readers the size of the file system is rather small,
being about 1MB. This is enough space for storing barcodes, but not for using the barcode readers as a portable hard
drive.
Important notes:

When deleting ‘SCANNED.TXT’ also delete the local files 'SCANNED.TMP' and 'SCANNED.IDX' from the disk as
well, because those are the files the barcode terminal is actually using, while 'SCANNED.TXT' is merely an export
of these files.

Editing 'SCANNED.TXT' will have no effect and will be reverted back to its previous state as soon as the USB cable
is subsequently connected again.

Editing 'SCANNED.TMP' will cause 'SCANNED.IDX' (fast search index-file) to become corrupt, which can cause the
barcode reader to crash!
