Using the USB-VCP and CRD2000 Interface

Configuring the Host PC or Laptop with NetO32

When the USB-VCP interface has been selected, the barcode database file can be transmitted to a
remote PC or laptop using NetO32. The data is transmitted by either a mini-USB cable (USB-VCP)
or by the CRD2000 multi cradle (OPN2002 only). To be able to receive the files on the host, you will
need NetO32 to be installed. The latest version of NetO32 can be downloaded from our website (see
NetO32). More information about additional Neto32 features that are not described in this manual
can be found in the NetO32 help file.

Using the CRD2000

Setup

When using the CRD2000 multicradle, certain configurations have to
be made to correctly synchronize multiple OPN2002s that all want to
transfer a file to the host at the same time.
First of all, the RS232 settings have to be correctly configured. Besides
selecting the correct COM-port of the CRD2000, you will also have to
select the correct baud rate and other RS232 settings. The default NetO32
settings are shown in the screenshot below. The setting(s) that must be
changed for this application are noted in a list immediately below the
screenshot.
• COM port: chosen by Windows at the time the OPN is first
connected to Windows via USB (or COM1 if using RS232). See
Windows Device Manager under the heading 'Serial Ports (COM
& LPT)' for a list of such devices attached to your computer.
• Baudrate: 115200

Terminal IDs

When using the NetO-protocol with a multi-cradle, the use of terminal
IDs is mandatory to make sure that all files will be transferred without
conflicts and errors.
Since the OPN2002 does not have a system menu in which a terminal
ID can be configured, each OPN2002 has its own unique serial number
stored in non-volatile memory. This demo application uses this unique
serial number as the terminal ID. The serial number of OPN2002s is
printed on the back of the terminal, which makes it easy to add the serial
numbers in NetO32.
The six digit serial numbers of all your OPN2002s will have to added at
'Tools > Options > Polling and Timing > Terminals to Poll'.
When using the CRD2000, do not configure a Poll Speed faster than
0.5s because once an OPN2002 is communicating to the host, the other
OPN2002s will be temporarily muted for 250ms by the CRD2000 to avoid
data collisions. For this reason, an OPN2002 responds to a poll after a
random time ranging between 280ms and 480ms.
