USB Configuration
The USB interface is available for BC-80x0 and C-8000 devices and is compatible with the
following Operating Systems:
Windows 98 (and later) IBM POS for Windows
Mac OS 8.0 (and later) 4690 Operating System
USB Start-up
As with all USB devices, upon connection, the Host performs several checks by
communicating with the device. During this phase normal operations are suspended. Two
basic conditions must be met before the device is ready, the correct USB driver must be
loaded and sufficient power must be supplied to the reader.
1. For all systems, the correct USB driver for the default
USB-KBD interface is included in
the Host Operating
System and will either be loaded automatically or will be
suggested by the O.S. and should therefore be selected
from the dialog box (the first time only).

Normally the Host supplies sufficient power to the
device and the start-up phase ends correctly. (The
reader's LED stops blinking and the reader emits the
beep OK signal).
In rare cases, if the Host does not supply sufficient
power to the
device, a dialog box will appear on the Host
and the device will be blocked (the reader's LED
continues blinking). In this case, disconnect the USB
device cable
at the Host (the reader's LED stops
blinking), and then try a different USB port as indicated
by the Operating System message. (The device emits the
beep OK signal. You can now read codes).
2. At this point you can read the USB interface configuration cod
e according to your
application. Load drivers from the O.S. (if requested). When configuring the USB-COM
interface, the relevant files and drivers must be installed from the USB Device Installation
software, which can be downloaded from the web page
http://www.scanning.datalogic.com
.
The device is ready. Successive start-ups will automatically recogn
ize the previously loaded
drivers.
