If the Host does not supply sufficient power to the reader, a dialog box will appear on
the Host and the reader will be blocked (LED continues blinking). In this case,
disconnect the USB device cable at the Host (LED stops blinking), connect and
power-up an external supply to the USB device cable then
reconnect the USB device
cable to the Host and close the dialog box. The reader emits the beep OK signal.
You can now read codes. At this point you can read the USB interface configuration
code 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
site: http://www.scanning.datalogic.com.
The reader is ready.
