USB INTERFACE CONFIGURATION 
 
The USB interface is compatible with: 
Windows 98 (and later)  IBM POS for Windows 
Mac OS 8.0 (and later)  4690 Operating System 
 
 
START-UP 
As with all USB devices, upon connection, the Host performs 
several checks by communicating with the Gryphon™. During 
this phase the green LED on the Gryphon™ reader blinks and 
normal operations are suspended. Two basic conditions must 
be met before Gryphon™ is ready to read codes, the correct 
USB driver must be loaded and sufficient power must be 
supplied to the reader. 
 
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). 
 
If the Host supplies sufficient power to the reader, the start-up 
phase ends correctly, the green LED stops blinking and the 
reader emits the beep OK signal. 
 
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 (green LED continues blinking). In this case, 
disconnect the USB cable at the Host
 (green LED stops 
blinking), connect and power-up an external supply to USB 
cable then
 reconnect the USB 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.datalogic.com
. 
 
The reader is ready.
