Connecting the CF3680 to a Host
By default, the CF3680 is in USB PC Keyboard interface.
1. Connect a standard USB cable (standard USB-A to USB-B)
to the CF3680 and to the USB port on the host.
2. Power-up the host.
3. Verify that the CF3680 is on by presenting a bar code in
front of the scan window. The white LED should turn on and
read the bar code.
Note: The CF3680 does not beep to indicate a good read unless
this has been setup by the user with the user feedback pins.
See the CF3680 Installation Guide for more details
(available from your local Honeywell OEM representative).
