Sonic Impact Technologies Larco USB Mat - Manual (Page 9)

In the above screen shot, the unit has been configured to send the CTL-ALTDEL+K+Backspace key
sequence. This key sequence is used to lock Windows 2000 workstations.
Note: The USB Mat units are shipped from the factory, without any keystrokes programmed into
the device and therefore will not lock your computer until you configure the keystrokes.
You will need to configure the USB Mat for the keystrokes you currently use to lock your computer. If
you click on the “Misc” folder, there are some quick settings that will help get Windows 2000 and
Windows XP users quickly configured with the most common settings for these operating systems.

By selecting the Win2K option the USB Mat will be set with:
Walk-Away: CTL-ALT-DEL+K+Backspace+Escape 2
Walk-To: CTL-ALT-DEL
2
The Backspace and Escape characters are sent to clear any entries made if the user does not log into the password dialog box
prior to leaving the proximity.
