Sonic Impact Technologies Larco USB Mat - Manual (Page 8)

Configuration: In-Range Detection Delay / Out-of-Range Detection Delay
The USB Mat has programmable delays that suppress the immediate sending of the locking sequence.
This is especially useful when using the USB Mat in a private office setting where you may leave the work
zone briefly and not want the system to lock. The maximum settable delay is 255 seconds. After this
delay time has elapsed, the programmable key sequences are invoked. The USB Mat has separate
delay to handle both the “In-Range” and “Out-of-Range” events. Adjust the delay by specifying the value
and clicking the “Apply” key. Adjust the settings to delays that work best for your work habits.
Important Note:
When using the USB Mat in a kiosk or standing workstation that have many users changing
logins, it is best to use the absolute shortest delay possible (i.e. zero). This will ensure the
computer will lock prior to the next user walking onto the mat.
Configuration: Walk-Away / Walk-To
As stated, the primary function of the USB Mat is to detect two events: when you walk away from the
computer and when you return. The most important of these two events occurs when you leave your
computer. During this event, the USB Mat can send to the computer a series of keystrokes that are
configured in the device. These keystrokes can be up to 4 characters with modifiers (ALT, CTL, Shift).
Click on the “Walk-Away” tab and you will see the screen below.
