Acceptance Time

The amount of time you must hold your switch down before the button you have scanned to is accepted. For example, if you set acceptance time for .50 seconds, you must activate and hold your switch for ½ second before the key will be selected.

Release Time

This determines how long to wait after the switch is released before it will accept another activation with the same button or switch. For example, if you set the Release Time for 1 second, you must wait one second after you release the switch before you can continue to scan or activate your switch. If you release your switch and then accidentally activate it again before the release time has passed, your device will not activate.  This feature helps eliminate inadvertent double hits.

Scanning Speed

This is the amount of time it takes for your device to move from one button, row, or column to the next in a scan.  The default scanning speed is one second. This means it takes one second from the time one key is highlighted until the next key is highlighted.

Number of Rescans

Select the number of times you want your device to automatically scan the page.  The default is 3 times then the scan will stop until a switch is activated again.

Initial Delays

Initial delays happen after the switch activation starts the scan but before the area defined.  If an initial delay is set for Rows, prior to the system starting the scan of rows, the system will delay the set amount.

Activation Delay

This gives a chance to change your mind when you have selected a button. This is automatically set to your Scanning Speed.  For example, let's say your scanning speed is set to one second (1.0). You scan to and select a button, then realize it's not the button you want. You have one second to activate your switch again to "de-select" the button and then scan to a new button.
