How do I Use a Joystick with the SpringBoard Lite?
NOTE: The Joystick option is available only with the 32/36 location overlays.
You must have an adapter to use a joystick with the SpringBoard Lite.
A joystick is the most versatile scanning device because you can push it in any direction to scan to the key you want.
You will need an adapter that will allow you to connect to both the A and B switch connectors on the SpringBoard Lite as well as an option to connect a third switch for manual entry. The other end of your adapter must fit the connector on your joystick.

Scanning Speed
This is the amount of time it takes for your device to move from one key, 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.
Acceptance Time
The amount of time you must hold your switch down before the key you have scanned to is accepted. The device beeps when your key 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 and the device beeps.
Release Time
This tells your device how long to wait after you release your switch before you can make another activation with the same key or switch. For example, if you set the Release Time for 1 second, you must wait one second after you release your 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 make any activations.
Auto Repeat
This lets you choose how fast a key will repeat when you hold it down.
Predictive Selection (not available on single hit overlays)
Note: Predictive Selection and Icon Prediction are only available when you are using an overlay that requires two or more hits to bring up a message. None of the default SpringBoard overlays contain icon sequences. All vocabulary can be reached with a single hit. This works hand-in-hand with Icon Prediction. (Icon Prediction is in the FEEDBACK MENU and the default is ON.) When you turn Predictive Selection On, your device highlights only those icons where messages are stored. These highlighted icons are the only keys on the keyboard that will produce a response.
You can change the color of the non-active keys to grey or white. Go to the FEEDBACK
MENU, Icon Prediction and select Grey or White. Grey allows you to see the shadow of the icon on the key; white turns the entire key white so it looks blank. But if you try to select a grey or white key, nothing will happen.
Note: Icon Prediction alone allows you to press grey or white keys. The key's icon will appear in the Icon display area but no message will be spoken. Icon Prediction will work whether Predictive Selection is On or not.
Note: Remember that these two options are only available when you are using an overlay
with icon sequences.
Scan Type: Auto or Hold
Auto Scan
Your device automatically scans the keyboard.
Hold Scan
You must press and hold your switch to scan the keyboard.
Activation Delay
This gives you a few seconds to change your mind when you have selected a key. 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 key, then realize it's not the key you want. You have one second to activate your switch again to "de-select" the key and then scan to a new key.
Selection Type: AUTO/MANUAL
If you select Manual, you must have a third switch plugged into your device. You will use this switch to make your final selection. If you select Auto, your device will automatically select the key you have scanned to after the Acceptance Time has passed.
Number of Rescans
Select the number of times you want your device to automatically scan the overlay. The default is 3 times, then the scan will stop until you activate a switch to start it again.
