Using a Serial Joystick with the Vantage Lite.
Using a Serial Joystick
You must have a Y-adapter for a manual joystick. This plugs into the Switch A and B ports on the left side of your device case. The other end plugs into your joystick.
If you select Manual for your Selection Type, you may need to plug a third switch into the adapter in order to make a final selection.
Joystick Auto Scan
The scan proceeds automatically in the direction you moved your joystick.
Joystick Hold Scan
You must hold your joystick in the direction you want in order for the scan to proceed.
External Headpointer
You can plug an external USB headpointer into the USB port on the side of the case.
Mouse/Trackball/USB Joystick
Any of these options may be plugged into the USB ports on the right side of the device case.
Joystick Options
Auto Scan
Nudge your joystick. The device will automatically scan the overlay beginning in the direction you moved the joystick.
Hold
You must hold your switch to scan the overlay. Release it to stop the scan.
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 maintain contact with your switch 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.
Selection Type
Manual means you must activate your switch to make a selection. With a joystick, you may need to have a third switch plugged into the Y-adapter in order to make a selection.
Auto means your joystick and the device will automatically make selections you want.
Predictive Selection: This works hand-in-hand with Icon Prediction. (Icon Prediction is in the FEEDBACK MENUand 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. Your scan will go only to the highlighted keys.
Note: Icon Prediction will work whether Predictive Selection is On or not.
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.
Number of Rescans
Select the amount of times you want to scan the overlay.
