If you have a Vantage with the serial number of 2500VT or higher and with 4.0 software you can connect a USB cable to your communication aid and your computer, then use your communication aid to work on your computer.
If you have a Vanguard with the serial number of 2100VG or higher and with 4.0 software you can connect a USB cable to your communication aid and your computer, then use your communication aid to work on your computer.
You received a USB cable in the box with your device. If this cable has been lost, you can purchase a replacement cable at a local computer access store. This cable is called a USB to A TO B cable or a USB Printer cable.
Connecting the USB Cable
Turn OFF your device and shut down your computer. Both devices should be OFF.
Find the USB cable that came with your device.
Connect the A TO B of the cable (in this instance, this is the end with the small square connector) to the square port on side of your device.
Connect the USB end of the cable to the USB port on your computer (this may be on the front of the computer or in back, or both).
Turn your computer and your device back ON.
Now you will want to adjust some settings so your device will send data through the USB port to your computer.
1. Select your TOOLBOX key on the top of your device.
2. In the Toolbox, open the OUTPUT MENU.
3. Set Output Method to USB Disk.
4. Set Output to ON
5. Auto Line Feed and Character Pacing should be set to OFF.
6. If you plan to send large amounts of text at one time, such as a Notebook, Character Pacing should be turned ON.
7. Output Mode should be set to Immediate.
8. The Keyboard Layout is default to US
9. Select OK to exit
Now open a word document on you computer and try it out. What you type on the Vantage/Vanguard should appear in the word document.
