Transferring Files to and from Handhelds

You can send documents, Operating System (OS) files, and folders to another TI-Nspire™ handheld.

Rules for Transferring Files and Folders

• You can transfer documents and OS files.
• Operating systems are not interchangeable between different handheld types. For example, you cannot transfer a CAS operating system to a non-CAS handheld.
• If a document with the same name as the one you are sending already exists on the receiving handheld, the document will be renamed. The system appends a number to the name to make it unique. For example, if Mydata existed on the receiving handheld, it would be renamed Mydata(2).

Both the sending and receiving handhelds will display a message that shows the new name.

- There is a 255-character maximum length for a file name, including the entire path. If a transmitted file has the same name as an existing file on the receiving handheld and the file names contain 255 characters, the name of the transmitted file will be truncated to enable the software to follow the renaming scheme described in the previous paragraph.

- All variables associated with the document being transmitted are transferred with the document.

• Transmissions will time out after 30 seconds.

Caution: Some older TI-Nspire™ handhelds cannot receive folders; only files. If you receive an error in sending to an older TI-Nspire™ handheld, see Common error and notification messages.

Updating the Handheld Operating System

To take advantage of the latest handheld features and updates, download the latest operating system files from the Education Technology website (education.ti.com). You can update the operating system (OS) on TI-Nspire™ handhelds using a computer and the following software:

• TI-Nspire™ Teacher Software
• TI-Nspire™ Student Software
• TI-Nspire™ CAS Teacher Software
• TI-Nspire™ CAS Student Software
- TI-Nspire™ Teacher Navigator™ Software

- TI-Nspire™ CAS Teacher Navigator™ Software

In the classroom, you can use the TI-Nspire™ Docking Stations to upgrade the OS on multiple handhelds at the same time.

You can also transfer the OS from one TI-Nspire™ handheld to another or from one TI-Nspire™ CX handheld to another. However, handheld operating systems are not interchangeable. You cannot transfer a CAS operating system to a non-CAS handheld and you cannot transfer a TI-Nspire™ handheld operating system to a TI-Nspire™ CX handheld.

What You Need to Know

• If there is not enough room on the receiving handheld for the upgrade, a message is displayed. For more information, See Memory and File Management.
• OS upgrade operations do not delete user documents. The only time documents are affected by an OS installation is if the receiving handheld has a corrupted OS. In this situation, documents may be affected by OS restoration. It is a good practice to back up important documents and folders before installing an updated operating system.

Warning: Upgrading the operating system will delete all TI-84 applications and files. Before installing an OS upgrade, you should use TI Connect to back up all TI-84 applications and files to a computer. You can copy them back to the handheld when the OS upgrade is complete.

Before You Begin

Before beginning an OS download, ensure that batteries are at least 25 percent charged.

• To check the status of the rechargeable battery in TI-Nspire™ CX handhelds, press 📋 on 5 4 to open the Handheld Status dialog box.
• To check the status of both the rechargeable battery and the AAA batteries in TI-Nspire™ handhelds, press 📷 on 5 4 to open the Handheld Status dialog box.

When in OS download mode, the Automatic Power Down ^™ (APD ^™ ) feature does not function. If you leave your handheld in download mode for an extended time before you begin the downloading process, your batteries may become depleted. You will then need to replace or recharge the batteries before downloading the OS.

Finding Operating System Updates

For up-to-date information about available OS upgrades, check the Texas Instruments website at education.ti.com.

You can download an OS upgrade from the Texas Instruments website to a computer, and use a USB cable to install the OS on your TI-Nspire™ handheld. You will need an Internet connection and the appropriate USB cable to download the updates.

- If Yes is not selected within 30 seconds, the handheld automatically responds with No, and the transmission is cancelled.

- It is important to save and close all open documents before performing an OS Upgrade. Continuing with an OS Upgrade on a handheld with an open, unsaved document will cause the loss of that data.

1. While the upgrade is in progress, the following messages are displayed on the receiving and sending handhelds:

2. "Receiving OS. Do not unplug cable."

3. " Sending OS. Do not unplug cable."

4. After the transfer completes, the sending handheld receives a completion message and you can unhook the cable. The OS is automatically installed on the receiving handheld. During the installation process, the "Installing OS " message is displayed on the receiving handheld.

5. When the installation is complete, the "OS has been installed. Handheld will now restart." message is displayed. The restart is initiated. If the sending handheld is still attached to the cable, the successful transmission message remains displayed on that handheld's screen.

Important:

• For each receiving handheld, remember to back up information as necessary and install new batteries.
• Be sure the sending handheld is on the Send OS screen.
