Instant Update Utility

Occasionally, newer versions of the modem's internal software may be made available to reflect advances in the rapidly-changing ADSL field. This software will be made available from 3Com and may be downloaded to your PC using this Dual Link utility. Once the new software is stored on your PC, use the Manager to update the Dual Link modem

Installing Instant Update

The Instant Update package allows you to automatically obtain software updates for your modem over the Internet. To install it from your Install CD, click on Start>Programs>3Com Dual Link Modem >Advanced>Install Instant Update

This will start the install procedure. Ensure your CD is in your CD-ROM drive. Then click OK.

You will be asked to accept or choose the destination directory.

And given the opportunity to change the program folder name.

Click Finish to complete the setup of the utility.

 

Configuring the Instant Update Utility

There is one last step that you will want to complete in order to have full control over the Utility. From the Start button, select Start>Programs>Instant Update>Instant Update Configuration.

This gives you a series of screens that allow you to control the operation and frequency of the Instant Update. By default, the Instant Update will check for code updates from the 3Com web site every 30 days.

You may not wish to change the defaults. On the scheduling tab, if you think there may be an updated file available, you can select Update Now. Click Close to exit the Instant Update configuration screen.

 

Updating your modem software

Once the Instant Update Utility has been installed on your PC, it will monitor the Internet for updates to the basic operating software (called a .nac file) for your Dual Link Modem and download an update file when one is found. This file will be downloaded to your PC and stored in a folder on your hard drive. By default, the file location is: C:\Program Files\3Com\Dlcc\Update. You can then download it to your Dual Link at your convenience.

To retrieve a downloaded .nac file and install it on your Dual Link, first open your Dual Link Modem Settings Screen.

From the Main page, select System.

Under the category System Maintenance, click on Upgrade Software.

Browse to find the location of the .nac file on your hard drive. By default, the file is usually stored in C:\Program Files\3Com\Dlcc\Update. Then click Download Software. After starting the download, remain on the screen until the download completes (about one minute).

Serial download

This is not the preferred method, but we've documented it here in case you need to use it. This procedure requires that you first connect your Dual Link unit to a Com port on your PC using a DB-9 to DB-9 cable.

Once this is done, click Start>Programs>3Com Dual Link Modem>Advanced>Serial Download to start the serial download. You will see the following screen.

You will be asked to input the Com port and baud rate. Once you click OK, an instruction screen will open up, similar to that shown here.

It will direct you to:

  1. Turn OFF (unplug) the Dual Link unit.
  2. Press Return to start the download.
  3. Turn on the Dual Link unit.

This will write the new .nac file onto the Dual Link.
