  1. INTRODUCTION

     This document describes the device driver that supports
     the Digi devices listed below. The driver is for use
     in the Microsoft Windows 2000 and Windows XP environments.

     Refer to the following number when searching the Digi
     International Inc. Web site (www.digi.com) or the FTP
     site (ftp.digi.com) for the latest software package:

     40002253_<highest revision letter>


  2. SUPPORTED PRODUCTS

     Digi DataFire SYNC 2000 2P Adapter
     Digi DataFire SYNC 2000 4P Adapter
     Digi DataFire Sync/570i 2P PCI Adapter
     Digi DataFire Sync/570i 4P PCI Adapter


  3. KNOWN LIMITATIONS

     When configuring an adapter using the configuration wizard, if
     invalid input is entered and the back button is pressed, an
     error message might appear indicating that the input is
     invalid. Enter valid input before pressing the back button to
     suppress this warning and to back up the wizard.

     For PPP links, both sides of a connection must disconnect
     before they can be reconnected.

     When using the SDLC interface, the maximum BTU (Basic
     Transmission Unit) is limited to 521 bytes. This is a known
     limitation of the IBM SDLC link service provided in SNA
     Server. See the Microsoft SNA article, "Maximum BTU Limit for
     Dumb SDLC Interface," for more information.


  4. DRIVER UPDATE

     WINDOWS 2000
     ------------

     To update a previously-installed device driver to a new
     driver, follow these steps.

     a. First, run the program dgarcln.cmd to move the existing INF
        files for the adapter. This ensures that the new driver
        files will be installed instead of the old driver files.
        Dgarcln.cmd is part of the driver software package and can
        be found in the same directory as the new driver files.

     b. Next, navigate to the Device Manager and locate the device
        whose device driver is to be updated:

          o From the Desktop, right-click on "My Computer"
          o Select "Manage"
          o In the left-hand side of the Computer Management
            window, select "Device Manager"

        Locate the adapter to update:

          o In the right-hand side of the window, expand the
            device category entitled: "Network adapters"
          o Right-click on the device to update
          o Choose "Properties"

        Begin the upgrade process:

          o Click the "Driver" tab
          o Click the "Update Driver..." button
          o Click "Next >"
          o Verify that the default option is selected, "Search for
            a suitable driver for my device (recommended)"
          o Click "Next >"
          o Deselect all options
          o Select the option, "Specify a location"
          o Click "Next >"
          o Enter the path to the new driver files and click "OK"
          o Click "Next >"

     c. Windows will display a "Digital Signature Not Found"
        message, explaining that the driver is not signed.  Click
        "Yes" to continue the installation. You may see several of
        these warnings -- simply click "Yes" for each message to
        proceed with the upgrade.

     d. Windows will now install the new device driver for the
        adapter and its modems.

     e. Follow any other instructions to complete the installation.

     f. Click "Finish" to dismiss the Upgrade Device Driver Wizard.

     g. Repeat steps b. through f. for each device to be upgraded.

     WINDOWS XP
     ----------

     The Windows XP upgrade process is very similar to the Windows
     2000 upgrade process.

     a. First, run the program dgarcln.cmd to move the existing INF
        files for the adapter. This ensures that the new driver
        files will be installed instead of the old driver files.
        Dgarcln.cmd is part of the driver software package and can
        be found in the same directory as the new driver files.

     b. Next, navigate to the Device Manager and locate the device
        whose device driver is to be updated:

          o Open the Start menu
          o Right-click "My Computer"
          o Select "Manage"
          o In the left-hand side of the Computer Management
            window, select "Device Manager"

        Locate the adapter to update:

          o In the right-hand side of the window, expand the
            device category entitled: "Network adapters"
          o Right-click on the device to update
          o Choose "Properties"

        Begin the upgrade process:

          o Click the "Driver" tab
          o Click the "Update Driver..." button
          o Click "Next >"
          o Verify that the default option is selected, "Search for
            a suitable driver for my device (recommended)"
          o Click "Next >"
          o Deselect all options
          o Select the option, "Specify a location"
          o Click "Next >"
          o Enter the path to the new driver files and click "OK"
          o Click "Next >"

     c. Windows will display a dialog indicating that the
        software has not passed Windows Logo testing. Choose
        "Continue Anyway" to proceed with the upgrade. You
        may see several of these warnings -- click "Continue
        Anyway" for each message to continue the installation.

     d. Windows will now install the new device driver for the
        adapter and its modems.

     e. Follow any other instructions to complete the installation.

     f. Click "Finish" to dismiss the Upgrade Device Driver Wizard.

     g. Repeat steps b. through f. for each device to be upgraded.
