KNOWN LIMITATIONS

   Installation/User Interface:

      You must follow the procedure outlined in the "DRIVER INSTALLATION NOTES
      FOR WINDOWS 2000" section of this document to properly install the
      driver set.

      Within the wizard mode, if invalid input has been entered and back
      button is pressed, an error message may appear indicating that
      the input is invalid.  A valid input needs to be entered to be able
      to go back.

   PortAssist Viewer:

      PortAssist Viewer is the diagnostics application used to troubleshoot problems
      on your wan connections.  There is no Start menu link to run PortAssist Viewer.
      Select "Start|Run" and type "Digiview".

   RAS Adapters:

      On Channelized T1 Wink Start Trunks without dial tone supervision,
      modems must be initialized with ATX3 for dial out.

      When configuring dial up modem service for a line, all modems on the
      line should be configured since incoming calls may be assigned to any
      channel.

      On ISDN Trunks, the following rules are applied to modem dial strings:
          a) A comma (delay) in the first or second position is allowed.
          b) then the first non-numeric character terminates the dial
             string (e.g. 9,12345678 is a valid dial string and
             9,1,234-5678 is not).


DRIVER INSTALLATION NOTES FOR WINDOWS 2000

   Note: Update Driver functionality is not currently supported.  If you have
   already installed drivers for your adapter, you must uninstall them first.
   Otherwise, skip to step 2.

   1. Uninstall previously installed drivers.  From "Control Panel" run 
   "Add/Remove Hardware" wizard.  Follow instructions to "Uninstall" your 
   Digi DataFire adapter(s).

   2. Run the program DgClean.cmd to remove existing INF files for your 
   adapter.  This will ensure the new drivers will be installed correctly.  
   Dgclean.cmd is located in the folder with your downloaded drivers.

   3. Shutdown your computer and install the adapter according to the 
   "Hardware Installation Instructions" included with the adapter.
   
   4. Start your computer and login.  When the "Found New Hardware Wizard"
   appears, follow instructions to "Search for a suitable driver for my 
   device".  Specify the folder in which you downloaded the driver.
   
   5. Windows will display a "Digital Signature Not Found" message, explaining
   that the drivers are not signed.  Click "Yes" to continue the installation.
   You will see several of these warnings,  click "Yes" to continue through all
   of them.
   
   6. Follow instructions to complete the installation.
