[SECTION 1: Driver Overview]

[SECTION 2: Devices Supported]

The FreedomUSB product line benefitted from changes in its manufacturing
processes in March 2003.  This driver set supports only units manufactured
since the changes were implemented.  Prior units are supported by a different
driver set.

All FreedomUSB products have a sticker listing manufacturing data.  This
sticker is on the bottom of the case, except for the SSU devices, which
have the sticker on the side of the case.

Find the sticker on your FreedomUSB product.  Locate the assembly revision
level.  The assembly revision level is made up of a letter designating a
major level and an optional digit designating a minor level.  Major revisions
increase in alphabetical order.  Minor revisions increase in numerical order.

  Example:  F3 is higher than F2.
            F2 is higher than F.
            F  is higher than E4.

The following Quatech FreedomUSB products are supported by this driver set:

   Model          Supported revisions      Description
   -----          -------------------      -----------
   SSU-100          C3 and later           Single-channel USB to RS-232
   DSU-100          F3 and later           Two-channel USB to RS-232
   DSU-200/300      F3 and later           Two-channel USB to RS-422/485
   QSU-100          F3 and later           Four-channel USB to RS-232
   QSU-200/300      F3 and later           Four-channel USB to RS-422/485

    "Settings->Control Panel."  Double-click the "System" icon.  Click on
    the "Hardware" tab, then the "Device Manager" button.
3.  Double-click on "Multi-port serial adapters."  You should see your

    with the file highlighted.
13. Select all of the files that matched the search results.  (The search
    results window should still be open if you need to refer back to it.)
    Also select the files with the same name but a file extension of .PNF.
    For instance, if the search found OEM7.INF, select OEM7.INF and OEM7.PNF.

15. Close all windows.
16. Shutdown the computer and reboot.

Installing the new drivers
