in electronics stores and over the Internet. We have tested 2 adapters that are commonly
available and they function 100% with DriveWizard

™:

(a) Dynex P/N DX-UBD9 available at Best Buy stores
(b) Radio Shack P/N 26-183 available at Radio Shack Stores

The USB to serial adapter always comes with a CD of the drivers required to

properly operate the adapter on your particular operating system. Follow the installation
instructions provided with the adapter. It would be a very good idea to go to the
manufacturer’s website to check for the latest driver’s for your operating system.

When the adapter is successfully installed, it will appear in the Windows Device

Manager as another serial port. Refer to Figure 4.27 for how the Dynex adapter appears.
The adapter appears under the PORTS (COM & LPT). In Figure 4.28 you can see that it
is assigned to COM 5. Therefore, to use this device in DriveWizard

™ you would select

COM 5 on the Communications setting window (Figure 4.27).

RS232C through USB Adapter: This method is becoming more popular as newer PC’s
do not have a hardware serial port but only USB serial ports. DriveWizard

the same as a PC hardware RS232C port so that DriveWizard

™ does not know

the difference between a USB to serial adapter or a PC hardware port. The USB to serial
adapter will be assigned a new PC COM port number (usually above 4) when it is
installed in the PC.
