2. Plug the proper end of the USB cable into the PC and the other end into the DGC-2020.
3. The Found New Hardware Wizard dialog box pops up.
4. Select “No, not this time” and select Next to continue.
5. Choose to “Install from a list or specific location (Advanced)” and select Next to continue.
6. Insert the CD-ROM labeled BESTCOMSPlus into the PC CD-ROM drive.
7. Browse to the \driver folder on the CD-ROM and select Next to continue.
When installation of the driver is complete, you may be asked to restart your computer.
Establishing Communication
Communication between BESTCOMSPlus and the DGC-2020 is established by clicking on the Connect
button on the Connection screen (see
Figure 4-6) or by clicking on the C
onnect button on the lower menu
bar of the main BESTCOMSPlus screen (Figure 4-1). If you receive an “Unable to Connect to Device”

BESTCOMSPlus memory. See
