If you cannot get your USB to serial adapter to work, please check the
following:
1. Check the communications window of DriveWizard
™ for the proper
settings (Figure 4.27).
2. Check that the adapter is installed correctly by checking Windows
Device Manager (Figure 4.28).
3. Check that the drivers for the adapter are the latest and the proper ones
for your Windows operating system.
4. Check that another program has not captured the USB to serial adapter
such as Palm Pilot Hot Sync or a DDE server from a data acquisition
program.
5. Sometimes re-booting your PC after installing the USB to serial adapter
will force Windows to enable the device.
