HopNet Configuration Wizard (HNWizard)

Open the Wizard by double-clicking on the icon on the desktop. When the Wizard
boots up, it will automatically detect the serial port to which the HopNet radio is
connected and its baud rate. This process takes a few seconds to complete. During
this process, the “Please wait” screen is displayed. Once the radio has been found and
the Baudrate determined, the “Finished” screen is displayed. Click on the Continue
button to enter the Wizard.

NOTE: HNWizard is used with a variety of Cirronet radios. Not all radios support
all the functions and features of every Cirronet radio. Thus, some selections in the
Wizard will be grayed out if they are not applicable to the radio in use.

After detecting the serial port and baud rate of the HopNet radio, the Wizard reads the
settings of the HopNet radio that is connected to the PC and will display them in the
various parameter windows. In the bottom left corner of the Wizard window, the
Base/Remote status, the serial number and the communication port are always
displayed.

NOTE: The S/N displayed in the bottom left corner is the serial number of the
radio inside the unit and is different from the serial number of the HopNet unit.
Both the HopNet unit serial number and the radio serial number are on the radio
unit of the HopNet product. The Wizard will also prompt to save the configuration
settings to a file.
