ADL Vantage/ADL Vantage Pro/ADL Vantage 35
Although the radio modem supports both GMSK and 4FSK modulation, you cannot
select a modulation type with the user interface. The radio automatically selects
the appropriate modulation based on the channel bandwidth of the channel table
programmed into the radio (displayed on the Device Status screen as
CH BW: 12.5 or
25 kHz
), the data protocol, and the radio link rate. If you want to select a modulation
type first and then an appropriate channel bandwidth, protocol and link rate, use the
ADLCONF software to configure the radio.
Eight rarely changed functions are grouped together under Advanced Menus. In order
to speed everyday navigation, they are not displayed. The default values are indicated
in the table above. To make a change to any of these functions, go to the Advanced
Menus feature, press the down arrow until
Show
appears on the second line and
then press the
Enter
button. Press the right arrow sequentially to display these eight
functions. To hide these features, return to the Advanced Menus feature and then
select the Hide option.
Auto Rover Mode (Automatic Channel Selection)
The ADL Vantage radio (but not the ADL Vantage Pro/35) can automatically
select the channel with the strongest signal containing decipherable data, i.e.,
data configured with the same protocol, modulation and link rate. This allows
you to transmit data on one radio and then lock onto that transmission without
having to remember the channel number or frequency. However, both radios
must still be set to all other radio parameters (radio protocol, radio link rate,
etc.) in order to communicate.
To use the Auto Rover feature, scroll to the Channel/Freq screen on the ADL
Vantage front display. Go to the bottom of the channel table and press Enter
when you see one of the Auto Rover options. Select the Auto Rover 1 option
when you want the radio to automatically scan the entire channel table and
select the frequency with the strongest decodable signal. The Auto Rover 1
option will perform one scan when the radio is turned on, tune to the channel
with the strongest signal containing decipherable data and stop scanning.
The Auto Rover 2 option will perform a scan for the strongest decodable
signal when the radio is turned on and will perform a subsequent scan if the
percentage of received data packets drops under 90%.
If no decipherable data is detected on any of the programmed channels by
either of the Auto Rover options, the radio will continue to scan the channel
table. To stop the scan and select a channel temporarily (until the next
power cycle), wait until the channel is displayed on the LCD and press the
Enter button. Then check that the radio is configured in the same way as
the transmitter. After power cycling the ADL Vantage radio, it will return to
the selected Auto Rover option. To turn the option off, you must select the
MANUAL option on ADLCONF’s Radio Link screen, click Program and then
power-cycle the radio.
