SSID of Wi-Fi UDP NMEA or GDL90 data server (Access Point).
Typically, the "server" is one of SoftRF Editions. But other sources, such as Stratux or similar equipment, should also suffice.

Wi-Fi key to access this server.

     metric    - display and say information in metric system of measurement ;
     imperial - display and say information in imperial system of measurement ;
     mixed     - almost the same as metric, but all the altitudes are in feet .

An option to choose from two different display views.
Depending on your SkyView hardware, you can change the view in runtime by pressing MODE button.
If your hardware does not have the control button - this view is fixed throughout entire session.

     radar   - radar-alike view. "Scale" navbox gives a value of full span ;
     text     - plain text representation of traffic information .

     CoG Up    - your aircraft's course over the ground is up ;
     North Up - GNSS North is up .

Initial value of radar view's zoom level (scale factor).
Depending on your SkyView hardware, you can change the zoom level in runtime by using UP and DOWN buttons.
If your hardware does not have the control buttons - this zoon level is fixed throughout entire session.

Your preferable database for decoding unique aircraft's ID code.
This option makes sense only when you've inserted proper memory card in SkyView's micro SD slot.

     auto          - selection is to be made based upon aircraft's NMEA "ID type" value (when available) .
     FlarmNet
     GliderNet
     PilotAware

When an aircraft's record will be found, "Text view" will show text identification of this aircraft.
You can choose what particular field of the record will be displayed there.
If no any records found - hexadecimal ID value will be shown.

     registration      - registration number of this aircraft ;
     tail/CN             - tail / competition number (when available) ;
     make & model - make and model of the aircraft (when available) .

     off       - no voice traffic alerts ;
     voice 1 - Male voice ;
     voice 2 - Female voice ;
     voice 3 - Female voice (allegro) .

Periodic full e-Paper screen refresh. Typically takes 1-2 seconds.
It helps to remove residual traces of previous information, so-called 'ghosts'.
'Ghosts' are known to be temperature and UV dependent.

     off                - do not apply this full screen refresh ;
     2 minutes    - enforce full screen refresh every 2 minutes (counter against heavy 'ghosting' effect);
     5 minutes    - enforce full screen refresh every 5 minutes ;
     10 minutes   - enforce full screen refresh every 10 minutes (little or no 'ghosting') .
