SkyView HDX Display Installation and Configuration
4-28 SkyView HDX System Installation Manual - Revision E
• GPS devices provide GPS position and navigational information. These
devices are generally "moving maps" that depict airports, airspaces, etc., and
can generate flight plans. They provide source data for the moving map, HSI,
autopilot, synthetic vision, and the clock in the Top Bar. An example GPS
device is a Garmin X96.
• NAV devices provide radio-based navigational information from a VOR or ILS.
They provide source data for the HSI and autopilot. SkyView currently supports
the Garmin SL30 NAV Radio only.
• POS devices provide positional information only. These are generally simple
GPS receivers that cannot do flight planning. They provide source data for the
moving map, synthetic vision, and the clock in the Top Bar. Note that a POS
device does not provide any data for the HSI and will not appear in the HSI
NAVSRC rotation. An example of a POS device is the Dynon Avionics SV-
GPS-2020.
4.4.2.3 Input Function Considerations and Priorities
SkyView’s Moving Map Page uses POS and GPS sources for its data. Regardless of the
number of data sources in your system, this page prioritizes these sources and fails over
to them as follows:
POS 1 GPS 1GPS 2GPS 3GPS 4POS 2POS 3POS 4
For example, if your system has one (1) SV-GPS-2020 configured as POS 1 and a
Garmin 396 configured as GPS 1, the Moving Map will always use the SV-GPS-2020 as
its primary data source. If the SV-GPS-2020 fails or you configure its input function to
NONE, the Moving Map Page will use the Garmin 396 (or other GPS source) configured
as GPS 1 as its primary data source.
The SkyView HSI uses GPS and NAV sources for its overlays and the user must choose
the source during operation.
SkyView’s internal Navigation Mapping System can generate navigation
information which can be displayed on the HSI. The Navigation Mapping
System requires GPS data, which is sourced from the active (highest priority
in the above list) POS or GPS source. Regardless of what source is being
used for position information, the navigation provided by the Navigation
Mapping System is always the SKYVIEW source on the HSI.
4.4.2.4 Baud Rate
Set this to match the baud rate of the serial device that is connected to the serial port.
SkyView supports the following baud rates: 1200, 2400, 4800, 9600, 19200, 38400,
57600, and 115,200.
Note that if you use a serial port for a split function (e.g., GPS in and altitude encoder
out), the input and output devices must use the same baud rate.
