4.3.9.5 External Serial Altitude Encoder Support
Some locales may require the use of a certified altitude encoder with the Dynon Avionics
SV-XPNDR-261 Transponder. SkyView supports external serial altitude encoders that
use Icarus/Garmin format. When one (1) is connected, the SV-XPNDR-261 uses the
external altitude encoder data source instead of SkyView’s own ADAHRS-generated
pressure altitude. However, the altitude displayed by SkyView on the PFD page is
ALWAYS sourced from SkyView ADAHRS data.
To have SkyView use an external altitude serial encoder as the pressure altitude source
for the SV-XPNDR-261:
• Wire a SkyView serial receive line to the respective serial transmit connection
from the serial altitude encoder. If you have more than one (1) SkyView display,
make the same connection to all SkyView displays.
• Ensure there is a shared ground between the SkyView display and the serial
altitude encoder. If you have more than one (1) SkyView display, make the
same connection to all SkyView displays.
• Configure this serial port on each display under SETUP MENU > SYSTEM
SETUP > SERIAL PORT SETUP. The SERIAL IN device for this serial port
should be set to ICARUS/GARMIN ALTITUDE.
4.3.9.6 Non-Dynon Avionics Transponder Serial Altitude Encoder Output
To use SkyView’s altitude output functionality with your transponder that can receive
serial altitude input:
• Wire a SkyView serial transmit line to the respective receive connection on the
transponder. If you have more than one (1) SkyView display, make the same
connection to all SkyView displays.
• Ensure there is a shared ground between the SkyView display and the
transponder. If you have more than one (1) SkyView display, make the same
connection to all SkyView displays.
• Configure the serial port on each display appropriately. There is an example
serial port configuration on Page 4-29.
4.3.9.7 SkyView Altitude Encoder Output Formats
There must be a SkyView ADAHRS installed for the altitude encoder output
to function.
SkyView outputs its altitude measurements in two different formats. You can use either
format on any of the serial ports. These formats are described in Table 10: Icarus Format.
