External Serial Altitude Encoder Support
Some locales may require the use of a certified altitude encoder with the Dynon SV-XPNDR-
261/262 Transponder. SkyView supports external serial altitude encoders that use
Icarus/Garmin format. When one is connected, the SV-XPNDR-261/262 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-261/262:

Wire a SkyView serial receive line to the respective serial transmit connection from the
serial altitude encoder. If you have more than one 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 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.
Non-Dynon 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 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 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 4-26.
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 11 and Table 12. SkyView will
function properly whether or not this altitude encoder functionality is used.
