baro adjustment to 29.92, its indicated altitude will match the altitude that is being reported to
your transponder.
Dynon SV-XPNDR-26X Transponder
If you are using a Dynon SV-XPNDR-26X Transponder, none of the above options need to be set
for the Dynon SV-XPNDR-26X module to receive pressure altitude. Instead, when the
Transponder is set up as described in the SV-XPNDR-26X Installation, Configuration, and Testing
section, it is automatically configured to receive pressure altitude from SkyView. Alternatively,
systems that require the use of an external altitude encoder can be configured per the
following section to have SkyView pass along an external pressure altitude source.
External Serial Altitude Encoder Support
Some locales may require the use of a certified altitude encoder with the Dynon SV-XPNDR-26X
Transponder. SkyView supports external serial altitude encoders that use Icarus/Garmin
format. When one is connected, the SV-XPNDR-26X 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-26X:
1. Wire a SkyView serial receive line to the respective serial transmit connection from the
serial altitude encoder. If you have multiple SkyView displays, the serial transmit wire
from the external serial altitude encoder should be connected to SkyView serial receive
wire to each display in parallel.
2. Ensure there is a shared ground between the D700/D1000 and the serial altitude
encoder.
3. Configure this serial port on each display under SETUP MENU > LOCAL DISPLAY SETUP >
SERIAL PORT SETUP. The SERIAL IN device for this serial port should be set to
ICARUS/GARMIN ALTITUDE.
Non-Dynon Transponder Serial Altitude Output Installation
To use SkyView‘s altitude output functionality with your transponder that can receive serial
altitude input:
1. Wire a SkyView serial transmit line to the respective receive connection on the
transponder. If you have multiple SkyView displays, a serial transmit wire from each
SkyView display should be connected to the external transponder in parallel.
2. Ensure there is a shared ground between the D700/D1000 and the transponder.
3. Configure the serial port on each display appropriately. There is an example serial port
configuration on 4-19.
Non-Dynon Transponder Serial Input Installation
SkyView can display the status of the Garmin GTX 327/330 transponders. To use this
functionality with SkyView:
