Per ATC/FAA requirements, SkyView’s serial encoder output reports pressure altitude, which,
by definition, is indicated altitude when the baro is set to 29.92. So, when you set SkyView‘s
baro adjustment to 29.92, its indicated altitude will match the altitude that is being reported to
your transponder.
Non-Dynon Transponder Serial Input Installation
SkyView can display the status of the Garmin GTX 327 and Garmin GTX 330 / 330ES
transponders. To use this functionality with SkyView:

Wire a serial receive line to the respective transmit line 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 under SETUP MENU > SYSTEM SETUP
> SERIAL PORT SETUP.

Configure the serial port on the transponder appropriately. For a Garmin GTX 327, 330 / ES,
the RS-232 output of the appropriate serial port on the transponder should be set to
REMOTE+TIS.
