SV-XPNDR-26X Installation, Configuration, and Testing
SkyView System Installation Guide - Revision K 11-13
Exit SETUP. Repeat on any other displays on your SkyView system.
The data transmitted between the SkyView display and the SV-XPNDR-26X nominally includes
encoded altitude data from SkyView’s ADAHRS. Therefore, no other altitude encoder hardware
or SkyView serial port setup is required. However, 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.
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.
Transponder Settings
The aircraft tail number must be set in SETUP > SYSTEM SETUP > AIRCRAFT
INFORMATION > TAIL NUMBER prior to configuring the transponder.
The following settings need to be configured before testing and using the transponder. They
are all accessed under SETUP MENU > TRANSPONDER SETUP:
AIRCAFT HEX CODE: The Mode S Code is a 24 bit number issued to the aircraft by the
registration authority for the aircraft. Mode S codes for US-registered aircraft can be
found at the FAA aircraft registry at http://registry.faa.gov/aircraftinquiry/. These
addresses are usually written as a 6 digit hexadecimal number, although you may also
encounter one written as an 8 digit octal number (the FAA aircraft register only shows
octal number). SkyView only understands the hexadecimal format, so you must first
convert an octal number to hexadecimal. There is an Octal to Hexadecimal converter
tool available in the support section of http://www.trig-avionics.com/. Alternatively,
http://www.airframes.org provides hex codes for many countries’ aircraft that can be
directly inputted into SkyView. The hex code is the value shown in the ICA024 result
field.
The hex code needs to be set to the aircraft’s assigned code for the transponder to
function properly. The default code of 000000 is not a valid code. If the code is left
at 000000, the transponder will only work in SBY mode.
