SV-XPNDR-26X Installation, Configuration, and Testing• SIL: 0 (Unknown integrity)NACp: 8, 9 or 10. Dynamic, as reported by GPS.NIC: 8 (Containment radius LOCALDISPLAY SETUP > SERIAL PORT, this option will be unavailable: The SV-ADSB-470automatically receives ADS-B In traffic and weather via the UAT frequency band.Note that the options in the ADS-B IN FREQUENCY only have an effect withtransponder software 2.02 or above. See the Transponder Software Updatessection below for more information about transponder software.o NONE: The aircraft does not have ADS-B In capabilityo 978 MHz UAT: The aircraft can receive ADS-B traffic and/or weather informationvia a non-Dynon UAT band (978 Mhz) device.o 1090 MHz ES: The aircraft can receive ADS-B traffic information via a 1090 MhzES (extended squitter) device.Altitude Encoder CalibrationIn most transponder systems, a calibration is normally carried out every 24 months, as part ofthe altimeter checks on the aircraft. The maximum allowed difference between the primaryaltimeter and the altitude encoder is 125 feet in ETSO C88a and TSO C88b. The primaryaltimeter in SkyView and the altitude encoder are one and the same device. It is thereforeimpossible for the encoder and the primary altimeter to exceed 125 feet of altitude difference.They will always be exactly the same as each other, thereby meeting the TSO requirements.Therefore, no altitude encoder calibration is possible or necessary.At times it may be useful to know the altitude that is being reported to the transponder. SinceSkyView sends pressure altitude to the SV-XPNDR-26X, setting BARO to 29.92 will display thepressure altitude being transmitted to the transponder in the normal SkyView altitude displayon the right side of the PFD page.However, do note that there is a single point altitude adjustment, located in SETUP MENU >HARDWARE CALIBRATION > ADAHRS CALIBRATION > ALTITUDE ADJUST that adjusts SkyView’sbarometric altimeter. This adjustment affects both the displayed altitude and the encodedaltitude that is sent to other devices.11-18 SkyView System Installation Guide - Revision O
