11. SV-XPNDR-26X Installation, Configuration, and TestingThe SV-XPNDR-26X Mode S transponder models are DO-181D compliant Mode S level 2elsdatalink transponders, with support for ADS-B extended squitter, which also meets the relevantenvironmental requirements of DO-160F/ED-14F. The SV-XPNDR-262 has a nominal poweroutput of 125 Watts, and meets the power output requirements for Class 2. The SV-XPNDR-261has a nominal power output of 250 watts, and meets the power output requirements for Class1. The ADS-B function meets DO-260A class B0. The SV-XPNDR-26X is certified to ETSO 2C112band ETSO C166a, and to FAA TSO C112c and C166a.There are two transponder modules offered by Dynon Avionics. The SV-XPNDR-262 is a Class 2transponder that is limited to use beneath 15,000 feet and under 175 knots. The SV-XPNDR-261is a Class 1 transponder that can be used above those limitations. Throughout this manual, theyare often referred to together as the SV-XPNDR-26X for instructions that apply to both versions.The SV-XPNDR-26X transponder is controlled using SkyView’s on-screen menu system. Thisallows the transponder to be mounted separately from the instrument panel and reduces theamount of panel space taken by the transponder. SkyView also provides pressure altitudedirectly to the transponder, eliminating the need for a separate altitude encoder.The SV-XPNDR-26X transponder runs from either 14 volt nominal or 28 volt nominal DC powersupply with no configuration changes required.The SV-XPNDR-26X transponder responds to both legacy Mode A/C interrogations and to ModeS interrogations from both ground radar and airborne collision avoidance systems. In all cases,the interrogations are received by the transponder on 1030MHz, and replies are transmitted on1090MHz.Read and understand the System Planning Chapter before installing the SV-XPNDR-26X.Figure 63 has a high-level overview of a suggested SV-XPNDR-26X installation, configuration,and testing procedures:Figure 63 - Suggested SV-XPNDR-26X Installation, Configuration, and Testing ProcedureSkyView System Installation Guide - Revision J 11-1
