SV-XPNDR-26X Installation, Configuration, and TestingThe hex code needs to be set to the aircraft’s assigned code for the transponder tofunction properly. The default code of 000000 is not a valid code. If the code is leftat 000000, the transponder will only work in SBY mode.VFR CODE: When the pilot presses the VFR button, a pre-programmed code will replacethe current squawk code. The pre-programmed code is set up here; the choice of codewill depend on the normal location of the aircraft. In the USA, the VFR squawk code is1200. In most parts of Europe, the VFR squawk code should be set to 7000.AUTO ALT/GND SWITCH: Allows the transponder to automatically switch betweenAirborne and Ground modes. Available options include:o NONE : Automatic switching disabledo SQUAT SWITCH LOW ON GND: Utilizes a physical squat switch connected the SV-XPNDR-26X per the above instructions. When this option is selected, thetransponder will consider the aircraft to be on the ground when this switch islow (electrically grounded).o SQUAT SWITCH LOW IN AIR: Utilizes a physical squat switch connected the SV-XPNDR-26X per the above instructions. When this option is selected, thetransponder will consider the aircraft to in flight when this switch is low(electrically grounded).o AUTOMATIC (AIR DATA): The transponder automatically determines whether theaircraft is in flight or not by using a combination of GPS and air data changesfrom SkyView. Note that this option only works with transponder software 2.02or above. See the Transponder Software Updates section below for moreinformation about transponder software.AIRCRAFT CATEGORY: To assist ATC tracking of aircraft, an aircraft category can betransmitted by Mode S transponders. Set as appropriate for your aircraft.AIRCRAFT LENGTH and AIRCRAFT WIDTH: On the ground, ADS-B transmits encodedaircraft size information which is used by ATC to identify taxiing routes and potentialconflicts. Using the aircraft length and width (wingspan), in your current distance/speedunits (meters or feet), the SV-XPNDR-26 will calculate the appropriate size code fortransmission.MAXIMUM CRUISE SPEED: Mode S transponders can transmit their maximum airspeedcharacteristics to aircraft equipped with TCAS. This information is used to help identifythreats and to plan avoiding action by the TCAS equipped aircraft. The airspeeds aregrouped in ranges. Set as appropriate for your aircraft.TIS TRAFFIC: Enables the display of TIS traffic on the SkyView Map page when in an areaserved by a TIS-enabled radar. Note that TIS is a Mode S uplink service that is providedby some US approach radars. TIS coverage is limited to the coverage areas of thoseradars; there is no TIS provision outside the USA.
