SV-XPNDR-26X Installation, Configuration, and Testing
SkyView System Installation Guide - Revision K 11-3
Secure the mounting tray to the aircraft via the three (3) mounting holes in the tray.
The tray should be mounted to a flat surface - it is important that the tray is supported
at the dimples as well as the three mounting points.
Put the SV-XPNDR-26X transponder into the secured mounting tray by hooking the
connector end under the lip on the tray.
Lock the SV-XPNDR-26X transponder into the mounting tray by clipping the retaining
wire over the lugs on the opposite end.
Additional items you will require, but which are not in the SV-XPNDR-26X package, include:
Antenna and fixing hardware. The SV-XPNDR-26X is compatible with transponder
antennas commonly available.
Cables and male TNC connector. You need to supply and fabricate all required cables.
Guidance on cable types is given below.
Mounting hardware: To secure the transponder tray to the airframe you will need at
least 3 flat head screws and three self-locking nuts. If the aircraft does not have existing
mounting provisions you may need to fabricate additional brackets to support the
transponder tray.
Electrical Connections
Harness Construction
Because the SV-XPNDR-26X can be mounted in a variety of locations, the harness length
requirements will vary from airplane to airplane. Therefore, Dynon Avionics does not supply
pre-manufactured harnesses for the SV-XPNDR-26X. Instead, your SV-XPNDR-26X shipped with
enough connectors and pins to generate a wide variety of harness configurations. Refer to the
sections below for detailed wiring information.
If you do not own a D-sub machined-pin crimping tool, they can be obtained for under $50 from
many retailers. See http://wiki.dynonavionics.com/Tools_not_supplied_by_Dynon for known
sources of these products. You may also find it helpful to own a pin insertion/extraction tool as
well.
Additional harness construction and wiring information can be found in Appendix C: Wiring and
Electrical Connections.
The SV-XPNDR-26X has a single D25 female connector which provides the data and power
inputs to the transponder. A single TNC coaxial connector attaches to the antenna.
