SV-ADAHRS-20X Installation and Configuration
5-4 SkyView System Installation Guide - Revision K
must be on the bottom. The label must be on the top. Figure 22 shows the correct orientation
of the ADAHRS as it would appear if you were above the aircraft, looking down at it. The
module will not operate properly if it is rotated or inverted in any other orientation.
Dynon does not provide mounting hardware with SV-ADAHRS-20X. The mounting tabs on each
side of the module have holes sized for #10 fasteners, but it is up to the installer to decide how
the ADAHRS will be secured to the aircraft.
We recommend that installers use button-head style non-ferrous fasteners (e.g., stainless steel
or brass) in this location. Follow recommended torque practices when tightening the mounting
hardware. Do not rivet the SV-ADAHRS-20X to the aircraft as this will hinder future removal if
necessary.
Do not use a magnetic driver when installing the ADAHRS. Doing so has the
potential to affect the factory magnetic calibration.
SkyView Network Connection
Connect the ADAHRS module to the SkyView network using the hardware mentioned in the
SkyView System Construction Section or using equivalent hardware.
If you have to install a connector on the end of a network cable, insert all pins into the D9
connector. Refer to Appendix C: Wiring and Electrical Connections for details on connector pin-
outs and wire colors.
Remember to configure the network as described in the Network Setup and Status
section after connecting all modules to a display.
Pneumatic Ports
The AOA, pitot, and static ports on the SV-ADAHRS-20X are equipped with 1/8” NPT Female
fittings. To attach your pitot and static lines to the module, you must use standard 1/8” NPT
male fittings at the end of each of the lines.
SkyView’s attitude calculation requires airspeed from pitot and static. A GPS
source can be used as a backup if the pitot and/or static source fails, but should
not be the primary source.
Do not use ferrous pneumatic fittings.
To install, simply connect your static and pitot sources to the SV-ADAHRS-20X. If you are
performing a retrofit installation, consider “teeing” off of existing lines using a tee fitting.
Reference the sticker on top of the respective module for pneumatic port identification.
