SkyView System Installation Guide - Revision AA 20-1
SV-ADAHRS-200/201 Installation and Configuration section earlier in this manual.
SkyView Network Connection
Connect the SV-MAG-236 to the SkyView network using a SkyView Network Cable. To minimize
any potential magnetic interference from the connector, it is recommended to not locate the
connector near the SV-MAG-236. SkyView Network cables made by Dynon Avionics are
available in various lengths, including 6 feet, 10 feet, 15 feet, 20 feet, 25 feet, and 30 feet.
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
pinouts and wire colors.
Remember to configure the network as described in the Network Setup and Status
section after connecting all modules to a display.
When a NETWORK CONFIGURATION is performed, the internal magnetometer of the SV-
ADAHRS-200 (and SV-ADAHRS-201, if installed) is disabled.
When an SV-MAG-236 is installed in a SkyView system, if the SV-MAG-236 fails or
is disconnected, GPS Ground Track (GND TRK) is substituted for magnetic heading
throughout the system.
Dynon Avionics calibrates every SV-MAG-236 during manufacture. After the
aircraft build is complete, an in-aircraft compass calibration must be performed.
Until the on-ground or the in-flight compass calibration is performed, SkyView will
display a Caution message: NEED COMPASS CAL.
SkyView Software v12.0 added an optional in-flight compass calibration procedure. Performing
the in-flight compass calibration after the on-ground compass calibration can increase the
accuracy of the compass’ magnetic heading. The best compass performance will be achieved by
performing the on-ground compass calibration, then performing the in-flight compass
calibration. It is not required that the in-flight compass calibration be performed immediately
after the on-ground compass calibration.
The on-ground compass calibration requires pointing the aircraft in four directions and
acquiring data at each direction. An accurate method of aligning the aircraft with magnetic
North, East, South, and West, such as an airport’s compass rose, is required. During the
compass calibration, the aircraft’s configuration and major systems should be in a state that
resembles flight conditions (i.e., the canopy should be closed, the aircraft’s pitch attitude
matches SkyView’s attitude depiction, the engine should be running, and all electronic devices
used in flight should be on).
