SkyView Display Installation and Configuration
SkyView System Installation Guide - Revision AA 4-17
Electrical Installation
Use this section in conjunction with the information contained in Appendix C: Wiring and
Electrical Connections (notably Figure 217 on page 23-9). The wires and wire colors in this
section refer to the wires on the included SkyView Display Harness (SV-HARNESS-D37).
Some wires that are used in SkyView harnesses are identified with secondary color
stripes. Exposing these striped wires to solvents or abrasives can cause the stripe
color to wear off. Handle these wires with care.
Power Input
SkyView displays have a primary power input that is compatible with 12 volt and 24 volt
electrical systems (10 to 30 volts DC). There are two unterminated solid red primary power
input wires (to reduce current loading in each wire—these are not for redundancy and both
must be connected to the same power source) and two unterminated solid black primary
ground wires.
Ensure that there is an appropriately rated circuit breaker or replaceable fuse on
the primary power input. Reference the Power Section of the System Planning
Section for more information.
Grounding
Ensure that all external devices that interface with SkyView have a common ground with
SkyView. If a device does not share ground with SkyView, it may not communicate properly.
Airplane Master Contactor / Relay Considerations
If your aircraft is equipped with a master contactor or a relay that is operated by the master
switch, it is imperative that the coil of the contactor or relay is protected by a diode to reduce
the voltage spike seen when the contactor is turned off. Without this diode, the aircraft system
can see spikes above 100V, which can damage Dynon Avionics equipment and other avionics.
While some contactors have this diode internally, many do not. Please verify the existence of
this diode before operating your Dynon Avionics equipment. Any diode that is rated for more
than 1A and more than 50V is suitable. Vans Aircraft part number ES DIODE MASTER is also a
suitable option.
SV-BAT-320 Connection and Operation Rules
SkyView displays have the option of an external backup battery - SV-BAT-320. The SV-HARNESS-
D37 harness has a connector that mates with the connector on the SV-BAT-320. Simply
connecting the display to the battery enables the use of the SV-BAT-320; no additional
configuration is required.
In the event of an electrical failure that causes SkyView to run on the SV-BAT-320, the SV-BAT-
320 supplies power to the SkyView display it is connected to, along with any devices powered
