General Electrical Installation Considerations
Complete electrical installation details for installing a SkyView system are in the SkyView System
Installation Guide.
SkyView systems require more electrical power (current) than a Dynon Avionics EFIS or EMS
system - circuit breakers and main wiring, and perhaps even alternator / generator and
batteries may need to be upgraded. Specific power requirements for SkyView units are listed in
the SkyView System Installation Guide. Because of the increased power requirements, little of
the electrical wiring
14
from a Dynon Avionics EFIS or EMS system can be reused.
Unlike a Dynon EFIS unit, SkyView does not have inputs for secondary (EXTERNAL BACKUP
POWER) or tertiary (KEEP ALIVE) power source(s). Should SkyView lose power to its primary
power input pins, a SkyView display will operate from its backup battery (SV-BAT-320).
To balance current draw on the D-Sub connector’s pins, run both red wires, and both ground
wires of the SV-HARNESS-D37 to avionics power and ground, respectively.
Some SkyView modules and accessories receive (redundant, battery-backed
15
) power via
SkyView Network:
SV-ADAHRS-200/201
SV-ARINC-429
SV-EMS-220
SV-GPS-250
16
Other modules must have avionics power connected directly:
SV-ADSB-470
SV-COM-C25
SV-XPNDR-261/262
Autopilot Servos
SkyView Network cables are not included with a SkyView display, and must be ordered (or built)
separately. Dynon sells pre-assembled and semi-assembled SkyView Network cables of varying
lengths, and a kit of wires and connectors for connecting Autopilot servos. Dynon’s SkyView
Network cables have the advantage of having pins crimped, some connectors assembled, and
the data wires pre-twisted as recommended by Dynon. See Dynon’s Product Ordering Guide
and the SkyView System Installation Guide for details on the various SkyView Network cables
that are available.

Servo power requirements are the same in a Dynon Avionics EFIS system and a SkyView system.

If optional SV-BAT-320 battery is installed on at least one SkyView display.

Does not actually use SkyView Network. SV-GPS-250 transmits, receives, and is powered from a dedicated serial
/ power connection on SkyView displays.
