2-10 SkyView System Installation Guide - Revision K
SkyView Network
Displays and modules utilize standardized 9-pin D-sub (from now on referred to as “D9”)
network connectors and are compatible with premade connection hardware—network cables,
splitters, and connector gender changers. Servos have un-terminated wires and we recommend
the use of one servo cabling kit (SV-NET-SERVO) per servo. All of this connection hardware is
available from Dynon.
Harnesses and Cables
Dynon’s display harness and network cables use aircraft-grade Tefzel® wiring. The display
harness breaks out power, serial, USB and other important pins from the back of the display.
Network cables are available in a variety of lengths. The 3 and 6 foot cables have female D9
connectors on both ends. The longer cables have a female D9 connector on one end and open
pins on the other end. The open end allows installers to run the cable in and through areas that
would not be possible if a connector was present. The connector is installed after the cable has
been run.
The servo cabling kit (SV-NET-SERVO: one kit per servo) makes it easy to connect the SkyView
system to servos and includes 20 feet of pre-twisted wire (twisted pair 22 AWG wire for data;
20 AWG wires for power), D9 connectors, connector shells, crimp contacts, an insertion tool,
heat shrink, and zip ties. It is recommended that you read and understand Appendix C: Wiring
and Electrical Connections before working with this kit.
Splitters and Gender Changers
Splitters (SV-NET-SPL) use aircraft-grade Tefzel® wiring, consist of a male D9 input connector
and two female D9 output connectors, are 1 foot long, and include a connector gender changer
(SV-NET-CHG). They add another module connection point in the network. An example
application for a splitter is the connection of primary and backup ADAHRS in a SkyView network
off one network cable coming from a display. These can also be used when you require more
network connections than the two SkyView connectors that are present on each display,
though the preferred mechanism for adding SkyView connections is the SkyView Network Hub
(described below).
Note that customers that purchased SkyView systems prior to March 2012 are likely to have
splitters for all SkyView network expansion needs. More recent customers are likely to have
fewer splitters (usually, just one at a dual ADARS installation), and one hub.
Connector gender changers allow SkyView network cables to connect to the output connector
of a splitter. This allows a cable split to occur in the middle of a long run of cable.
SkyView Network Hub
The SV-NET-HUB SkyView Network hub contains 5 SkyView Network ports. All 5 ports are
identical. In other words, any of them can be used to connect to your displays, modules, and/or
autopilot servos. Servo power should be broken out, as is normally done. See the Autopilot
Servo Installation section of this manual for more information about Servo wiring. The SkyView
