2-12 SkyView System Installation Guide - Revision R

Mounting Requirements

Some SkyView modules include mounting fasteners, while some do not. Mounting fasteners are

included as a convenience and installers are not required to use them. Use sensible mounting

techniques when installing equipment in suitable locations. You should reference individual

equipment chapters for information regarding installation instructions.

SkyView System Construction

Appendix C: Wiring and Electrical Connections contains complete details regarding

pin-outs of all SkyView system component connectors and wire harness colors.

Overview

A SkyView system consists of displays, modules, and connection hardware. Displays manage

power for modules (not servos) and control communication between devices. Modules provide

data to the displays. The connection between displays and modules is referred to as a SkyView

network.

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.
