D-subminiature Crimp Contacts and Tools
D-subminiature crimp contacts can be obtained from a variety of sources. Dynon recommends
the use of the following Mil Spec types in avionics applications.
Table 52–Recommended D-subminiature Crimp Pins
Use a high quality 4-way indentation contact crimper when working the Mil Spec contacts in
Table 52. Paladin Tools P/N 1440 (for 20 to 26 AWG wire) is an example of such a contact
crimper tool.
Homemade Wire Harness Considerations
Each SkyView display includes its own wire harness (SV-HARNESS-D37) for connection to power,
serial ports, USB, the external battery, and other connections. We recommend that you use this
harness for display installations instead of building your own.
Here are some considerations if you build your own SkyView network wire harnesses.
Wire Insulation
We recommend that all wire harness wires that are installed in aircraft utilize Tefzel® insulation.
Twisted Pairs
SkyView networks utilize two data wire pairs for communication between devices. This guide
refers to these pairs as Data 1 and Data 2 and each have an A and a B wire. These pairs should
have 8 to 10 twists per foot over their entire length.
Heat Shrink Bundling and Strain Relief
All wires should be bundled together with heat shrink and then strain relieved when exiting the
connector shell or hood.
SV-BAT-320 Connection
To connect a homemade harness to an SV-BAT-320, the following specifications must be
followed closely for the SV-BAT-320 to charge and work correctly:
Connector: Molex Micro-Fit P/N 43640-0301 (Digi-Key P/N WM1856-ND)
Pins: Molex Micro-Fit P/N 43031-0007 (Digi-Key P/N WM1841-ND)
Wire: 22 AWG Tefzel, NO MORE THAN 24” LONG; red w/yellow: M22759/16-22-24;
black: M22759/16-22-0
