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.

20, 22, 24
Male/Pin
M39029/64-369
Table 69Recommended D-subminiature Crimp Pins
Use a high quality 4-way indentation contact crimper when working the Mil Spec contacts in
Table 69. 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.
Wire Size
We recommend that all wire harness wires be 22 AWG unless otherwise specified.
Twisted Pairs
SkyView Network cables use twisted data wire pairs for communication between devices. The
wire pair should be twisted at 8-10 twists per foot over the entire length of the cable.
