Dynon Avionics SkyView Classic - DSUB Crimp Contacts and Tools; Non-Dynon Avionics Wire Harness Considerations

DSUB Crimp Contacts and Tools
DSUB crimp contacts can be obtained from a variety of sources. Dynon Avionics recommends
the use of the following Mil Spec types in avionics applications.
Gender
Mil Spec #
Wire AWG
Female/Socket
M39029/63-368
20, 22, 24
Male/Pin
M39029/64-369
Table 111 – Recommended DSUB Crimp Pins
Use a high quality 4-way indentation contact crimper when working the Mil Spec contacts in
Table 111. Paladin Tools P/N 1440 (for 20 to 26 AWG wire) is an example of such a contact
crimper tool.
Non-Dynon Avionics 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 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.
