This wire is currently used only for SV-EMS-220 modules, but future modules may also
require this signal, so we recommend it be included if you are building your own SkyView
Network cables.
25.4.1 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.
25.4.2 USB Cable (from D37 connector)
The USB cable used in the SV-HARNESS-D37 is a unique part made to Dynon Avionics’
specifications for this application and is not sold separately. Attempting to terminate a
typical USB cable to a “DSUB” connector causes the USB device to perform marginally
(in our experience). For that reason, we recommend that a non-Dynon Avionics version
of the SV-HARNESS-D37 to not include a USB cable. Instead, purchase USB extension
cables to plug into the two (2) USB ports on the back of the SkyView display.
25.4.3 SV-BAT-320 Connection
For warranty replacement, an SV-BAT-320 that is received at Dynon Avionics
with a different connector than the factory-installed connector is not be
eligible for warranty replacement.
To connect a harness (equivalent to SV-HARNESS-D37) not manufactured by Dynon
Avionics 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 (Digi-Key P/N WM1856-ND).
Pins: Molex Micro-Fit (Digi-Key P/N WM1841-ND).
Wire: 22 AWG Tefzel, NO MORE THAN 24” LONG; Red w/Yellow stripe:
M22759/16-22-24; Black: M22759/16-22-0.
