Video Wiring Suggestions
All shields should be grounded to the connector at the source, and floating at the
display.
Avoid routing video wiring parallel to:
•
AC wiring
•
Strobe wiring
•
DC motor supply cables
•
Inverter cabling
•
Or any other potential noise source.
S-Video/Composite and Audio Wiring
Recommended cable for s-video/composite and audio purposes is PIC 75 Ohm
Coax, P/N V75268. This is a lightweight, flexible, and low signal loss cable which
meets FAA flammability requirements of FAR 23.1359(d), FAR 25.853(a) and
FAR 25.869(a)(4).
Similar aviation coaxial cable can be used from other vendors, as well.
Some aircraft are prone to AC noise - we recommend adding to the composite
source a 75Ohm video isolation transformer such as Deerfield Laboratory, Inc.
Part No. 162-1 (www.deerfieldlab.com, (650) 632-4090). In most cases this
should be added to the video output of the source.
Power and Ground Wiring
22 AWG wire is recommended for Power and Ground applications.
