The OAT probe is automatically detected by the system, and when
detected, allows temperature related parameters to be selected for
display by the pilot.
If the OAT probe is not detected, display of these parameters will
automatically be inhibited.
8.2.4 Audio Output (Optional)
The optional audio panel connection is a low-voltage analog output
that is designed to connect directly to an audio panel (typically a
non-switched input). High power outputs capable of directly driving a
cockpit speaker are not provided.
When installed as a DG, no audio alerting is supported, and this
output should remain disconnected.
8.2.5 GPS Interface (Optional)
The GPS interface is an optional RS-232 serial input that is
compatible with the industry standard "Moving Map" output provided
by most panel mounted GPS units, and NMEA serial interfaces
provided by most hand-held GPS units.
This is a text/binary protocol output by the GPS navigator that
contains situational awareness information such as ground speed,
track, distance to destination, cross track, etc, and is typically utilized
by remote mapping/display products to provide additional pilot
awareness.
This output does not provide IFR compliant lateral or vertical
guidance, therefore all deviation related data presented is for VFR
operations only.
The AV-30-C does no computations or operations on the data
obtained from the GPS navigator, and simply displays the received
data in a textual or graphical format as configured by the pilot.
UAV-1003947-001, AV-30-C, Installation Manual
In non-metallic, IFR capable aircraft, this connection MUST
remain disconnected due to lightning strike limitations.
