Audio Output (Optional); Navigation Interface (Optional) - uAvionix AV-30-E Installation Manual

The sensor reading must be trimmed during the installation process to
compensate for probe-to-probe variations.
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.

9.2.4 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 or unswitched audio input). High power outputs capable of
directly driving a cockpit speaker are not provided.
Other unswitched unmuted inputs can be used but they may need to be
mixed with an existing audio source. Audio shields must be grounded
only at the audio panel to avoid ground loops. Contact the audio panel
manufacturer for further instructions.
When installed as a DG, no audio alerting is supported and this output
should remain disconnected.

9.2.5 Navigation Interface (Optional)

The Navigation Interface is an optional RS-232 serial interface that can
be connected to one of the following:
• "Aviation" output provided by most panel mounted GPS units
UAV-1004234-001, AV-30-E Installation Manual
Rev H
If two displays are connected to the same
probe, the current will be split between the
two and incorrect readings will be shown
by both.
In non-metallic, IFR capable aircraft, this connection MUST
remain disconnected due to lightning strike limitations.
