Rev E
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.
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.

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
audio panel to avoid ground loops. Contact audio manufacture for further
instructions.
When installed as a DG, no audio alerting is supported, and this output
should remain disconnected.
In non-metallic, IFR capable aircraft, this connection MUST
remain disconnected due to lightning strike limitations.
10.2.5
GPS Interface (Optional)
The GPS interface is an optional RS-232 serial input that is compatible with
the industry standard “Aviation” output provided by most panel mounted
GPS units, and NMEA serial interfaces provided by most hand-held GPS
units.
