3.16 Annunciations - Suspend/Dead Reckoning/NAV Interface
3.16.1 Applicable Part Numbers
All part numbers and software revisions perform all annunciatons - suspend/dead reckoning/NAV
functions.

3.16.2 Function
A.
Suspend
When in the suspend mode, the KSN 7xx will suspend automatic sequencing of waypoints.
SUSPEND ANNUNCIATE: When SUSPEND ANNUNCIATE is active, the KSN 7xx no longer
automatically sequencing waypoints.
automatically sequencing waypoints.
SUSPEND IN: Signals to the KSN 7xx to stop automatic sequencing of waypoints.
B.
Dead Reckoning
The dead reckoning function indicates to the pilot when GPS is not available and the KSN 7xx is
navigating by dead reckoning.
navigating by dead reckoning.
DEAD RECKONING ANNUNCIATE: When DEAD RECKONING ANNUNCIATE is active, the KSN
7xx is navigating via dead reckoning.

CDI Switching Function
CDI SELECT IN: The CDI SELECT IN input pin is used to tell the KSN 7xx whether output
GPS or VLOC information to the external indicator. The input is normally open, with a
momentary GND applied when the switch is pressed. When the KSN 7xx sees this input go
low, it toggles the navigation source on the primary CDI output between GPS and VLOC.

Annunciator Functions
The following outputs are provided to annunciate KSN 7xx conditions. They may be used to
illuminate lamps, engage relays, or be sensed directly by other systems. The term
“illuminated”, as used below, indicates the active low state of the annunciator output.
