Apollo CNX80 Installation Manual
2.8.8.2 Precision
Approach
P5-68 Precision Appr
The Precision Appr output is grounded when a precision approach is active. Currently, the precision
approach output will be active when the CNX80 nav radio is tuned to a localizer and the VOR/ILS radio
navigation data is selected for display on the CDI. This output may be connected to the ILS Energize input
of an autopilot or flight director to provide higher autopilot gain when the CNX80 is operating in precision
approach mode.
2.8.8.3 Audio Message Active Out
P5-70 Audio Msg Active Out
The Audio Msg Active Out is grounded whenever the CNX80 is playing an audio message or audio tone.
This output is grounded 200 msec prior to playing the message / tone, and remains grounded for 200 msec
following completion of the message / tone.
2.8.8.4 Power Control Out
P7-36 Power Control Out
The Power Control Out is grounded whenever power is applied to the CNX80, and open otherwise.

NOTE
Installations in conformance with the requirements specified in this installation manual do
not require the use of any external switches, since all switches are provided on the CNX80
front panel.
All of the switch inputs duplicate functions available on the front of the CNX80. These can be used to
make the function available remotely.
2.8.9.1 CDI Select Switch
P7-8
Main CDI Select In
The Main CDI Select In is used to toggle between the display of GPS and VOR/ILS information on the
CDI window and remote CDI connected to the Main CDI outputs. A momentary ground on this input
performs the same function as pressing the
CDI

2.8.9.2 Com Flip-Flop Switch
P1-14 Com Flip Flop In
The Com Flip Flop In is used to toggle the active and standby Com frequencies. A momentary ground on
