7.2 ARINC 708A Output
Two channels of ARINC 708A or KCPB (453) data is provided to drive terrain displays for installations that use the
Terrain Awareness display function. Refer to document 060-4303-000, EGPWS Interface Methodology for further KCPB
information. See Category 6 for more details on individual displays.

7.3 Audio
Output
Mode computation outputs generally result in an audio voice alert unless inputs are invalid or one of the audio suppression
discretes is active. The actual output message, or intended message during audio suppression, is sent to the alert lamp
logic for proper output activation.
discretes is active. The actual output message, or intended message during audio suppression, is sent to the alert lamp
logic for proper output activation.
The audio outputs consist of an 8 ohm amplifier and a transformer isolated 600 ohm output. Additional automatic volume
control lowers both outputs a fixed 6 dB below the nominal level on command. Refer to section 4.2.12 and Category 14
for information on volume levels.

for information on volume levels.
Selectable sets of voice alert messages can be defined. Each set is selected by the Voice Menu option in Category 5.
7.4 Discrete
Outputs
Outputs from the various alert mode computations are first processed to determine which lamp outputs to produce. All of
the lamp outputs are driven by solid state switches to ground. These outputs can also be used as discrete drivers for other
devices. All monitor lamp outputs are normally a steady state switch to ground. Various formats of discrete outputs can be
provided as defined in Category 13.

7.4.1 Ground Proximity Alerts Discrete (Lamp) Outputs
Two Lamp formats are defined as a function of the selected I/O Discrete Type of section 5.3.13. For Lamp Format type 1,
only Mode 5 “Glideslope” message will activate the alert lamp output (amber). All other messages will activate the
warning lamp output (red). Note that Mode 6 does not activate any lamp outputs, only voices.

warning lamp output (red). Note that Mode 6 does not activate any lamp outputs, only voices.
With Lamp Format 2, only the messages containing the phrase “Pull Up” will activate the warning lamp output (red). All
other messages will activate the alert lamp output (amber).
other messages will activate the alert lamp output (amber).
The Glideslope Cancel Input Discrete controls the output of the Mode 5 “Glideslope” message. If the Glideslope Cancel
Input Discrete is activated then the caution lamp (amber) and the voice annunciation will be inhibited for the Mode 5
“Glideslope” message.
