Label 011 communicates the response to the KCPB Query / Setup Label (KCPB Label 027) or on a continuous basis. For
a detailed description of the Query / Continuous Response Label 011 definition see the EGPWS Interface Methodology,
060-4303-000.
6.2.25 Key Press Data (012) – KCPB
KEY PRESS DATA Source: Honeywell TDU/FMS
LABEL (Octal) 012 Units: N/A Max. Range: N/A Approx. LSB: N/A
Data Bits: Discrete word + = N/A Sign Bit: N/A Pad Bits: None
Transmit Interval (mSec): 180 Data Type: Discrete SDI Bits: 0
TDU/FMS key press data will be transmitted using Label 012. The state of the front panel keys will be transmitted
nominally every 180 ms. Keys which are being pressed will be represented as logic “1” in the appropriate bit while non
pressed keys will be registered as logic “0”. For a detailed description of the Key Press / Display Mode Label 012
definition see the EGPWS Interface Methodology, 060-4303-000.
KEY PRESS DATA Source: KCPB Display
LABEL (Octal) 012 Units: N/A Max. Range: N/A Approx. LSB: N/A
Data Bits: Discrete word + = N/A Sign Bit: N/A Pad Bits: None
Transmit Interval (mSec): at least 200 msec Data Type: Discrete SDI Bits: 0
Key press / Display Mode data will be transmitted using Label 012. This is an optional label for KCPB displays. The state
of the front panel keys will be transmitted nominally every 200 ms. Keys which are being pressed will be represented as
logic “1” in the appropriate bit while non pressed keys will be registered as logic “0”. For a detailed description of the Key
Press / Display Mode Label 012 definition see the EGPWS Interface Methodology, 060-4303-000.
