• A listing of the TAWS/RWS Input Data Signals, LRUs providing those signals, their data
definitions (i.e. Analog signal type, A429 Label, etc.) and the minimum requirements that
must be met by that specific input signal in order for TAWS/RWS to function within
specification.
A. TAWS/RWS Pinout and Pin Descriptions (Non--Configurable)
This section contains the non--configurable pin assignments for the GCAM functionality
(Table 4-- 6).

CAS provides a +5 Vdc
precision reference output as a
reference voltage for analog
sensors which provide a
ratio--metric output. In most
installations the reference
voltage and the signal voltage
are monitored so that the
tolerance of the reference output
is not critical. This is the
preferred method and eliminates
issues such as ground
differentials in aircraft
installations.
