Rev. 4, Jan/2003 10599I04.CDL Page 1-3
OBS COS: OBS resolver cosine. Nominal input impedance
is 33.8 K ohms (AC) and 100 K ohms (DC).
A/C POWER MONITOR: This pin senses the aircraft power bus voltage.
This high impedance input operates from 0 to
33 V with accuracy of 0.1 V.
CONFIGURATION MODULE: Refer to Section 2.3.6.2
SIGNAL OUTPUTS:
OBI SYNC, OBI CLOCK, & OBI DATA: Honeywell Serial Data containing bearing to
the active waypoint.
DATA LOADER/QUICKTUNETM RS 232 OUT: The Data Loader/QuickTune RS 232 output is
designed to communicate with an IBM
compatible personal computer.
GENERAL RS 232 OUT: The RS 232 output is designed to interface with
certain ARNAV ELTs and certain moving map
displays, and Shadin fuel flow systems (refer to
RS 232 Format Definitions Appendix).
GPS SENSOR RS 232 OUT: The GPS Sensor RS 232 output is a buffered
connection to the GPS sensor (Xpress)
transmitter connection to the host processor. It
is designed to interface with a EGPWS, and for
testing.
