4.3.2 EGPWS Ground Test Procedures (066-01175-x101 only).
This Ground Test Procedure is designed to minimize potential equipment dam-
age and verify proper operation of the Honeywell EGPWS as installed in the air-
craft.
A. Review your aircraft installation drawings against the manufacturer's data
sheets and verify that all necessary connections are included on your draw-
ings and that the pin numbers are in agreement.
B. With all units disconnected and aircraft power off, do a point to point wiring
check using an ohm meter to verify proper wiring interconnect.
C. With all units disconnected, apply aircraft DC power and verify that power is
supplied to the power input pins.
D. Remove power from the aircraft and connect all units.
E. Connect a PC to the RS-232 communications port of the EGPWS unit.
F. Power up the PC, start "WinViews" and select connect.
G. Power up the avionics in the aircraft. You should note the "Not Available"
light ON and you should see INITIALIZATION messages coming from the
EGPWS on your PC. When the messages quit (could be as long as 3 min-
utes for the first application of power) press Control 'Z' on your keyboard.
The PC display should show a '>'.
H. Type 'PS' and the 'return' key on your PC. You should receive several lines
of status messages from the EGPWS. One of the messages should be
'Configuration Module not initialized'. Instructions for programming the con-
figuration module are contained in section 4.2.3.2 of this document. Go to
section 4.2.3.2 at this time and after configuration has been completed,
return to item I below.
I. With your PC communicating with the EGPWS, select 'file' at the top of the
WinViews screen. Select 'Load Command File' and then select the file
named Gagnddtst.cmd. (This file was supplied on your WinsViews Disk).
